Composition of Free Sugars Organic Acids and Free Amino Acids in Loquat Flesh
초록
For the investigation of major taste components in loquat(Eiobotrya japonica) flesh its conte-nts and compositions of free sugars organic aicds and free amino acids were analyzed Major free sugars of the fully ripened loquat were fructose glucose and sucrose and their contents were 3,71, 3.42 and 0.46%(w/w) respectively. The content of total sugar 13.7% was 2 times higher than that of the unripe fruit. The content of total organic acid was about 0.2% (w/w) and major organic acids were malic acid -89mg% formic acid -32mg% and oxalic acid -26%mg% Thirteen kinds of free amino acids from the fully ripened loquat were confirmed. Major free amino acids were aspartic acid valine glutamic acid serine alanine and histidine and their contents were in the range of 18-30mg%.
