White Kidney Bean Extract Powder is derived from the seeds of Phaseolus vulgaris L., a legume native to Central and South America. White kidney beans are particularly rich in α-amylase inhibitor, which is more concentrated than other black or pinto beans. Compared to other beans, it offers a balanced ratio of protein (19.9g/100g), fiber (6.4g/100g), and essential minerals (e.g., calcium, iron) with fewer calories. α-Amylase Inhibitor in this extract blocks starch digestion by inhibiting pancreatic α-amylase, reducing carbohydrate absorption in some studies. White kidney bean extract also contains many polyphenols and flavonoids, these antioxidants can combat oxidative stress. The U.S. FDA has recognized white kidney bean powder as Generally Recognized as Safe (GRAS), which can be used in products like carbohydrate blockers and functional foods (e.g., bread, shakes). We adopt the acidic extraction combined with the staged ultrafiltration method to optimize the purity and bioactivity of this product, which is suitable for industrial production.

White Kidney Bean Extract Powder is a popular dietary supplement known for its bioactive compounds, particularly alpha-amylase inhibitors. Below is a detailed description of its health benefits, supported by scientific evidence:

★ Weight Management

The extract inhibits alpha-amylase, an enzyme that breaks down starch into glucose, reducing carbohydrate absorption and lowering calorie intake. A 12-week study showed participants lost 5 lbs more than placebo groups when taking 2,400 mg/day. A 2024 randomized trial found dose-dependent reductions in body weight, fat mass, and waist circumference with 700–1,000 mg doses.

★ Blood Sugar Control

By blocking starch digestion, the extract reduces post-meal blood sugar spikes, benefiting prediabetic and diabetic individuals. Higher doses lowered the glycemic index of high-carb foods like white bread.

★ Digestive Health

The extract contains insoluble dietary fiber, which can absorb water, soften stool, increase stool volume, stimulate intestinal peristalsis, and accelerate defecation, thereby reducing the time that harmful substances in the stool come into contact with the intestines and reducing the probability of disease.

★ Cardiovascular Support

Soluble fiber in the extract binds to bile acids, potentially lowering LDL cholesterol. High potassium content helps regulate blood pressure.

★ Antioxidant Properties

Polyphenols and flavonoids in white kidney bean powder can combat oxidative stress, which links to reduced inflammation and chronic disease risk.

We use acidic extraction combined with staged ultrafiltration to produce white kidney bean extract. The specific operation process is as follows:

 Ultrasonic extraction in acidic aqueous solution

a. Crush or grind dry white kidney beans into powder (40~60 mesh).

b. Use dilute hydrochloric acid (HCl), citric acid, or acetic acid to adjust the pH of water to 3.8~4.4.

c. Mix white kidney bean powder with acidic aqueous solution in 1:10~1:20 (w/v) and stir evenly.

d. Perform ultrasonic extraction at 40~60℃ (20~60 minutes, power 200~500W) to promote the dissolution of polysaccharides and α-amylase inhibitors.

e. Centrifuge (3000~5000 rpm, 10~20 minutes) or filter (such as filtration with gauze or filter paper), collect the liquid phase (supernatant), and discard the residue.

 First ultrafiltration

a. Use an ultrafiltration membrane with a molecular weight cutoff (MWCO) of 50~80 kDa (such as polyethersulfone PES or regenerated cellulose membrane).

b. Ultrafiltration operation: pump the liquid phase into the ultrafiltration system and apply proper pressure (0.1~0.5 MPa) for filtration. The first filtrate (molecular weight <50~80 kDa) enters the next stage.

 Second ultrafiltration

a. Use an ultrafiltration membrane with a molecular weight cutoff (MWCO) of 20~30 kDa.

b. Ultrafiltration operation: perform a second ultrafiltration on the first filtrate and collect the second retentate (molecular weight >20~30 kDa). This part is the α-amylase inhibitor product.
