As the name implies, nutritional yeast is more about boosting the nutrient content of your food than helping your bread rise. These cheesy-tasting flakes are rich in B vitamins and can be added to soups or sprinkled on popcorn for flavor. Vegans may use nutritional yeast to make cheese. As a dry ingredient, nutritional yeast may not spoil, but it is important to store properly to prevent contamination or loss of flavor.
Purchase nutritional yeast flakes in bulk from a reputable purveyor with a high turnover to ensure you get the freshest product. Or purchase a package with a use-by date that gives you enough time to use it up.
Buying in bulk allows you to purchase the amount you need, to limit storage time and space, and to save you money.
Mark your package of nutritional yeast with a date when you opened it.
Keep your opened nutritional yeast in a tightly sealed container and store in a cool, dark place.
Consider storing your nutritional yeast in the refrigerator, especially during the hot summer months.
Discard your open container of nutritional yeast after 1 year.
After harvesting, nutritional yeast is heated, dried and made into flakes or powder. The processing inactivates the yeast, which is why it cannot be used as a leavening agent for baking.
Using Nutritional Yeast
There are a number of ways you can include nutritional yeast in your diet to boost your B-vitamin intake.
