The name of konjac is probably unfamiliar to many people. It is a rhizome plant, also called glucosinolate. China has a very large area for planting. After nearly a decade of research, konjac has been made into Konjac flour. There are hundreds of foods made from konjac. And studies have shown that it has a variety of functions such as lipid-lowering blood sugar and anti-cancer purge. Konjac contains glucosinolates, is a polymer compound, has a strong water absorption, the volume of water after swelling can be 80-100 times, easily digested and absorbed after eating. And can absorb cholesterol and bile acids, have a certain effect on lowering blood pressure and reducing the incidence of cardiovascular disease. Konjac also contains soluble dietary fiber, which is effective in suppressing postprandial hyperglycemia, so konjac flour and its products are ideal hypoglycemic products for diabetics. After application can reduce the burden on the islets.
Konjac is the only economic crop discovered today that can provide a large amount of glucan, and the use value of konjac will be constantly developed and displayed in the field of food and medicine. The edible value of konjac is generally welcomed by people. The main ingredient of konjac is glucomannan, which not only contains more than 10 kinds of amino acids and trace elements required by the human body, but also has low protein, low fat, high fiber, and water absorption. Good, high rate of expansion, medicinal effect. With hypolipidemic, hypoglycemic, lower blood pressure, weight loss, beauty, health care, laxative and more.
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.
