Analytic alimental is safe “ temperature “
The temperature of food is different, taste flavour is big also different. Every kinds of food has a relative safety “ temperature “ , first-rate nutrition can be saved below this temperature, let you gain first-rate taste experience in the instant of edible. Food is mixed in the deposit when saving, have one each oneself most the temperature that suit, below this temperature, alimental storage life is long, retain at the same time first-rate nutrition and mouthfeel.
Quick frozen food is in – 25 ℃ ~ – between 18 ℃ , the character of quick frozen food will be stabler, if prep above this temperature, the expiration period can shorten accordingly, mouthfeel also can produce change. If the freezer short of in the home – the word of 18 ℃ , after quick frozen food unseals, had better eat as soon as possible, allow easy metamorphism otherwise.
Optimal safe temperature is fish of fresh fish and shellfish as food – 3 ℃ , here the fish below temperature deteriorates not easily, can assure its delicacy flavour, but want as soon as possible edible. What need reminds is, the fish in freezer cannot be deposited too long, the cold storage temperature of family expenses freezer is commonly – 15 ℃ , optimal also can achieve only – 20 ℃ . And aquatic product, especially fish, in store up temperature is achieved – when 30 ℃ are the following, piscine body organization can produce dehydration or other change, be like crucian carp fish, refrigerate for long, appear easily piscine body acid is defeated, the flesh produces change character, cannot edible.
The flesh kind the flesh kind, be like pork, beef, should maintain presence – in the environment of 18 ℃ , such but the integrality that better land maintains cellular wall, be helpful for what water divides maintaining. If be in – the cold storage below condition of ℃ of 2 ℃ ~5, the flesh kind can save a week at most.
Vegetable green vegetable should be in microtherm (not under 0 ℃ ) the environment is saved, if temperature exceeds 40 ℃ , what its contain chlorophyll enzymatic meeting parts chlorophyll and protein and be lost, be like temperature under 0 ℃ , because of,chlorophyll is met again refrigerant and destroy. Chinese cabbage, celery, onion, carrot deposit temperature to be 0 ℃ left and right sides aptly; The optimal temperature that deposits a potato is ℃ of 2 ℃ ~4, temperature crosses tall potato to be able to sprout, affect edible thereby; Cucumber, aubergine, tomato deposit temperature to be ℃ of 7.2 ℃ ~10 aptly between, if temperature is too low,can lose little taste, a serious meeting is cankered; Pumpkin is deposited in 10 ℃ above aptly; Deposit pachyrhizus (yam) optimal temperature is 15 ℃ above, temperature is low, with respect to meeting deadlocked heart cannot edible.
The temperature of dish cold dish is when 4 ℃ are the following, can present optimal gust; And hot food needs to maintain control in 60 ℃ , taste already goluptious won‘t make nutrient composition prediction of a person‘s luck in a given year overmuch again. Additional, if the condition allows, can put dish freezer to refrigerate 3 minutes reoccupy Lai Chengliang dish, or put dish oven to heat 4 minutes reoccupy will fill hot food, can assure the optimal mouthfeel of dish so. Such commonly doing of the large kitchen of the hotel.
The temperature of fruit banana the crown of the year is 30 ℃ about, need to drop temperature 13 ℃ to control when save; Of orange save temperature to be ℃ of 4 ℃ ~5; Storage temperature of the apple is – ℃ of 1 ℃ ~4; Mango is ℃ of 10 ℃ ~13; Papaya is 7 ℃ ; Litchi is ℃ of 7 ℃ ~10, litchi is so unsuited put freezer to save.
