Can milk powder be stored in humid conditions?

Question

How does humidity affect your milk powder? Learn why it's so prone to clumping and the best ways to store it in a damp climate.

Answer 1

Milk powder should not be stored in humid conditions as it readily absorbs moisture, leading to clumping, spoilage, and a reduced shelf life. Store it in a cool, dry place in an airtight container.

Detailed Explanation:

Milk powder is hygroscopic, meaning it easily absorbs moisture from the air. High humidity provides ample moisture, which the milk powder will draw in. This absorbed moisture causes several problems:

1. Clumping: The powder particles stick together, forming hard clumps that are difficult to dissolve.

2. Spoilage: Moisture encourages the growth of bacteria and mold, leading to spoilage and making the milk powder unsafe to consume.

3. Reduced Shelf Life: Even without visible spoilage, absorbed moisture degrades the quality of the milk powder, affecting its flavor, texture, and nutritional value, significantly shortening its shelf life.

4. Caking: The powder can solidify into a hard, unusable mass.

To properly store milk powder, transfer it to an airtight container immediately after opening the original packaging. Store the container in a cool, dry place, such as a pantry or cupboard, away from direct sunlight and heat sources. Avoid storing it near sources of moisture, like the sink or dishwasher.

Pro Tip:

If you live in a particularly humid climate, consider adding a food-safe desiccant packet (like those found in vitamin bottles) to the airtight container to absorb any residual moisture. Ensure the desiccant packet doesn't come into direct contact with the milk powder.
