1 Gilbert Noussitou 20063-1 NUTRITION L3 COOK & CHILL and COOK & FREEZE SYSTEMS

2 Gilbert Noussitou 20063-2 Cook & Chill – Cook & Freeze Both systems are similar; designed to safely and efficiently pre-cook large quantities of foods The most important step is rapid cooling or freezing to prevent growth of micro- organisms

3 Gilbert Noussitou 20063-3 Raw Materials Buy from reputable suppliers. Choose good quality products. Raw materials should be prepared in areas separated from cooking and post cooking areas.

4 Gilbert Noussitou 20063-4 Cook & Chill Storage Rethermalization Service & Distribution Preparation Cooking Portioning Chilling

5 Gilbert Noussitou 20063-5 Cook & Chill Basic Concept Foods are prepared using traditional cooking methods, Foods are quickly chilled to 0°C to 3°C (32°F to 37°C) Foods are refrigerated and reheated for service within 5 days

6 Gilbert Noussitou 20063-6 Cook & Chill Basic Concept The key component of this system is the blast chiller; capable of cooling foods in no more than 90 minutes

7 Gilbert Noussitou 20063-7 Cook & Chill Basic Concept The rate of chilling is influenced by the size, shape, density, weight, moisture content & temperature of the food Three methods: –Cold air circulated at high speed (most common) –Non-oxidizing gases (less common) –Cold liquid (not common)

8 Gilbert Noussitou 20063-8 Cooking The core temperature of food must reach 71°C (160°F) & should be held be held at this temperature for no less than 2 minutes. Check the temperature using a probe thermometer inserted into the slowest heating point, normally the center.

9 Gilbert Noussitou 20063-9 Portioning Most menu items are placed on trays no more than 50 mm (2) deep Large pieces of meat etc., may not chill as quickly as required; the meat should be portioned while hot in packages of 2.5 kg (5 lbs) maximum and no more than 100 mm (4) thick and then chilled.

10 Gilbert Noussitou 20063-10 Blast Chill The rapid chilling process must begin within 30 minutes of cooking being completed. Once in the chiller, the food must be chilled to a core temperature of between 0°C & 3°C (32°F & 38°F) within 90 minutes. Alternatively, the temperature of large joints of meat must be reduced to 10°C (50°F) or below within 150 minutes, and then portioned before final chilling to 0°C & 3°C (32°F & 38°F).

11 Gilbert Noussitou 20063-11 Blast Chill The speed at which chilling takes place will be affected by the shape, size and density of the food, its moisture content, heat capacity and entry temperature. Placing lids on containers or stacking them on top of one another, will increase the chilling time. However, covering food can protect against contamination, and is thus sometimes appropriate, as long as chilling can still be achieved within the time limits.

12 Gilbert Noussitou 20063-12 Blast Freeze The rapid freezing process must begin within 30 minutes of cooking being completed. Once in the freezer, the food must reach a core temperature of at least -5°C (23°F) within 90 minutes, and a subsequent temperature of at least -18°C (0°F).

13 Gilbert Noussitou 20063-13 Storage: General Rules Cook/chill food should be stored in a cabinet or chamber designed for that purpose. All food should be clearly marked with a description, production date and expiration date. A stock rotation system should be enforced (FIFO).

14 Gilbert Noussitou 20063-14 Storage: Chilled Food Pre-cooked chilled food should be stored between 0°C to 3°C (32°F to 38°F) for a period up to 5 days. If storage temperature rises over 4°C (40°F), but no more than 10°C (50°F), the food should be consumed within 12 hours. Should any food in the store exceed its expiration date or reach a temperature over 10°C (50°F), it should be thrown out as it will be unfit for consumption.

15 Gilbert Noussitou 20063-15 Storage: Pre-Cooked Frozen Food Pre-cooked frozen food should be stored at -18°C (0°F) or below. Generally, frozen food may be stored for up to 8 weeks, although certain food can be stored longer

16 Gilbert Noussitou 20063-16 Distribution Frozen foods must be transported to the rethermalization site in controlled conditions. If a product starts to thaw, it must not be refrozen.

17 Gilbert Noussitou 20063-17 Thawing Pre-frozen foods must be fully thawed before regeneration. Thawing must be controlled preferably with the use of a controlled thawing cabinet. Food thawed rapidly in fast thaw cabinets should be consumed within 24 hours. Thawed food must not be refrozen.

18 Gilbert Noussitou 20063-18 Reheating Equipment Appropriate reheating equipment, includes forced air, steam convection ovens and special chill/reheat carts. Traditional types of hot-air ovens may be used, but care must be taken to ensure that exposed areas of food do not become dehydrated. Commercial microwave ovens may also be used, and recommended for the rethermalization of individual or small numbers of meals. Ideally, it is preferable to install matching rethermalization equipment.

19 Gilbert Noussitou 20063-19 Reheating (Rethermalization) Cooked and chilled foods that are to be eaten cold should be consumed within 30 minutes after removal from storage. Reheating must take place close to the point of consumption. The core temperature of the food must reach 71°C (160°F). and be held at this temperature for at least 2 minutes. Reheated food that has cooled should be destroyed. Reheated food should not be refrozen.

20 Gilbert Noussitou 20063-20 Service Once food has been reheated to the required temperature, it should be consumed as soon as possible, and preferably within 15 minutes of reheating. The core temperature of the food should not be allowed to fall below 65°C (150°F).
