Plant Peptones: Rice, Pea, Wheat, Guar, Mung Bean, Malt

Plant nitrogen sources other than soy. Rice and pea are free of soy and gluten, an option for low-allergen formulations; wheat and malt carry gluten but offer a different amino acid profile; guar, mung bean, corn and potato bring their own peptide and flavour characteristics.

Plant peptones are enzymatic hydrolysates of various plant proteins. The amino acid profile varies widely by source: pea and rice offer a better lysine and arginine balance, wheat and malt are rich in glutamine, while guar and mung bean are often used where a specific flavour or low salt is needed. With no animal and no soy content, this class is increasingly used in probiotics, plant-based foods and serum-free cell culture media.

When choosing a plant peptone, allergens are usually the first consideration: rice, pea, mung bean, guar, corn and potato are not regulated major allergens; wheat and malt contain gluten. Next come clarity and salt: liquid products and cell culture need a clear-solution grade, and low-salt formulations should check ash and sodium chloride on the specification sheet.

This page lists the rice, pea, wheat, guar, mung bean, corn, potato and malt products supplied by STBIO MEDIA. Some are blends with yeast, which the tags indicate.

How to choose

  • To avoid both soy and gluten: choose rice or pea peptone.
  • Probiotic, plant-based or vegan claims: the whole class is animal-free; narrow down by allergen and certification.
  • Serum-free supplements for cell culture: look first at plant hydrolysates labelled clear solution and low endotoxin, and ask for the specification sheet.
  • Brewing or yeast fermentation: malt-derived nitrogen is closest to the process environment.

Frequently asked questions

01Which plant peptones are allergen-free?

Products from rice, pea, mung bean, guar, corn and potato are not regulated major allergens; wheat and malt contain gluten, and soy is listed separately. Always confirm with the allergen field on the product page and specification sheet, as some blends contain yeast or other ingredients.

02Can plant peptones be used in cell culture?

Yes. Plant protein hydrolysates are a common supplement for reducing serum, and published work shows benefits in HEK293, Vero and mesenchymal stromal cells. For cell culture, pay particular attention to clarity, endotoxin and batch consistency; request a sample and specification sheet first.
