Freeze dried fruit jerky is a fruit jerky made through vacuum freeze drying technology.The reason for freeze-drying technology:Fruits and vegetables provide people with vitamins and other nutrients.In order to extend the shelf life of these foods,methods of drying,drying,pickling,and cooking have been developed to make canned fruits.However,substances such as vitamins have poor high-temperature resistance.Once they encounter high temperatures,they will suffer serious losses.As long as there is a need,there is creation.Therefore,intelligent people have developed low-temperature processing technology-freeze-drying technology.

As the name suggests,vacuum freeze-drying technology involves freezing food above-30 degrees Celsius,then placing it in a vacuum freeze-drying machine,and sublimating it to remove most of the moisture from the food.For example,the dehydration rate of dried fruits can reach over 98%.

Of course,the sublimation temperature is also relatively low,with vacuum and low temperature,which determines that a freeze-drying technology is very vitamin friendly.

Compared with other technologies,freeze-drying technology can reduce the damage to food nutrition,structure,and biochemical effects.The color and shape of freeze-dried food remain almost unchanged,and the disappearance of water not only hinders the survival of microorganisms and prolongs the shelf life of the food,but also greatly reduces weight,making it easier to carry and transport.

Freeze dried food has a loose structure and is prone to absorbing moisture from the air.After absorbing water,it can be restored to its original state.Therefore,it is important to pay attention to the packaged food after freeze-drying,which is generally stored under vacuum or nitrogen filling.If the freeze-dried food you purchase does not have the aforementioned anti-corrosion measures,it will come into contact with oxygen in the air and decay in a relatively short period of time,just like before freeze-drying.Therefore,it is recommended to consume as soon as possible after opening the refrigerator.If you do not want to eat,please remove the air from the refrigerator and seal it.However,as long as it is freeze-dried and stored in nitrogen gas,it can be stored for a long time without opening the seal.Taking dried apples that take a little time in the morning as an example,freeze-dried and nitrogen filled dried apples can have a shelf life of up to 18 months.

In addition,unsealed dried apples(peeled and sliced)are as white as fresh apples,fresh and sweet,and turn yellow after being left in the air for a long time.This indicates that he is really fresh~his nutrition is well preserved.Due to processing technology,freeze-dried mangoes do not contain oil.Freeze dried mangoes are also known as"FD".If you see"VF",you should be careful not to be attracted by its advertising slogan.It is not freeze-dried.This is a low-temperature oil bath.Its full name is vacuum low-temperature oil bath drying,which is different from vacuum freeze-drying technology.

The oil content of vacuum fried fruit and vegetable slices exceeds 10%and requires preservation with preservatives.In contrast,freeze-dried mangoes and vegetables are healthier because they are not fried and have higher nutrition.
