Question 1Occupational Safety, Hygiene, and Food Sanitation

In a confectionery kitchen, which practice best prevents cross-contamination between raw egg products and ready-to-eat chocolate decorations?

  1. Wiping utensils with a dry cloth between uses
  2. Rinsing utensils briefly under cold water between tasks
  3. Using separate colour-coded utensils and boards for raw egg work Correct answer.
  4. Storing both in the same refrigerator shelf with covers

Explanation

Separating equipment by colour-coded designation prevents transfer of pathogens such as Salmonella from raw egg to ready-to-eat items. Dry wiping or brief cold rinsing does not remove or kill bacteria and can spread them further. Physical separation of utensils and boards is a recognised control under HACCP-based hygiene systems.

Question 2Occupational Safety, Hygiene, and Food Sanitation

What is the correct handwashing sequence for a confectionery worker before handling ganache?

  1. Apply soap, wet hands, scrub, dry with cloth
  2. Wet hands, apply soap, scrub including fingertips and nails, rinse, dry with disposable towel Correct answer.
  3. Wet hands, scrub with water only, air dry
  4. Apply sanitizer, then rinse with warm water

Explanation

Effective handwashing requires wetting, soaping, thorough scrubbing of palms, backs, fingertips and nails, rinsing, and drying with a disposable towel. Cloth towels can recontaminate hands and harbour organisms. Sanitizer is not a substitute for removing soil and grease from hands.

Question 3Occupational Safety, Hygiene, and Food Sanitation

A worker in a chocolate tempering room develops vomiting and diarrhoea. What is the correct immediate action?

  1. Switch to cleaning duties only
  2. Report to the supervisor and be excluded from food handling Correct answer.
  3. Take medication and resume work after one hour
  4. Continue working but wear double gloves

Explanation

Staff with vomiting or diarrhoea must report symptoms and be excluded from food handling because pathogens such as norovirus spread easily via hands and surfaces. Gloves or reassignment to cleaning do not remove the risk of contaminating food or contact surfaces. Exclusion until symptom-free for the required period is standard practice.

Question 4Occupational Safety, Hygiene, and Food Sanitation

Which temperature range represents the danger zone in which bacteria multiply most rapidly in cream fillings?

  1. 0°C to 4°C
  2. 70°C to 100°C
  3. 5°C to 63°C Correct answer.
  4. -18°C to -10°C

Explanation

The danger zone is broadly 5°C to 63°C, where bacterial growth is fastest. Frozen and chilled ranges slow growth, and temperatures above 70°C generally kill or inactivate many vegetative pathogens. Cream fillings should therefore be held outside the danger zone during preparation and display.

Question 5Occupational Safety, Hygiene, and Food Sanitation

Which is the correct way to store cleaning chemicals in a confectionery production area?

  1. Decanted into empty syrup bottles
  2. In the same cupboard as food colourings
  3. In unlabelled spray bottles near the workbench
  4. In a locked cabinet away from food, in original labelled containers Correct answer.

Explanation

Chemicals must be kept in clearly labelled original containers in a separate locked store away from food to prevent accidental contamination or misuse. Unlabelled or repurposed bottles create a serious poisoning risk. Storage alongside food ingredients is never acceptable.

Question 6Occupational Safety, Hygiene, and Food Sanitation

A baker notices a small cut on their finger before starting a marzipan batch. What is the appropriate control?

  1. Wrap with cling film
  2. Cover with a brightly coloured waterproof detectable plaster and wear a glove Correct answer.
  3. Cover with a fabric plaster and continue
  4. Leave it uncovered so air can dry it

Explanation

Wounds must be covered with a waterproof, detectable plaster, often in a bright colour, and a glove worn to keep the dressing secure and visible. This prevents both contamination of the product and loss of the plaster into food. Fabric plasters and improvised coverings are not adequate.

Question 7Occupational Safety, Hygiene, and Food Sanitation

Which document must be completed to show that a batch of fondant has been cooled and stored within safe limits?

  1. Supplier invoice
  2. Purchase order
  3. Temperature monitoring record Correct answer.
  4. Staff rota

Explanation

Temperature monitoring records provide documented evidence that cooling and storage stayed within safe limits, supporting due diligence. Purchase orders, rotas and invoices do not record process temperatures. Accurate records are a core part of HACCP verification.

Question 8Occupational Safety, Hygiene, and Food Sanitation

A confectioner is cooling a large batch of custard for a cream filling. Which method best meets safe cooling practice?

  1. Place the hot pot directly into a cold store
  2. Divide into shallow trays and cool rapidly to below 8°C within about 90 minutes Correct answer.
  3. Leave it in a deep pot at room temperature overnight
  4. Add ice cubes directly into the custard

Explanation

Rapid cooling in shallow layers increases surface area and shortens the time spent in the danger zone, limiting bacterial growth. Cooling a deep pot slowly at room temperature or in a cold store puts the whole mass through the danger zone for too long. Adding ice directly introduces water and potential contamination.

Question 9Occupational Safety, Hygiene, and Food Sanitation

Which statement correctly describes the role of a critical control point in a chocolate production HACCP plan?

  1. A step where a hazard can be prevented, eliminated or reduced to an acceptable level Correct answer.
  2. A record kept for financial auditing
  3. A step performed only by supervisors
  4. Any point where quality is checked visually

Explanation

A critical control point is a step at which control can be applied to prevent, eliminate or reduce a significant hazard to an acceptable level. It is defined by hazard analysis, not by visual quality checks or staff seniority. Monitoring at that step must be measurable and have defined critical limits.

Question 10Occupational Safety, Hygiene, and Food Sanitation

A worker must clean a nougat mixer between allergen-containing and nut-free batches. Which approach is most appropriate?

  1. Follow a validated cleaning procedure with detergent, rinse and inspection Correct answer.
  2. Brush out visible residue only
  3. Rinse with cold water and dry with a cloth
  4. Run the mixer empty for a few minutes

Explanation

Allergen control requires a validated cleaning procedure that physically removes protein residues, followed by inspection or verification such as allergen swabs. Rinsing, brushing or dry running does not reliably remove allergenic residues. Validation confirms the method actually works for that equipment.

Question 11Occupational Safety, Hygiene, and Food Sanitation

Why is a metal detector placed at the end of a chocolate bar line?

  1. To detect and reject product containing metal fragments from equipment Correct answer.
  2. To weigh the finished bars
  3. To count production output
  4. To check the temper of the chocolate

Explanation

A metal detector at the end of the line acts as a physical hazard control, rejecting product that may contain fragments from worn machinery. It does not measure weight, temper or output. Regular challenge testing with test pieces verifies that it is working.

Question 12Occupational Safety, Hygiene, and Food Sanitation

A worker uses a sanitiser on a food contact surface. What must be confirmed before use?

  1. That it is approved for food contact surfaces and used at the correct concentration and contact time Correct answer.
  2. That it is diluted with hot water only
  3. That it is the cheapest available product
  4. That it smells strongly

Explanation

Sanitisers must be approved for food contact use and applied at the specified concentration and contact time to be effective. Smell, price or water temperature are not indicators of efficacy. Incorrect dilution either fails to sanitise or leaves harmful residues.

Question 13Occupational Safety, Hygiene, and Food Sanitation

Which practice correctly manages pest control in a sugar store?

  1. Leaving spilled sugar on the floor to be swept weekly
  2. Using rodenticide baits inside the ingredient store
  3. Storing ingredients on pallets away from walls with regular pest monitoring Correct answer.
  4. Keeping doors open for ventilation during production

Explanation

Ingredients should be stored off the floor and away from walls to allow inspection and prevent harbourage, supported by regular pest monitoring. Spilled sugar attracts pests, open doors allow entry, and rodenticides should not be placed where they could contaminate ingredients.

Question 14Occupational Safety, Hygiene, and Food Sanitation

A confectioner handles nuts and then prepares a nut-free meringue for an allergic customer. Which control is essential?

  1. Changing apron only
  2. Wiping hands on a dry towel
  3. Rinsing hands in sanitizer only
  4. Washing hands and changing gloves and apron, and using cleaned equipment Correct answer.

Explanation

Allergen cross-contact is controlled by washing hands, changing gloves and apron, and using equipment that has been cleaned of nut residues. A partial measure such as changing only the apron leaves hands and equipment contaminated. Sanitizer alone does not remove allergenic proteins.

Question 15Occupational Safety, Hygiene, and Food Sanitation

Which condition most favours the growth of xerophilic moulds on high-sugar confectionery such as fondant?

  1. Storage below 0°C
  2. Storage in a dry, cool room
  3. Storage in a warm, humid environment with condensation Correct answer.
  4. Storage in sealed metal tins

Explanation

High-sugar products have low water activity, but xerophilic moulds can still grow when surface moisture increases through condensation in warm, humid conditions. Dry, cool storage and sealed containers help prevent moisture uptake. Sub-zero storage and sealed tins do not promote condensation on the product.

Question 16Occupational Safety, Hygiene, and Food Sanitation

Which statement about water activity and microbial stability in ganache is correct?

  1. Higher water activity makes products safer
  2. Water activity has no relation to spoilage
  3. Lower water activity generally restricts microbial growth Correct answer.
  4. Only pH determines spoilage

Explanation

Water activity measures available water for microorganisms; lowering it restricts growth of most bacteria and moulds. Higher water activity supports growth, and pH is only one of several factors affecting spoilage. Formulation and storage conditions together determine shelf stability.

Question 17Occupational Safety, Hygiene, and Food Sanitation

A worker must enter a high-care confectionery packing room. Which sequence reflects good hygiene practice?

  1. Change into clean protective clothing, wash hands, then enter Correct answer.
  2. Wear outdoor shoes and change only the apron
  3. Enter first, then wash hands at the packing station
  4. Put on gloves without washing hands

Explanation

High-care areas require changing into designated clean protective clothing and effective handwashing before entry. Entering first and washing inside defeats the barrier, and outdoor shoes or gloves over unwashed hands introduce contamination. Segregation of footwear and clothing is a standard barrier control.

Question 18Occupational Safety, Hygiene, and Food Sanitation

During an internal audit, a batch of truffles is found with no recorded tempering or storage temperatures. What is the most appropriate corrective action?

  1. Record temperatures retrospectively from memory
  2. Discard the records and continue
  3. Hold the batch, investigate, assess safety and document the corrective action Correct answer.
  4. Sell the batch at a discount

Explanation

Missing records mean the batch cannot be verified as safe, so it should be held pending investigation, with the outcome and corrective action documented. Discounting or fabricating records undermines due diligence and traceability. Corrective action must also address why records were missing.

Question 19Occupational Safety, Hygiene, and Food Sanitation

Which design feature of a confectionery production room most reduces the risk of bacterial harbourage?

  1. Porous concrete floors with cracks
  2. Smooth, impervious, coved surfaces with adequate drainage Correct answer.
  3. Exposed pipework with horizontal ledges
  4. Wooden work surfaces with joints

Explanation

Smooth, impervious surfaces with coved junctions and good drainage prevent soil and moisture accumulating in crevices where bacteria harbour. Porous concrete, wood and horizontal ledges create niches that are difficult to clean. Hygienic design supports effective cleaning and disinfection.

Question 20Occupational Safety, Hygiene, and Food Sanitation

A worker is decanting hot caramel from a large boiling pan. Which combination best controls the burn risk?

  1. Working quickly without eye protection
  2. Lifting the pan manually without protection
  3. Using appropriate protective gloves, a ladle or pump, and a clear working area Correct answer.
  4. Asking a colleague to hold the pan by hand

Explanation

Hot sugar syrups cause severe burns, so controls include heat-resistant protective gloves, mechanical transfer such as a ladle or pump, and a clear, stable working area. Manual lifting, rushing and hand-holding by colleagues increase the risk of spills. Risk assessment should also consider splash protection.

Question 21Occupational Safety, Hygiene, and Food Sanitation

Which statement best explains why flour dust in a confectionery mixing area is a safety concern beyond hygiene?

  1. Fine dust can form an explosive atmosphere and is also a respiratory sensitiser Correct answer.
  2. It increases the sugar content of the air
  3. It makes the floor slippery only
  4. It changes the colour of the product

Explanation

Fine flour dust can form an explosive atmosphere when dispersed in sufficient concentration, and repeated inhalation can cause occupational asthma. Controls include local exhaust ventilation, enclosure and housekeeping. Slipping, colour change and sugar content do not capture the principal hazards.

Question 22Occupational Safety, Hygiene, and Food Sanitation

A confectionery uses a reduced-oxygen packaging line for a moist bakery product. Which risk must be specifically controlled?

  1. Increased vitamin content
  2. Growth of anaerobic pathogens such as Clostridium botulinum and packaging integrity Correct answer.
  3. Growth of aerobic moulds only
  4. Faster colour development

Explanation

Reduced-oxygen packaging removes the inhibitory effect of oxygen on anaerobes, so pathogens such as Clostridium botulinum become a specific concern, alongside maintaining seal integrity. Aerobic moulds are suppressed rather than favoured. The product formulation and chilled storage must be designed to control the anaerobic risk.

Question 23Occupational Safety, Hygiene, and Food Sanitation

A supplier delivers cocoa butter with a broken seal and evidence of pest activity. What is the correct action under a supplier assurance programme?

  1. Use only after sieving the cocoa butter
  2. Accept and use immediately to avoid delays
  3. Reject the delivery, record the non-conformance and notify the supplier Correct answer.
  4. Accept but store in a separate area

Explanation

A broken seal with pest evidence means the ingredient cannot be verified as safe, so it should be rejected and the non-conformance recorded and reported to the supplier. Accepting it, even in separate storage, introduces a hazard, and sieving does not address contamination or traceability. Supplier approval and monitoring depend on such records.

Question 24Occupational Safety, Hygiene, and Food Sanitation

Which approach best verifies that a cleaning regime for allergen removal is effective?

  1. Smelling the surface for residues
  2. Checking that the cleaning log is signed
  3. Specific allergen swab or protein tests on cleaned surfaces, with documented results Correct answer.
  4. Visual inspection alone after cleaning

Explanation

Visual inspection cannot detect protein residues, so allergen-specific swabs or protein tests provide objective verification that cleaning has removed allergenic material. A signed log only shows the task was recorded, not that it worked. Verification results should be documented and trended.

Question 25Raw Materials and Ingredient Science

In chocolate manufacture, which sugar is added to counteract the natural acidity of cocoa solids and round out flavour?

  1. Lactose
  2. Dextrose
  3. Sucrose Correct answer.
  4. Fructose

Explanation

Sucrose is the standard sweetener in chocolate because it is readily available, stable and its sweetness balances cocoa's bitterness without masking it. It also influences viscosity and snap in the finished bar. Other sugars are used only in specialty formulations.

Question 26Raw Materials and Ingredient Science

Which property of cocoa butter makes it the ideal continuous fat phase for tempered chocolate?

  1. It melts sharply near body temperature and crystallises in stable polymorphs Correct answer.
  2. It contains high levels of free fatty acids
  3. It emulsifies readily with water
  4. It is highly unsaturated and stays liquid at room temperature

Explanation

Cocoa butter is dominated by symmetric triglycerides that crystallise in a narrow polymorphic range and melt just below body temperature. This gives chocolate its snap and clean melt. Its low unsaturation and low free fatty acid content also support stability.

Question 27Raw Materials and Ingredient Science

In sugar confectionery, what is the primary role of glucose syrup in a boiled sweet formulation?

  1. It adds colour to the candy
  2. It inhibits crystallisation of sucrose Correct answer.
  3. It increases the sweetness intensity
  4. It provides leavening

Explanation

Glucose syrup contains a mixture of saccharides that interfere with sucrose crystal lattice formation, preventing graining in boiled sweets. It also controls hygroscopicity and modifies texture. Sweetness contribution is secondary.

Question 28Raw Materials and Ingredient Science

Which ingredient is added to fondant to control the size and number of sucrose crystals?

  1. Glucose syrup Correct answer.
  2. Invertase
  3. Citric acid
  4. Gelatin

Explanation

Glucose syrup acts as a crystallisation inhibitor by interfering with sucrose lattice growth, keeping fondant crystals small. Small crystals produce the smooth, creamy texture characteristic of fondant.

Question 29Raw Materials and Ingredient Science

Which type of gelatin is most commonly used in gummy confectionery?

  1. Acid-hydrolysed gelatin
  2. Type A gelatin
  3. Type B gelatin Correct answer.
  4. Enzymatically hydrolysed collagen

Explanation

Type B gelatin, produced by alkaline hydrolysis of collagen, is widely used in gummies because of its consistent gel strength, clarity and low odour. Type A is acid-processed and used in some applications but is less common in gummies.

Question 30Raw Materials and Ingredient Science

Which leavening agent is typically used to aerate a nougat or marshmallow formulation?

  1. Sodium bicarbonate
  2. Egg albumen Correct answer.
  3. Sodium chloride
  4. Potassium sorbate

Explanation

Egg albumen proteins denature and form a foam that holds air during whipping, giving nougat and marshmallow their light, porous structure. Chemical leavening is not the primary aeration route for these confections.

Question 31Raw Materials and Ingredient Science

What is the primary function of lecithin in chocolate?

  1. It sweetens the chocolate
  2. It inhibits fat bloom
  3. It provides the snap on breaking
  4. It reduces viscosity and controls flow Correct answer.

Explanation

Lecithin is an emulsifier that reduces the viscosity of molten chocolate by improving the dispersion of sugar and cocoa particles, allowing lower fat content or better flow for moulding and enrobing. It does not provide sweetness or snap.

Question 32Raw Materials and Ingredient Science

Which milk ingredient is commonly used in milk chocolate to provide dairy flavour and contribute to Maillard browning notes?

  1. Cream
  2. Skimmed milk powder Correct answer.
  3. Buttermilk
  4. Whey protein isolate

Explanation

Skimmed milk powder is the standard dairy ingredient in milk chocolate. Its lactose and milk proteins participate in Maillard reactions during conching and roasting, contributing cooked and caramel notes.

Question 33Raw Materials and Ingredient Science

A confectioner observes that a batch of caramel has become grainy. Which change to the formulation is most likely to prevent this?

  1. Add a small amount of glucose syrup or invert sugar Correct answer.
  2. Increase the sucrose content and reduce the glucose syrup
  3. Increase the final cooking temperature
  4. Stir the mixture vigorously during cooling

Explanation

Graininess indicates uncontrolled sucrose crystallisation. Adding glucose syrup or invert sugar introduces other saccharides that interfere with crystal growth, keeping the caramel smooth. Stirring during cooling can also promote crystallisation.

Question 34Raw Materials and Ingredient Science

A chocolate maker wants to reduce the viscosity of molten chocolate without increasing cocoa butter. Which additive is most effective?

  1. Cocoa powder
  2. Lecithin Correct answer.
  3. Salt
  4. Additional sugar

Explanation

Lecithin reduces viscosity by improving particle dispersion and lowering yield value. It is the standard additive for this purpose in chocolate manufacture. Other ingredients would increase solids or alter flavour without improving flow.

Question 35Raw Materials and Ingredient Science

Which sugar alcohol is commonly used in sugar-free hard candies because of its low hygroscopicity and good sweetness?

  1. Xylitol
  2. Sorbitol
  3. Maltitol Correct answer.
  4. Erythritol

Explanation

Maltitol is widely used in sugar-free hard candies because it provides good sweetness, acceptable glass transition behaviour and lower hygroscopicity than sorbitol. It also gives a texture close to sucrose-based candy.

Question 36Raw Materials and Ingredient Science

A gummy formulation is too soft and lacks springiness. Which change is most appropriate?

  1. Reduce the gelatin bloom strength
  2. Add more glucose syrup
  3. Increase the gelatin concentration or bloom strength Correct answer.
  4. Increase the water content

Explanation

Gel strength and concentration determine the firmness and elasticity of gummies. Increasing gelatin bloom strength or concentration raises the gel network density and improves springiness.

Question 37Raw Materials and Ingredient Science

Why is invert sugar used in some fondant and cream formulations?

  1. It increases hygroscopicity and helps control crystallisation Correct answer.
  2. It acts as a preservative
  3. It promotes large crystal growth
  4. It reduces sweetness

Explanation

Invert sugar is hygroscopic and interferes with sucrose crystallisation, helping keep fondant smooth and moist. It also contributes to sweetness and flavour. Its role is primarily textural and crystallisation-related.

Question 38Raw Materials and Ingredient Science

Which cocoa butter polymorph is the stable form sought in well-tempered chocolate?

  1. Form V Correct answer.
  2. Form VI
  3. Form III
  4. Form I

Explanation

Form V is the stable polymorph that gives chocolate its glossy surface, snap and resistance to bloom. Tempering is designed to maximise Form V crystals. Form VI is even more stable but develops slowly and produces a duller product.

Question 39Raw Materials and Ingredient Science

In a marshmallow formulation, what is the main role of glucose syrup?

  1. It lowers the gel strength
  2. It acts as a preservative
  3. It provides the foam structure
  4. It prevents sucrose crystallisation and controls texture Correct answer.

Explanation

Glucose syrup inhibits sucrose crystallisation and helps control the texture and moisture of marshmallow. The foam structure is provided by whipping proteins such as gelatin or egg albumen.

Question 40Raw Materials and Ingredient Science

Which fat is commonly used as a cocoa butter equivalent in confectionery coatings?

  1. Shea butter stearin Correct answer.
  2. Coconut oil
  3. Palm kernel oil
  4. Cocoa butter

Explanation

Shea butter stearin is a common cocoa butter equivalent because its triglyceride composition is compatible with cocoa butter and supports similar polymorphic behaviour. It is used in coatings and compound products.

Question 41Raw Materials and Ingredient Science

A caramel is too dark and bitter after cooking. Which change is most likely to correct the problem?

  1. Increase the glucose syrup content
  2. Add more sodium bicarbonate
  3. Increase the cooking temperature
  4. Reduce the cooking temperature or time Correct answer.

Explanation

Excessive darkness and bitterness in caramel result from over-caramelisation or Maillard browning. Reducing temperature or time limits these reactions and preserves a lighter flavour.

Question 42Raw Materials and Ingredient Science

Which ingredient is used as a whipping agent in nougat to stabilise the foam?

  1. Pectin
  2. Egg albumen Correct answer.
  3. Starch
  4. Gelatin

Explanation

Egg albumen is a classic whipping agent in nougat because its proteins form a stable foam when whipped. Gelatin can also contribute, but albumen is the primary aerating protein in nougat.

Question 43Raw Materials and Ingredient Science

Why is citric acid added to some fruit-flavoured hard candies?

  1. To act as a preservative
  2. To adjust acidity and enhance fruit flavour Correct answer.
  3. To increase sweetness
  4. To promote crystallisation

Explanation

Citric acid lowers pH and balances sweetness, enhancing perceived fruit flavour. It also contributes to the tartness characteristic of fruit candies. It is not primarily a preservative in this context.

Question 44Raw Materials and Ingredient Science

Which factor most affects the bloom strength of gelatin?

  1. The molecular weight and concentration of collagen-derived proteins Correct answer.
  2. The pH of the final product
  3. The colour of the gelatin
  4. The moisture content of the powder

Explanation

Bloom strength reflects the gel-forming ability of gelatin, which depends on the molecular weight and concentration of collagen-derived proteins. Higher molecular weight and concentration generally yield higher bloom strength.

Question 45Raw Materials and Ingredient Science

In chocolate refining, what is the main purpose of the refiner?

  1. To temper the chocolate
  2. To add lecithin
  3. To remove moisture
  4. To reduce particle size of sugar and cocoa solids Correct answer.

Explanation

Refining reduces the particle size of sugar and cocoa solids to a smooth, fine dispersion, which is essential for mouthfeel. Tempering and lecithin addition occur at later stages.

Question 46Raw Materials and Ingredient Science

A confectioner wants a chewy, non-crystalline texture in a nougat. Which combination best supports this?

  1. High glucose syrup with controlled moisture and whipping Correct answer.
  2. High fat with low sugar
  3. High gelatin with low whipping
  4. High sucrose with low glucose syrup

Explanation

A chewy nougat texture depends on a high proportion of glucose syrup to inhibit crystallisation, controlled moisture to maintain chewiness, and whipping to incorporate air. This combination prevents graining while building structure.

Question 47Raw Materials and Ingredient Science

Which statement best explains why lauric fats such as coconut oil are avoided in cocoa butter-based chocolate?

  1. They are incompatible with cocoa butter and cause bloom or softening Correct answer.
  2. They contain too much cocoa solids
  3. They are too hard at room temperature
  4. They inhibit tempering by raising the melting point

Explanation

Lauric fats have triglyceride structures incompatible with cocoa butter, leading to eutectic effects, softening and bloom. Their presence disrupts the cocoa butter crystal network.

Question 48Raw Materials and Ingredient Science

A sugar-free hard candy made with maltitol syrup crystallises during storage. Which factor is most likely responsible?

  1. Too much lecithin
  2. Excessive gelatin
  3. Excess glucose syrup
  4. Moisture pickup and insufficient crystallisation inhibition Correct answer.

Explanation

Sugar-free hard candies are prone to crystallisation when moisture is absorbed or when the polyol system lacks sufficient crystallisation inhibitors. Controlling water activity and formulation is essential.

Question 49Raw Materials and Ingredient Science

Which interaction explains why adding too much lecithin can increase chocolate viscosity?

  1. Lecithin reacts with sugar to form crystals
  2. Excess lecithin forms micelles that disrupt particle dispersion Correct answer.
  3. Lecithin absorbs cocoa butter
  4. Lecithin increases the melting point of cocoa butter

Explanation

At excessive levels, lecithin can form micellar structures that interfere with the dispersion of solids, paradoxically raising viscosity. Optimal dosage is therefore critical in chocolate formulation.

Question 50Raw Materials and Ingredient Science

Which property of cocoa butter is most directly responsible for the snap and gloss of well-tempered chocolate?

  1. Its high content of lauric acid
  2. Its resistance to oxidation
  3. Its ability to crystallise in the stable beta polymorph Correct answer.
  4. Its low melting point

Explanation

Cocoa butter must crystallise in the stable beta (Form V) polymorph to give chocolate its characteristic snap, gloss, and resistance to bloom. Lauric acid content, low melting point, and oxidation resistance are not the primary determinants of these textural properties.
