White Kidney Bean Extract Powder
White Kidney Bean Extract is a botanical ingredient derived from the seeds of Phaseolus vulgaris, commonly known as the common bean. It is widely used in the nutraceutical industry, particularly in dietary supplement formulations related to carbohydrate metabolism and weight management.
One of the key characteristics of this extract is its alpha-amylase inhibitory activity. Alpha-amylase is a digestive enzyme involved in breaking down dietary starch into smaller carbohydrate molecules. Certain proteins naturally present in common bean seeds can inhibit this enzyme under appropriate conditions.
As demand for botanical ingredients continues to develop, manufacturers need more than a plant extract with a general product name. They need clearly defined specifications, suitable analytical methods, batch consistency, and reliable supplier support.
Shaanxi Ruiwo Phytochem Co., Ltd. provides White Kidney Bean Extract with different specification options to support the formulation and purchasing requirements of international customers.
What Is White Kidney Bean Extract?
White Kidney Bean Extract is obtained from the seeds of white kidney beans, botanically identified as Phaseolus vulgaris L. The common bean belongs to the Fabaceae family and is cultivated in many regions around the world.
White kidney beans contain several naturally occurring proteins, including alpha-amylase inhibitors. One commonly discussed inhibitor is known as phaseolamin.
Unlike ordinary white kidney bean powder, which is mainly a ground botanical food ingredient, a concentrated extract is processed to obtain selected components or functional characteristics from the raw material.
For ingredient buyers, the distinction is important. A standardized extract should be evaluated according to its declared specification, active or functional indicator, and corresponding analytical method rather than relying only on the botanical source.
Specifications
Ruiwo offers different specification options to meet the needs of dietary supplement manufacturers, ingredient distributors, and formulation developers.
| Product | Specification |
|---|---|
| Product Name | White Kidney Bean Extract |
| Botanical Name | Phaseolus vulgaris L. |
| Plant Part | Seed |
| Available Specifications | 1%, 2%, 20,000 U/g |
| Functional Characteristic | Alpha-Amylase Inhibitory Activity |

Important specification note: The 1% and 2% grades are percentage-based specifications, while 20,000 U/g refers to enzyme inhibitory activity per gram. These values represent different measurement approaches and should not be directly compared or converted without a clearly defined analytical basis.
For percentage-based specifications, buyers should confirm the exact marker or test indicator represented by the percentage. For activity-based specifications, the testing procedure, enzyme source, substrate, pH, and calculation method are important when comparing products from different suppliers.
Please contact Ruiwo for the latest TDS and COA to confirm the specification that matches your requirements.
Applications of White Kidney Bean Extract
White Kidney Bean Extract is mainly used as a functional botanical ingredient in the nutraceutical and dietary supplement industries.
Weight Management Formulations
White kidney bean extract is commonly selected for nutritional products developed for weight management. Its relevance comes from the alpha-amylase inhibitory properties of certain bean proteins.
It may be incorporated into multi-ingredient formulations alongside other nutritional ingredients, depending on the product concept and regulatory requirements of the target market.
Carbohydrate Metabolism Support Products
Because of its relationship with starch digestion, white kidney bean extract is also used in formulations positioned around carbohydrate metabolism support.
Manufacturers should ensure that product claims are supported by appropriate scientific evidence and comply with the regulations of the markets where the finished products will be sold.
Dietary Supplement Manufacturing
Depending on the selected grade and formulation process, White Kidney Bean Extract Powder can be considered for different supplement formats, including:
- Hard capsules
- Tablets
- Powder blends
- Multi-ingredient dietary supplements
- Functional nutrition products
Final formulation suitability should be evaluated through compatibility, stability, processing, and finished-product testing.
