concept

Freeze-dried food for infants and infants refers to the products processed by freeze-drying technology that are suitable for infants and infants to eat. With the characteristics of no loss of nutrition, easy preservation, convenience to eat, safety and health, freeze-dried food is suitable for requirements of nutritional components for infants and infants, mainly including freeze-dried fruit particles and freeze-dried fresh fruit crisp pieces. Like other freeze-dried foods, infant and infant freeze-dried products do not contain oil, additives or preservatives. They are truly natural foods, easily digestible and absorbed, with no loss of nutrients.

Principles and techniques

Freeze-dried food is the abbreviation of vacuum freeze-dried food, also known as FD food. Vacuum freeze drying (FD) technology started in the early 20th century. In the 1940s, FD technology was first tested in the laboratory by Russian scientists and achieved success. After world war ii, FD technology was used in medicine, biology, aerospace and aviation. In the 1960s, the United States used this technology to produce freeze-dried food as space food for astronauts, so freeze-dried food is also known as space food.

FD food is to use sublimation principle to dehydrate and dry the materials containing water by placing them in a vacuum tank after preparing to freeze. It first freezes the water in the food into ice, and then sublimates it to air with high heat, thus dehydrating and drying the food. The dehydrated food could not be kept fresh for a long time due to the release of microorganisms and enzymes through water.

Rise and advantage

Freeze-dried food has quietly emerged in China and is being widely understood and recognized by people. At present, freeze-dried fruit slices and freeze-dried instant soup have not only flown to the first-class cabin and crew table of dozens of flights of 13 domestic airlines, but also are very popular in supermarkets in Beijing and Shanghai and other big cities. With the rapid rise of infant and child industry in recent years, some enterprises focusing on freeze-dried food saw the broad market prospect of infant and child industry and began to test water production and sales of infant and child freeze-dried food. From freeze-dried fruit slices for infants and infants, to freeze-dried colostrum for infants and infants, more and more freeze-dried foods for infants and infants have come into being, and more and more brands for infants and infants have started to focus on freeze-dried foods.

For maternal and child food industry, the advantages of freeze-dried food are natural, nutritious and safe, which exactly meet the industry’s requirements and attention to food safety.

Freeze-dried foods treated with FD technology can achieve a retention rate of more than 96% of their intrinsic nutrients, and the extremely light aromatic oils contained in the food can be retained on the surface of the food without loss. Compared with ordinary food, maternal and child freeze-dried food’s biggest advantage is the ability to keep food original appearance, color, nourishment composition basically remain unchanged, sometimes even make is more taste and aroma of some products, improve the flavor of the food, increase the palatability of food, and do not need to be refrigerated food can be long-term preservation. Aile, an expert in maternal and infant freeze-dried food, believes that with the improvement of the awareness of healthy products in China and the attention of mothers to the healthy growth of children, freeze-dried pregnant and infant auxiliary food will be more and more recognized and loved by consumers.
