Specialised peptones for demanding microbial applications.
Peptones are protein hydrolysates that provide nitrogen and amino acids as an essential energy source for micro-organisms. The source, composition, and free amino acid profile of a peptone directly influences microbial growth performance, making product consistency and specification reliability critical for diagnostic, fermentation and biopharma applications.
Tatua is the world's only peptone manufacturer with a fully integrated dairy protein supply chain. Our casein and whey are sourced directly from our own New Zealand milk supply – BSE/TSE-free, traceable, and produced under the same quality framework that governs our full product range. Non-GMO plant protein materials and enzymes are sourced internationally.
All products are FSSC 22000 certified and meet full Halal and Kosher requirements.
Dairy Peptones
Our casein peptones have been developed to match the chemical, compositional, and physical specifications of traditional Pancreatic Digest of Casein (tryptone) products, with Halal-certified alternatives available.
The dairy peptone range includes filtered and non-filtered options across a range of free amino acid profiles to support growth performance.

Plant Peptones
At Tatua, we apply our enzyme and downstream processing technology to non-dairy protein substrates, offering animal-free and allergen-free alternatives to traditional animal-derived peptones.
Tatua soy peptones are an established component of diagnostic media formulations – including TSA and TSB – and a proven performer in probiotic fermentation applications. Further plant-based protein sources are under review for potential future development.
