Conventional foodservice system

A foodservice operation where food is purchased, prepared, and served in the same facility, usually close to the time it is eaten. Menus stay flexible, but skilled production staff and careful scheduling are required.

Related: Commissary system, Ready-prepared system, Assembly-serve system
Commissary system

A system in which one central kitchen produces large quantities of food that are then transported to satellite serving sites. It captures economies of scale but requires careful transport, holding, and rethermalization procedures.

Related: Conventional foodservice system, Production forecast
Ready-prepared system

Foods are cooked in advance, rapidly chilled or frozen, stored, and later reheated for service. This extends holding time and allows bulk purchasing, but demands strict temperature control and monitoring.

Related: Conventional foodservice system, Temperature danger zone
Assembly-serve system

A system that buys foods already fully prepared, so the operation mainly stores, heats, and serves them. Labor and equipment needs are low, while the operator depends heavily on supplier quality.

Related: Conventional foodservice system, Purchase specification
Standardized recipe

A written formula listing exact ingredients, quantities, preparation steps, yield, and portion size for a menu item. Following it produces a consistent product and makes costing and nutrient analysis reliable.

Related: Production forecast, Food cost percentage
Cycle menu

A menu plan repeated on a set rotation, such as three weeks, before starting over. It simplifies purchasing and production planning while still offering variety across the cycle.

Related: Production forecast, Purchase specification
Production forecast

An estimate of the number of portions of each menu item needed for a given meal or day. It is based on past sales, census, day of week, and special events, and drives purchasing and labor planning.

Related: Standardized recipe, Cycle menu, Par stock
Purchase specification

A written description of the quality, grade, size, packaging, and other requirements a product must meet. It lets suppliers bid on the same item and helps ensure consistent quality on delivery.

Medical nutrition therapy

Nutrition care provided by a registered dietitian, including assessment, diet prescription, counseling, and follow-up, to treat a disease or condition. It is individualized and documented in the medical record.

Related: Nutrition assessment, Nutrition diagnosis
Nutrition screening

A brief, quick check of factors such as weight change, appetite, and diagnosis to identify patients who may be malnourished or at nutrition risk. Those flagged are referred for a full nutrition assessment.

Related: Nutrition assessment, Nutrition diagnosis
Nutrition assessment

The systematic gathering and interpretation of anthropometric, biochemical, clinical, and dietary information about a patient. It establishes the nutrition problem, its cause, and the plan of care.

Related: Nutrition screening, Nutrition diagnosis, Medical nutrition therapy
Dysphagia diet

A texture-modified diet, often paired with thickened liquids, for people with swallowing difficulty. Foods are grouped by texture level and liquids by thickness to reduce choking and aspiration risk.

Related: Enteral nutrition, Nutrition assessment
Consistent carbohydrate diet

A meal plan that spreads a similar amount of carbohydrate across meals and snacks each day. It helps control blood glucose in diabetes and is often used together with carbohydrate counting.

Related: Nutrition assessment, Medical nutrition therapy
Renal diet

An eating pattern for kidney disease that limits sodium, potassium, phosphorus, and often fluid and protein. The exact restrictions depend on lab values, dialysis status, and the individual's treatment plan.

Related: Medical nutrition therapy, Nutrition assessment
Enteral nutrition

Delivery of liquid formula nutrients directly into the stomach or small intestine through a tube. It is used when a person cannot eat enough by mouth but the digestive tract still works.

Related: Dysphagia diet, Medical nutrition therapy
Nutrition diagnosis

A statement, written as a PES statement (problem, etiology, signs and symptoms), that names and describes a specific nutrition problem. It guides the intervention and is monitored and re-evaluated later.

Related: Nutrition assessment, Medical nutrition therapy
HACCP

Hazard Analysis Critical Control Point: a written, seven-principle system that identifies food safety hazards and sets controls at the points where they can be prevented, eliminated, or reduced to safe levels.

Related: Critical control point, Temperature danger zone
Critical control point

A step in food production where a specific control measure can prevent, eliminate, or reduce a food safety hazard to an acceptable level. Each control point has a measurable limit and a monitoring procedure.

Related: HACCP, Temperature danger zone
Temperature danger zone

The range between 41 degrees F and 135 degrees F, where bacteria that cause foodborne illness grow fastest. Potentially hazardous foods should spend as little time as possible in this range.

Related: TCS food, Thermometer calibration
Cross-contamination

The transfer of harmful microorganisms or allergens from one food, surface, or utensil to another. It is prevented by cleaning and sanitizing, separating raw from ready-to-eat foods, and washing hands.

Related: Sanitizing, Allergen cross-contact
FIFO

First in, first out: a storage practice in which the oldest stock is used before newer stock, so nothing sits long enough to spoil. Deliveries are dated and rotated to the front, with new items placed behind.

Related: Inventory turnover, TCS food
TCS food

Food that requires time or temperature control for safety because it supports rapid growth of pathogens. Examples include meat, poultry, dairy, cut produce, and cooked rice; it must be kept out of the danger zone.

Related: Temperature danger zone, FIFO
Sanitizing

Treating a cleaned surface or piece of equipment with heat or a chemical so that disease-causing microorganisms are reduced to safe levels. Cleaning must come first, since soil prevents the sanitizer from working.

Related: Cross-contamination, Allergen cross-contact
Allergen cross-contact

The unintended transfer of a food allergen into a food that should not contain it, for example through shared utensils, fryers, or cutting boards. Even a trace amount can trigger a severe reaction.

Related: Cross-contamination, Sanitizing
Thermometer calibration

Adjusting a thermometer so its reading is accurate, usually by checking it in an ice-water bath at 32 degrees F. Regular calibration keeps cooking and holding temperatures reliable and is required in food safety plans.

A scheduled, documented review of an employee's work against job expectations. It identifies strengths and areas for improvement and sets goals for the next period.

Related: Job description, Progressive discipline
Progressive discipline

A step-by-step process for correcting behavior, usually moving from verbal warning to written warning to suspension and then termination. Each step is documented, and more serious offenses may skip steps.

Related: Performance appraisal, Grievance procedure
Orientation

The initial program that introduces a new employee to the organization's policies, safety rules, benefits, and job site. It differs from training, which teaches the specific skills of the job.

Related: Job specification, Turnover rate
Turnover rate

The percentage of employees who leave and must be replaced during a period, calculated by dividing separations by average headcount. High turnover raises recruiting, training, and food quality costs.

Related: Orientation, Labor cost percentage
Grievance procedure

A formal, step-by-step process that lets employees raise complaints about working conditions or treatment and have them reviewed. It protects fairness and reduces the risk of unresolved conflict.

Related: Progressive discipline, Performance appraisal
Operating budget

A plan of expected revenue and expenses for day-to-day operations over a set period, such as a year. It covers food, labor, and supplies and is compared with actual results each month.

Related: Food cost percentage, Labor cost percentage, Prime cost
Food cost percentage

The cost of food used divided by food revenue, multiplied by 100. It is a key measure of purchasing, production, and portioning efficiency and is compared against a target.

Related: Prime cost, Inventory turnover
Labor cost percentage

Total labor expense, including wages and benefits, divided by revenue and multiplied by 100. It shows how much of each revenue dollar goes to staff and is tracked against a goal.

Related: Prime cost, Turnover rate
Inventory turnover

The number of times inventory is used and replaced during a period, found by dividing food cost by average inventory value. Low turnover suggests excess stock, spoilage risk, and tied-up cash.

Related: Par stock, Food cost percentage, FIFO
Par stock

The predetermined quantity of an item that should be on hand to cover normal use until the next delivery. Ordering is based on the difference between par and current stock.

Related: Inventory turnover, Production forecast
Break-even point

The sales volume at which total revenue equals total costs, so the operation neither profits nor loses. It is used to judge how much volume a new service or price change must generate.

Related: Operating budget, Prime cost
Prime cost

The combined cost of food and labor, usually expressed as a percentage of revenue. Because these two items dominate an operation's expenses, prime cost is watched closely for early warning signs.
