Freeze Dried Apple Pieces
Apples are rich in nutrients such as folic acid, flavonoids, pectin, vitamins and carbohydrates, and are produced in large quantities in our country. In order to enrich apple processed products, the apple freeze-drying technology is used to set up an apple freeze-drying machine production line for apple freeze-drying processing and production, retaining the rich and natural nutrients of the original apples and enhancing the value.
Apple freeze-drying technology is based on the coexistence or transformation of the three states of water (liquid, solid, and gas) at different temperatures and vacuum, and the use of the sublimation principle to pre-freeze the apples into a solid state, and then freeze the solid ice in a vacuum environment. A processing method for obtaining freeze-dried apple products that retain nutritional components and contain little water by sublimation and removal without liquefaction. Apple freeze-drying technology is a method to keep apples from spoilage. Traditional processing methods include drying, sun drying, spray drying and vacuum drying, which will cause material collapse and deformation, hard texture, Oxidative discoloration, loss and destruction of heat-sensitive substances in apples such as protein, vitamins and trace elements, and apple freeze-drying technology is dry operation under ultra-low temperature and vacuum environment, the growth of microorganisms and the action of enzymes are basically impossible, oxygen extreme The less easily oxidized substances are protected, so the nutrients are fully protected, and at the same time sublimated and dried to leave a porous sponge shape, so the body shape is basically unchanged and the rehydration is good, which has obvious advantages over traditional processing methods.
