Abstract

The invention discloses a preparation technique that produces vinegar with the fermenting raw materials of blackfungus and brown rice, provides a submerged liquid fermenting technique of the blackfungus and brown rice vinegar with bioactive ingredients of the blackfungus and the brown rice, and obtains the vinegar product with sweet and sour tastes, abundant nutrition and health care value through a method that manually controls technical parameters relevant to the processes of saccharification, alcoholic fermentation, acetic acid fermentation and the like.

Description

A kind of production technique of black fungus brown rice vinegar

Technical field

The present invention relates to a kind of have functional vinegar product and deep liquid fermentation process thereof.

Background technology

Vinegar is known by common people already with the effect of its distinctive nutritive value and illness prevention and fitness, is at home and abroad quite paid attention to and welcomes.

Substitute grain to pester and brewage mushroom vinegar, not only all better on nutrition, local flavor, mouthfeel than traditional vinegar, and nutritive ingredient such as the mushroom VITAMIN, mineral substance, amino acid that are rich in and health-care components be retained in brewageing down, improved the nourishing function of mushroom vinegar greatly.Can satisfy different levels, different consumer demand, substituting with rice, glutinous rice starch is traditional vinegar of main raw material.The kind of the mushroom vinegar that has gone on the market at present is a report not almost to the research of black fungus vinegar especially seldom.

Black fungus is the edible treasure of tradition that people like, not only fine and tender taste is good to eat, and is nutritious, and has very high pharmaceutical use.It has beneficial gas brute force, invigorate blood circulation, pain relieving, wash effects such as stomach and intestine clearly.Modern medicine study proof black fungus has great effect to preventing human cardiovascular and cerebrovascular and tumour class disease.In addition, cause the reason of aging, cancer and disease such as cardiovascular relevant, generally acknowledged by medical circle with oxidative stress damage and Radical Metabolism imbalance.Thereby the development and utilization with the active natural resource of strong anti-oxidation has become the trend of biology, medical science and food scientific research.According to the study, black fungus has the activity of eliminating hydroxy radical qiao, and its elimination factor can reach about 40%.

Changbaishan area has abundant black fungus resource, but processing mode is very single, does not almost have special processing mode except that the black fungus dry plate.In order to adapt to the upsurge of " function vinegar ", the present invention is main raw material with the black fungus, and brown rice has been made the black fungus brown rice vinegar for the subsidy raw material by liquid submerged fermentation.The invention of black rice ear brown rice vinegar will bring completely new concept for the vinegar industry, and improve the economic benefit at black fungus plantation family, can drive local economic development simultaneously.

Summary of the invention

The purpose of this invention is to provide a kind of deep liquid fermentation process with black fungus brown rice vinegar of black fungus, brown rice bioactive ingredients.

The present invention utilizes northeast to produce dried black fungus to be main raw material, brown rice utilizes microbial liquid submerged fermentation technology for the subsidy raw material, and wherein bacterial classification is dry yeast and acetic bacteria, the biologically active substance that has kept black fungus and brown rice to greatest extent, this production technique may further comprise the steps:

1 material choice: select northeast no insect pest, complete to produce dried black fungus; Full grains, the brown rice that glossiness is good;

2 raw materials are handled: black fungus is cleaned, soaks to abundant suction, pulverizing, carries 1-3 hour in 70-90 ℃ of hot dipping;

3 saccharification: brown rice cleans, pulverizes, sieves, and boiling adds the water of suitable multiple to thoroughly well cooked but not mushy, and with edible acid for adjusting pH value to 4.0～5.0, adds saccharifying enzyme saccharification certain hour, makes brown rice liquid pol reach 15-25 ° of BX;

4 zymamsiss: above-mentioned black fungus treatment solution is mixed with brown rice saccharification liquid, make initial pol reach 10-20 ° of BX, and carry out pasteurization, add high activity dried yeast actication of culture liquid, 25-34 ℃ of fermentation 35-45 hour, when reaching 6-9% (V/V), ethanol content stops fermentation;

5 acetic fermentations: the acetic bacteria seed liquid that adds volume percent in the fermented liquid after zymamsis and be 5-10% (is inoculated in liquid seed culture medium with the acetic bacteria slant strains, 30-33 ℃ of shaking speed 150-200rpm, cultivated 20-25 hour), 32-34 ℃ of fermentation 4-7 days, be 3-5% (with acetometer) until total acid content

In time, stop to ferment, and obtains the former vinegar of black fungus brown rice.

6 sterilizations: the former vinegar that fermentation is obtained carries out pasteurization.

7 centrifugings: the former vinegar after will sterilizing centrifugal 15 minutes in 4000 commentaries on classics/min obtains the black fungus brown rice vinegar of clear.

Unique function of the present invention is to have vinegar inherent attribute, has added the bioactive ingredients and the value medical health care of black fungus and brown rice simultaneously.

Embodiment

Select no insect pest, complete dried black fungus, cleaning and dipping is pulverized to fully suction, carries 1-3 hour in 70-90 ℃ of hot dipping; Select full grains, the brown rice that glossiness is good cleans the back and pulverizes with pulverizer, sieves, and boiling is only thoroughly well cooked but not mushy, adds 1-3 times of water and with oxysuccinic acid the pH value is adjusted to 4.0-5.0, adds saccharifying enzyme, and the saccharification certain hour makes brown rice liquid pol reach 15-25 ° of BX.The black fungus treatment solution is mixed with brown rice saccharification liquid, make initial pol reach 10-20 ° of BX, and carry out bus and sterilize, add high activity dried yeast actication of culture liquid, 25-34 ℃ of fermentation 35-45 hour, when reaching 6-9% (V/V), ethanol content stops fermentation, insert 5-10% (v/v) acetic bacteria liquid seeds then, at shaking table frequency 150-200rpm, 32-34 ℃ fermented 4-7 days, when total acid content is 3-5% (with acetometer), stop fermentation, obtain the former vinegar of black fungus brown rice, carry out the bus sterilization.Then at the centrifugal 15min of 4000 commentaries on classics/min, and carry out filtration under diminished pressure, obtain the black fungus brown rice vinegar of clear.
