Abstract
This study was conducted to investigate the effect of various combinations of sugars, amino acids, and fatty acids (oleic/ linoleic aicds) on volatile compounds of low-fat sausages (LFSs) to have similar characteristics to those with regular-fat counterparts (RFC). The addition of glucose or fructose alone in LFC increased the concentrations of myristicine, pentadecanal and octadecanal, as compared to RFC. In addition, LFSs containing lysine alone had higher concentration of myristicine, as compared to those with RFC. Without the addition of both oleic and linoleic acids, LFS containing glucose in combination with various amino acids, such as alanine, aspartic acid, cysteine, and lysine, had higher concentration of myristicine, as compared to RFC. Furthermore, myristicine content (ppm) of LFSs was different from those of RFC, regardless of the concentration of lysine in combined with glucose or fructose. LFSs containing oleic and linoleic acids with the combination of glucose/glycine or glucose/alanine had the most similar volatile compounds to those of RFC. These results indicated that volatile compounds isolated from smoked LFSs containing sodium caseinate as a fat replacer and the multiple combinations of sugar, amino acids, and fatty acids had the most similar volatile compounds to those of RFC.
