Description

Water-soluble ginger oleoresin microcapsule and preparation method and application thereof Technical Field The invention relates to the technical field of microencapsulation of natural products, in particular to a water-soluble ginger oleoresin microcapsule, and a preparation method and application thereof. Background Ginger belongs to perennial herbaceous plants of zingiberaceae zingiber, also called rhizoma zingiberis, bai Jiang and the like, and China belongs to the origin of ginger and is also one of main production countries. Ginger is widely distributed in China, and has planting history of over 2000 years. The ginger has rich nutrients, mainly including gingerol, starch, dietary fiber, protein, fat, trace elements, etc. Ginger is widely used as a flavoring in daily life, has the effects of enhancing flavor and flavor, is widely used as a traditional Chinese medicine raw material for treating and preventing some diseases, and has the effects of warming middle-jiao, dispelling cold, restoring yang, dredging collaterals, dispelling dampness and diminishing inflammation as ' Jiang Xingre, pungent flavor, returning to heart, kidney, spleen, stomach and lung channels ' described in Ben Cao gang mu '. It is listed in Shen nong Ben Cao Jing as superior, but it is enough that it is "Ke Shu, ke He, ke Guo, ke Yao and Shen nong Ben Cao Jing". At present, ginger is widely applied in the fields of foods, medicines, health-care foods, cosmetics and the like. Gingerol is a general term of "spicy" components in ginger, which is yellow-yellow brown oily matter, insoluble in water, ethanol, benzene, diethyl ether and other lipophilic solvents, and is a mixture of various substances. The main components of the composition comprise gingerols, shogaols, gingerols, jiang Tonglei, gingerols, neogingerols and the like, and the composition contains flavonoid substances of 3-methoxy-4-hydroxyphenyl. Gingerol is used as a main active substance in ginger, has obvious antioxidation and anti-inflammatory effects, has good effects of invigorating stomach, protecting liver, promoting bile flow, preventing vomiting, resisting gastric ulcer, resisting coagulation, inhibiting tumor and the like, and is widely used in clinical medical treatment and health care food. The ginger oleoresin is a viscous yellow-brown semi-fluid substance which is obtained by taking ginger as a raw material and extracting and concentrating, has strong ginger flavor, mainly comprises ginger essential oil, gingerol and other fat-soluble substances, and is mostly used in seasonings, health-care foods and medicines with antioxidant and anti-inflammatory requirements. With the development of economy, consumer interest in health is raised, and demands for diversification of foods and functionalization are increased, and demands for healthy raw materials of related natural sources are increasing. How to prepare ginger oleoresin microcapsule powder which has high gingerol content, low pungency, good water solubility and stable application in low pH value environment (such as beverage, oral liquid, candy, solid beverage, cold drink, etc.) by adopting food raw materials or raw materials with high safety of natural sources has become a great market demand. Researches on preparing ginger oleoresin microcapsule powder by adopting ginger have related documents and patent reports at present, such as 'influence of spray drying conditions on ginger oleoresin microcapsule' (3 rd phase of food science 2009, university of Yangzhou food science and engineering college), the ginger oleoresin is obtained by adopting ginger as a raw material, ethanol extraction and vacuum drying, and beta-cyclodextrin and tween-80 are adopted as wall materials to prepare ginger oleoresin microcapsule powder by emulsification, homogenization and spray drying, and the influence of different spray drying conditions on ginger oleoresin microcapsule is mainly examined. Chinese patent CN 101473954A discloses a ginger oleoresin microcapsule and a preparation method thereof, chinese patent CN 113424958A discloses a high gingerol content taste-masking microcapsule and a preparation method thereof, chinese patent CN 113952314A discloses a tea polyphenol-gingerol combined particle and a preparation method and application thereof, chinese patent CN 109511983a discloses a ginger oleoresin microcapsule and a preparation method thereof, chinese patent CN 102895189a discloses a gingerol liposome and a preparation method thereof and the like. Although the technology can improve the dissolution effect of the ginger oleoresin to a certain extent, a large amount of chemical synthesis surfactants such as tween, monoglyceride, sucrose ester, polyethylene glycol and the like are used in the preparation process, uncertainty of edible safety exists, and the problems of low content of gingerol, heavy pungency, poor water solubility, low stability in low pH value solution and the like exist in the product, so that the requir
