Description

Process for preparing functional food by utilizing natural selenium-rich radix puerariae residues
Technical Field
The invention relates to a process for preparing functional food by utilizing natural selenium-rich radix puerariae residues, belonging to the technical field of agricultural and forestry waste recycling food processing.
Background
Protein, fat, carbohydrate, vitamins, minerals, water, six nutrients required for human life and healthy growth; in recent years, a substance named as "dietary fiber" is coming into the sight of scientists, and is a special carbohydrate which cannot be decomposed by digestive tract enzymes of human bodies, but has important physiological functions and also becomes an indispensable substance for human bodies, so that the carbohydrate is called as "the seventh major nutrient" of human beings, the requirement on food is more and more refined along with the improvement of living standard of people, the content of crude fiber in the ingested food is less and less, modern "civilization diseases" such as constipation, obesity, arteriosclerosis, cardiovascular and cerebrovascular diseases, diabetes and the like seriously threaten the body health of modern people, and the supplement of dietary fiber in the food of people becomes urgent. Scientific research proves that proper dietary fiber needs to be taken to ensure human health. The proper dietary fiber intake can help gastrointestinal peristalsis and promote digestion and absorption of food; the dietary fiber also has strong water absorption, and can carry excessive nutrition out of human body when the nutrition is excessive, thereby facilitating excretion of feces and preventing constipation. Meanwhile, a plurality of harmful and toxic factors can be brought out of the body. The dietary fiber is often supplemented, so that the health constitution can be maintained, and various diseases such as coronary heart disease, diabetes mellitus and the like can be effectively prevented. The british national consultant committee recommends dietary fiber intake of 25-30 g/day per population; the FDA recommended total dietary fiber intake in the United states is 20-35g per day for adults; the relevant organization in Australia indicates that 25g of dietary fiber is taken by people every day, and the morbidity and mortality of coronary heart disease can be obviously reduced. The Chinese Nutrition society proposes in 2000: the suitable intake of dietary fiber for adults in China is about 30g per day. According to measurement and calculation, the daily actual intake of all people in China is only about 14 g, the intake is seriously insufficient, and the intake gradually declines along with the improvement of the fine processing level of food; at present, the problem of nutrient deficiency of dietary fiber is not an individual problem and becomes a public problem.
The application of dietary fiber in the food industry is quite common, and particularly, the dietary fiber-containing bread, beverage, biscuit, dairy product and the like in supermarkets or convenience stores in European and American countries are all similar; about 20% of the instant cereal foods are functional foods rich in dietary fiber; the same European and American countries in Japan are also popular with dietary fiber foods, and more than 70% of functional drinks contain dietary fiber. In recent years, the structure of global food is being adjusted toward fibrous food. The consumption demand in japan and the usa increases at a rate of 10% per year; in developed countries, food enterprises attach great importance to the development of low-carbohydrate, low-calorie and low-fat foods aiming at the prevalence of hypertension, hyperglycemia and overweight. Over 1000 low calorie, low carbohydrate products have been introduced into the market in the united states for the past five years, and the price has remained the same. Numerous dietary fiber-supplemented fiber beverages, low-energy chocolate and nutrition bars, sports drinks, lactic acid bacteria beverages, milk tablets, etc. are available in the japanese market. International markets outside japan also emerge with a number of innovative fiber-fortified foods such as low-carbohydrate ice cream, fruit mates, yogurt, cookies, low-energy instant coffee, and the like. Most of these new products are introduced by international famous food companies such as Nestle, Dynence, Kafu, Unitrary, etc. Similarly, domestic food enterprises also need to pay attention to the development of dietary fiber foods. According to the survey of the current health status of residents in China, the daily intake of dietary fiber of a standard Chinese adult is only 18.7g and is far lower than the daily intake of 30.2g suggested by the Chinese Nutrition society, the overweight rate of Chinese adults reaches 22.8 percent (about 2 hundred million people), the prevalence rate of dyslipidemia reaches 18.6 percent (about 1.6 hundred million people), and overweight and dyslipidemia people are all rising sharply. The deficiency of dietary fiber intake is one of the important reasons for causing modern diseases, and food huge enterprises in China such as Mongolian cattle, illite, Guangming, Waha, farmer mountain spring and the like have recently been introduced to health foods rich in dietary fiber in two years, but most of the food is concentrated in the field of health foods and beverages, and the share of common foods is relatively small;
the dietary fiber is divided into two categories of water-soluble fiber and water-insoluble fiber, wherein the water-insoluble fiber comprises cellulose, hemicellulose and lignin; the physiological functions of different dietary fiber products are different in strength, and not all dietary fibers have good physiological functions. Generally, dietary fiber which is merely used as an energy-free filler is called ordinary dietary fiber, and dietary fiber which is used as a physiologically active substance is called high-quality dietary fiber. Several typical high quality dietary fibers found on the market are: inulin, polydextrose, resistant starch, chitosan, oat beta-glucan, and the like. The high-quality dietary fiber not only can be metabolized and fermented to a greater extent and more quickly in the large intestine and can be more easily utilized by intestinal beneficial bacteria, has the effects of controlling weight, regulating blood sugar, reducing blood fat, reducing cholesterol and the like, but also has good taste and texture, and is not rough in taste and natural in taste like the impression of people. In addition to the improvement of the mouthfeel, the processing performance of the high-quality dietary fiber is greatly improved, such as high stability and easier dissolution, and the color, transparency and shelf life of the beverage are not influenced when the high-quality dietary fiber is added into the beverage; the additive can bring more excellent texture characteristics when being added into bread; when the product is added into ice cream, the product can replace fat and sugar, and maintain rich fat feeling; therefore, the dietary fiber food can be added into food more easily without affecting the characteristics of the food, and brings more excellent quality for the food, which is also the reason of the obvious trend that high-quality dietary fiber food is gradually increased in developed countries abroad in recent years, and common dietary fiber food is gradually faded out of the market;
the kudzu root has the functions of clearing away greasy heat, eliminating phlegm, relieving cough and reducing blood sugar, and can protect the health of heart and cerebral vessels; wild radix Puerariae contains a large amount of dietary fiber, and has effects of relieving constipation, removing toxin in vivo, and reducing carcinogenesis; relieving hangover, invigorating stomach, protecting liver; the radix Puerariae powder can regulate human body function, enhance body constitution, improve organism disease resistance, resist aging and prolong life; the radix Puerariae isoflavone has high phytoestrogen, and can activate ovary activity and make skin smooth and tender. In addition, in the production practice, the radix puerariae with high puerarin content is found to be in a selenium-rich belt, so the radix puerariae produced by people has higher selenium content. Selenium is one of 14 trace elements essential to human health and animal body, has three biological functions of nutrition, toxicity and detoxification, and is called as life protective agent, and selenium deficiency in vivo can cause various diseases such as hepatic necrosis, myocardial degeneration, pancreas atrophy and fibrosis, muscular dystrophy, keshan disease, Kashin-Beck, cataract and the like. Selenium has effects of protecting myocardium health, preventing cardiovascular and cerebrovascular coronary heart disease, arteriosclerosis, resisting oxidation, resisting aging, and enhancing immunity. The total dietary structure survey results carried out in the early 90 th century show that the average value of the selenium intake in the daily diet of Chinese residents is 43.3 micrograms per day, which is lower than the lower limit of the recommended lower limit of the suitable selenium intake of 50 micrograms per day by the Chinese society of nutrition; the existing forms of selenium comprise inorganic selenium and organic selenium, but the inorganic selenium has higher toxicity, and the organic selenium is superior to the inorganic selenium in the aspects of safety, biological activity, bioavailability and the like; the pueraria flavone or puerarin extracted from the pueraria is generally extracted by high-concentration alcohol, in the pharmaceutical industry, the pueraria flavone or puerarin is generally extracted by high-concentration alcohol, a large amount of crude fiber, lignin, pueraria polysaccharide and the like are still stored in the extracted pueraria residue, and the pueraria residue used in the application is natural selenium-rich pueraria residue. The radix Puerariae polysaccharide has effects of resisting oxidation, enhancing immunity, lowering blood sugar, reducing blood lipid, and inhibiting bacteria.
