Five myths about fiber

Fiber is considered to be the ballast of plant foods. On the one hand, it really is not absorbed into the blood, does not provide energy and does not contain nutrients. But at the same time, fiber affects the functioning of almost all systems and organs of our body. How so? Let's break down the most popular fiber myths and find out what its role in digestion and health is.

What is fiber?

Cellulose is called vegetable dietary fiber, which by its chemical affiliation is related to complex carbohydrates. In simple terms, dietary fiber is the cell walls of plants: fruits, vegetables, legumes, nuts, and grains. In grains, fiber is found in the outer layers, which are removed during processing.


Myth 1: fiber is useless for the body

This belief has caused many pathological health conditions to arise and flourish. Although fiber does not contain nutrients, it is a big mistake to underestimate it.

Why is fiber useful?

1. Fiber reduces hunger

Upon entering the stomach, fiber absorbs water and gastric juice. Swelling, it increases in volume. The resulting food lump presses on the walls of the stomach and intestines, and a signal of saturation enters the brain. The feeling of hunger is replaced by a feeling of satiety.

An important condition for starting this mechanism is a sufficient amount of water in the body. Therefore, no later than half an hour before meals, it is recommended to drink a glass of water or herbal tea.

2. Fiber slows down the absorption of carbohydrates and fats

Being in the intestines in sufficient quantities, fiber absorbs excess fats and simple carbohydrates. This helps to slow down the absorption and reduce the total calorie content of the food eaten the day before.

3. Fiber dissolves and removes toxic substances from the body

To the greatest extent, this applies to soluble dietary fibers, which include pectin, gums, polysaccharides.

4. Fiber has antioxidant properties

Dietary fiber prevents the aggressive effects of toxins on the cells of the body.

5. Fiber improves insulin sensitivity.

The intake of fast carbohydrates causes a sharp increase in blood sugar levels and a corresponding release of insulin. After glucose is utilized, its excess is transported to body fat. Intensive production of insulin contributes to the development of insulin resistance - a decrease in the body's sensitivity to insulin. This means that over time, the body requires more and more doses of insulin, and the amount of body fat increases.

6. Fiber promotes colon cleansing

Since fiber is not absorbed by the body, it passes through the intestines in transit, at the same time “sweeping out” the unnecessary.

7. Fiber regulates the intestinal microflora.

Fiber is food for the “good” gut microbes, so its use prevents the appearance of dysbacteriosis. Also, an adequate ratio of protein and fiber in food improves the process of splitting and assimilation of proteins. This, in turn, helps to restore and maintain the balance of the intestinal microflora.

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.

How to use enzyme technology to modify soy protein?

 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
