Kudzu Root Extract Powder

Kudzu Root Extract Powder
Mechotech designs and manufactures turnkey extraction plants for Kudzu Root Extract Powder, processing the dried root of Pueraria lobata into an extract standardised to 20%-40% Puerarin isoflavones by HPLC. Puerarin is a well-documented isoflavone C-glycoside — chemically distinct from the more common O-glycoside isoflavones found in soy and other legumes, which makes it notably more resistant to acid/enzymatic hydrolysis and shapes the extraction chemistry around this raw material specifically. Kudzu root also carries a substantial native starch fraction, unlike most nutraceutical roots, requiring a dedicated starch-separation step ahead of solvent extraction. We supply the complete machinery — root cleaning, milling, starch separation, aqueous-ethanol extraction, filtration, resin purification, vacuum concentration, closed-loop solvent recovery, standardisation and spray drying — as a single turnkey system for the metabolic-support and functional-food nutraceutical industries.
Mechotech's Kudzu Root plant is engineered around two distinguishing features of Pueraria lobata root: its unusually high native starch content, which is separated out ahead of extraction to prevent gelatinisation and filtration fouling during downstream processing, and puerarin's C-glycoside chemical bond, which is markedly more hydrolysis-resistant than typical isoflavone glycosides and tolerates the controlled aqueous-ethanol extraction conditions well without significant aglycone conversion. A resin-adsorption purification stage concentrates the isoflavone fraction to reach the wide 20%-40% commercial grade band. Built in SS 316L with electropolished product-contact surfaces, closed-loop solvent recovery, and full batch documentation, each plant is delivered as a commissioned, turnkey system that holds the declared specification.

Manufacturing Process
Root Cleaning & Size Reduction
Dried Pueraria lobata root is authenticated, cleaned of soil and foreign matter, and milled to a uniform particle size ahead of starch separation and extraction.
Starch Separation
Kudzu root carries an unusually high native starch content compared to most nutraceutical roots; a dedicated separation stage removes the bulk starch fraction before solvent extraction, preventing gelatinisation and filter fouling downstream.
Aqueous-Ethanol Extraction
De-starched, milled root is charged into closed, jacketed SS 316L extractors and extracted with a controlled aqueous-ethanol solvent system across multiple cycles at regulated temperature, recovering the puerarin isoflavone C-glycoside fraction.
Filtration
The extract is clarified through a plate-and-frame filter press followed by cartridge polish filters, removing residual root fibre and fine starch carryover.
Resin-Adsorption Enrichment
The filtered extract is passed through a macroporous resin-adsorption column that concentrates the puerarin isoflavone fraction, enabling the extract to be standardised across the wide 20%-40% commercial grade band.
Vacuum Concentration & Solvent Recovery
The enriched extract is concentrated in a falling-film vacuum evaporator at controlled temperature, with ethanol recovered and recycled through the closed-loop system.
Standardisation
The concentrate is assayed by HPLC for puerarin content and adjusted to the declared 20%-40% specification before drying.
Spray Drying & Quality Control
The standardised concentrate is spray-dried to a free-flowing powder with controlled inlet/outlet temperature, then released after HPLC assay, residual-solvent, heavy-metal, microbial, and moisture testing with full certificate-of-analysis documentation.

Key Features
Dedicated Starch-Separation Stage
Kudzu root's unusually high native starch content is removed ahead of solvent extraction, preventing gelatinisation and filter fouling that a general-purpose root-extraction line would not be tuned to handle.
Resin-Enrichment for Wide-Range Standardisation
A macroporous resin-adsorption stage concentrates puerarin, letting the plant hit any point across the wide 20%-40% commercial grade band from the same base process.
SS 316L Construction
Electropolished SS 316L product-contact surfaces with CIP operation between batches.
Closed-Loop Solvent Recovery
Integrated condenser-return recovery reuses solvent between batches and reduces solvent loss.
Standardised 20%-40% Assay by HPLC
In-process and batch-release HPLC assay are used to check the finished powder against its declared specification for consistent, buyer-ready quality.
Scalable Batch Capacity
Plants are configured to requirement from pilot scale upward, with modular expansion.
