Abstract
The inclusion of phospholipid in the Maillard reaction between cysteine and ribose is known to modify the volatile aroma compounds produced. The contributions made to the headspace volatiles by 60 major products of this reaction have been compared for four different lipids and their effect on aroma quality noted.The results described demonstrate marked dissimilarities between the behaviour of the four lipids. The most noticeable distinction was between the effect of triglyceride and the three phospholipids, but there were also variations in the way that each of the three phospholipids participated in the Maillard reaction. As well as displaying marked differences in volatile products, reaction mixtures containing the four lipids possessed distinct aroma characteristics; the phospholipids containing phosphatidylethanolamine conferred the most meat‐like odour. These differences appear to be caused by the dissimilar fatty acid compositions and polar moieties. Thus this study underlines the importance of lipid interaction in the Maillard reaction for the formation of flavour.
