What is freeze-dried fruit?
Freeze-dried dried fruit is dried fruit made by vacuum freeze-drying technology.
Reasons for freeze-drying technology:
Fruits and vegetables provide people with nutrients such as vitamins. In order to prolong the shelf life of these foods, people have developed, sun-dried, dried, pickled, and cooked and made into canned fruits, but things like vitamins and the ability to withstand high temperatures is really poor, once it encounters high temperatures, it will suffer serious losses.
There is a need to create, so people full of wisdom have developed low-temperature processing technology ~ and freeze-drying technology.
Briefly introduce this vacuum freeze-drying technology：
As the name suggests, the vacuum freeze drying technology is to freeze the food at minus 30 degrees, then put it into a vacuum freeze dryer, and then sublime and dehydrate it to remove most of the water from the food, like the VFD dried fruit. The rate can reach more than 98%.
The sublimation temperature is relatively low, vacuum + low temperature, which determines that the freeze-drying technology is very friendly to vitamins.
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 are almost unchanged, and the disappearance of water not only makes it difficult for microorganisms to survive on the food, but also prolongs the shelf life of the food, and also greatly reduces its weight, making it more convenient to carry and transport.
Commonly used in pharmaceutical products, freeze-dried fruits, vegetables, freeze-dried yogurt, freeze-dried porridge, and freeze-dried vegetable soup.
Freeze-dried food is loose in structure, easy to absorb moisture in the air, and can be restored to its original state after absorbing water, so after freeze-drying, pay attention to the packaging, usually in vacuum or nitrogen storage, if the freeze-dried food you buy does not have the above preservatives It will come into contact with the oxygen in the air, and it will rot in a relatively short period of time as before it was freeze-dried. Therefore, it is recommended to eat it as soon as possible after opening it.
However, as long as it is freeze-dried and stored with nitrogen, it can be stored for a long time without opening the package. Take VFD Dried Fruit as an example, the shelf life of dried apples filled with nitrogen after freeze-drying can be as long as 18 months.
If we purchase dried apples after opening (peeled and cut into slices) are the same white color as fresh apples, have the same fresh and sweet taste, and turn yellow after being left in the air for a long time. It shows that it is really fresh~ The nutrition preservation is also very good.
Because of the processing technology, freeze-dried fruit will not involve oil. By the way, freeze-dried is also called “FD”. If you see “VF”, be careful not to be induced by its advertising words, it is not freeze-dried, it is a low-temperature oil bath, the 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 chips is more than 10%, which needs to be preserved by adding preservatives. Relatively speaking, freeze-dried fruit and vegetable chips are healthier because they are not fried and have higher nutrition.
Many ingredients of freeze-dried fruit only have fresh fruit, and some of them will add some sugar. For example, strawberries need to add sugar to neutralize acidity.
Freeze-dried fruit is low-fat, dehydrated, and becomes very strong, and the relative calories are not high, that is, the freeze-dried fruit sold by some merchants is white on the outside, and it is called “collagen”. It is to brush a layer of chocolate on the outside so that the taste will be better, but the heat will be higher.
After freeze-drying, it needs to be anti-corrosion and anti-oxidation, otherwise, it will be like a bite of an apple, which will become oxidized and discolored, and will also absorb moisture in the air.
Many people are worried that some delicious food is not good for their health.
VFD has been focusing on solving this problem for many years. We use the creation of natural functional food, targeted nutrition technology, and freeze-drying technology to preserve the naturalness and functionality of the ingredients to the greatest extent and great progress has been made in biological enzyme fermentation, probiotic activity, protein activity, extracts, etc.
In particular, a variety of active nutrients and food are perfectly combined to create high-quality natural functional foods that are nutritious, beneficial to health, delicious, and easy to use, so that we can enjoy natural deliciousness and take care of our health. Everyone who cares about the health and likes food Everyone deserves it.
