Do I Have to Refrigerate Nutritional Yeast?
Storing Tips for Freshness
Nutritional yeast, often a staple in vegan and vegetarian diets for its cheesy flavor and nutritional value, does not require refrigeration for safe storage. It is a deactivated yeast, distinct from the active yeasts used in baking and brewing, making it shelf-stable. The product typically maintains its quality for up to two years when stored correctly, making it a convenient and durable addition to plant-based pantries.
Proper storage of nutritional yeast involves keeping it in an airtight container away from moisture and heat. A cool, dry place, such as a pantry or cupboard, is ideal for maintaining its freshness and extending its shelf life. Although refrigeration is not a necessity, it may prolong the quality of the yeast by slowing down any potential deterioration processes.
The decision to refrigerate nutritional yeast is often based on personal preferences or climate considerations. In hotter, more humid environments, refrigeration can prevent clumping and preserve the yeast's characteristic texture and taste. For those who use nutritional yeast infrequently, refrigeration can help ensure that its flavor and nutritional benefits, including its B-vitamins and protein content, are retained for occasional use without the need for frequent replacements.
Understanding Nutritional Yeast
Nutritional yeast is a deactivated form of yeast often sold in flakes, granules, or powder. Unlike active yeast used in bread making, it does not have leavening abilities. Rather, it's prized for its savory, cheese-like flavor, making it a staple in many vegetarian and vegan diets.
