White Kidney Bean Extract


White Kidney Bean Extract is an α-amylase inhibitory protein, a glycoprotein that inhibits the activity of amylase, which is extracted from white kidney beans through patented technology and multiple processing steps. The alpha amylase inhibitory protein from white kidney beans binds to alpha amylase in the human body, forming a polymer, and after the alpha amylase is bound, the spatial structure of the alpha amylase is irreversibly changed, and the alpha amylase is inactivated. In this way, the amylase inhibitory protein in white kidney beans can inhibit α-amylase.

Product Advantages


Yunnan Province is the main producing area of high quality white kidney beans with the largest planting area in China. The local white kidney beans are planted in high altitude and high ultraviolet areas above 1800 meters, with sufficient light and lower average temperatures. As a result, the grains of white kidney beans are fuller and contain higher levels of protein and other ingredients. The white kidney beans used in the production of Control Card® White Kidney Bean Extract come from the high altitude mountainous areas of Dali and Lijiang in Yunnan Province.

Product Application Technology


Tianbao Bio has its own patented extraction process (ZL200910094244. X), which maintains the α-AI spatial structure of the white kidney bean during the extraction process; the extraction process does not require the addition of chemical additives, which ensures the purity, quality and safety of the product.

Test Reports


Control Card® White Kidney Bean Extract has completed toxicology experiments, animal experiments and human clinical function experiments for the dietary and living habits of the Chinese population, and has obtained test reports to confirm its safety and efficacy.

popularization of science


White kidney bean extract can reduce starch calorie absorption by limiting the activity of the body's amylase enzyme, which reduces and delays the conversion of starchy foods to sugar without affecting the absorption of other nutrients.

Technical Advantages


Innovative process to increase temperature resistance, unlocking more forms of application, unlocking more ways of consumption! Can be processed at high temperature, brewed at high temperature for consumption, cookies, bread, no-cook rice, convenience food ......

Control Card® No-Cook Rice


For people who crave for the delicious taste of rice but are worried about the high glycemic index of traditional rice, Tianbao Bio has collaborated with a number of organizations to develop Control Card® No-Cook Rice. The no-cook rice with white kidney bean extract will not destroy the flavor of the rice, and also reduce the cooking process.

WONDERLAB White Kidney Bean Pressure Candy


The innovative germplasm variety, Brassica alba L. 1 (YWL1), jointly developed by Tianbao Bio and the Grain Crops Research Institute of Yunnan Academy of Agricultural Sciences, has a higher proportion of amylase inhibitors, higher activity and higher yield. The white kidney bean extract extracted through this variety has outstanding activity performance and possesses a number of unique and advantageous properties. At present, it has been supplied to WONDERLAB, a well-known domestic health nutrition brand and a strategic partner of Tianbao Birch.
