Lecture 4 - Food Production

What is food production?

Preparing menu items in the needed quantity and with the desired quality.

What makes quantity food production different from cooking at home?

The large quantity of food being prepared and the need to maintain consistent quality.

What are the four main parts of food production planning?

Input: employees, materials, operations and equipment.

Control: menus, standards, laws and regulations.

Output: meals that meet quality and quantity requirements.

Memory: production records

What is the main goal of production decisions?

To decide how much food to produce while meeting quality standards and controlling costs.

What is forecasting, and why is it important?

Forecasting is estimating future demand. It helps determine how much food to purchase and how much to prepare.

What is the difference between overproduction and underproduction?

Overproduction: making more food than needed, causing waste and extra costs.

Underproduction: making less food than needed, causing customer disappointment, extra labour or expensive substitutions.

What should production records include?

Date and day, meal and service time, events and weather, food items prepared, quantities prepared and quantities served.

What five factors should be considered when choosing a forecasting model?

Cost, accuracy, relevance of past data, lead time and underlying patterns of behaviour

What are the three main types of forecasting models?

Time series: uses patterns over time.

Causal: uses relationships between demand and other factors.

Subjective: relies on opinions and other information.

What is a time series model, and what is one limitation?

It uses past patterns over time to predict future demand. It is useful for short-term forecasting but can struggle with sudden changes.

Examples: moving average and exponential smoothing.

How does the moving average model work?

It averages a set number of recent data points. Each time new data is added, the oldest point is removed and the average is recalculated.

What is exponential smoothing, and how is it different from moving average?

Exponential smoothing gives more weight to recent demand and the latest forecast. It reacts to changes without needing to store large amounts of historical data.

How does the smoothing coefficient (α) affect a forecast?

α close to 1: reacts strongly to recent changes.

α close to 0: creates a smoother, more stable forecast.

What is production scheduling?

Planning the order and timing of tasks needed to prepare a meal.

What are the two stages of production scheduling?

Planning stage: decide how much of each item to prepare and distribute work to supervisors.

Action stage: assign specific items to employees and record preparation start times.

What is discussed at production meetings?

New recipes, employee assignments, overproduction, underproduction, corrective actions and the production schedule

What is ingredient control, and when does it take place?

Managing ingredients to control quality, quantity and costs. It takes place during purchasing, receiving, storage, forecasting and production.

What is ingredient assembly, and what is an ingredient control room (ICR)?

Ingredient assembly is measuring, weighing and gathering ingredients before production. An ICR is a central area where this work is done.

What are the advantages of centralized ingredient control?

It prevents employees from taking too much from storage, lets cooks focus on cooking and portioning, reduces overproduction and underproduction, and helps control costs.

What is a standardized recipe, and why is it important?

A recipe that consistently produces the same quantity and quality of food. It helps maintain consistent results, portion sizes and costs.

What are the three steps of recipe standardization?

1. Recipe verification.

2. Product evaluation.

3. Quantity adjustment.

What are the four phases of recipe verification?

1. Review recipe components.

2. Make the recipe.

3. Verify the recipe yield.

4. Record changes.

What factors are considered during product evaluation?

Appearance, flavour, cost, labour, equipment needs and employee skills.

What are three methods of adjusting recipe quantities?

Factor method, percentage method and direct reading measurement tables

What information should a standardized recipe include?

Food name, total yield, portion size and number, ingredients and amounts, cooking time and temperature, procedures, portioning instructions, serving suggestions and food safety guidelines.

What must be controlled in quantity food production?

Ingredients, production methods, food quality, labour productivity and energy consumption.

When is production planning successful?

When customers are satisfied, food is safe, demand is met and the budget is followed.

What are the four types of heat transfer? Give an example of each.

Conduction: transfer of heat through direct contact, such as a hot pot handle.

Convection: distribution of heat by movement of liquid or gas, such as circulating boiling water.

Radiation: generation of heat by energy waves, such as sunlight warming skin.

Induction: electromagnetic fields excite electrons of metal cooking surfaces.

What is the difference between moist-heat and dry-heat cooking?

Moist Heat: involves the use of water or steam for the cooking process

Dry Heat: heat is conducted by dry air, hot metal, radiation, or a minimum amount of hot fat

What are examples of moist-heat cooking methods?

Boiling, simmering, stewing, poaching, blanching, braising and steaming.

What are examples of dry-heat cooking methods?

Baking, roasting, grilling, broiling, barbecuing and frying.

What is the difference between blanching and boiling?

Blanching: briefly cooks food in boiling water, then the food is removed and cooled.

Boiling: cooks food in rapidly bubbling liquid for a set time.

What is poaching and simmering?

Poaching: cooking by immersing food in hot water and simmered (fish, eggs)

Simmering: Cooking food in liquid below the boiling point (soups, sauces)

What is braising?

Browning food in a small amount of fat, then cooking it slowly in liquid. Commonly used for meat and poultry.

What is steaming?

Cooking food using steam rather than directly submerging it in water.

What is the difference between roasting and baking?

Both use dry heat in an oven.

Roasting: Cooking food (uncovered) by using high dry heat (meat and vegetables)

Baking: Cooking food (covered) by using moderate dry heat (bread, cakes)

Fricasseing

Browning in butter, then simmering in gravy.

Scalding

To heat a liquid to a point where it’s just about to reach the boiling

point.

What is the difference between grilling and griddling?

Grilling: cooking on an open grid over a heat source.

Griddling: cooking on a flat, solid cooking surface.

What is the difference between deep-frying, pan-frying, stir-frying and sautéing?

Deep-frying: food is fully submerged in hot oil.

Pan-frying: food cooks in a moderate amount of oil.

Stir-frying: food is tossed quickly over high heat with a small amount of oil.

Sautéing: food is quickly cooked in a preheated pan with a small amount of oil.

Searing

Browning of food in oil over high heat before finishing in oven

What is scoring, whipping, grating and paring?

Scoring: cutting thin slits into food.

Whipping: beating rapidly to add air and increase volume.

Grating: shredding food using a grater.

Paring: removing the outer layer or skin of food.

What do marinating, blending, chopping, dicing and diluting mean?

Marinating: soaking food in a mixture such as acid, oil or spices.

Blending: thoroughly mixing ingredients.

Chopping: cutting food into small pieces.

Dicing: cutting food into small squares.

Diluting: adding water to make a liquid less concentrated.

What do creaming, folding and greasing mean?

Creaming: mixing until soft and smooth.

Folding: gently combining mixtures while keeping air in the mixture.

Greasing: coating a surface with butter or oil to help prevent sticking.

What are three multifunctional pieces of equipment?

Combi-oven: combines hot circulating air and steam.

Tilting skillet: performs several functions, including frying, griddling and simmering.

Convection-microwave oven: uses convection, microwave energy or both together.

What is the difference between quality control and quantity control?

• Quality control: ensuring food quality stays consistent.

• Quantity control: producing the exact amount of food needed.

What three critical elements must be controlled in quantity food production?

• Time and temperature

• Product yield

• Portion control

A cafeteria prepares 200 chicken portions but sells only 130. What happened, and what are the consequences?

Overproduction. It can cause waste, extra costs, reduced profit and loss of food quality.

A manager averages the last five days of soup sales to predict tomorrow's demand. Which model is being used?

Moving average forecasting.

A hospital wants its soup to taste the same and produce the same number of portions every day. What should it use?

A standardized recipe with consistent ingredients, measurements and preparation procedures.

A foodservice manager uses last month's sales to decide how many sandwiches to prepare tomorrow. What process is being used, and why?

Forecasting, because the manager uses past information to estimate future demand.

A restaurant notices that soup sales increase on cold days. Which forecasting model could help predict soup demand using weather information? Explain why.

A causal model, because it uses the relationship between an outside factor, such as weather, and the demand being forecast.
