Asam Gelugur (Garcinia atroviridis) Extract OEM: Standardisation, CoA and Halal Formats

Direct answer: For a brand owner specifying asam gelugur (Garcinia atroviridis) extract, the specification should fix a 100:1 extraction ratio, a 50–55% hydroxycitric acid (HCA) marker, moisture of 2–8%, pH 4–6, heavy-metal and microbial limits, and a certificate of analysis for every lot.

Asam gelugur is a sour tropical fruit of the Garcinia genus, traditionally sun-dried into slices and used as a souring agent in Malay cooking. As a manufactured ingredient it is a powder whose identity, marker content and limits are fixed by a written specification. This guide sets out what that specification should contain, how to read the certificate of analysis for each lot, and which finished formats a brand owner can commission from Bionutricia.

The reference specification for asam gelugur extract

Why HCA is the standardisation marker

Hydroxycitric acid is the characteristic organic acid of Garcinia fruits, and it is the marker this extract is standardised to, at 50–55% on the specification. The figure describes composition only. A brand owner writing its own product documents should use it as a compositional value and nothing more.

Ask that each certificate name the assay method used for the HCA result. A named method lets your own laboratory or an independent test house check the figure against the same specification.

Reading a certificate of analysis for this extract

A compliant certificate for each lot should carry the lot number, the HCA result against the 50–55% specification, moisture (2–8%), pH (4–6), particle size (more than 95% through 60 mesh), heavy-metal results for arsenic, lead, cadmium and mercury against the limits above, and microbial results for aerobic plate count, yeast and mould, coliforms and E. coli. Request the same parameter set on every lot so that batches can be compared over time.

Choosing the format for a powder extract

The specification stays the same whichever format a brand owner chooses, but the controls that protect it change. A powder sachet depends on moisture control, so the 2–8% moisture range and the sachet film are set together. A liquid format brings the pH range of 4–6 into the formula and needs a microbial control plan from the start. Bionutricia manufactures powder sachets (pillow, 3-side-seal or stick-pack), pouch beverages, chewable tablets and powder essence in a bottle or container, and the format is agreed for each product. The cost trade-off between a powder sachet and a pouch beverage for an asam gelugur formula is compared in our asam gelugur and collagen peptides format comparison.

Halal status and the documentation pack

Bionutricia’s manufacturing facility in Sungai Buloh, Selangor operates under JAKIM Halal certification alongside FSSC 22000, GMP, HACCP, US FDA registration and MeSTI. Asam gelugur extract is JAKIM halal certified. A brand owner’s halal file for a finished product should hold the ingredient documents, the specification and the certificate of analysis for each lot, so that every ingredient in the formula can be traced to its own documents.

Frequently asked questions

What does the HCA figure mean on a specification?

It is the hydroxycitric acid content the extract is standardised to, stated as 50–55% on the specification and confirmed on each certificate of analysis. It describes the composition of the powder only.

Why does the format change which specification controls matter most?

A powder sachet depends on moisture control, with the 2–8% moisture range set in the specification. A liquid format also needs the pH range of 4–6 and a microbial control plan, so the format decision changes which controls carry the most weight.

What should a certificate of analysis for this extract contain?

The lot number, the HCA result against the 50–55% specification, moisture, pH, particle size, heavy-metal results for arsenic, lead, cadmium and mercury, and microbial results, with the assay method named.

Is asam gelugur extract halal certified?

Yes. Asam gelugur extract is JAKIM halal certified, and Bionutricia’s manufacturing facility operates under JAKIM Halal certification.

Does Bionutricia sell the bulk extract?

Bulk raw-ingredient supply is handled through bionutriciaextract.com. Bionutricia.com covers finished OEM manufacturing for brand owners and distributors.
