Abstract
Daenjang, a traditional Korean fermented soybean paste, was prepared by the fermentation with Aspergillus oryzae for 3 days, and then ripened with salt addition(13%) for 45 days. The changes of composition and fraction pattern of lipid in Daenjang during ripening period were studied. The total lipid of initial Daenjang(0 day ripening) consisted of 91.8% of neutral lipid, 7.1% of phospholipid and 1.1% of glycolipid, and minor changes of the composition were observed during the ripening. The contents of free fatty acid and esterified sterol in nonpolar lipid fraction were increased, however, no significant changes in polar lipid fraction were observed from the Daenjang in ripening. Linoleic, oleic, palmitic acids were the major fatty acyl moiety in the fractions of total lipid, triglyceride and free fatty acid, respectively. No significant changes in fatty acid compositions of the fractions were noted, although the saturated fatty acyl moiety of the fraction were increased a little during Daenjang ripening.
