Description

A kind of preparation method of highly active dietary fiber

Technical field:

The invention belongs to the field of health food.

Background technique:

In recent years, due to the improvement of national living standards and changes in dietary structure, excessive intake of high-protein and high-fat foods (mainly animal protein and fat) has also been caused. The fineness of grain food intake is high, and dietary fiber The proportion of intake of food is relatively reduced, and many "civilization diseases" related to dietary structure have increased significantly. For example, intractable constipation, colitis, gallstones, diabetes, arteriosclerosis, hyperlipidemia, obesity, etc. In order to prevent the occurrence of such "civilized diseases" and treat such diseases, we should first start with dietary catering and increase the intake of highly active dietary fiber. Because the preventive and therapeutic effects of dietary fiber on the above diseases are significantly related to their own performance and components.

With the emergence of modern "disease of civilization" and the research on its function, more and more people realize the importance of dietary fiber in nutrition and health care, and they have also invested great enthusiasm in the research and development of dietary fiber. Developed countries and regions such as Japan, the United States, and Japan have developed and produced many varieties of dietary fiber and highly active dietary fiber foods, which are quite popular with consumers. In recent years, there have been many reports on the extraction and production of dietary fiber in my country, but the development of most products is still in the laboratory research, and has not yet formed a scale of mass production; on the other hand, many people have little understanding of dietary fiber. It is only understood as crude fiber and cellulose, etc. Therefore, the research and development of dietary fiber and dietary fiber functional food has important practical significance for promoting people's health and improving the competitiveness of the food industry in domestic and international markets. A large number of experiments have proved that the use of dietary fiber has significant clinical effects in reducing blood lipids, preventing constipation, preventing cancer and cardiovascular diseases. This has been confirmed by a large number of research facts and epidemiological findings at home and abroad, and it has been applied in the food industry.

Dietary fiber of the present invention has following main health-care effects to human body:

Dietary fiber has many important physiological functions to human health, which has been confirmed by a large number of research facts and epidemiological investigation results at home and abroad, and has been confirmed by modern medicine and nutritionists as the next step in protein, fat, carbohydrates, vitamins, It is the seventh largest nutrient after minerals and water, and also shows many special physiologically active functions.

1. Expanding properties and the function of preventing intestinal diseases

Dietary fiber has strong water absorption. After entering the digestive tract, it absorbs water and swells in the stomach. It is ready-made high-viscosity sol, which stimulates gastrointestinal peristalsis, increases defecation speed, reduces intestinal pressure, and produces laxative effect. It can be used to prevent constipation. , intestinal diverticulosis, diaphragm disease and hemorrhoids and other diseases.

Because dietary fiber absorbs water and expands in the gastrointestinal tract, it produces a feeling of fullness, which can reduce food intake and energy intake. At the same time, it inhibits the diffusion rate of nutrients in the intestinal tract and reduces the absorption rate of fat in the small intestine. Long-term consumption can use the fat in the body. Store fat, so as to achieve the purpose of weight loss.

2. The characteristics of adsorbing organic matter and the function of preventing cardiovascular and cerebrovascular diseases

Dietary fiber has the property of adsorbing organic molecules such as bile acid, cholesterol, and mutants. Dietary fiber entering the intestine can chelate cholesterol in the intestine, reduce the synthesis and absorption of exogenous cholesterol, bile acid, and salts, and limit the bile The enterohepatic circulation of acid hinders the reabsorption of endogenous cholesterol and neutral fatty acids; dietary fiber can also promote the conversion of cholesterol into bile acid and bile salt, and accelerate the excretion of bile salt and lipid substances. Therefore, dietary fiber can be used to prevent cholelithiasis, hyperlipidemia, obesity, atherosclerosis, coronary heart disease and other diseases.

3. Detoxification and blood pressure lowering function

Dietary fiber molecules are weakly acidic and have the function of ion exchange resins. They can absorb heavy metal ions such as lead, mercury, and cadmium in the human intestinal tract, reduce the absorption of toxic heavy metal ions, accelerate the excretion of toxic ions, and play a detoxification role. Dietary fiber can also exchange with sodium ions in the gastrointestinal tract, so that a large amount of sodium ions are excreted with the feces, and the ratio of Na ⁺ /K ⁺ in the blood becomes smaller, thereby producing a hypotensive effect.

4. Regulating the characteristics of glucose metabolism and hypoglycemic function

Dietary fiber can increase the viscosity of intestinal juice, hinder the absorption of glucose, bind glucose, and reduce the effective concentration of intestinal glucose; affect the degradation of starch by α-amylase, prolong the enzymatic hydrolysis time, and reduce the release rate of glucose in intestinal juice; Tissue sensitivity to insulin, reduce the body's demand for insulin, thereby reducing blood sugar levels in diabetics.

5. Regulating intestinal flora, free radical scavenging properties and anti-cancer function

After dietary fiber enters the large intestine, it can be selectively decomposed by intestinal bacteria, inhibit the growth of saprophytic bacteria, promote the reproduction of probiotics, reduce the carcinogens produced by saprophytic bacteria, promote the production of butyric acid by probiotics, and adjust the pH value in the intestine. Inhibit the growth of tumor cells and promote the death of the cells, thereby preventing the occurrence of cancer; dietary fiber is utilized by microorganisms in the colon, which promotes the release of ferulic acid bound to it, and ferulic acid has strong antioxidant activity and scavenging free radicals, thereby preventing the occurrence of tumors in the intestinal tract.

Application effect of the present invention:

A large amount of active dietary fiber present in the plant is concentrated and extracted from alfalfa, and its content is as high as more than 75%. It is a polysaccharide with rich resources and multiple physiological functions. It plays an extremely important role in preventing certain diseases and protecting people's health, and is an ideal raw material for functional health food. In addition, it is also widely used in baked foods, such as bread, biscuits, cakes, peach cakes and other baked foods, and its dosage is generally 5%-10% of flour. Alfalfa dietary fiber can be used to make steamed bread, noodles , In instant noodles, the dosage is generally 5%-6% of the amount of flour. After mixing alfalfa dietary fiber with caramel pigment, animal fat, behenic acid, trace elements and other nutrients and xylitol sweetener, heating It can be used as a dietary fiber filling, which can be used in pasta products such as beef patties, snack fillings, hamburgers, etc., and the effect is very good.
