Method for processing sweet potato beverage

Abstract

The invention discloses a making method for sweet potato beverage, which is characterized in that: the making method comprises the following steps: 1) rinsing: fresh sweet potatoes are manually or mechanically rinsed, to remove mud, sand and impurity; 2) crushing and grinding juice: the cleaned fresh sweet potatoes are grinded until the grains are less than 1000 micron through a colloid mill or apulping machine, obtaining sweet potato juice. Preservative, sweetener, acidity agent, stabilizing agent, essence, vitamin or one, two or more of the minerals can also be added into the sweet potato juice. The making method has the advantage of simple technology, low production cost, good product quality, high nutritional value, easy absorption and utilization for human body, ability of liquid, solid, grain, capsule, buccal tablet or tablets product forms; and the products made by the method has the advantages that: the dietary fiber, vitamin, protein, polysaccharide, anthocyanin and other compositions of the material are remained, nutritional ingredient of sweet potatoes and active components which can improve humane immunocompetence are remained to the utmost extent, and is an excellentgreen natural health beverage.

Description

technical field [0001] The invention relates to a preparation method of a non-alcoholic beverage, in particular to a processing method of a sweet potato beverage. It is suitable for producing a series of beverage products such as liquid, solid, granule, capsule, lozenge or tablet of sweet potato or similar raw materials. Background technique [0002] In the prior art, the processing and production of sweet potato drinks generally adopts high energy consumption and complicated deep freezing technology, or adopts ultraviolet light and ozone sterilization technology, which is not conducive to large-scale production and is not conducive to effectively retaining the active substances in sweet potatoes and nutritional content. Chinese patent application number 00113012.9 discloses a "fresh potato juice drink and its production method". -0%; the production method is to prepare fresh potato juice obtained by extruding and filtering and water, and then sterilize and fill with ultra...

AI Technical Summary

Problems solved by technology

This patent application has the following defects and deficiencies: (1) Nutrients lose a lot in the product: protein, polysaccharides, vitamins, and anthocyanins in the raw materials lose a lot in production and processing, and there is no dietary fiber in the product; Potatoes are squeezed, the juice is not fully extracted, the potato residues are not utilized, the waste is large, and the utilization is small; (3) the use of ultraviolet light and ozone sterilization will denature and inactivate the active protein and active polysaccharides of sweet potatoes, and the loss of anthocyanins will fade. The structure is destroyed, the physiological activity is lost, and the practicability is poor
