Problems solved by technology

[0003] There are 3 million tons of wheat germ available for development and utilization in my country every year, but the current development and utilization is less than 10,000 tons. Most of the wheat germ is mixed into bran as feed or used for oil extraction, resulting in low-quality utilization of high-quality resources

Embodiment Construction

[0021] The components contained in the wheat germ beverage made in the present embodiment are as follows: vitamin E content 10mg / 100ml, octacosanol content 6mg / 100ml, sucrose content 4% (W / V), milk powder content 2% ( W / V), the content of Tween 80 is 0.2% (V / V), and the rest is enzymatic hydrolyzate of wheat germ protein; the above-mentioned components are homogeneously prepared into wheat germ beverage after fully stirring.

[0022] Such as figure 1 Shown, its preparation method comprises the following steps:

[0023] 1. Extraction of vitamin E crude extract and preparation of defatted wheat germ powder

[0024] The newly separated wheat germ in the wheat flour production process is dried at 70-80°C to inactivate the enzyme activity, and then crushed to about 80 mesh for later use. Use a tray balance to weigh 200g of dried and crushed wheat germ, put it into the extraction kettle of the carbon dioxide supercritical device, raise the temperature to 40-45°C, start the booster...

Abstract

The invention discloses wheat germ drink, which mainly comprises micromolecule peptide prepared by enzymolysis of proteins of wheat germs, vitamin E and octacosanol. The invention further discloses a preparation method of the wheat germ drink. The method comprises the following steps: 1) purifying the proteins of the wheat germs, and performing two-stage enzymolysis for preparing micromolecule peptide solution; 2) adopting supercritical CO2 extraction and molecular distillation technologies for extracting and preparing the vitamin E from the wheat germs; 3) adopting the supercritical CO2 extraction and multiple crystallization technologies for extracting and preparing the octacosanol; and 4) adding Tween 80, and preparing the vitamin E and the octacosanol into emulsion. The main nutritional ingredients of the wheat germs, namely the vitamin E, the octacosanol and the proteins of the wheat germs, are separated and purified, the enzymolysis technology is used for preparing the micromolecule peptide, the vitamin E and the octacosanol are prepared into the emulsion, the three nutritional ingredients are re-combined according to a certain proportion, and auxiliary materials are further matched, thereby preparing the wheat germ drink with anti-fatigue, anti-oxidation, anti-hypertension and other functions.

Description

[technical field] [0001] The invention relates to beverages, in particular to a beverage with wheat germ as raw material and a preparation method thereof. [Background technique] [0002] Wheat germ is a by-product of wheat flour milling, generally accounting for 15-30% of the weight of wheat grains, it is the essence of wheat grains, rich in nutrients, rich in protein, fat, multivitamins, minerals and some trace physiological activities The ingredients are praised by nutritionists as "human's natural nutritional treasure house". The protein content in wheat germ is about 30%. The proportion of amino acids in the protein is reasonable. It contains 8 kinds of amino acids necessary for the human body, especially rich in lysine which is short in general grain protein. It is a high-quality plant protein resource. The fat content in wheat germ is about 10.5%-13.0%, and its main components are unsaturated fatty acid oils such as linoleic acid, oleic acid and linolenic acid. Wheat...
