Should dairy powders be stored in glass jars?

Question

Are glass jars the best choice for storing dairy powders like milk powder? Learn why an airtight, opaque container is the ideal option.

Answer 1

Dairy powders should ideally be stored in airtight, opaque containers, and while glass jars can work, they must be dark-colored or stored in a dark place to protect the powder from light degradation.

Detailed Explanation:

Dairy powders, such as powdered milk, whey protein, or casein, are susceptible to degradation from moisture, light, and air. Proper storage is crucial to maintain their quality, flavor, and nutritional value. While glass jars offer an airtight seal and prevent moisture absorption, clear glass allows light to penetrate, which can lead to oxidation and loss of vitamins, particularly vitamin A and D. Therefore, if using glass jars, opt for dark-colored glass (amber or dark blue) or store the clear glass jars in a dark, cool pantry away from direct sunlight. Alternatively, consider using airtight containers made of opaque plastic or metal, which provide better protection against light. Ensure the container is thoroughly cleaned and dried before storing the dairy powder. A cool, dry environment is essential to prevent clumping and spoilage.

Pro Tip:

To further extend the shelf life of your dairy powders, consider adding a food-safe desiccant packet to the container to absorb any residual moisture. Replace the desiccant packet periodically to maintain its effectiveness.
