The food production process and quantity estimation
Quantity production turns the menu into meals: forecast covers, plan and indent, pre-prepare, cook, hold and serve, with standard recipes and a production schedule.
The food production process
Records of portions served and left over feed back into the next forecast.
Steps in quantity food production
- 1Forecast the number of covers from past records (attendance, ward census, bookings), the day of the week, season, weather and events.
- 2Fix portion sizes and calculate quantities from standard recipes, stepping them up as needed.
- 3Prepare the indent (requisition) and get stores issued the previous day.
- 4★Write a production schedule: dish, quantity, recipe code, cook responsible, equipment, start and finish times.
- 5Pre-prepare: clean, wash, peel, cut, soak, grind and marinate.
- 6Cook by the standard method, checking temperature, consistency and taste.
- 7Hold at safe temperatures until service; portion with standard utensils.
- 8Serve; then record quantities made, served and left over to improve the next forecast.

Food production systems
| System | How it works | Example |
|---|---|---|
| Conventional | Raw food bought, cooked on site and served soon after | Most hostel and hospital kitchens |
| Commissary (central kitchen) | One central kitchen cooks for many service points; food is carried hot or chilled | Central kitchens supplying school midday meals; airline catering |
| Ready-prepared (cook-chill, cook-freeze) | Food cooked, rapidly chilled or frozen, stored and reheated when needed | Airline catering, large hospitals |
| Assembly-serve | Ready-made foods bought and only assembled, heated and served | Some food-court and fast-food counters |
Quantity estimation for a hostel lunch
A girls' hostel serves lunch to 400 students. Per-head raw amounts (illustrative; each unit fixes its own): rice 120 g, toor dal 30 g, vegetables 150 g (edible), oil 10 g, curd 100 g. Add 5% extra for guests and handling loss. Vegetables lose 20% in trimming. Prepare the indent.
- Portions to prepare = 400 × 1.05 = 420
- Raw rice = 420 × 120 g = 50,400 g = 50.4 kg
- Toor dal = 420 × 30 g = 12,600 g = 12.6 kg
- Vegetables (edible) = 420 × 150 g = 63,000 g = 63 kg; to buy = 63 ÷ 0.80 = 78.75 kg, rounded up to 79 kg
- Oil = 420 × 10 g = 4,200 g = 4.2 kg; curd = 420 × 100 g = 42,000 g = 42 kg
Indent: rice 50.4 kg, toor dal 12.6 kg, vegetables 79 kg (as purchased, rounded up to the next kg), oil 4.2 kg, curd 42 kg.
Forecasting the number of covers
- Use past records of attendance or covers for the same meal and day.
- Allow for holidays, exams, festivals, weekends and weather (fewer students at home-going weekends, more on festival days).
- In hospitals, use the daily ward census and diet orders.
- For events, use confirmed bookings plus a small margin.
- Note menu popularity: a favourite dish draws more takers.
- Compare forecast with actual every day and correct the method.
In a hospital, the forecast comes from the ward census and diet orders each morning; producing just enough means every patient gets the prescribed diet with little waste.
2 marks: “What is forecasting in food production?” Forecasting is estimating the number of covers or portions needed for a meal from past records, day, season and events.
5 marks: “A hostel serves 400 students. With 5% extra and 120 g rice per head, how much rice is needed?” Portions = 400 × 1.05 = 420; rice = 420 × 120 g = 50,400 g = 50.4 kg.
10 marks: “Explain the food production process in a quantity food service unit.” Draw the flow; explain forecasting, quantity calculation, indent, production schedule, pre-preparation, cooking, holding and service; add production systems and a quantity example.
