The invention discloses a production process of deacidified low-
sugar apple juice, which comprises the following steps: cleaning apples, squeezing, carrying out enzymolysis, carrying out 
ultrafiltration, adsorbing by using a special resin for juice, and decolorizing and deacidifying by using a special resin for 
fructose to obtain apple 
polysaccharide; meanwhile, carrying out acid 
pickling by usinga decolorized and deacidified 
fructose special resin to extract apple 
polyphenol; and finally, mixing the apple 
fructose, the apple 
polyphenol and 
purified water, sterilizing, and performing sterilefilling to obtain the all-natural deacidified low-
sugar apple juice. The production process is efficient and simple, the content of apple fructose and apple 
polyphenol is increased on the basis of ensuring the taste and color of the product, the purity of the apple fructose is ensured, the loss of nutritional ingredients in apples is avoided, and the apples can be better utilized. The deacidifiedlow-
sugar apple juice does not contain any additive or 
preservative, is green, safe, good in taste, high in 
sweetness, low in 
glycemic index, not prone to causing 
decayed teeth, low in 
calorie and excellent in moisturizing performance, and has the effects of refreshing, protecting the liver, strengthening the body and protecting the 
skin.
