產品說明
Ultrafiltered yeast extract produced by controlled autolysis of a selected yeast strain cultivated on a molasses-based medium. Ultrafiltration removes high-molecular-weight material, giving a highly soluble, low-endotoxin nutrient with a controlled dead-cell count. Supplies readily available amino acids, peptides, vitamins and essential trace elements with very low sodium chloride. Guaranteed non-GM and free of ingredients of animal origin.
