Embodiment 1

[0020] A preparation process of crystal grape juice, specifically comprising the following steps:

[0021] 1) Choose healthy and mature crystal grapes with a sugar content of 120g / L and a total acid content of 5.8g / L;

[0022] 2) Prepare a stainless steel tank with a manhole, and fill the bottom of the stainless steel tank with CO2 gas to ensure that the grape skins and juice are in direct contact with the CO2 gas;

[0023] 3) the crystal grapes prepared in step 1) are destemmed and broken, then packed into the rust-free steel tank prepared in step 2), and SO2 and pectinase are added alternately in the process of destemming, so that the final concentration of SO2 is 50mg / L, the concentration of pectinase is 20mg / L;

[0024] 4) After the crystal grapes are packed in cans, CO2 gas is added to the surface of the grapes to ensure that the surface of the grapes is protected by a 10cm-thick CO2 gas layer;

Abstract

The invention relates to a process for preparing a pure crystal grape juice. Immersion before peel-juice separation is adopted, CO2 protection is adopted during immersion to prevent the juice from being oxidized, and aroma-adding, flavoring and thickening food additives are not added.
