White kidney bean derived from Mexico and was introduced to China about 400 years ago. White kidney bean is consumed like other beans as a nutritious vegetable and a tonic in promoting digestion, tonifying kidney and bringing other benefits to health.
Modern Research------carbohydrate inhibitor
Recent research shows that white kidney bean extract can inhibit activity of alpha-amylase enzyme. Alpha-amylase plays a key role in the digestion of foods. As a digestive enzyme, alpha-amylase is required for the metabolism of starchy carbohydrates.
As White kidney bean extract may block the action of the digestive enzyme alpha-amylase, this product may prevent the breakdown of starch into dextrin and ultimately glucose. Therefore white kidney bean extract will result in some ingested starches passing through your system undigested (Jay K Udani etc, 2009).
Application:
1. Dietary Supplement as antioxidant
2. Functional foods and beverage
