White kidney bean extract powder is rich in amylase Alpha-amylase inhibitor (α-AI).
Alpha-amylase inhibitor (α-AI) is a kind of nitrogenous carbohydrate or macromolecular protein that can combine with α-amylase and change its conformation, thereby reducing the activity of α-amylase in a variety of legumes and grains. Among them, White kidney bean α-amylase inhibitor is a protein inhibitor that can specifically inhibit human salivary and intestinal α-amylase, delay starch decomposition, and reduce postprandial blood sugar. Coupled with its strong physiological activity and high biological safety, it is widely used in commercial anti-obesity and anti-diabetic products, which are called "starch blockers".
The research on α-amylase inhibitors has been deepening continuously. In 2001, the research on white kidney bean extract achieved a breakthrough success, and a large number of dietary supplements containing white kidney bean α-amylase inhibitors began to appear in the European and American markets.
1. White Kidney Bean Extract powder can block the calories from starchy foods to control weight. The α-amylase inhibitor (α-AI) in white kidney beans can completely block the interaction channel between the substrate and the active site of α-amylase, which reduces the activity of α-amylase in the human oral cavity and pancreas. In this case, starch cannot be completely decomposed into small molecular monosaccharides and absorbed by the human body, so as to control the conversion of starch into calories and be ingested. Eating it before meals can block the enzymatic decomposition of 70%-80% starch and other polysaccharides in the food, reducing and slowing the absorption in the digestive tract, and directly excreted through the end of the digestive tract without affecting the absorption of other nutrients.
2. White kidney bean extract powder can control blood sugar. Alpha-amylase inhibitors can inhibit the activity of salivary and pancreatic amylase in the gastrointestinal tract, hinder or delay the hydrolysis and digestion of the main carbohydrates in food, and reduce the decomposition and absorption of starch carbohydrates in food. It can play a role in lowering blood sugar and blood lipids, and inhibit the increase of blood sugar concentration, so as to meet the dietary habits of diabetic patients.
