Abstract

The invention provides high-color-number potato condensed juice and a preparation method. According to the high-color-number potato condensed juice, colored potatoes are used as raw materials, and through treatment of cleaning, peeling, mashing, enzymolysis and yeast fermentation treatment, condensed juice of which the soluble solids are 63-65Brix, and the color number E is greater than or equal to 4.0 is obtained. The high-color-number potato condensed juice has the beneficial effects that microzymes are used for fermentation, so that the color number of the condensed juice is increased, theanthocyan stability in the condensed juice is increased, and further, the color number of the potato condensed juice and the color shade of products are guaranteed.

Description

Technical field: [0001] The invention relates to the technical field of deep processing of fruits and vegetables, in particular to a concentrated potato juice with high color value and a preparation method thereof. Background technique: [0002] Potatoes are currently positioned as the fourth staple food in China after rice, wheat, and corn. They are very important food resources. At present, the main products of domestic potato processing are potato snowflake powder and potato starch. Potatoes are the "king of nutrition" in food. reputation. Potatoes also contain food rich in protein, B vitamins, vitamin C and dietary fiber except containing a large amount of starch. In addition, colored potatoes are rich in anthocyanins on the basis of ordinary potatoes, and anthocyanins are a class that is widely present in Water-soluble pigments in plants belong to flavonoid compounds. Like other natural pigments, anthocyanins are non-toxic and have no side effects, high safety perform...
