The solid beverage has the special fruit fragrance of green plums and cherries, has good taste, moderate sweet and sour taste, loose shape and no agglomeration, can be quickly dispersed and dissolved by warm water, has no layering phenomenon, is rich in nutrition and is convenient to drink.
The green plum can improve the activity of human pepsin, promote the small intestine to move and play a role in promoting digestion; has the comprehensive effects of promoting the production of body fluid to quench thirst, stimulating the appetite and relieving depression, invigorating stomach and helping digestion, eliminating fatigue, regulating the balance of body fluid, delaying senility and the like.
The acerola cherry powder is rich in vitamin C, trace elements and the like, can supplement the vitamin C required by a human body in time, enhances the killing power of leucocytes, and has obvious effect on preventing diseases such as cold, fever, septicemia and the like.
The whey protein powder contains all essential amino acids required by a human body, and the amino acid composition pattern of the whey protein powder is almost consistent with that of the amino acid composition pattern in skeletal muscle, so that the whey protein powder is very easy to be absorbed by the human body; it is easy to digest, and has high protein efficiency and utilization rate.
Glutamine is rich in organism cells, is a special nutrient substance of gastrointestinal tract mucous membrane cells, can be supplemented in time to obviously increase the surface area of transplanted small intestine villi and maintain the integrity of the intestinal tract shape and structure.
The dietary fiber probiotic composition is used in a matching way, so that the probiotic flora in the intestinal tract can be kept balanced, a natural biological barrier is formed in the intestinal tract, translocation of pathogenic bacteria is reduced, the pH value of the intestinal tract is adjusted, and the formation of endotoxin is reduced. The dietary fiber promotes the quantity of probiotics and improves the colonization of the probiotics at the same time, and has the capacity of relaxing bowel.
The inulin has strong hygroscopicity, can delay water evaporation, prevent flavor deterioration, prolong shelf life, has certain health promotion effect, can promote reproduction of probiotics such as Bacillus bifidus in intestinal tract, prevent intestinal infection, promote mineral absorption, and prevent and treat constipation; meanwhile, the blood sugar fluctuation is avoided, the blood sugar level is controlled, and the harm of cardiovascular diseases is reduced.
Sorbitol is used as a nutritional sweetener, and has effects of preventing constipation, maintaining sweet and sour balance, and keeping fragrance. It does not react with amino acid when heated, and can prevent the denaturation of nutrients such as carotenoid and protein, and the crystallization of sugar and salt.
The maltodextrin is used as an emulsification stabilizer, and the tricalcium phosphate is used as an anticaking agent, and the maltodextrin and the tricalcium phosphate are used in a matching way, so that the brewing property of the solid beverage can be effectively improved, and the conditions of caking and layered precipitation are avoided.
The dietary fiber probiotic composition is prepared from the following raw materials in parts by weight: 10-15 parts of ginseng dietary fiber, 5-8 parts of oat beta-glucan, 3-6 parts of silkworm pupa protein peptide and 1-3 parts of probiotics or probiotic microcapsules.
The oat beta-glucan is a non-starch polysaccharide existing between the endosperm and aleurone layer cell walls of the oats, is a water-soluble polysaccharide, has good effects of reducing blood fat, reducing blood sugar, improving immunity and the like, can be decomposed into short-chain fatty acids by specific flora in intestinal tracts in colon, thereby promoting the growth of probiotics in the intestinal tracts and regulating the intestinal flora, and can improve the water holding capacity of excrement and play a role in relaxing bowel. The ginseng dietary fiber adopted by the invention is insoluble dietary fiber, and the ginseng dietary fiber can mechanically promote intestinal wall tissues and intestinal peristalsis, accelerate the time of food residues passing through the field and facilitate constipation.
However, the probiotics are susceptible to temperature, oxygen and other substances during storage, so that the number of the probiotics is reduced; in addition, the probiotics are easily affected by gastric acid and bile in the digestion process, so that the probiotics are difficult to colonize in the intestinal tract. The probiotic microcapsule is beneficial to improving the survival rate and bioavailability of probiotics.
The preparation method of the probiotic microcapsule comprises the following steps:
s1, inoculating probiotics to an MRS broth culture medium in an inoculation amount of 1-3%, culturing at 32-37 ℃ at a rotating speed of 100-200r/min for 20-24h, and centrifuging at 0-4 ℃ to obtain bacterial sludge;
