Agar (Agar Agar) is a natural gelling and stabilizing agent derived from red algae (Gelidium spp.), used in pet food formulations for its strong gelling strength, thermal stability, and clean-label appeal. As a plant-derived hydrocolloid, it offers manufacturers a non-GMO alternative to synthetic stabilizers, well suited to premium and naturally positioned product lines.
Functional properties
Agar forms a firm, thermoreversible gel when hydrated and cooled, with a gelling strength of approximately 780 g/cm² at a 1.5% concentration — well above the typical specification threshold of 600 g/cm² — and a gel setting time of around 11 minutes. This makes it highly effective in wet and semi-moist pet food formats, including pâté, chunk-in-gravy, and jelly-style products, where consistent texture and structural integrity are formulation priorities.
Its stability across a broad pH range (typical solution pH of 7.1) and resistance to enzymatic breakdown make agar a reliable stabilizer under standard retort and thermal processing conditions used in canned and pouched pet food production.
Composition and specifications
Agar is supplied as off-white to pale yellow, translucent sheets, odorless with a mild, slightly seaweed-like taste and no off-flavor. Typical specifications include moisture content at or below 12% (typical result: 6.3%) and ash content at or below 6.0% (typical result: 3.1%), reflecting a high level of purity suitable for food and pet food additive use.
Heavy metal parameters (lead, arsenic, cadmium, and mercury) are controlled well within regulatory limits, and the product is manufactured under HACCP and GMP-controlled systems. It is certified non-GMO and does not contain allergenic ingredients under EU Regulation (EU) No. 1169/2011.
Formulation usability
Agar is typically included at low inclusion rates given its high gelling strength, with exact dosage depending on the desired gel firmness, product format, and interaction with other hydrocolloids or binders in the formulation. It disperses in aqueous systems upon heating and sets reliably on cooling, making it straightforward to integrate into standard wet pet food processing lines without specialized equipment.
Because gelling performance can be affected by mineral content and pH of the surrounding formulation, inclusion levels are generally established through trial batches specific to each product matrix.
Quality and compliance
Our agar is manufactured in compliance with Regulation (EC) No. 231/2012 on food additives and tested according to GB 1886.239 and EU Regulation (EC) No. 231/2012 standards. Each batch is supplied with a full Certificate of Analysis covering physical and chemical parameters, heavy metals, and microbiological testing (including Total Plate Count, yeasts and molds, E. coli, Salmonella, Staphylococcus aureus, and Pseudomonas aeruginosa), all conforming to specification.
The product is manufactured under HACCP, GMP, and ISO 22000-certified systems, with a shelf life of 24 months from the manufacture date when stored in a cool, dry place away from moisture and direct sunlight.
Sourcing and origin
Our agar is sourced from a specialized biotechnology manufacturer in Jiangsu, China, with established production infrastructure and a strong compliance track record across EU food additive regulations. Working with an established, certified manufacturer allows us to ensure batch-to-batch consistency in gelling performance and purity, backed by full documentation for every shipment.
Certificates of analysis, compliance documentation, and additional supporting information are available on request to support incoming quality assurance processes.
Market positioning
As consumer demand grows for naturally derived, recognizable ingredients on pet food labels, agar offers manufacturers a functional stabilizer that supports clean-label and premium positioning without compromising on processing performance. Its plant-based, non-GMO status also supports formulations targeting vegetarian, sustainability-focused, or naturally positioned product lines.
We supply agar in bulk quantities suited to industrial pet food production, with flexible contract terms based on expected volumes and delivery schedules. Product specifications, samples, and current pricing are available on request through our procurement team.
