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.
