چکیده انگلیسی
The evolution of the volatile compounds propanal, pentanal and hexanal, and fatty acid profiles were examined in 20 infant formula (IF) milk powders during storage at 25 °C for 70 days after their packaging was opened. Few changes were observed in the fatty acid content during storage, but significant losses were found in C18:2 n − 6 and C18:3 n − 3 for some formulae. All three volatiles increased during storage in all formulae, confirming oxidative stability decreases once packets were opened. Significant correlation (p < 0.05) was detected between hexanal content and oxidation of n − 6 PUFA, specifically C18:2 n − 6 losses, and between propanal content and oxidation of n − 3 PUFA, specifically from C18:3 n − 3 losses.
