Establishment of Fatty Acid Profile and Comparative Analysis of Volatile Substances in Regular and DHA-Biofortified Raw Milk
Source abstract
Abstract
This study aimed to establish fatty acid profiles of regular raw milk and docosahexaenoic acid (DHA)-biofortified raw milk and to compare the volatile substance composition of the two types of raw milk. The fatty acid composition of the two types of raw milk was analyzed by gas chromatography–mass spectrometry (GC). The results revealed the absence of C15:1, C17:1, C18:2, C22:1, and C24:1 in both types of raw milk, while C20:3 and C22:6 were exclusively found in DHA-biofortified raw milk. The fatty acid levels generally followed a pattern of initial increase and subsequent decrease during lactation, with higher concentrations of short- and medium-chain fatty acids being observed in regular raw milk. The C16:0, C18:3, C20:3, and C20:5 contents in the two types of raw milk varied significantly at different lactation stages. The gas chromatography–mass spectrometry (GC-MS) analysis of the volatile substances revealed the presence of aldehydes, ketones, esters, acids, and sulfur-containing compounds. The volatile substance content in the DHA-biofortified raw milk was generally higher than that in the regular raw milk, which was attributed to the elevated levels of unsaturated fatty acids in biofortified DHA raw milk.
