Alpha-Amylase Inhibitor Activity (Phaseolamin) By Enzyme Assay
Mechotech designs and manufactures turnkey herbal extraction plants for White Kidney Bean (Phaseolus vulgaris) seed extract, standardised for phaseolamin activity — an alpha-amylase inhibitor protein rather than a small-molecule marker compound. Because phaseolamin is a functional protein, its potency is defined by enzyme-inhibition activity assay rather than a simple HPLC assay percentage, which shapes the plant's design around gentle aqueous extraction and protein-preserving downstream processing instead of high-temperature solvent extraction. We supply the complete machinery — bean cleaning, milling, aqueous extraction, clarification, ultrafiltration/concentration, and low-temperature drying — to process White Kidney Bean seed into a consistent, activity-standardised extract for the nutraceutical and weight-management ingredient industries.
Mechotech's White Kidney Bean plant is engineered around the specific processing demands of a heat-labile protein active: aqueous (non-solvent or minimal-solvent) extraction is used to solubilise phaseolamin from the bean without denaturing its enzyme-inhibitory structure, and downstream concentration is performed by membrane and low-temperature vacuum methods rather than high-heat evaporation. Built in SS 316L with electropolished product-contact surfaces, PLC-based automation and full batch documentation, each plant is delivered as a commissioned turnkey system engineered to the declared alpha-amylase inhibitor activity specification, verified by enzyme-inhibition assay rather than a conventional HPLC percentage.

Plant Capacities
| Plant Scale | Bean Throughput | Typical Use |
|---|---|---|
| Pilot | Configured to your feedstock and trial plan | Product development, activity-yield validation |
| Semi-Commercial | Configured between pilot and commercial scale | Contract manufacturing, scale-up trials |

Capacity is configured to raw-material supply and confirmed buyer volume; because phaseolamin activity is protein-based and assay-dependent, we recommend a pilot plant to validate inhibitory-activity yield before scaling.
Manufacturing Process
Raw Material Cleaning & Size Reduction
Dried White Kidney Bean seeds are cleaned to remove debris and foreign matter, then milled to a uniform particle size that exposes the bean's internal protein fraction to aqueous solvent before extraction.
Controlled Aqueous Extraction
Milled bean is charged into closed, jacketed SS 316L extraction vessels and extracted with controlled-temperature aqueous solvent, kept below denaturing temperatures to preserve the phaseolamin protein's alpha-amylase inhibitory structure.
Solid-Liquid Separation & Clarification
The extract slurry is clarified through a plate-and-frame filter press to remove bean fibre, starch residue and insoluble matter, yielding a protein-bearing filtrate.
Membrane Ultrafiltration & Concentration
The filtrate is concentrated by membrane ultrafiltration and/or low-temperature vacuum evaporation, selectively concentrating the protein fraction while limiting thermal exposure that would reduce enzyme-inhibitory activity.
Activity Standardisation
The concentrate is assayed by in-vitro alpha-amylase inhibition assay (rather than HPLC) and adjusted to the declared inhibitory-activity specification before drying.
Low-Temperature Drying & Quality Control
The standardised extract is spray-dried under a low-inlet-temperature profile, or freeze-dried for higher-activity grades, then released after enzyme-activity assay, protein content, heavy-metal, microbial, and moisture testing with full certificate-of-analysis documentation.

Key Features
GMP Hygienic SS 316L Construction
Electropolished SS 316L product-contact surfaces use GMP hygienic design, with CIP operation between batches.
Protein-Preserving Aqueous Extraction
Low-temperature aqueous extraction is used in place of high-heat solvent extraction to protect the phaseolamin protein's enzyme-inhibitory activity.
Membrane-Based Protein Concentration
Ultrafiltration concentrates the active protein fraction without the thermal stress of conventional evaporation, preserving inhibitory activity.
Activity-Based Standardisation
In-process and batch-release enzyme-inhibition assay are used to check the finished extract against its declared alpha-amylase inhibitor activity specification, rather than a simple HPLC percentage.
Low-Temperature Drying Options
A matched low-inlet-temperature spray dryer or freeze dryer produces a free-flowing powder while preserving protein activity for higher-grade output.
Scalable Batch Capacity
Plants are configured to requirement from pilot scale upward, with modular expansion.
