Why are freeze-dried fruit snacks suitable for children?
materials are frozen and then placed in a vacuum environment to allow ice to directly sublime and remove moisture. It is known as the "fourth drying technology". Vacuum freeze-drying is a drying technique that uses the principle of sublimation to dehydrate materials. After rapid freezing, the materials are heated in a vacuum (below the triple point pressure of water) and then sublimated under vacuum to achieve the drying purpose. Freeze-dried fruit snacks are favored for their convenience and natural labels. This technology is widely used in various food fields and has the following advantages. Nutrient retention: The freeze-drying process is carried out at low temperatures, avoiding the damage to heat-sensitive nutrients such as vitamins and proteins caused by high temperatures. Due to rapid freezing, the moisture in the materials changes from liquid to solid ice crystals, fixing the cell structure. During the subsequent sublimation drying, the ice crystals do not undergo liquid phase before vaporization, so the shape remains basically unchanged and the color is not easily changed. Long shelf life: Freeze-dried products have extremely low moisture content and low water activity, making it difficult for microorganisms to survive. They can be stored at room temperature for a long time without the need for preservatives. Good taste: The interior of freeze-dried products is honeycomb-like micropores, and after rehydration, the taste and shape are close to the fresh state, with less flavor loss. Convenience: Freeze-dried products rehydrate quickly, can be soaked immediately when eating, saving time; they are lightweight and convenient to carry and transport. Nutritional value and convenience: Freeze-dried fruits processed by this technology can retain vitamins and minerals in fruits, remove most of the water, making the product more portable and having a longer shelf life. Compared to traditional preserves or dried fruits, freeze-dried fruits have lower sugar content and are more suitable as children's daily snacks. For example, Mimosa Yogurt-flavored Freeze-Dried Fruit and Little Deer Blue Blue Freeze-Dried Fruit Dried are loved by parents and children, and some products are designed with individual small bags, making them convenient to carry and consume. Freeze-dried fruits are suitable for children of all ages. For infants in the initial stage of complementary feeding, the soluble beans can be soaked in warm water to soften before feeding; for preschool children, they can be directly enjoyed as daily snacks. However, it should be noted that although freeze-dried fruits are beneficial to health, excessive intake should be avoided to avoid affecting the appetite for regular meals. Although freeze-dried fruit snacks are considered healthy snacks, the fact is that freeze-drying only removes water, and the sugar in the fruit is concentrated like "sugar cubes". If children do not rinse their mouths after eating, the sugar may corrode their teeth. In conclusion, freeze-dried fruits without added sugar is a good thing and is relatively healthy as a snack. The main problem is that it is relatively expensive. Whether to choose it depends on whether you can consume enough fresh fruits and whether it is cost-effective.
