Comprehensive utilization method of plant embryo leaven

Abstract

The invention discloses a comprehensive utilization method of plant embryo leaven. A series of healthy products can be prepared by performing high-pressure steam blasting pretreatment, fermenting, separation, dehydration and the like through taking wheat embryos as raw materials. The comprehensive utilization method comprises the following steps: steam blasting treatment: adding the wheat embryos into a high-pressure instant steam blasting machine, setting the pressure to be 1.0-3.0MPa and holding time to be 30min-120min, and rapidly releasing pressure within 0.0087s after pressure holding; size mixing: adding water and steam-blast materials into a fermentation tank, controlling the solid-liquid ratio to be 1:10 to 1:30, evenly stirring and then increasing temperature and sterilizing, and controlling the temperature to be 120 DEG C to 130 DEG C and time to be 20min-30min; and fermentation: cooling to 25 DEG C to 40 DEG C, adding 1% to 5% of yeast extract under stirring conditions and fermenting for 8h-20h, then adding 3% to 8% of sterilized blueberry powder and 3% to 8% of whole grape powder and fermenting for 2h-4h, and stopping fermenting. By using the method, the grading usage of the raw materials can be realized, different series of functional products can be realized, and the plant embryo leaven can adapt to different crowds aiming at different fiber contents.

Description

technical field [0001] The present invention relates to a method for comprehensive utilization of fermented plant germs, in particular to a series of functional products prepared by fermenting wheat germ, barley germ, corn germ and other biomass with high cellulose content and adding modern healthy elements. Process for the preparation of fermented products. Background technique [0002] Wheat (barley, corn, etc.) germ, as the basis of wheat growth and development, is known as the "source of life" and has a high nutritional value. The protein content in the germ is as high as about 30%, and it contains 8 kinds of amino acids necessary for the human body. In addition to containing 84% unsaturated fatty acids, germ oil also contains 1.38% phospholipids and 4% unsaponifiable matter. Among them, linoleic acid is one of the three essential fatty acids that the human body needs most. It plays an important role in regulating blood pressure, lowering serum cholesterol, and preventi...

[0003] The current application number is 201310174345.4 "A Production Method of Wheat Germ Fermentation Product". Although the wheat germ is fermented, it is separated after fermentation and only the filtrate is dried to prepare the product. The yield is relatively low, and a large amount of high fiber The fermented product has not been reasonably comprehensively utilized, resulting in waste of nutrients and high production costs
