Embodiment 1

[0022] The preparation method of purple potato health drink comprises the following steps:

[0023] 1) Raw material pretreatment: select fresh purple potatoes without pests and damage, wash them, peel them, slice them, and blanch the cut potato chips in hot water at 100°C for 1 minute, then put them in at a concentration of 0.8 % salt solution for 6 minutes, then washed with clear water, drained, added water 1.5 times its weight for beating to obtain purple potato slurry;

[0024] 2) Enzymatic hydrolysis: Add amylase and pectinase to the purple potato slurry in step 1), stir evenly and enzymolyze at 45°C for 5 hours, the contents of the added amylase and pectinase are respectively 0.05%, 0.03% by weight;

[0025] 3) Enzyme inactivation and centrifugation: inactivate the enzymatically hydrolyzed purple potato slurry in a water bath at 90°C for 10 minutes, then centrifuge at 4500 r / min for 25 minutes, filter, and take the supernatant to obtain purple potato juice;

Abstract

The invention discloses a preparation method of a purple sweet potato health drink. The preparation method comprises the following steps of: with purple sweet potatoes as a raw material, carrying out pretreatments, such as selecting, cleaning, peeling, slicing and pulping to obtain purple sweet potato pulp, carrying out enzymolysis, enzyme deactivation and centrifugation on the pulp to obtain purple sweet potato juice, then adding auxiliary materials, such as a sweetening agent, citric acid and a stabilizing agent to blend, filling and sterilizing to obtain the purple sweet potato health drink. The purple sweet potato health drink is palatable in scour and sweet mouthfeel, unique in flavor and rich in nutritions and has the health care functions of resisting oxidative activity and cancer, delaying senescence, strengthening physique, improving eyesight and the like. The purple sweet potato health drink does not contain harmful additives, is an environment-friendly health drink suitable for people of all ages, is wide in consumer group and has a wide market prospect.

Description

technical field [0001] The invention belongs to the field of beverage processing, and in particular relates to a preparation method of a purple potato health drink. Background technique [0002] Purple potato is introduced from South America in recent years. It is a new variety of colorful potato that integrates food, nutrition, health care and ornamental. Its shape is oblong, with small bud eyes. great taste. In addition to the various nutrients of ordinary potatoes, purple potatoes are also rich in anthocyanins, which have multiple health functions for the human body. Anthocyanins have the functions of anti-oxidation, anti-aging, scavenging free radicals, enhancing physical fitness, improving fat content in serum and liver, anti-mutation and anti-tumor, and preventing peroxidation in organisms. [0003] At present, the research on purple potato is mostly focused on the cultivation technology, anthocyanin extraction and antioxidant properties of purple potato, but less on...
