Hibiscus Calyx Mucilage and Anthocyanin Extract

Extraction Technologies

Subcritical Water Extraction (SWE)Enzyme-Assisted Extraction (EAE)

Mechotech designs and manufactures turnkey extraction plants that process hibiscus calyces to recover mucilage and anthocyanins. We supply the machinery for the route selected after screening — raw-material preparation, extraction, separation, concentration or recovery, and drying or collection — configured to the target specification. Mechotech's technology screening assigns routes by target — mucilage: Subcritical Water (SWE) and Enzyme-Assisted (EAE); anthocyanins: Subcritical Water (SWE) and Enzyme-Assisted (EAE); the best-ranked route overall is Enzyme-Assisted Extraction (EAE) (high-priority screening, rank 24 of 100). The exact plant part / feed form is to be confirmed with the client.

For hibiscus calyces with mucilage and anthocyanins as the target, there are 2 candidate technologies: Subcritical Water Extraction (SWE) and Enzyme-Assisted Extraction (EAE). By route — Subcritical Water (SWE) for mucilage: high-priority screening, rank 29 of 100, pressurized water; Subcritical Water (SWE) for anthocyanins: relevant screening, rank 45 of 100, pressurized water; Enzyme-Assisted (EAE) for mucilage: high-priority screening, rank 24 of 100, water, enzyme and pH control; Enzyme-Assisted (EAE) for anthocyanins: exploratory screening, rank 86 of 100, water, enzyme and pH control. For the best-ranked route, Enzyme-Assisted (EAE), the screening flags: select cellulase/pectinase/protease by matrix; control enzyme cost and inactivation. These are screening candidates rather than guarantees: the final technology, operating parameters and plant configuration are established during process development and pilot validation. Product-contact parts are built in SS 316L with CIP-cleanable design, and automation is configured to the project.

Manufacturing Process

Each extraction method follows a different process — pick a method to see its steps.

Raw-Material Preparation

Hibiscus calyces are cleaned and size-reduced so mucilage and anthocyanins can be reached by the extraction medium; particle size and moisture are set during process development.

Vessel Loading & Pressurisation

Prepared hibiscus calyces and water are loaded into a pressure-rated extraction vessel.

Subcritical Water Extraction

Water held liquid under pressure at elevated temperature extracts mucilage and anthocyanins without an organic solvent; temperature and residence time are set to limit thermal degradation and hydrolysis.

Separation

Spent solids are separated by filtration or centrifugation and the extract is clarified before concentration.

Concentration

The clarified aqueous extract is concentrated under vacuum or by membrane systems where required; no organic solvent is used in this route.

Recovery, Standardisation & Drying

The mucilage and anthocyanins fraction is recovered from the concentrate by a route selected during process development and checked against the target specification; drying and storage behaviour are verified because phenolic targets can be sensitive to heat and oxidation.
