Prof. William Dalton, Ph.D.Proper storage enhances the 2 years of shelf life for nutritional yeast and helps preserve its delicate flavors and nutrients. I have been able to save batches for years by using an airtight method. Additionally, exposure to moisture, light, or heat will quickly compromise the quality. And if yeast is improperly stored, it loses its effectiveness within 6 months, resulting in clumps and unpleasant flavors.
Container Selection
- Glass jars with silicone seals prevent moisture intrusion
- Metal tins block light but require desiccant packets
- Avoid plastic bags which allow humidity penetration
- Never use paper packaging due to permeability
Environmental Control
- Maintain consistent 50-70°F (10-21°C) temperatures
- Relative humidity below 50% prevents clumping
- Dark locations like pantries protect from light damage
- Avoid placement near ovens or dishwashers
Preservation Techniques
- Refrigeration extends freshness but isn't mandatory
- Freezing preserves nutrients for 3+ years
- Portion large quantities into smaller containers
- Include oxygen absorbers for long-term storage
Prevent moisture damage that can result in irreversible clumping. Silica gel packets are an excellent way to absorb ambient moisture. Examine seals for integrity at least once a month. I replace desiccants every three months. Never open containers in humid areas, such as kitchens, while they are steaming. Always use dry utensils when scooping yeast.
Check frequently for signs of spoilage. Clumping indicates moisture has invaded, and it must be transferred to be saved. Discoloration means the products are oxidized with a loss of nourishment. Yellow flakes means the B vitamins have broken down. Odors of dampness mean immediate and necessary disposal. I conduct monthly visual inspections and rotate stock.
