White Kidney Bean Extract
Introduction
White Kidney Bean Extract is derived from the mature seeds of Phaseolus vulgaris, a legume native to Central and South America and now cultivated worldwide. Traditionally consumed as a staple food, white kidney beans have also been recognized for their beneficial effects on digestion, metabolism, and weight management.
The extract is standardized to contain Phaseolamin, a natural α-amylase inhibitor. This compound slows the breakdown and absorption of carbohydrates, thereby helping regulate blood sugar levels and reduce calorie intake from starchy foods. Research indicates that White Kidney Bean Extract supports weight management, appetite control, and healthy glucose metabolism.
Commercial production involves drying and milling the beans, followed by aqueous or ethanol extraction and purification to enrich the α-amylase inhibitor. The final product is a fine white to off-white powder, stable under proper storage, and widely applied in nutraceuticals, functional foods, and weight management formulations.
