White Kidney Bean Extract

Reliable White Kidney Bean Extract Manufacturer & Bulk Supplier

Greenherb operates a certified processing facility specializing in White Kidney Bean Extract, a standardized alpha-amylase inhibitor protein ingredient derived from the seeds of Phaseolus vulgaris through controlled aqueous extraction and ultrafiltration purification. Our production system delivers consistent amylase inhibitor unit specification, verified protein identity, and batch-level analytical documentation. This provides weight management supplement manufacturers and functional food formulators with a dependable supply of this well-characterized legume-derived enzyme inhibitor ingredient.

Why Choose Greenherb White Kidney Bean Extract

Amylase Inhibitor Unit Standardization

Each production batch is verified against a defined alpha-amylase inhibitor unit specification. Standardization by inhibitory activity rather than simple protein content ensures functional performance consistency. Formulators can rely on predictable enzyme inhibition activity per dose across finished product formulations.

Phaseolamin Protein Identity Verification

Our extract is verified for Phaseolamin protein identity by electrophoretic analysis alongside activity testing. This dual verification confirms both the protein’s presence and its functional activity. It distinguishes our ingredient from non-active white kidney bean protein preparations.

Aqueous Extraction Processing

Our extraction uses only water as the processing medium. No organic solvents are involved at any stage. This produces a clean-label ingredient with zero solvent residues. It supports straightforward regulatory classification across supplement and functional food frameworks.

Ultrafiltration Purification

The crude aqueous extract undergoes ultrafiltration membrane separation. This removes low-molecular-weight compounds, sugars, and non-active protein fractions. The purified active protein fraction is concentrated to the target inhibitory activity specification.

Spray-Dried Powder Stability

Liquid extract is converted to free-flowing powder through controlled spray drying. Drying parameters are validated to maintain alpha-amylase inhibitor activity through the thermal drying process. Activity retention through spray drying is confirmed analytically on each production batch.

Heavy Metal and Pesticide Compliance

Every lot undergoes ICP-MS heavy metal screening and GC/LC-MS pesticide residue analysis. Results are verified against EU and US regulatory thresholds before release for commercial supply.

Allergen Declaration Support

White kidney bean is a legume and a recognized potential allergen in some markets. Comprehensive allergen declaration documentation is provided with each shipment. This supports finished product allergen labeling compliance across international food and supplement regulatory frameworks.

Complete Export Documentation

Each shipment includes COA, MSDS, allergen declaration, Non-GMO affidavit, activity certificate, and heavy metal test report. These support regulatory submissions across international supplement markets.

分析証明書

What Is White Kidney Bean Extract

The Functional Protein Behind the Ingredient

Phaseolus vulgaris white kidney bean contains a group of proteins that inhibit the activity of alpha-amylase, the digestive enzyme responsible for breaking down complex carbohydrates into absorbable simple sugars. This inhibitor protein, commercially known as Phaseolamin, is produced naturally in the bean seed. Its biological function in the plant is to deter insect predation. In human digestion, it reduces the rate and completeness of starch digestion when consumed with carbohydrate-containing meals.

Extract vs. White Kidney Bean Powder

White kidney bean powder is produced through simple mechanical reduction of dried bean material. It retains all bean components including starch, fiber, and protein fractions at naturally occurring concentrations. The alpha-amylase inhibitor protein content in crude bean powder is relatively low and inconsistent between batches. White Kidney Bean Extract undergoes selective aqueous extraction and ultrafiltration to concentrate the active Phaseolamin protein to a defined and activity-verified specification. This active protein concentration distinguishes the extract from simple bean powder preparations in supplement applications.

Understanding Alpha-Amylase Inhibition

Alpha-amylase is produced in the salivary glands and pancreas. It cleaves alpha-1,4 glycosidic bonds in starch molecules. This converts complex polysaccharides into maltose and glucose for intestinal absorption. Phaseolamin competitively inhibits this enzymatic cleavage. It reduces the rate of starch hydrolysis in the digestive tract. This mechanism forms the functional basis for White Kidney Bean Extract’s position in carbohydrate management and weight wellness supplement formulations.

製造工程

Seed Sourcing and Qualification

Incoming Phaseolus vulgaris white kidney bean seeds are assessed for botanical identity, alpha-amylase inhibitor activity, moisture, heavy metals, pesticide residues, and microbiological status. Only seeds meeting incoming activity specification proceed to extraction processing.

Cleaning and Dehulling

Seeds undergo mechanical cleaning to remove foreign matter, damaged seeds, and substandard material. Dehulling separates the seed coat from the cotyledon fraction. This concentrates the active protein fraction before extraction.

Aqueous Extraction

Dehulled seed material undergoes controlled aqueous extraction under defined pH, temperature, and time parameters. Water selectively solubilizes the alpha-amylase inhibitor protein alongside other water-soluble bean components. Extraction conditions are optimized to maximize Phaseolamin recovery while maintaining protein activity.

Centrifugal Separation

Crude extract undergoes centrifugal separation to remove insoluble starch, fiber, and cell wall material. The clarified protein-rich supernatant proceeds to ultrafiltration purification.

Ultrafiltration Purification

Clarified extract undergoes membrane ultrafiltration under controlled pressure conditions. This separates the active Phaseolamin protein fraction from low-molecular-weight sugars, salts, and co-extracted compounds. The concentrated active protein fraction is assessed for inhibitor activity before spray drying.

Activity Standardization

Concentrated extract is measured for alpha-amylase inhibitor activity by standardized assay. Controlled blending adjustments achieve target inhibitory unit specification. This ensures consistent functional activity across the production batch.

Spray Drying with Activity-Protective Carrier

Standardized extract is blended with food-grade carrier material. The blend is spray-dried under mild temperature conditions validated to maintain Phaseolamin activity through the drying process. Activity retention through spray drying is confirmed analytically.

Quality Release Testing

Each lot is tested for alpha-amylase inhibitor activity by standardized assay, protein content, moisture, heavy metals, pesticide residues, and microbiological compliance. Batches are released only after activity specification is analytically confirmed.

Protective Packaging

Finished powder is sealed in double-layer PE inner bags with desiccants. Drums are moisture-barrier sealed and stored under cool conditions. Temperature recommendations are provided to maintain Phaseolamin activity throughout shelf life.
