Eucommia bark fermented health care vinegar and preparation method thereof

Abstract

The invention discloses eucommia bark fermented health care vinegar and a preparation method thereof. The preparation method comprises the following steps: (1) preparing a basic fermentation solution: crushing ponkan pulp, extracting juice, conducting coarse filtration, conveying the obtained juice into a cloudy juice tank, adding a folium cortex eucommiae extracting solution, regulating a sugar content and conducting pasteurization, so that the basic fermentation solution is prepared; (2) conducting primary fermentation: inoculating the basic solution with an activated wine-activating yeast, and conducting fermentation at 20-28 DEG C for 5-10 days, so that eucommia bark-ponkan fruit wine is prepared, conducting filtration, and conveying the fruit wine into an acetic acid fermentation tank; and (3) conducting secondary fermentation: adding 8-12% of domesticated acetic acid bacterium liquid to the eucommia bark-ponkan fruit wine; and conducting aerating agitation for 2-3 times every day at 26-33 DEG C for 3-4 days, 1min per time, so that the fruit wine gets into full contact with oxygen, and subsequently, the health care vinegar is obtained. According to the health care vinegar and the preparation method thereof disclosed by the invention, by effectively integrating such technologies as vacuum pulsation enhanced mass transfer, biological fermentation, enzymatic hydrolysis and the like, an optimum effect of preparing the eucommia bark fermented health care vinegar from the folium cortex eucommiae and the ponkan juice is achieved; and the health care vinegar is strong in market competitiveness and broad in application prospect.

Description

technical field [0001] The invention relates to a fermented eucommia health vinegar and a preparation method thereof, in particular to a method for preparing fruit vinegar by fermenting eucommia leaf extract and ponkan juice. Background technique [0002] Eucommia ulmoides leaves are the dry leaves of Eucommia ulmoides, which are harvested in summer and autumn when the branches and leaves are lush, and dried in the sun or at low temperature. Modern pharmacological research has proved that Eucommia ulmoides leaves and skin have similar pharmacological effects, and have the functions of nourishing liver and kidney and strengthening bones and muscles. Wait. [0003] Ponkan vinegar is a fermented fruit vinegar made from ponkan juice. Modern medical research shows that: fruit vinegar can promote metabolism, regulate acid-base balance, and eliminate fatigue. Fruit vinegar contains more than ten kinds of organic acids and human body. various amino acids needed. [0004] Using po...
