The nutritional value of konjac

The 蒟蒻 (scientific name: Amorphophalms konjac), also known as 蒟蒻芋, is commonly known as konjac, thunderbolt, and gong. In ancient China, it was also known as enchanting. Since ancient times, it has been known as “de-intestinal sand,” and Japan is also known as 菎蒻, also known as 菎蒻.

Nutrition analysis

Some types of konjac tubers are rich in konjac polysaccharides, especially the white konjac and flower konjac varieties have a content as high as 50-65%. Konjac polysaccharide, also known as konjac grape mannan, is a linear polymer compound linked by numerous mannose and glucose, linked by beta-1,4-glucoside, linked on its sugar chain side chains. A certain number of acetyl groups, glucose and mannose molecular ratio of 1:1.5-1.7, molecular weight can be as high as 106 Daltons, high viscosity, soluble in water, swelling degree in water, has a specific biological activity.

These characteristics determine that konjac polysaccharide has a variety of uses. In addition to medicine, konjac polysaccharides have a wide range of uses in textiles, printing and dyeing, makeup, ceramics, fire protection, environmental protection, military industry, and oil extraction. In addition, during the processing of konjac flour, 30% to 40% of fly powder is produced. Since the fly powder also contains a certain amount of grape mannan, flying powder is also a natural polymer compound mainly composed of polyhydroxy compounds. Like starch, xanthates can be made and used as soluble heavy metal ions in sedimentation wastewater.

The main ingredient of konjac glucomannan is rich in dietary fiber, various amino acids and trace elements, and the benefits of regular consumption are many:

(1) lower cholesterol, prevent hypertension, and increase blood lipids;

(2) It has a good effect on the prevention and treatment of diabetes;

(3) Prevent obesity and prolong life;

(4) to help digestion and prevent digestive diseases.
