Polyphenols Extraction Plants

Rose Hip Extract Powder

Mechotech designs and manufactures turnkey extraction plants for Rose Hip (Rosa canina), processing the dried fruit — the seed-bearing false fruit of the wild rose, not a leaf, root, or flower petal — into a powder standardised from 10% up to 90% Polyphenols by UV. Rose hip is genuinely one of the most concentrated natural sources of vitamin C found among fruits, alongside a rich polyphenol and flavonoid profile, which together underpin its long-standing antioxidant and joint-health reputation; the plant's declared standardisation here is polyphenols by UV, so vitamin C content is preserved through gentle processing and described qualitatively rather than assayed as the release specification. We supply the complete machinery — fruit-shell cleaning, deseeding and milling, aqueous-ethanol extraction, filtration, resin/membrane purification, vacuum concentration with solvent recovery, UV standardisation, and spray drying — to convert rose hip fruit into a consistent extract powder for nutraceutical, functional-food, and cosmetic buyers.

Mechotech's Rose Hip plant is engineered around two distinctive features of this fruit-based raw material: the fruit shell's naturally high native vitamin C and polyphenol content, which is genuinely more vitamin-C-rich than most other fruits used in botanical extraction and therefore benefits from lower processing temperatures than a root, bark, or seed line would require; and the unusually wide 10%-90% polyphenol specification range, which is achieved on the same base plant by adding an optional resin or membrane purification stage for higher-grade orders. The line uses deseeded fruit-shell milling, controlled low-temperature aqueous-ethanol extraction, staged filtration to manage pulp and fibre load, and vacuum concentration tuned to protect both polyphenols and residual vitamin C content. Built in SS 316L with electropolished product-contact surfaces, PLC-SCADA automation, and full batch documentation, each plant is delivered as a commissioned turnkey system engineered to the declared Polyphenols by UV specification.

Manufacturing Process

Fruit Cleaning & Deseeding

Dried rose hip fruit is cleaned of stem and calyx fragments, deseeded to isolate the vitamin-C- and polyphenol-rich outer shell, and tested for moisture — a raw-material handling step distinct from a leaf, root, or bark line, since rose hip is processed as a whole fruit shell rather than a fibrous plant part.

Size Reduction

Deseeded fruit shells are milled to a uniform particle size to expose the pulp and skin tissue where polyphenols and natural vitamin C are concentrated, ahead of extraction.

Low-Temperature Aqueous-Ethanol Extraction

Milled fruit material is charged into closed, jacketed SS 316L extractors and extracted with water or aqueous ethanol (40-70% v/v) at a moderated 40-60°C — kept lower than many leaf or bark extraction lines specifically to limit degradation of rose hip's naturally high native vitamin C content alongside its polyphenol fraction.

Filtration

The extract (miscella) is clarified through a plate-and-frame filter press followed by 1-5 micron cartridge polish filters, removing fruit pulp and fine solids before concentration.

Resin/Membrane Purification for High-Grade Output

For specifications above the standard 10% grade, the extract passes a macroporous resin or membrane purification stage that enriches the polyphenol fraction, allowing the same base plant to reach grades up to 90% by UV.

Vacuum Concentration

The filtered or purified miscella is concentrated in a falling-film evaporator at 45-60°C under vacuum — again kept moderate to protect residual vitamin C and polyphenol content — with ethanol recovered and recycled through a closed-loop system.

UV Standardisation

The concentrate is assayed by UV for total polyphenol content and adjusted to the specific declared grade ordered, from 10% up to 90%, before drying.

Spray Drying & Quality Control

The standardised concentrate is spray-dried under controlled inlet/outlet temperature to a free-flowing powder. Each batch undergoes UV assay, residual-solvent, heavy-metal, microbial, and moisture testing before release with full certificate-of-analysis documentation.

Key Features

GMP Hygienic SS 316L Construction
All product-contact surfaces are electropolished SS 316L, using GMP hygienic design for botanical extract manufacturing, with CIP operation between batches.
Wide Specification Range (10%-90% by UV)
An optional resin/membrane purification stage lets the same plant produce standard 10% grades through to enriched 90% polyphenol powders by UV, matching different buyer specifications.
Native Vitamin C & Polyphenol Protection
Closed low-temperature extraction and vacuum concentration at 40-60°C preserve rose hip's naturally concentrated native vitamin C alongside its polyphenol fraction, both of which underlie the fruit's antioxidant reputation.
Fruit-Specific Deseeding & Size Reduction
Dedicated deseeding equipment isolates the vitamin-C- and polyphenol-rich fruit shell from the seed before milling, a step unique to fruit-based raw material versus a leaf or root line.
Closed-Loop Solvent Recovery
Integrated condenser-distillation recovery returns ethanol for reuse each batch, reducing fresh-solvent consumption.
Scalable Batch Capacity
Plants are configured to requirement from pilot scale upward, with a modular design that allows expansion without replacing core equipment.

Frequently Asked Questions

What is rose hip extract powder and why is it commercially extracted?

Rose Hip Extract Powder is the concentrated, spray-dried extract of Rosa canina fruit, standardised for polyphenols from 10% up to 90% by UV. It delivers rose hip's antioxidant polyphenols, flavonoids, and natural vitamin C in a stable, consistently dosed form for nutraceutical, functional food, and cosmetic use, unlike raw fruit with naturally variable content.

Is rose hip really a notably rich source of vitamin C?

Yes — this is a well-documented, verifiable botanical fact. Rose hip fruit is genuinely one of the most concentrated natural sources of vitamin C among fruits, alongside its polyphenol and flavonoid profile. Mechotech's plant is standardised on total polyphenols by UV rather than a specific vitamin C percentage, so processing is deliberately kept gentle and low-temperature to preserve the fruit's native vitamin C content through to the finished powder, even though it is not the declared release specification.

Does Mechotech supply the complete machinery for rose hip extract powder?

Yes. Mechotech supplies the complete turnkey machinery — fruit cleaning, deseeding, milling, extraction vessels, filtration, resin/membrane purification, vacuum concentration with solvent recovery, and spray drying — engineered, fabricated at our Hyderabad facility, installed, and commissioned as a single integrated plant.

Why is rose hip processed as a deseeded fruit shell rather than a whole fruit or seed?

The polyphenol- and vitamin-C-rich tissue in rose hip is concentrated in the fruit's outer shell and pulp, not the seed. Deseeding before milling isolates this active-bearing tissue, a raw-material handling step distinct from a leaf, root, or bark botanical line.

How does Mechotech achieve high-grade 90% rose hip polyphenol powder?

Higher-grade specifications are reached by adding a macroporous resin or membrane purification stage after primary extraction to enrich the polyphenol fraction before concentration and spray drying, allowing the same base plant to produce 10% through 90% grades by UV.

What production capacities are available for the rose hip extract powder plant?

Mechotech manufactures rose hip extract powder plants from pilot systems for product development to commercial-scale plants. Capacity is selected based on fruit supply, confirmed buyer volume, and investment timeline, and we recommend a pilot plant to validate process parameters before scaling.

Which industries buy rose hip extract, and is the plant export-ready?

Antioxidant supplement, joint-health, functional-beverage, and cosmetic ingredient buyers are the principal markets for standardised rose hip polyphenol extract. Every Mechotech plant is built in electropolished SS 316L to FSSAI and GMP hygienic design norms, with full documentation for qualification, and we also engineer broader herbal extraction plants for buyers sourcing multiple botanicals from one facility.
