Product Info
What is Pure White Kidney Bean Extract?
Pure White Kidney Bean Extract is a concentrated dietary ingredient derived from *Phaseolus vulgaris*, utilized primarily in weight management supplements to inhibit alpha-amylase and reduce the digestion of dietary starches.
How is Pure White Kidney Bean Extract made?
| Step No. | Production Stage | Key Action | Control Point & Note |
|---|---|---|---|
| 1 | Raw Material Reception | Source and inspect dried white kidney beans (Phaseolus vulgaris). | Source from approved, non-GMO suppliers. Inspect for correct species, moisture content (<13%), and absence of mold, pests, or foreign matter. Reject contaminated lots. |
| 2 | Cleaning & Crushing | Clean the beans to remove impurities and crush them into a coarse powder. | Utilize sieves and de-stoners for cleaning. A consistent coarse grind is crucial for maximizing surface area for efficient extraction without creating excessive fines. |
| 3 | Solvent Extraction | Mix the crushed beans with a food-grade solvent (typically an ethanol/water mixture) in a temperature-controlled extraction tank. | The solvent ratio, extraction temperature (e.g., 50-60°C), and duration are critical for maximizing the yield of the active compound, phaseolamin. Monitor pH. |
| 4 | Filtration & Concentration | Filter the slurry to separate the liquid extract from the solid bean residue. Concentrate the liquid extract using vacuum evaporation. | Multi-stage filtration ensures a clear extract. Concentration under low temperature and vacuum is essential to prevent thermal degradation of the heat-sensitive alpha-amylase inhibitor. |
| 5 | Purification | Pass the concentrated liquid through purification columns (e.g., resin chromatography) to isolate and refine the active components. | This step is key to removing inactive compounds and increasing the purity of the phaseolamin. Monitor elution fractions to ensure effective isolation. |
| 6 | Spray Drying | Atomize the purified, concentrated liquid into a chamber with a stream of hot air to evaporate the remaining solvent and form a fine powder. | Inlet and outlet air temperatures must be strictly controlled to ensure efficient drying without damaging the active ingredient. Final powder moisture content must be low (e.g., < 5%) for stability. |
| 7 | Sieving & Blending | Sieve the dried powder to ensure uniform particle size and blend multiple batches together for lot homogeneity. | A specific mesh size (e.g., 80 mesh) is used to guarantee desired powder characteristics. Blending ensures consistent potency and quality across the entire batch. |
| 8 | Final QC & Packaging | Conduct comprehensive testing on the final blended powder before packaging into sealed containers. | Test for alpha-amylase inhibitory activity (AAIU/g), microbial limits, heavy metals, and residual solvents. Package in airtight, moisture-proof, and light-resistant containers to maintain product integrity. |

Applications & Usage
Common Applications:
weight management supplement
starch blocker
used in nutraceuticals
functional foods
cosmetics (skin conditioning) :contentReference[oaicite:0]{index=0}
Mechanism of action:
| Parameter | Pure White Kidney Bean Extract |
|---|---|
| Functional Category | Amylase Inhibitor; Starch Blocker; Carbohydrate Metabolism Modulator |
| Key Ingredients | Phaseolamin (a glycoprotein alpha-amylase inhibitor); Phytohaemagglutinin (lectin) |
| Mechanism of Action | The active protein, phaseolamin, competitively binds to the active site of alpha-amylase, a key digestive enzyme. This binding action blocks the enzymatic hydrolysis of complex carbohydrates (starches) into absorbable simple sugars (e.g., glucose). The inhibition prevents the breakdown and subsequent absorption of starch-derived calories in the small intestine. |
| Application Effect in Product | Reduces the caloric impact and glycemic load of starchy foods; supports weight management by limiting carbohydrate absorption; helps modulate postprandial blood glucose and insulin response; allows for the formulation of "carb control" dietary supplements and functional foods. |
Comparison:
| Product Name | Category/Type | Key Features | Strengths (vs peers) | Weaknesses (vs peers) | Best Use Cases | Why Choose |
|---|---|---|---|---|---|---|
| Pure White Kidney Bean Extract | Starch Blocker (Alpha-Amylase Inhibitor) | Contains phaseolamin, which inhibits the enzyme that digests complex carbohydrates (starches). | Specifically targets starch absorption from foods like bread, pasta, and potatoes. Non-stimulant. | Does not block absorption of simple sugars. Can cause gastrointestinal side effects like gas and bloating. | Taken immediately before a high-starch meal to reduce its caloric and glycemic impact. | To specifically counteract the effects of starchy foods without altering sugar absorption or using stimulants. |
| InSea2 (Brown Seaweed Extract) | Dual Carb Blocker | Inhibits two enzymes: alpha-amylase (for starches) and alpha-glucosidase (for sugars). | Offers broader carbohydrate blocking by acting on both starches and simple sugars. | Often more expensive. As a proprietary ingredient, it is found within formulas rather than as a single generic extract. | Before meals containing a mix of starches and sugars, such as a pasta dish followed by dessert. | For more comprehensive carbohydrate control that addresses both simple and complex carbs in a meal. |
| Garcinia Cambogia | Appetite Suppressant & Fat Production Inhibitor | Contains Hydroxycitric Acid (HCA) which may block citrate lyase (a fat-producing enzyme) and increase serotonin. | Aims to reduce overall calorie intake by suppressing appetite and potentially limiting fat storage. | Does not directly block carbohydrate absorption. Its effectiveness for weight loss is debated. | For individuals whose primary challenge is appetite control and frequent cravings, rather than specific meal composition. | When the goal is to manage hunger and reduce overall caloric consumption, not just to block carbs. |
| Berberine | Metabolic Regulator (AMPK Activator) | A plant alkaloid that activates AMPK, improving insulin sensitivity and cellular glucose uptake from the blood. | Works systemically to improve the body's fundamental handling of blood sugar. Has broad metabolic benefits. | Does not prevent the initial absorption of carbs from the gut. Can cause significant digestive upset. | As a daily supplement to support healthy blood sugar levels and improve overall metabolic function. | To address the underlying issue of glucose metabolism and insulin sensitivity, rather than just blocking absorption. |
