How to set the temperature of various foods during refrigerated transportation

Optimum temperature of different foods during transportation in refrigerated trucks.

1. Fruit and vegetable fresh-keeping area: in the cold storage temperature area of 2 ~ 8℃, vegetables, fruits, eggs, beer, drinks, etc. Can keep fresh and original flavor. Fruits suitable for transportation in this temperature range include grapes, apples, cherries, plums, melons, pears, oranges, peaches, pineapples, lemons and bananas. Fresh vegetables: western Tricholoma matsutake, asparagus, carrots, cauliflower, green peas, cauliflower, cabbage, celery, lettuce, cucumber, eggplant, spinach, potatoes, onions, sweet potatoes, pumpkins and tomatoes.

2. Fresh-keeping area of meat and fish: The food in the 0℃ heat preservation area of 0 ~ 2℃ is kept at 0℃ without freezing and loss of nutrition. Fresh fish and meat that can be eaten for 1-2 days can be stored for a short time, and the freshness is not discounted. Generally, fresh meat is suitable for this temperature range: raw bacon, raw pork, raw beef, raw chicken, raw mutton, raw ham, eggs, pork sausage, bacon and salty ham.

3. Variable temperature cold storage area: in the variable temperature area of -2 ~- 14℃, including:

1, water temperature cold storage area (-2 ~-3℃). Foods suitable for this temperature range are: margarine, cheese, condensed milk, fresh cream, butter and so on.

2. Slightly frozen and refrigerated (-3 ~-5℃).

3. Soft freezing (-6 ~-8℃).

4. Moderate freezing (-10 ~- 14℃) can not only keep the nutrition of food from losing, but also keep the taste fresh.

4. Quick-freezing zone: In the freezing temperature zone of-18 ~-2 1℃, foods such as meat, fish and quick-frozen food can be preserved for a longer time, with faster freezing speed and longer freezing duration. Foods suitable for this temperature are: ice cream, frozen fruit, concentrated fruit juice, frozen fish, frozen beef, frozen mutton, frozen pork, frozen chicken and frozen ham.
