Abstract

The invention provides a natural clear purple yam beverage and a sweet clear purple yam beverage, and production methods thereof. The production method of the natural clear purple yam beverage comprises the following steps: blanching color protection, beating refinement, enzymatic hydrolysis clarification, pH adjustment, filling, and sterilizing. Ingredients of the sweet clear purple yam beverage comprise, by mass, 92-98 parts of a purple yam enzymatic hydrolysis liquid, 1-4 parts of edible sugar, 1-3 parts of trehalose, 0.03-0.08 parts of edible salt, 0.1-0.9 parts of a concentrated snow pear juice and 0.02-0.04 parts of citric acid. The production method of the sweet beverage mainly comprises blending, filling and sterilizing steps. The two clear purple yam beverages have the advantages of pretty color, high transparency, refreshing mouthfeel, strong thirst quenching effect, richness in anthocyanidins, and no artificial pigments, essences or antiseptics.

Description

technical field [0001] The invention belongs to the field of food processing, in particular to original flavor and sweet clarified purple yam beverage and a preparation method thereof. Background technique [0002] Purple yam, also known as "purple ginseng", contains nutrients such as protein, carbohydrates, vitamins and minerals, as well as functional components such as anthocyanins, polysaccharides, phenolic acids, and saponins. Protect the liver, lower blood sugar, lower blood pressure and other functions. [0003] At present, there are some reports on the production technology of purple yam beverage. CN105054191A discloses a purple yam drink and a preparation method thereof. The drink uses fresh purple yam as a raw material, and sequentially performs pretreatment, color protection, beating, ultrasonic-assisted extraction of anthocyanins, autoclaving and static ultra-high pressure treatment to prepare resistant Starch, deployment, nano-homogenization, filling and high-p...
