Influence of storage on physicochemical properties of spray-dried infant milk formula powders containing different whey protein-to-casein ratios

Key Points

• Storage duration influences the physicochemical properties of the infant formula powders significantly, and alters texture and stability.
• The analysis found that increased whey protein ratios led to notable changes in moisture content and solubility.
• Observational analysis focused on the impact of storage on different whey protein-to-casein ratios in the infant formulas.
• The findings highlight the importance of storage conditions, suggesting the need for careful handling of these formulas.
