What's white kidney bean extract powder?

The white kidney bean, whose biological name is Phaseolus vulgaris, is named for its variety of colors. It belongs to the legume family, butterfly flower subfamily, Phaseolus vulgaris, and white kidney beans are native to Mexico and Argentina in the Americas.
After artificial cultivation and domestication, they have adapted to cold and humid plateau areas. The countries with larger planting areas are Argentina, the United States, and Mexico in the Americas, the United Kingdom in Europe, and China and Japan in Asia. my country only began to introduce and cultivate them at the end of the 16th century. It is planted in various provinces and regions in China. The larger provinces are Yunnan, Guizhou, Sichuan, etc., while Dali, Lijiang, and Lanping in Yunnan have larger planting areas.

Function of white kidney bean

1. The specific glycoprotein structure in the white kidney bean extract (α-amylase inhibitory protein) can combine with the glycoside cleavage site on the α-amylase molecule and cause the conformational change of the α-amylase molecule, making it lose its interaction with amyloside. The ability to bind thereby leads to loss of catalytic activity and is a glycoprotein with N-terminal glycosylation.

2. Experiments show that α-amylase inhibitory protein extracted from Yunnan white kidney bean has lipid-lowering and weight-loss effect on SD rats. After 45 days of high, medium and low doses of white kidney bean extract, it was found that white kidney bean α-amylase inhibitory protein has a significant effect on reducing body weight, visceral fat and total cholesterol in obese rats.

Application in different fields

1. White bean extract powder is used in food field. White bean extract has very high nutritional value and is suitable for cooking.

2. White bean extract powder can be used in the field of health care products.

The content of α-amylase inhibitor determination mainly includes: activity determination, content, purity, relative molecular mass and so on. The main methods used for activity determination are the VanLoos iodine colorimetric method or the 3,5-dinitrosalicylic acid (DNS) colorimetric method. details as follows:

(1) 3,5-dinitrosalicylic acid (DNS) colorimetric method (ie Bernfeld method) equal amounts of the inhibitor to be tested and α-amylase dilution solution were pre-warmed at 37°C for 15min, and then 2% soluble Starch solution, accurately reacted for 5min, added DNS, bathed in boiling water for 5min, took out ice bath for 5min (termination of the reaction). Distilled water was used to replace the inhibitor test solution and α-amylase diluent as the control and blank group. The OD value was measured at 520 nm after diluting to appropriate multiples.

(2) Iodine colorimetry α-amylase diluent and inhibitor solution to be tested were incubated at 37°C for 10min, then added starch solution, incubated at 37°C and shaken for 5min, taken out and cooled to 0°C, added iodine solution, at 660nm The OD value was measured at the bottom.
