What is cook-chill for extended life?
The cook-chill process allows food manufacturers to cook foods and then rapidly chill them and keep them under refrigeration until the consumer is ready to reheat and eat them. It is used to produce convenience foods like sauces and soups, as well as ready meals, curries and other similar items.
Cook-chill is so essential to extended shelf life because the rapid chilling of cooked product through the ‘danger zone’ of 5°C and 60°C hinders bacterial growth.
“The Cook-Chill System was developed as an economical alternative to traditional cook-and-serve methods. Food produced using the system retains the taste, texture and aroma of freshly prepared ingredients, yet may have been produced in large volumes up to 45 days in advance.” (DCN Brochure)
Cook-chill for 5 day shelf life
Cook-chill for 5 day shelf life, on the other hand, refers to the process used by restaurants and other commercial kitchens whereby food is cooked in advance and then refrigerated for up to 5 days.
Shelf life is very dependent on many things post-cooking, such as pack format, storage conditions, temperature, type of product (protein content, water content, acidic). So there’s no hard and fast rule in the restaurant sector regarding the number of days a product will last.
What does a simple cook-chill system look like?
The most basic components of an effective DCN cook-chill system are:
- Steam Jacketed Cooking Kettle: ensures that all times, temperatures and quality parameters are constantly monitored.
- Pump Fill Station: transfers food at 85 – 95°C into cook-chill bags avoiding particulate damage.
- Tumble Chiller: bags are gently circulated in chilled water to rapidly drop the temperature to below 4.5°C in under an hour (product dependent).
The sealed bags are then placed in chilled storage at 1.5 – 4°C and can be stored for up to 45 days.
