Abstract

The invention discloses a pure grape juice beverage and a production method thereof. The production method is characterized by taking fresh grape as raw material and comprising the following steps: processing the raw material, crushing, carrying out enzymolysis, juicing, heating, roughly filtering, carrying out secondary enzymolysis, finely filtering, mixing, sterilizing, filling and sealing, reversing bottle for sterilizing and cooling, putting on labels and spraying codes, and packing to produce a clear type pure grape juice beverage which is delicious and has the characteristics and taste of the grape. The method is capable of carrying out large-scale industrial production; the produced grape beverage is purplish red in color, clear and transparent, and long in quality guarantee period; the grape beverage is stored, circulated and sold at normal temperatures.

Description

Technical field: [0001] The invention relates to a clear grape juice drink and a production method thereof, belonging to the technical field of food processing. Background technique [0002] Grape is the fruit of Vitis vinifera. It is sweet in taste, mild in nature, and slightly sour. It enters the lung, spleen, and kidney meridians; Efficacy of urination; it is mainly used for the treatment of weak qi and blood, cough due to lung deficiency, palpitation and night sweat, rheumatic arthralgia, gonorrhea, edema, etc. The main components of grapes are glucose, fructose, sucrose, xylose, tartaric acid, malic acid, protein, various amino acids, carotene, calcium, potassium, phosphorus, iron and VB1, VB2, VB6, VC, VP, etc. In addition, there is a unique beneficial substance in grapes—resveratrol, which is a strong antioxidant that exists in large quantities in grape juice, which can prevent healthy cells from becoming cancerous, and can inhibit cell proliferation. It also has a ...
