Technical Field

The invention belongs to the field of food processing and production, and particularly relates to rice protein nutrition powder (tablet) for enhancing gastrointestinal health and a production method thereof.

Background

When children are in incomplete growth and development stage, the intestinal and gastric starch hydrolase and protease are less, and the conditions such as constipation, abdominal distension, diarrhea and the like are easily caused. The middle-aged and the elderly people have aging cells, the digestive and absorptive functions of intestines and stomach become weaker, and gastrointestinal diseases occur frequently. Therefore, the development of the food which is suitable for infants and middle-aged and elderly people to enhance the gastrointestinal tract health has great market demand.

The rice, barley, oat and wheat belong to grains, and the content of starch and dietary fiber is high. The human digestion process mainly comprises the specific combination of alpha-amylase and glucosidase with glycosidic bonds on starch molecular chains and hydrolysis. After high-pressure homogenization, alpha-1, 4 and alpha-1, 6 glycosidic bonds in starch molecular chains are degraded, the branch structure of the starch is damaged, the molecular weight of the starch is reduced, and the digestibility of the amylopectin is promoted. In addition, the high-pressure homogeneous shearing and impacting can induce the starch molecule to recombine new high-amylose structure, raise the content of digestion-resisting starch and resist digestionStarch is dietary fiber, part of which is not digested by the small intestine at the front end and is fermented by the small intestine and the large intestine at the rear end, so that the quantity of beneficial bacteria in the intestinal tract is increased. Insoluble dietary fibers in the grains promote intestinal peristalsis to improve digestion, soluble fibers can be completely glycolyzed by bacteria, short-chain fatty acids such as ethyl acetate, propyl acetate and butyl acetate generated after glycolysis can be used as energy sources of intestinal cells and bacteria, the quantity of beneficial bacteria in the intestinal tract is increased, the intestinal peristalsis is promoted, flatulence is reduced, and constipation is improved. In addition, studies have shown that high pressure homogenization can increase the NO contribution of insoluble dietary fibers in pomace^2-And heavy metal Cd²⁺The adsorption capacity of the dietary fiber enhances the physiological function of not allowing the dietary fiber to clear away foreign toxic substances in the intestinal tract. Inulin, also a soluble dietary fiber, is a proliferation factor of bifidobacteria and lactic acid bacteria in vivo, and has the physiological function of improving the intestinal microenvironment. The superfine grinding technology can reduce the particle size of the powder as a whole and improve the solubility and the digestion characteristic of the product.

The rice protein has a TD value (protein digestibility) of 82, a BV value (protein biological value) of 77 and a PER value (protein efficacy ratio) of 1.7, and is comparable to high-quality animal proteins such as eggs, milk and the like. Meanwhile, the amino acid composition of the rice protein is reasonable in balance and very close to the ideal mode recommended by WHO/FAO. But because the protease in the infant is less, the gastrointestinal tract function of the middle-aged and the elderly is weakened, and the digestion and absorption of high-protein food are poor. The rice protein is hydrolyzed into rice peptide by using an enzymolysis technology, and the hydrophobic groups are exposed, so that the solubility of the nutrition powder is improved, and the digestion and absorption of the protein are promoted. In addition, it has been shown that casein enzymatic hydrolysate stimulates mucus secretion in rat intestine, and its action depends on stimulation of opioid receptor, and mucus secretion is also caused by human or other bovine origin containing milk-derived peptides. Similarly, rice protein hydrolysate promotes the release of mucus, thereby protecting the gastric mucosa.

The Coicis semen has effects of invigorating spleen, promoting diuresis, clearing heat, and expelling pus. The red date has the effects of nourishing yin, tonifying yang and enriching blood. The semen Nelumbinis contains amorphous alkaloid N-9 with blood pressure lowering effect, and the nuts (fructus Anacardii, semen Pini, semen Coryli Heterophyllae, semen Cucurbitae) have effects of promoting growth and development, improving body constitution, preventing diseases, and treating arteriosclerosis, hypertension and coronary heart disease. Fructooligosaccharide is an activated proliferation factor of intestinal Bacillus bifidus, and can reduce and inhibit the generation of intestinal putrefactive substances, inhibit the growth of harmful bacteria, and regulate intestinal homeostasis.

The patent (application No. CN 201710522054.8, application date 2017, 06 and 30) discloses a composite protein powder nutritional food formula containing lactoferrin, which mainly comprises concentrated whey protein (containing lactoferrin), whole milk powder, fructo-oligosaccharide, galacto-oligosaccharide, polydextrose, taurine and casein phosphopeptide, and has the effects of enhancing the gastrointestinal function, promoting the absorption and utilization of nutrient substances and promoting the proliferation function of intestinal probiotics. However, the nutritional powder is prepared by simply blending the raw materials, and the existing technology is not utilized to fully process food, so that the performance of the food is improved. The patent (application No. CN 201810200218.X, 3, 12 in 2018) discloses a nutritional powder, which comprises alpha-linolenic acid chelated calcium-alpha-linolenic acid microcapsule powder, red seaweed powder, vitamin D3, alpha-linolenic acid chelated zinc-alpha-linolenic acid microcapsule powder, roxburgh rose powder and zinc gluconate, and is a nutritional powder for supplementing calcium and zinc simultaneously. But the raw material cost is high.

① utilizes the proteolysis technology to open the rice protein structure, expose hydrophobic groups, improve the solubility of unmodified rice protein and promote the release of mucus, thereby protecting gastric mucosa, ② adopts the high-pressure homogenization technology to improve the digestibility of amylopectin and the content of resistant starch (dietary fiber). ③ utilizes the ultramicro pulverization technology to reduce the fineness of food and promote digestion, ④ ensures the content of dietary fiber, improves the quantity of beneficial bacteria in the intestinal tract, promotes the intestinal tract to wriggle, reduces flatulence and improves constipation, and ⑤ adds coix seed, red date, lotus seed, inulin, vitamins, nuts and the like, thereby improving the nutritional value.
