What is White Kidney Bean Powder?
White Kidney Bean Powder is extracted from Phaseolus vulgaris Linn. It is a plant resource with the same origin as medicine and food, with the highest yield in Asia (45.44%). The edible value of the white kidney beans lies in their rich amino acid content, and its proportion conforms to the reference protein model proposed by FAO/WHO and is a full-value protein.
The medicinal value lies in one of the glycoproteins, α-AI, an α-amylase inhibitor. White Bean Powder can effectively reduce postprandial blood sugar levels, providing a new choice for diabetic diets. In addition, the polysaccharides, polyphenols, and mineral elements in white kidney beans provide them with a wide range of biological activities. Such as anti-oxidation, anti-obesity, etc., the above factors make it a medicinal and edible homologous plant with great development potential, and it has attracted great attention from food and drug companies and related research institutions.

What are the main functional ingredients of White Kidney Bean Powder?
Glycoprotein:
1. α-AI
α-AI has a molecular mass of 28 800 and acts mainly on mammalian and insect α-amylases. Early use of the supercritical carbon dioxide method can extract α-AI from white kidney beans up to 12% but often mixed with trypsin inhibitors and lectins. The former can stimulate the pancreas to produce too much amylase, impairing or completely inhibiting α-AI activity. At present, the inhibition rate of α-AI extracted from white kidney beans can reach more than 90%.
2. PHA
The PHA species isolated from different varieties of white kidney beans are not single. One is a 50kD homodimeric protein composed of two 30ku monomers. One is isolated from a small white kidney bean with an apparent molecular mass of 136 Ku, which is a tetramer composed of subunits of 2 molecular masses (36.2 Ku and 32.2 Ku), with a sugar content of 4.93%. There is also a PHA with a molecular mass of 30~40 Ku and a specific activity of 1193.62 HU/mg.
polysaccharide
White Kidney Bean Powder is a rich mixture of many types of pectin. It has hypoglycemic, hypolipidemic, and good in vitro antioxidant effects. The basic physicochemical properties and molecular mass distribution of polysaccharides after high-pressure microfluidization did not show significant differences, but the monosaccharide composition changed to some extent. The molecular mass distribution of non-starch polysaccharides is not uniform. The relative molecular masses of the three components are 300.67, 222.30, and 18.16 Ku, respectively, which are hybrid polysaccharides containing α-type pectin structure.
1. Pectin
Soybean skin cell wall is rich in xylogalacturonic acid (XGA), homogalacturonic acid (HG), rhamnogalacturonic acid (RG-I) pectin, with polygalacturonic acid, and typical arabinogalactose structure.
2. Dietary fiber
The hull quality of white kidney beans accounts for 7.5%~8.0% of the granule quality. It has a higher content than soybeans and is an excellent raw material for dietary fiber. The mass fractions of soluble dietary fiber and insoluble dietary fiber were 3.5% and 19.8%, respectively. Soy flour contains 1.14% soluble fiber, and bean dregs contain 43.49% insoluble dietary fiber. White kidney bean soluble dietary fiber is mainly composed of arabinose, galactose, glucose, mannose, and galacturonic acid. Among them, arabinose and galactose are the two main neutral sugars, and the content of arabinose is higher than that of galactose.
3. Resistant starch
Resistant starch is similar in properties to soluble fiber and has a certain effect on regulating body fat.
4. Polyphenols
The antioxidant activity of white kidney beans is reflected in the richness of polyphenols.
In addition, white kidney beans have other active components, such as peroxidase, oligosaccharides, saponins, beta-carotene tocopherols, saponins, and rich minerals such as K, Ca, and Mg. This lays the material basis for its wide range of biological activities.
