Preparation method of ocean agar oligosaccharide yellow rice wine with health care function

Abstract

The invention discloses a preparation method of ocean agar oligosaccharide yellow rice wine with a health care function. The preparation method comprises the following steps of adding citric acid in an agar turbid liquid firstly, putting a mixture in a water bath boiler or a sterilization boiler at 70-121 DEG C, degrading agar, then performing cooling to a room temperature, adding calcium carbonate powder or calcium hydroxide powder for reaction, performing centrifugation on a reaction liquid to separate a supernatant and precipitates after reaction is finished, and adding a yellow rice wine brewing raw material into the supernatant for yellow rice wine fermentation production. For the yellow rice wine preparation method provided by the invention, through directional controllable degradation and microbial fermentation transformation of organic acids, yellow rice wines containing different polymerization degrees of agar oligosaccharide can be obtained, so that the yellow rice wine has the health care function activities of loosening the bowel to relieve constipation, regulating intestinal flora, alleviating inflammation and the like, and the nutrition and health care value of the yellow rice wine is increased.

Description

technical field [0001] The invention belongs to the technical field of production of alcoholic beverages, and in particular relates to a preparation method of marine agar oligosaccharide rice wine with health care function. Background technique [0002] Rice wine is a kind of brewed wine with a long history in my country. It is also called the world's three ancient wines together with beer and wine. Yellow rice wine is a traditional good product for health care. It is not only rich in nutrition, but also has physiological effects such as anti-oxidation, anti-aging, lowering blood pressure, lowering cholesterol and immune regulation. With the improvement of people's living standards and the continuous enhancement of health awareness, rice wine with nutrition, health and health care characteristics has been recognized by more and more consumers. At the same time, consumers' demand for nutrition and health care of rice wine is also constantly changing and improving. Therefore,...

Problems solved by technology

Among them, the conditions of redox degradation method are relatively severe, and by-products are easily produced, and the color of the degradation product is darkened, and serious oxidation reactions occur; the enzymatic hydrolysis method uses the agarase that can degrade agar to carry out enzymatic degradation of agar, and the reaction process is relatively simple. Mild, but requires the preparation of agarase, which greatly increases the processing cost; the acid hydrolysis method has a rapid reaction process, but most studies use inorganic strong acids such as hydrochloric acid and sulfuric acid, the reaction process is relatively violent, and by-products are easily produced, which has potential food safety hazards , after the reaction, it is necessary to use ion exchange chromatography or alcohol precipitation method for desalination. The cost of the desalination process is high, and there are problems such as subsequent treatment of inorganic salts, and there is also a certain pollution threat to the environment.
