Dietary fiber is an important part of a healthy diet

Dietary fiber is a large group of compounds that are not classified as food substances, but, as scientists have established, they should be an integral part of a person's daily diet.


Why does the body need dietary fiber?

Dietary fiber fills the stomach and thus contributes to a feeling of satiety, the release of digestive juices and increased absorption of food. They are also absolutely necessary for the normal functioning of the liver, gallbladder, pancreas, intestines, to prevent constipation, they are involved in the removal of many metabolic products from the body, such as cholesterol, as well as various poisons that enter the body with food and water - mercury, lead etc.

Dietary fiber is a kind of "food" for beneficial intestinal microorganisms, they maintain the necessary composition of the microflora, without which the human body cannot exist normally.

Insufficient content of dietary fiber in the diet is accompanied by functional disorders of the gastrointestinal tract, dysbacteriosis, a decrease in the function of the immune system, an increased risk of developing cardiovascular diseases, obesity, type 2 diabetes mellitus, cholelithiasis, certain cancers, etc. 

What are dietary fibers and where are they found?

Dietary fiber is divided into soluble and insoluble. Soluble dietary fiber is found mainly in vegetables, fruits, legumes; insoluble fiber - in grain products.

Soluble dietary fiber - pectins, hemicelluloses, gums, etc. - have a sorption effect, due to which they contribute to lowering the level of cholesterol and glucose in the blood, remove toxic substances from the body (lead, mercury, cobalt, cadmium, zinc, chromium, nickel and their compounds, radioactive strontium, cesium, zirconium, metabolic products) .

The most famous representative of soluble dietary fiber is pectin. They are rich in vegetables and fruits such as beets, carrots, peppers, pumpkins, eggplants, apples, apricots, quince, cherries, plums, pears, citrus fruits, berries. Including for this reason, sea kale is useful, containing, like all brown algae, soluble dietary fiber - alginates.

Use of soy silk drawing protein

图片
The soy silk drawing protein is a fibrous plant protein with a texture similar to muscle fiber formed by the production and processing of soy protein through a special process. The classification of soy silk drawing protein is divided according to its structure. There are thick silk type, thin silk type, soft silk type, hard silk type, smooth silk, astringent silk, etc. According to the different silk structure and the tensile strength of the silk, how much A combination of plant silk protein can be used to produce ham sausage, minced meat, beef jerky and canned food. The taste of the food is basically the same as ordinary meat food, but the price of plant silk protein is only 1/of the lean pork. 5. The protein content is equivalent to 2-3 times that of fish, meat, and eggs.

 According to market needs, through the selection of different proteases, the adjustment of process conditions and the degree of hydrolysis, a variety of products with different functional characteristics can be developed and produced. (1)Injectable protein isolate :  The product is used in the salted solution for injection of whole meat products, which can reduce the cooking loss of meat products and improve the quality of individual rows and cut surfaces of meat products. Since the product is usually added in a relatively small amount, below 3%, it is not necessary to strictly control the bitterness. Such products are required to have a lower viscosity, and at the same time, the increase in foaming properties and the decrease in gel properties must be controlled within a certain range. The viscosity is mainly determined by the molecular mass of the protein. The greater the molecular mass, the greater the viscosity. 80% of soybean protein has a molecular mass of more than 100,000 and
