Fermented walnut kernel milk drink produced by using processed by-product of walnut oil

Abstract

The present invention discloses fermented walnut kernel milk drink produced by using a processed by-product of walnut oil. A preparation comprises the following steps: walnut oil is ground, soaked andseparated to obtain emulsified oil and an emulsion; the emulsified oil is subjected to demulsification and refining to obtain refined walnut oil; the emulsion is filtered and homogenized; 5-50 U/g ofcellulase and 10-20 U/g of protease are added to a homogenate solution to conduct enzyme digestion for 1-4 hours; 50-90 g/L of sucrose and 10-30 g/L of glucose are added in an enzymatic solution to be stirred for 10-20 min; the stirred materials are sterilized at 90-95 DEG C for 5 min; the sterilized materials are cooled to 42-45 DEG C; lactobacillus plantarum and lactobacillus helveticus in a ratio of 0.1:2 are added in a cooling solution to be subjected to a constant-temperature fermentation for 8-12 hours; fermented liquid is homogenized; a previously dissolved pectin solution is added; the materials are stirred and mixed for 30-50 min; the mixture is pasteurized for 15 min; the pasteurized mixture is cooled to 25-40 DEG C; and the cooled mixture is subjected to aseptic filling. The fermented walnut kernel milk drink is refreshing in taste, moderate in proportions of fat and proteins and easy for digestion and absorption.

Description

technical field [0001] The invention relates to the field of food and beverage processing, in particular to a walnut milk beverage with high protein and low fat, which is produced by fermenting the by-products in the walnut oil-water generation process. Background technique [0002] In recent years, under the environment of environmental protection, sustainability and animal welfare, along with the development of nutrition and health trends such as cleanliness, sugar reduction and high protein, plant protein beverages have received widespread attention. However, with the rapid development in recent years, the homogenization of protein drinks has become serious and the taste is single, but plant protein is not equal to high-quality protein. Generally speaking, the efficiency of plant protein to supplement protein is not as high as that of animal protein, and plant protein drinks are not as smooth and palatable as animal protein drinks such as milk; the main reason is that pla...
