Overview
Pea Peptone SB is a plant- and yeast-based peptone produced through controlled enzymatic hydrolysis, delivering a peptide-rich profile optimized for rapid uptake and metabolic availability. Formulated from pea and yeast sources, it is free from common allergens, making it suitable for clean-label and dietary-sensitive applications. Its balanced composition — abundant in short-chain peptides, free amino acids, B-group vitamins, nucleotides, and essential minerals — supports robust cell growth and high fermentation performance across a wide range of microbial and cell culture systems.
Choosing a plant peptone by raw material
Plant peptones contain no animal components, which suits Halal, vegetarian and animal-free formulations; raw materials differ in amino acid profile and allergens. Rice peptone carries a low allergen risk and suits gluten-free and hypoallergenic formulations. Pea and mung bean peptones contain no soy or gluten and often replace soy peptone. Wheat peptone is naturally rich in glutamine but contains gluten. Guar peptone is common in industrial fermentation. Plant peptone blends combine several raw materials designed for a given use. To avoid a particular allergen, check the allergen field on the product page first.

Food grade versus laboratory grade
Most culture media suppliers use laboratory-grade raw materials, which are held to lower standards for heavy metal residues, microbial contamination control, and traceability. That is adequate for pure research but not for applications with stricter raw-material requirements. STBIO manufactures with food-grade raw materials throughout, in a facility certified to ISO 22000 food safety management.
- Food microbiology laboratories working to ISO 17025 or equivalent requirements
- Biotech manufacturers exporting fermentation products and needing full raw-material traceability
- Organisations with ESG or compliance audit requirements across their supply chain
- Companies sourcing both Halal and non-Halal products who need one consistent material grade
Frequently asked questions
01Can plant peptones fully replace animal peptones?
In most fermentation and cell culture it can, but it needs verifying. Animal peptones have an amino acid profile closer to microbial needs, and a single plant source may run low in some amino acids; the usual approach is to combine two plant peptones (pea with rice, for example) or use a plant peptone blend. Trial and compare growth curves and product.
02Which organisms is it suitable for?
Yeast. See the cultural response table and the specification sheet.
03Is it free of animal-derived components?
Yes. This product is animal-origin-free, suitable for animal-free formulations and Halal requirements; a declaration is available on request.
04Is the raw material non-GMO?
Yes. The raw material is non-GMO; the supplier declaration can be provided with the COA.
05Can it be used for food-grade applications?
Yes. It is made from food-grade raw materials in an ISO 22000 certified facility and is suitable for culturing starters for fermented products that are consumed directly.
06How do I request a bulk quotation, and can you provide a COA?
Yes. This product is available in 500 g, 5 kg, 25 kg. Tell us your application and volume when requesting a quotation; we reply within one working day and can supply the COA, specification sheet, and technical data sheet.
