How to Use Blitz Chilling and Deep Freezing to Extend Food Shelf Life
If you work in a professional kitchen, food service or restaurant and need to store food for a long period of time, it is important to know how to extend the shelf life of your food. The two most common methods are blast freezing and shock freezing.
Quickly Immersed in Cold Water
- In blast freezing, food is quickly immersed in cold water to stop the growth of any microorganisms. This allows the food to be kept fresh for 15 to 20 days without problems. Freezing should only be used for foods that have been frozen at least once.
- According to professional chefs wearing men's and women's chef shirts and aprons, the proper use of blast freezing and refrigeration can extend the shelf life of food by weeks to months. This can be an essential tool for professional kitchens looking to reduce waste and cut costs.
Forced Air Freezing to Extend the Shelf Life of Foods
Some foods, such as fruits and vegetables, can be refrigerated quickly and safely with the blast chilling method. This method is ideal for storing tasty foods for several days.
Freezing large quantities of food
- Foods that are suitable for freezing include meat, seafood, poultry, dairy and baked goods. This way, you can extend the shelf life in some cases up to 12 months. When freezing food, always read the instructions on the package carefully.
- When freezing food, there are certain rules that must be followed in order to maintain quality. First, make sure that the food is properly packaged before freezing. This means using containers and packaging materials that prevent air and moisture from entering. Second, food should not be exposed to high temperatures for long periods of time. This will prevent the growth of bacteria and other organisms. Remember to label frozen foods with the date they were frozen.
- If you are looking for a way to extend the shelf life of your food, consider flash freezing or shock freezing. Quick freezing uses cold air or liquid nitrogen to cool food quickly, while shock freezing keeps food at temperatures below 0°C.
- Freeze sauces, soups, broths, etc. in ice cube trays for immediate reuse.
- Liquid foods such as sauces, soups and broths can be frozen intact. These foods should be allowed to cool to room temperature before being placed in the ice cube trays. Sauce cubes can be stored in freezer bags or containers until needed.
- Food should be stored in the freezer at or below 0 degrees Fahrenheit to prevent spoilage.
- When freezing food, the freezer temperature should be maintained at 0 degrees Fahrenheit or below. This keeps food frozen and prevents it from spoiling. This means that food can be kept in the freezer longer without spoiling.
Summary
- In addition to keeping your freezer cool, you should also date all your frozen foods. This will help you know how long they have been in the freezer and when they are ready to eat. By following these tips, you can ensure that your frozen foods are safe and fresh to eat.
- When freezing food, you should also make sure that there is no cross-contamination. This means that raw meat should not be mixed with cooked or frozen foods. In addition, meat should be placed at the bottom of the freezer so that when it freezes, it does not absorb other flavors from the air and the juices do not run onto and contaminate other foods.
- All foods should be labeled with a freeze date so that the expiration date is known.
- Remember to label frozen foods, as it is important to know how long they have been in the refrigerator and when they are ready to be eaten.
Conclusion
If this is not done properly, the chances of the food spoiling and making you sick are very high. To avoid this, always consult an expert before you start freezing or freezer storage, and make sure the staff doing the work is trained.
