Preparation method for health-care cordyceps vinegar

Abstract

The invention provides a preparation method for health-care cordyceps vinegar. The method mainly comprises the following steps that nanofiltration is conducted on the upper clear fermentation liquid of cordyceps by a filtration device, and freeze drying is conducted to obtain precipitated powder of the clear fermentation liquid of cordyceps for usage; then, peeled rice is cleaned with water, the water is drained, the rice is placed in a tank, water is added until the water is over the rice, and soaking is conducted for 2-3 days; water draining is conducted, and the rice is steamed at normal pressure; steamed rice falls into a fermentation tank, water, wheat koji and wine yeast are added and mixed evenly, the PH is adjusted to be 4, stirring is conducted, the temperature is kept at 30-32 DEG C, and wine mash is prepared 5-7 days after fermentation is conducted in the tank; mixture liquid formed by fully mixing wheat bran, rice chaff and acetic acid bacterium seed is added into the wine mash, and then the mixture liquid is evenly conveyed into an acetic fermentation tank to be subjected to acetic fermentation; the precipitated powder is added during the fermentation-grain loosening and reflux process, and reflux is continued; then, salt is added and vinegar is prayed in the mixture liquid, and after sterilization, the finished vinegar is poured into a sterilized package bottle to be sealed. The preparation method for the health-care cordyceps vinegar has the advantages that through the adoption of the design, cordyceps polysaccharide and the like in the fermentation liquid are dissolved in the vinegar, so that the vinegar has a health-care function.
