Ultra-Filtered & Autolysate Yeast Extracts

Kerry's yeast specialties and yeast autolysates ensure optimal performance in the growth of a broad range of microorganisms. They provide essential peptides, amino acids, vitamins and minerals, as well as a complex mixture of yeast-derived metabolites.

Derived from primary-grown baker’s yeast and propagated aerobically under controlled, reproducible conditions, they offer a distinct performance and consistency advantage over secondary or brewer’s yeast extracts. All of our yeast specialties and yeast autolysates are produced in our yeast fermentation plant in Menstrie, Scotland, which uses only animal-free raw materials and provides a Kosher Pareve and Halal production range. Products can be supplied as liquid, paste or non-dusting powder, depending on your requirements.
