Developed countries can reach 20% ~ 60%) so deep processing capacity and level need to be improved. The crisp chips of various fruits and vegetables produced by vacuum frying and dehydration make the fruits and vegetables dehydrated at a relatively low temperature, which ensures that the nutritional components of the food are not damaged by high temperature, and the products better preserve the color, taste, shape and nature of the fruits and vegetables, and have a crispy taste.

Vacuum freeze-drying technology and freeze-drying products

Vacuum freeze-drying technology is a drying technology that freezes the dried substance into a solid state at a low temperature (-50 ~10℃), and sublimates the moisture directly into a gaseous state without going through the liquid state under the vacuum condition, and finally dehydrates the material. Vacuum freeze-drying process, because of the vacuum state, does not cause damage to the antioxidant components of the fruit. The low temperature has a good protective effect on the original nutrients of the material, and the shape of the material will not be damaged. In particular, dried fruit and vegetable products obtained in this way have very good rehydration and retain the original flavor of food.
