High activity alpha-amylase inhibitor proteins extracted from selected seeds of Phaseolus vulgaris White Kidney Bean Extract Powder Hefei Fushan Yuansheng Biotechnology Co., Ltd. Our extract has standardised activity levels of 8,000 to 20,000 AAIU/g in three specifications (Carb-block ≥10,000u/g, DL ≥8,000u/g, P40c ≥20,000 AAIU/g) that will provide consistent effectiveness across carbohydrate management formulations.
We are armed with 500 tons/year capacity, and the certifications like FDA, GMP, ISO, HALAL to deliver the trustworthy raw materials to worldwide nutraceutical companies for the weight management and metabolic health goods. The sophisticated extraction technique maintains the pharmaceutical-grade purity and natural bioactivity of phaseolamin.
Phaseolamin is found in white kidney bean extract. This is a natural glycoprotein that temporarily blocks alpha-amylase, the enzyme that breaks down the carbs you eat into sugars that can be absorbed. When paired with a well-rounded diet, this process helps promote a better post-meal glucose response.
Our extract is derived from selected white kidney beans grown in the best cultivation areas. The way you phrase it will provide predictable outcomes, since the amount of active ingredients stays steady throughout processing.
Each batch is rigorously tested using the Iodin Colorimetric Method to validate activity levels. It is a light yellow fine powder that is freely soluble and may be included easily into a variety of dosage forms.

We have a closed loop manufacturing system that preserves the integrity of ingredients from the selection of raw materials through to final packaging. We start by collecting high-quality white kidney bean seeds from proven producing areas, followed by stringent cleaning and drying processes.
The extraction step is a combination of hot water extraction and alcohol precipitation to retain active chemicals and remove undesirable macromolecules. The extract is subsequently purified to pharmaceutical standards using ultrafiltration membrane technology to increase both purity and activity levels.
Low temperature vacuum concentration (50°C) prevents degradation of heat-sensitive phaseolamin. The concentrated extract is spray dried to produce fine powder at specified moisture content (≤5.0%) to optimise stability and dissolving qualities.
Each batch is completely quality verified and packed in food grade aluminium foil bags with cardboard drums. Three-layer protective system keeps moisture, light and contaminants away during storage and transport.
1. Premium Raw Material Selection
We source beans exclusively from certified cultivation areas where climate and soil conditions optimize phaseolamin content. Pre-processing protocols eliminate contaminants while preserving natural potency.
2. Proprietary Extraction Technology
Our patented multi-stage purification system achieves superior active ingredient retention compared to conventional methods. Temperature-controlled processing maintains molecular integrity throughout production.
3. Multi-Tier Quality Assurance
From incoming material inspection to finished product release, we implement over 20 quality checkpoints. Full traceability systems document every production phase, ensuring "source traceable, flow trackable, accountability clear" standards.
4. Sustainable Supply Practices
We have a 500 tonne capacity per year and via effective inventory management we are able to handle small-batch testing as well as big scale commercial orders. We use environmental guidelines to keep the waste minimum and output quality constant.

Dietary Supplements
Our White Kidney Bean Extract Powder is excellent for capsules, tablets and powdered formulations. The tiny particle size offers uniform dispersion in mixes and the neutral flavour profile does not impact the flavour of flavoured goods.
Functional Foods
Applications Use in baked goods, cereal bars and snack items for carb-conscious customers. The extract has good stability at typical food processing temperatures and retains action throughout manufacture.
Beverage Solutions
It is ideal for use in ready-to-drink products, protein shakes and smoothie mixes. Superb solubility characteristics avoid settling and the resultant dosage variations over the shelf life of the product.
Specialty Dairy Products
Works well with yoghurt drinks, ice cream, and dairy desserts. The extract incorporates well without impacting texture or creating precipitation concerns which are the norm with lesser grade materials.
