Konjac

Konjac is rich in dietary fiber, protein and amino acids, amino acids, minerals, alkaloids and other nutrients. It is one of the top ten health foods determined by the World Health Organization.

The main component of konjac processing is the glucan glycogen (KGM). The refined powder obtained by processing generally contains more than 65%of the glucancosaccharides. By improving the technology, the content of glucan glycogen in the refined powder can reach about 80%. Essence As a natural high -molecule water -soluble dietary fiber, the calories of glycotose itself are very low, and the benefits of weight loss are multi -angle.

Portate has a good water absorption and expansion. As long as 2 ~ 3 grams of konjac powder, it can swell to about 200 grams of translucent viscous liquid after contacting the water. Therefore, edible konjac products rich in glycotanose can easily make people feel full, delay gastric emptying time, thereby reducing the amount of food.

Like other dietary fiber, the glucan glycogen can also promote gastrointestinal motility, and can also "adsize" toxic and harmful substances and excessive cholesterol, fat, etc., and excrete it with the feces, which helps intestines.

Portal glycogen can be degraded into short -chain fatty acids (SCFA) by microbial fermentation in the large intestine. Short -chain fatty acids can act on hill brain by stimulating intestinal mucosa L cells, and eventually reduce hunger and suppress human appetite.

Konjac

In fact, this is mainly due to the differences in raw materials and processing methods. Because the entire konjac plant is poisonous, it must be processed before it can be eaten. Generally, the lums of the konjac can be grinded, wash the juice with water, then add lime, boil, and then condense, and finally make a gel -like edible form.

The black konjac block is made from rough processing of raw konjac through rough processing. Because raw konjacs have impurities such as leather, the finished products are dark and dark brown.

If the harvested konjac was washed and dried to dry it into a clean powder, and then grinded into a clean fine powder, the konjac fine powder was obtained. Konjac fine powder is generally beige, with almost no impurities, and the particles are very uniform. Konjac shreds made of konjac fine powder are white.

However, some black konjac foods are actually made of fine powder. This is because the manufacturer has added an appropriate amount of powder and other seaweed powder to adjust the color. The same.

Generally, the source of the color of konjac food can be identified according to ingredients. For example, the dark brown konjac block shown in the following Figure A is made from konjac directly; the white konjac shreds shown in Figure B are made of konjac fine powder; although the konjac block shown in Figure C is also dark brown, it is also dark brown, but In fact, it is made of konjac powder. It shows dark brown after adding seaweed sheltering vegetables.
