ABSTRACT

This research was conducted to know the seasonal variation in amino acid composition, fatty acid composition and anticancer capacity of the flesh of salt water prawn (Giant tiger prawn, Penaeus monodon) of the Bay of Bengal. For this purpose amino acid composition, fatty acid composition of the flesh of Penaeus monodon was estimated in winter, spring and summer season. Almost all amino acids were detected and estimated except tryptophane. Remarkable variation in amino acid content was observed during winter, spring and summer. Most noticeable seasonal variation was obtained in aspartic acid, threonine, glutamic acid, lysine, valine, isoleucine. In general the highest quantity of each amino acid was obtained in spring season compared to winter and summer. Essential amino acids and other amino acids were been detected and estimated in winter, spring and summer. Lipid of the flesh of Penaeus monodon contained both saturated and unsaturated fatty acids. Unsaturated fatty acids were 48.35% in winter, 60.64% in spring, only 11.6% in summer. In spring season unsaturated fatty acid percentage was highest (60.64%). There was a significant difference in the percentage of common unsaturated fatty acids and saturated fatty acids in winter, spring and summer. Most of the unsaturated fatty acids were long chain (C16 to C22). Some unsaturated fatty acids were polyunsaturated and some were n-3 polyunsaturated fatty acids. EPA and DHA have been detected in Penaeus monodon the percentage of which was highest in spring season. In winter season poly-phenol content was 20.3 μmol/100g DW and antioxidant capacity was 115.3 μg/g which indicate anticancer property of the flesh of the salt water prawn (Giant Tiger Prawn, Penaeus monodon).
