The shelf life of yeast extract depends on their physical form and storage conditions.

Yeast extract powder is very hygroscopic and must be stored in a dry area. If the product is exposed to high humidity (for example, if the original packaging is opened or damaged), there is a high risk of lump formation and significant deterioration in quality. Exposure to high temperatures for long times will lead to the formation of unwanted colour and flavour. Normal storage temperature should be below 25 degrees Celsius.

No refrigeration is necessary during normal transportation and clearance time at customs, because yeast extract quality will be preserved at temperatures up to 40 degrees Celsius for periods of up to eight weeks.

Yeast extracts are generally available in three different physical forms: liquid, paste and dry (as powder/granules). The average shelf life of liquids is 0.5 -1 year, pastes 1 - 2 years and dry forms 1.5 - 3 years, depending on the exact product type.
