The invention relates to a preparation process of squeezed apple juice and belongs to the technical field of foods and beverages. A crushing and pulping, and steam enzyme inactivation integrated coupling technology is adopted; after pulping and enzyme inactivation are carried out, ultra-fast cooling can be immediately carried out; vacuum cooling and frozen saline water conducting cooling are coupled; in a whole technological process, technological parameters are strictly controlled and the quality of apples is protected to the greatest extent; the heat acting temperature is reduced and the heat acting time is shortened; the enzyme inactivation effect is extremely good; and original color and luster, flavor and nutrients of the apples are kept. The preparation process can be realized through the following aspects that quality control, crushing and pulping and steam enzyme inactivation on the apples are coupled; and the ultra-fast cooling, superfine crushing, blending and homogenization, sterilization and rapid cooling, and sterile filling are carried out. The squeezed apple juice produced by the preparation process inhibits enzymatic browning to the greatest extent through utilizing a physical method and the original flavor, mouth feel and nutrients of the fresh apples are kept; and pigments, essence, preservatives and the like are not added, so that the high-quality squeezed apple juice can be obtained.
