Summary
Practical storage steps to help commercial users protect milk powder quality and maintain traceability.
Follow the product instructions first
No general storage rule replaces the manufacturer's instructions. The label, specification sheet or supplier documentation should be the primary reference because shelf life and storage conditions vary by product and packaging.
As general guidance, U.S. Dairy Export Council pages for Whole Milk Powder and Skim Milk Powder recommend cool, dry storage and use less than 27°C and relative humidity below 65% as reference conditions. These figures should not override the instructions for the product purchased.
Keep the area cool and dry
High humidity can worsen flowability, caking and physical quality. High temperatures can also accelerate quality deterioration, particularly in powders containing milkfat.
Handling after opening
Reduce exposure to air and moisture, reseal the liner or container, and use clean, dry scoops. If material is transferred to another container, preserve product name, batch/lot, opening date and traceability information.
Protect from odours and contamination
Avoid storing milk powder next to chemicals, strong-smelling materials or areas with elevated contamination risk. Apply appropriate housekeeping and pest-control procedures.
Use FIFO or FEFO
FIFO or FEFO helps prevent older inventory from being forgotten. Record lot usage where traceability is required.
