When you flash freeze any food you must always put it in the refrigerator without covering it with a wrapper. So, you must be careful while putting the food for flash freezing in the refrigerator. Any unpleasant odor or aromas shall alter the flavor of the food.

  3. Now as you put the food on the cookie sheet, spread it out in a single layer. Make sure that the pieces of the food do not stick to each other. The arrangement need not have to be perfect though. A little touch between the pieces at times is perfectly ok. You must ensure to separate the frozen pieces after freezing them. 
  4. Now put the cookie sheet in the freezer. Let it stay there till the time the food freezes to become solid. This freezing time shall depend on the type and also the quantity of food that you have kept. Usually, it takes about an hour or two, to freeze the small pieces of food. But in the case of large pieces of food, it shall take their own time to freeze. Approximately from 4-8 hours, it shall take to freeze. Just allow the food enough time to get it frozen properly. You can leave the food overnight in the freezer. Or even you can also put the food in the freezer in the morning and bring it out by the afternoon. 
  5. Take out the cookie sheet from the freezer and put the frozen food in the containers or the freezer bags. But make sure to not leave the foods unwrapped in the freezer. In doing so, it shall cause them freezer burns. This is the reason why we put the food into something appropriate. It shall help to support the long-term storage in the freezer.

It is then it struck him that preserving food well below the freezing point is a useful way. Using this idea, he started a massive company of frozen food. At the industrial level, this process is performed in large freezers. Foods are usually frozen no sooner than they are picked or prepared. And due to the temperature, they get frozen within a few hours only. After the foods are flash frozen, they can easily be moved to the conventional freezers. In these freezers,the temperatures is near the freezing point and so the food remains solid frozen. 

Even the fishing boats use this technique of flash freezing. It keeps their catch fresh for days till the time they reach the port. In such cases, the fish are cleaned at first and then they are flash-frozen. This method proves to be useful for preserving fruits, vegetables, and crops as well. all you got to do is to reheat when required.
