Western Cuisine Industrial Engineer key terms

A systematic, preventive food safety management system that identifies biological, chemical, and physical hazards, establishes control measures at critical points, and documents monitoring, corrective actions, and verification to ensure safe production.

A step in the production process where a control measure can be applied and is essential to prevent, eliminate, or reduce a food safety hazard to an acceptable level. Examples include cooking, chilling, and metal detection.

A measurable value that separates acceptable from unacceptable at a critical control point. For example, a minimum cooking temperature of 74°C for poultry or a maximum pH of 4.6 for acidified foods.

The planned sequence of observations or measurements at a critical control point to assess whether a critical limit is being met. It must be timely to allow corrective action before product is affected.

The action taken when monitoring indicates a deviation from a critical limit. It includes restoring control, handling the affected product, and recording the event and outcome for verification.

The application of methods, procedures, tests, and other evaluations, in addition to monitoring, to determine whether the HACCP plan is working effectively. It includes record review, calibration checks, and product testing.

The ratio of the vapor pressure of water in a food to that of pure water at the same temperature. It indicates the amount of water available for microbial growth; most bacteria require aw above 0.91.

A measure of acidity or alkalinity on a scale from 0 to 14, where 7 is neutral. In food, pH influences microbial growth, enzyme activity, and protein functionality; values below 4.6 inhibit many pathogens.

A microorganism, such as Salmonella, Listeria monocytogenes, or Escherichia coli O157:H7, that can cause illness. In food production, controlling pathogens is a primary food safety objective.

The period during which a food product remains safe, retains its intended sensory and nutritional qualities, and meets label claims under specified storage conditions. It is determined by product formulation, processing, and packaging.

A packaging technique that replaces the air inside a package with a specific gas mixture, such as carbon dioxide and nitrogen, to slow microbial growth and oxidative deterioration, thereby extending shelf life.

A packaging method that removes air from the package before sealing, reducing oxygen to inhibit aerobic spoilage organisms and oxidation. It is commonly used for chilled meats and cheeses.

A rapid cooling process that reduces the temperature of hot food from 63°C to 3°C within a specified time, typically 90 minutes or less, to minimize the growth of spoilage and pathogenic bacteria.

A production system in which food is cooked, rapidly chilled, stored at low temperature, and later regenerated for service. It allows large-scale batch production while maintaining safety and quality.

A cooking method where raw or partially cooked food is vacuum-sealed in a pouch and cooked at precisely controlled, relatively low temperatures in a water bath or steam environment for a specified time.

A heat treatment that reduces the number of viable pathogens in food to a level that is unlikely to cause illness, typically by heating to a specific temperature for a set time, such as 72°C for 15 seconds for milk.

The time required at a given temperature to kill a specified number of microorganisms under defined conditions. It is used to design and validate heat processes for food safety.

The temperature change required to change the thermal death time by a factor of 10. It indicates the temperature dependence of microbial inactivation and is used in process calculations.

A procedure to determine the edible portion yield of a raw ingredient after trimming, cooking, and portioning. It is expressed as a percentage and used to calculate accurate recipe costs and portion sizes.

The weight or volume of a food item after all inedible parts, such as bones, fat, and trim, have been removed and the item is ready for cooking or serving. It is used in recipe costing.

The weight or volume of a food item as it is received from the supplier, including inedible parts and packaging. It is the basis for purchasing and for calculating yield percentages.

The practice of consistently serving predetermined quantities of food to control costs, ensure nutritional consistency, and reduce waste. It relies on standardized recipes, scoops, scales, and pre-portioned items.

A recipe that has been tested and formatted to produce a consistent product every time. It includes exact ingredient quantities, preparation steps, portion size, yield, and service instructions.

A management tool that evaluates menu items based on their popularity and contribution margin, classifying them as stars, plowhorses, puzzles, or dogs to guide pricing and menu design decisions.

The difference between an item's selling price and its variable cost, such as food cost. It represents the amount available to cover fixed costs and contribute to profit.

The ratio of the cost of food sold to food sales revenue, expressed as a percentage. It is a key performance indicator for monitoring menu profitability and controlling costs.

A substance, usually a protein, that triggers an immune response in sensitive individuals. In food production, major allergens such as milk, eggs, fish, crustaceans, tree nuts, peanuts, wheat, and soy must be declared on labels.

The unintentional transfer of an allergen from a food containing the allergen to a food that does not, through shared equipment, utensils, surfaces, or hands. It is a key concern in allergen management.

The regulatory requirement to declare the presence of major food allergens on food packaging in a clear and uniform manner, often using a 'contains' statement, to protect allergic consumers.

The process of cleaning and disinfecting food contact surfaces, equipment, and utensils to reduce microorganisms to safe levels. It is a prerequisite program for HACCP and prevents cross-contamination.

The scientific discipline used to evoke, measure, analyze, and interpret reactions to the characteristics of foods and materials as perceived by the senses of sight, smell, taste, touch, and hearing.

The planned and systematic activities implemented within a quality system to ensure that products or services meet specified requirements. In food production, it includes audits, testing, and documentation.

An ongoing effort to improve products, services, or processes through incremental and breakthrough improvements. In food manufacturing, it often uses tools like Lean, Six Sigma, and root cause analysis.

European Union legislation on the hygiene of foodstuffs that sets out general rules for food business operators, including HACCP-based procedures, temperature control, and personal hygiene requirements.

European Union regulation on the provision of food information to consumers, covering labeling, allergen declaration, nutrition declaration, and distance selling. It harmonizes labeling rules across the EU.

A mandatory statement on food labels providing energy value and amounts of fat, saturates, carbohydrate, sugars, protein, and salt per 100 g or 100 ml, and optionally per portion.

The field concerned with protecting the safety, health, and welfare of people engaged in work. In kitchens and food plants, it covers hazard identification, risk assessment, training, and accident prevention.

The systematic process of evaluating potential hazards by considering the likelihood and severity of harm. It is used to prioritize control measures in both food safety and occupational safety.
