Fermentation Metabolite Postbiotics Survive Extrusion Better Than Live Probiotics
Kibble is extruded at 100 to 150 degrees Celsius, which kills live cultures, so pet food makers turn to yeast fermentation metabolites that stay active after heat and drying. Yeast Fermentation Metabolite Postbiotics grow about 14.0% a year from a small base, and gross margins run 44% to 60% against 26% to 36% for heat-inactivated whole yeast. The trend needs standardised metabolite content, spray drying, and dog and cat trial data. Supply contracts decide renewal. Delivery reliability decides supplier rankings. Margins follow sourcing discipline. Batch records protect future sales. Cost control separates leaders from followers.
