Fermented fruit and vegetable juice containing rich black corn anthocyanin as well as preparation method and device thereof

Abstract

The invention discloses fermented fruit and vegetable juice containing rich black corn anthocyanin as well as a preparation method and device thereof. The fermented fruit and vegetable juice is prepared from the following raw materials: fruit and vegetable juice, black corn anthocyanin extract, a sweetener, a stabilizing agent, a compound fermentation agent and distilled water; the preparation method comprises the following steps: S1: chopping fruits and vegetables, and mixing a complex enzyme, fruit and vegetable blocks and de-ionized water; pulping and filtering to obtain raw fruit and vegetable juice; S2: decompressing and concentrating the raw fruit and vegetable juice; adding a compound fermentation agent and carrying out four phases of fermented to obtain fermented fruit and vegetable juice; S3: adding the black corn anthocyanin into the fermented fruit and vegetable juice; carrying out reverse osmosis dehydration treatment and high-pressure homogenization treatment to obtain homogenized fruit and vegetable juice; S4: sterilely filling the homogenized fruit and vegetable juice to obtain the fermented fruit and vegetable juice containing rich black corn anthocyanin. Totally, the prepared fermented fruit and vegetable juice has high black corn anthocyanin content; the loss of nutrient components of the fruit and vegetable juice is less and the nutrient value is high.

Description

technical field [0001] The invention relates to the technical field of beverage fermentation, in particular to a fermented fruit and vegetable juice rich in black corn anthocyanins and a preparation method and device thereof. Background technique [0002] Black corn is a special type of corn. Melanin is deposited in different degrees in the cuticle of black corn grains, so the grains are black and shiny, which is called black corn. The nutritional value of black corn is very high, and its grains are rich in water-soluble melanin and various It is an essential trace element, plant protein and various amino acids, and its nutritional value is higher than that of other cereal crops. At the same time, black corn contains a huge amount of anthocyanins, and one black corn is equivalent to 16 content of blueberries, which is rare among cereal crops. [0003] With the continuous improvement of people's quality of life, people pay more and more attention to the nutritional value of ...

AI Technical Summary

Problems solved by technology

[0005] In the actual investigation, we found that the preparation of fruit and vegetable juices related to black corn anthocyanins is rarely involved in the prior art, and there are still some deficiencies in the content and purity of the extraction of anthocyanins from black corn. There are still some problems in the preparation process, such as the fermentation effect is still unstable, the effect is low, etc. Therefore, a new type of fermented fruit and vegetable juice rich in black corn anthocyanins, a method for extracting black corn anthocyanins, Preparation method of fermented fruit and vegetable juice to solve these technical problems
