Question 1

What is ProSaf® 632 and how is it different from other yeast products?

Accepted Answer

ProSaf® 632 is a highly purified, soluble yeast extract containing over 63% highly digestible protein, essential amino acids, small bioavailable peptides, nucleotides and B-group vitamins. Unlike traditional brewer's yeast or whole yeast products, ProSaf® 632 contains only the soluble yeast fraction, providing superior digestibility, palatability and nutrient availability. This makes it particularly valuable in aquaculture, specialised liquid feeds and premium pet food formulations where highly available protein and functional nutrition are essential.

Question 2

What are the benefits of using ProSaf® 632 in animal feeds?

Accepted Answer

ProSaf® 632 improves feed palatability, protein digestibility and nutrient utilisation through its highly digestible amino acids, peptides and natural glutamic acid content. It also supports intestinal development, microbiota diversity and immune function, helping improve feed efficiency, growth performance and animal resilience. These functional benefits make it an excellent ingredient where animal performance, gut health and consistent feed intake are priorities.

Question 3

Is ProSaf® 632 suitable for aquaculture diets?

Accepted Answer

Yes. ProSaf® 632 was specifically developed to support modern aquaculture formulations, particularly reduced fishmeal diets. Its highly soluble peptides, free amino acids and nucleotides enhance feed attractiveness, digestibility and nutrient absorption while helping maintain growth performance and immune status. Studies have demonstrated its value in shrimp and fish diets by supporting feed intake and enabling more sustainable, cost-effective protein formulations.

Question 4

Can ProSaf® 632 be used in premium pet food and specialised liquid diets?

Accepted Answer

Absolutely. Because ProSaf® 632 is highly soluble and rich in digestible peptides and essential amino acids, it is well suited to premium pet food, milk replacers, liquid feeding systems and specialised nutritional formulations. Its excellent palatability and readily available nutrients help improve feed acceptance while providing a concentrated, functional protein source for demanding nutritional applications.

Question 5

Why is ProSaf® 632 considered a sustainable alternative protein source?

Accepted Answer

ProSaf® 632 is produced from a proprietary Saccharomyces cerevisiae fermentation process, providing a consistent, high-quality protein ingredient that can partially replace less sustainable animal-derived proteins such as fishmeal or plasma. By supporting diet reformulation without compromising palatability, digestibility or animal performance, it helps manufacturers develop more sustainable feed solutions while maintaining productivity and nutritional value.
