Frequently asked questions
What is the difference between yeast extract and autolyzed yeast?
Autolyzed yeast retains cell walls (β-glucans, MOS). Yeast extract is the soluble fraction after cell-wall removal — higher free amino acids and nucleotides, no β-glucan.
Is yeast protein Halal?
Baker's and torula yeast on molasses substrate is widely certified Halal. Brewers' yeast requires ethanol removal certificate.
Which yeast product improves piglet performance most?
Autolyzed yeast at 1–2% in nursery diets consistently improves ADG 4–8% and reduces post-weaning diarrhea.
