What is Primary-Grown Nutritional Yeast?
Primary-grown yeast is cultivated expressly for its nutritional components, rather than being the by-product of another industry such as brewing. Lesaffre derives its primary-grown nutritional yeast from pure strains of Saccharomyces cerevisiae grown on a purified nutrient source designed specifically for yeast. After the fermentation process is complete, the yeast is harvested, thoroughly washed, pasteurized and dried on roller drum dryers. The special growth medium and unique drying process are the secrets to the exceptional performance and flavor of RED STAR® Nutritional Yeast.
