Introduction Of White Kidney Bean Extract
White Kidney Bean Extract is derived from the mature seeds of Phaseolus vulgaris—a typical legume herbaceous vine plant. The raw white kidney beans are rich in a variety of nutrients and active functional substances, including basic nutrients such as protein, fat, carbohydrates, as well as high-value active components like phytohaemagglutinin (PHA), α-amylase inhibitors, polysaccharides and dietary fiber, flavonoids, and food coloring.
It also contains a complete range of micronutrients: essential amino acids such as lysine, leucine and arginine, as well as mineral elements including potassium, magnesium, sodium. Different components in white kidney beans undertake distinct beneficial functions:
- Insoluble dietary fiber can reduce the probability of intestinal cancer;
- Water-soluble dietary fiber has the function of regulating sugar and lipid metabolism;
- Flavonoids exert multiple effects such as antibacterial, anti-inflammatory, anti-mutagenic, antihypertensive, detoxification, microcirculation improvement and anti-tumor.
Function Of White Kidney Bean Extract
The core functional component of white kidney bean extract is α-amylase inhibitor (α-AI), a specific glycoside hydrolase inhibitor.
Its functional mechanism is targeted and efficient: it can inhibit the activity of salivary and pancreatic α-amylase in the intestinal tract, thereby hindering the digestion and absorption of starch and other carbohydrates in food. This process can selectively reduce the body’s sugar intake, lower blood glucose levels, and reduce fat synthesis, ultimately achieving the effects of lowering blood sugar, weight loss and preventing obesity.
Notably, the α-AI extracted from white kidney beans has high biological activity, and exhibits a strong inhibitory effect on mammalian pancreatic α-amylase, making it a natural and safe functional ingredient for metabolic regulation.
Application Of White Kidney Bean Extract
- Raw Material for Deep Processing: It can be used as a core raw material for the production of white kidney bean peptides and amino acids, providing high-quality substrate for the development of nutritional supplements and bioactive peptide products.
- Health Food Raw Material: As a high-potassium and low-sodium natural ingredient, it is widely applied in biological health products, and is especially suitable for people with hyperlipidemia, heart disease, arteriosclerosis and those who need to avoid excessive salt intake.
- Functional Ingredient for Metabolic Regulation: Thanks to its natural α-amylase inhibitor, it can be added to products targeting obesity, excess fat, arteriosclerosis, hyperlipidemia and diabetes mellitus, helping to regulate body metabolism and assist in the management of chronic metabolic diseases.
- Specialized Application Fields: It also has application value in the fields of hemostasis and animal genetic analysis, expanding the application scenarios beyond the health product industry.
