Description

Composite selenium-rich solid beverage and preparation method thereof Technical Field The invention relates to the technical field of food processing, in particular to a compound selenium-enriched solid beverage and a preparation method thereof. Background Selenium is a trace element necessary for human body, is a core active center of 25 human selenoproteins such as glutathione peroxidase, thioredoxin reductase and the like, and directly participates in key physiological processes such as antioxidant defense, immune cell proliferation differentiation, thyroid hormone metabolism and the like of an organism. If the selenium intake is insufficient for a long time, the immunity of the organism is reduced and the risk of chronic diseases is increased, so that the safe, efficient and compliant selenium supplementing product has great market demands and social values. Currently, two main core pain points exist in the selenium-enriched supplement products disclosed in the market and the prior patent, and the two requirements of technological innovation breakthrough and industrial compound standard landing cannot be met at the same time: First, there is an impending industry core conflict in technical aspects. The existing product is either quick release type, the selenium component is quickly dissolved in stomach, the concentration of blood selenium is suddenly increased and suddenly reduced, the in vivo retention time is short, the bioavailability is low, or the existing product is single slow release type, although the release time is prolonged, the compact embedding structure leads to obvious reduction of the transmembrane absorption efficiency of intestinal epithelial cells on selenium, and the better slow release effect is achieved, the lower absorption efficiency is the irreconcilable contradiction. Meanwhile, the existing product focuses on the selenium supplement itself, does not match with a prebiotic synergistic system aiming at intestinal absorption characteristics of selenium, does not construct an antioxidant-immunity synergistic system, has obvious effect of improving immunity of single selenium supplement, and cannot realize synergistic gain of 1+1> 2. Second, there is a serious risk of food safety compliance at the industrial level. In the prior large number of patent schemes, the problems of over-range use of food additives and nutrition enhancers generally exist, such as selenium yeast only used for milk-containing beverages and ethyl cellulose only used for candy baked foods are used for common solid beverages, and high-purity lentinan nucleoside monomers and the like which are not listed in GB2760 are directly added, so that the scheme cannot be approved by SC production, does not have industrial feasibility and even faces administrative punishment risks. Meanwhile, the existing products mostly adopt high-temperature mixing, hot air drying and other processes, so that the oxidative degradation of heat-sensitive active ingredients such as seleno-amino acid, cordyceps polysaccharide and the like is easy to cause, the storage stability of the products is poor, and the functional activity is obviously lost in the quality guarantee period. Aiming at the pain points of the industry, the intestinal targeting biphase selenium-releasing composite selenium-rich solid beverage is developed, the core contradiction of the slow release-absorption industry is broken through the targeting formula design, the industrialized landing is realized through full-component compliance reconstruction, the active ingredients are reserved to the maximum extent through a mild non-thermal processing technology, and the triple promotion of selenium supplementing efficiency, immune enhancement function and compliance is finally realized. Disclosure of Invention The invention aims to provide a compound selenium-rich solid beverage which breaks through the trade contradiction that slow release and absorption cannot be achieved, has the functions of rapid selenium supplement and long-acting retention and synergistically enhancing immunity, and also provides a preparation method of the solid beverage. In order to achieve the above object, the present invention provides the following technical solutions: The invention provides a compound selenium-rich solid beverage which comprises, by mass, 20-50 parts of selenium-rich black rice, 5-20 parts of a compound biphasic selenium source, 10-30 parts of a compound prebiotic, 1-5 parts of green tea polyphenol, 0.05-1 part of momordica grosvenori glucoside, 0.05-1 part of zinc citrate and 0.05-1 part of shiitake mushroom extract. Preferably, the compound biphasic selenium source comprises a fast-release selenium source and a long-acting selenium source; the mass ratio of the quick release selenium source to the long-acting selenium source is 1:1-3. Preferably, the quick release selenium source is selenium-enriched edible fungus powder; the long-acting selenium source comprises a core mater
