Abstract

The invention discloses a production process for a kvass type solanum tuberdsm drink. The process includes: soaking solanum tuberdsm in water for 10-15min and conducting cleaning; slicing and mincing solanum tuberdsm; performing baking at 165-185DEG C for 1-2h; adding water and conducting hydrolysis at 80-85DEG C for 15-25min; adding medium temperature amylase to carry out enzymolysis at 60-70DEG C for 25-35min; adding glucoamylase, adding citric acid to adjust pH to 4.0-4.8, and carrying out enzymolysis at 70-75DEG C for 25-30min; performing standing for 30-40min to obtain a saccharification liquid; boiling the saccharification liquid for 10-20min, adding hops, and further conducting boiling for 3-6min; adding water and conducting filtering to obtain a clear liquid; adding lactic acid bacteria and yeast, and conducting fermentation at 25-30DEG C for 12-48h; carrying out filtering and ultrahigh temperature homeopathic sterilization, thus obtaining the kvass type solanum tuberdsm drink. The process provided by the invention adopts the kvass technology and combines fermentation. The drink is rich in nutrients, is tasty, and has full and mellow flavor, rich taste, and good health care effect.

Description

technical field [0001] The invention relates to the technical field of intensive processing of agricultural products, in particular to a production process of a kvass type purple sweet potato drink. Background technique [0002] Purple potato, scientific name: Solanum tuberdsm, also known as black potato, the potato meat is purple to dark purple. In addition to the nutrients of ordinary sweet potatoes, it is also rich in selenium and anthocyanins. Anthocyanins have preventive and therapeutic effects on more than 100 diseases, and are known as the seventh essential nutrient after water, protein, fat, carbohydrates, and minerals. Anthocyanin is the most direct, most effective and safest free radical scavenger discovered by the scientific community to prevent and treat diseases and maintain human health. Its ability to scavenge free radicals is 20 times that of vitamin C and 50 times that of vitamin E. Anthocyanins in purple sweet potato have antioxidant activity, which can r...
