White Kidney Bean Extract Powder

1. Product Fundamentals & Botanical Origin

1.1 Botanical Classification & Geographic Origin (Expanded Scientific Context)

White kidney bean (Phaseolus vulgaris L.) belongs to the Fabaceae family, a plant group widely recognized for its protein-rich seed composition and functional enzyme inhibitor content.

The raw material used by Shaanxi Bolin Biological is primarily sourced from:

· Yunnan-Guizhou Plateau

· Sichuan Basin upland agricultural zones

These regions provide a unique combination of:

· 1,500–2,500 meters altitude (enhances secondary metabolite accumulation)

· Large diurnal temperature differences (improves protein folding stability)

· Mineral-rich, slightly acidic soils (supports enzyme inhibitor biosynthesis)

These environmental conditions contribute directly to the natural enrichment of phaseolin protein fractions, which are critical for downstream extraction efficiency.

1.2 Physical & Chemical Properties (COA-Verified Data Integration)

The product is standardized under strict industrial specifications:

· Appearance: Off-white fine powder

· Odor: Characteristic bean-derived aroma

· Sieve Analysis: ≥95% passes 80 mesh

· CAS Number: 85085-22-9

· CB Number: CB0855527

Key Chemical Indicators (Batch Verified)

· Phaseolin content: ≥1% (actual 1.15%, HPLC)

· Loss on drying: ≤5% (actual 3.28%)

· Residue on ignition: ≤5% (actual 3.12%)

These values indicate:

· Low moisture stability → improved shelf life

· Controlled inorganic residue → refined purification process

· High active retention → stable functional performance

· Shelf life: 24 months under sealed, low-temperature conditions

2. Active Ingredient & Mechanism of Action

2.1 Phaseolin (α-Amylase Inhibitor) Functional Mechanism

Phaseolin is a naturally occurring protein-based α-amylase inhibitor, structurally capable of binding to digestive enzymes responsible for starch hydrolysis.

Mechanistic Pathway (Simplified Industrial Model)

1.         Dietary starch enters gastrointestinal system

2.         α-amylase attempts enzymatic breakdown

3.         Phaseolin binds to enzyme active site

4.         Starch digestion rate is reduced

5.         Postprandial glucose release is modulated

Scientific Context (Non-Clinical Summary)

Peer-reviewed literature indexed in PubMed and EFSA scientific opinions has investigated white kidney bean extract as a carbohydrate metabolism modulator, primarily focusing on:

· Enzyme inhibition efficiency

· Post-meal glycemic response modulation

· Digestive starch bioavailability reduction

Referenced studies include:

· PubMed: 21233123

· PubMed: 23033456

· EFSA Scientific Opinion on α-amylase inhibitors (2011 report)

Shaanxi Bolin Biological ensures standardized extraction maintaining ≥1.15% verified phaseolin content via HPLC, enabling formulation consistency for industrial applications.

2.2 Functional Nutrition Positioning (Non-Medical Claims)

White kidney bean extract is commonly incorporated into:

· Carbohydrate-control formulations

· Weight management nutrition systems

· Energy-balanced dietary supplements

· Functional food systems with glycemic balance positioning

It may support:

· Controlled carbohydrate digestion rate

· Balanced post-meal energy release

· Dietary fiber-enzyme interaction balance

· Healthy lifestyle nutrition frameworks

This ingredient is intended for industrial formulation use only, not for direct therapeutic application.

3. Advanced Extraction & Manufacturing Process

3.1 Proprietary 8-Step Extraction System (Industrial Grade)

Shaanxi Bolin Biological uses a controlled multi-phase extraction system designed to maximize phaseolin retention while removing starch and non-functional proteins.

Process Flow:

1.         Low-temperature raw bean milling (protein preservation phase)

2.         Deionized water extraction (controlled solubilization)

3.         Centrifugal starch separation (density-based removal)

4.         First fine filtration (fiber + macromolecule removal)

5.         Secondary protein fraction separation (Type A protein reduction)

6.         Room-temperature pressure stabilization

7.         Freeze-drying under vacuum (structural preservation)

8.         Sterile micronization and packaging

Engineering Objective:

· Preserve active protein conformation

· Remove non-functional polysaccharides

· Improve solubility and dispersibility

· Stabilize batch-to-batch consistency
