Korean Cuisine Industrial Engineer key terms

A preventive food safety system that identifies biological, chemical, and physical hazards at each process step and sets critical control points with limits, monitoring, corrective actions, and verification records. In Korea it is certified and audited under the Food Sanitation Act.

A process step where control can be applied and is essential to prevent, eliminate, or reduce a significant hazard to an acceptable level. Each CCP requires measurable critical limits, defined monitoring frequency, and documented corrective action when limits are exceeded.

Basic hygiene and facility conditions that must exist before HACCP plans can work, covering water quality, pest control, employee health, cleaning, supplier control, and calibration. Weak prerequisites are the most common reason HACCP plans fail in practice.

Transfer of harmful microorganisms or allergens from a contaminated source to safe food through hands, utensils, cutting boards, drip, or shared storage. Prevention relies on color-coded tools, separate work zones, handwashing, and sanitizing between raw and cooked handling.

Checking the internal temperature of food at its thickest or coldest point with a calibrated probe thermometer to confirm cooking sufficiency or cooling speed. Korean standards commonly cite 74°C or higher for reheated and poultry items and rapid cooling to 5°C within set hours.

The temperature range roughly between 5°C and 60°C where bacteria multiply fastest, doubling in as little as twenty minutes. Holding, cooling, and reheating schedules are designed to move food through this band as quickly as possible.

Illness caused by eating food contaminated with pathogens, toxins, or chemicals. Korean outbreaks are frequently linked to norovirus in oysters and kimchi, Salmonella in eggs, and Bacillus cereus in cooked rice left at room temperature.

A rapid surface cleanliness test that measures adenosine triphosphate from organic residue using a swab and luminometer. It gives an immediate pass or fail reading for cutting boards, slicers, and worktables before a visual or microbiological result is available.

The standard handwashing sequence: wet hands, apply soap, rub palms and backs and between fingers and under nails, rinse, dry with a single-use towel, and use sanitizer. Required before work, after toilet use, and after handling raw animal products.

Mandatory periodic medical screening for food handlers under Korean food sanitation law, aimed at detecting typhoid, cholera, and other communicable infections. Workers with vomiting, diarrhea, or open wounds must be excluded from direct food contact.

Mandatory Korean-language labeling on packaged food covering product name, food type, manufacturer, expiry date, storage method, ingredients, allergens, and nutrition declaration. Allergen and origin labeling rules differ for food service versus retail products.

Identifying and controlling the foods that must be declared to guests, such as egg, milk, buckwheat, peanut, soybean, wheat, mackerel, crab, shrimp, pork, peach, and tomato. Kitchens need separate utensils, labeled storage, and menu disclosure to prevent severe reactions.

The sell-by period versus the period within which food remains safe to eat after opening under stated storage. Korea expanded the consumer-expiry system to reduce waste, shifting stock rotation and menu planning assumptions in food service.

The study of the composition, properties, and changes of food components during storage, preparation, and processing. For cooks it explains why meat toughens, vegetables soften, and sauces break, giving a scientific basis for technique.

The swelling and gelatinization of starch granules in water with heat, thickening a liquid and clarifying when starch is fully cooked. Overheating or long holding then causes retrogradation and syneresis, releasing water from the gel.

The re-ordering of gelatinized starch molecules on cooling, making rice and bread firm and stale and pushing water out of the gel. Reheating restores softness only partially, so rice is best held hot rather than cooled and rewarmed.

The unfolding of protein structure by heat, acid, salt, or mechanical action, changing texture and water-holding capacity. It explains egg coagulation, fish muscle setting in surimi, and the tightening of meat in boiling stock.

Browning from reaction between amino acids and reducing sugars under heat, producing aroma and color without enzymes. It needs a dry, hot surface and low moisture, so patting meat dry and preheating a pan directly affects grilled and pan-fried results.

Fatty acids with one or more double bonds, liquid at room temperature and prone to oxidation and rancidity under heat and light. This is why perilla oil and sesame oil are added at the end of cooking rather than used for deep frying.

Microbial conversion of sugars and proteins into acids, alcohols, gases, and flavor compounds. Korean examples include kimchi lactic fermentation, gochujang and doenjang Aspergillus fermentation, and jeotgal salt fermentation, each governed by salt, temperature, and oxygen.

Conversion of sugars to lactic acid by lactic acid bacteria, lowering pH and suppressing spoilage organisms. In kimchi, Leuconostoc and Lactobacillus species drive the sour taste, carbon dioxide, and texture change that determine optimal ripeness.

The macronutrients and micronutrients a menu supplies and the declared values on labels: energy, carbohydrate, sugars, protein, fat, saturated fat, trans fat, cholesterol, and sodium. Food service uses these values for menu labeling and therapeutic diet planning.

Systematic reduction of sodium in recipes and menus while preserving taste and safety, using acid, aromatic vegetables, and umami sources instead of salt. It matters because Korean diets and soups and kimchi supply most dietary sodium.

The structured arrangement of a Korean table by number of side dishes, such as bansang, set with rice, soup or stew, kimchi, and seasoned vegetables. Layout follows the principle of balancing color, temperature, and cooking method around the diner.

Traditional Korean thinking that classifies foods by yin-yang and the five elements and links them to seasons, organs, and balance. It shaped the pairing of cooling and warming ingredients and the five-color plating seen in royal and seasonal cuisine.

Foods eaten on specific seasonal markers of the lunar calendar, such as tteokguk on Seollal, songpyeon on Chuseok, and patjuk on Dongji. They reflect agricultural cycles and remain a basis for seasonal menu and event planning.

The late-autumn communal preparation of large quantities of kimchi for winter, using salted cabbage, chili, garlic, jeotgal, and other seasonings. It is recognized as intangible cultural heritage and is a classic example of preservation and batch production.

Korean fermented condiment family comprising ganjang, doenjang, and gochujang, traditionally made from meju blocks fermented with Aspergillus and Bacillus. Their salt content and umami define the base flavor of most Korean dishes.

The hands-on execution of standardized recipes at scale, including mise en place, portioning, timing, and plating. In volume feeding it depends on written standard recipes and batch scheduling rather than individual cook judgment.

A written, tested formula specifying ingredients, exact quantities, yield, equipment, method steps, portion size, and plating for a menu item. It makes cost, nutrition, and quality consistent across cooks and shifts.

Forecasting demand and scheduling batches, labor, and equipment so food is ready at service time without excess leftovers. It balances cooking capacity against meal counts and uses production sheets and pull systems.

Analysis that plots each menu item by popularity and contribution margin to classify it as star, plowhorse, puzzle, or dog, guiding pricing and deletion decisions. It links menu design directly to profitability and kitchen workload.

Food cost divided by selling price, expressed as a percentage. It is controlled through standard recipes, yield testing, purchase price monitoring, and portion discipline rather than by raising prices alone.

Selling price minus the variable cost of the item, showing how much each sale contributes to fixed costs and profit. Menu decisions based on contribution margin differ from those based on food cost percentage alone.

The standardized edible portion weight or count for one serving after trimming and cooking loss. It converts purchase quantities into servings and is essential for accurate costing and nutrition calculation.

Arranging cooking, refrigeration, washing, and storage equipment to follow the flow of food from receiving to service without backtracking or cross-contact. Good layout reduces walking time, congestion, and contamination risk.

The path workers and food take through the kitchen during preparation and service. Short, one-way movement from raw to cooked areas improves speed and prevents clean and dirty flows from crossing.

Local exhaust systems that capture heat, smoke, grease, and moisture at the cooking source and replace it with make-up air. Correct hood sizing and filter cleaning protect air quality, fire safety, and worker comfort.

Washing and sanitizing tableware through scraping, washing, rinsing, sanitizing by heat or approved chemical, and air drying. Final rinse temperature and sanitizer concentration are the critical checks for microbial control.

Planning and controlling food service operations to deliver safe, nutritious meals within budget, covering menu cycles, procurement, staffing, and quality measurement. School and hospital feeding adds therapeutic and nutritional standards to cost control.

Prevention of work-related illness and injury in the kitchen through hazard assessment, engineering controls, protective equipment, and training. Key risks include burns, slips, cuts, noise, heat stress, and repetitive strain.

Practical safety management in food service: knife handling rules, gas and fire procedures, wet-floor control, lifting technique, and machine guarding. Regular briefings and near-miss reporting reduce accidents more than posters alone.
