There are information gaps in the knowledge of the impacts of traditional techniques of fish preservation used to meet market demands even though there are growing concerns of the effects of these methods of preservation on product forms and qualities. In this study the effects of commonly used preservation techniques of hot smoking and sun-drying on the nutritional composition of Penaeus monodon were investigated. Proximate values varied significantly (P<0.05) except for protein the dominant constituent with an average value of 64%. Stearic acid varied significantly (P<0.05) with lowest values of 2.30% in smoked specimens. Oleic acid was the highest fatty acid thus the predominance of the monounsaturated fatty acids (MUFA) with smoked samples having predominant (P<0.05) values. ω-3/ ω-6 ratios of 7.76, 13.01 and 8.16 in fresh, smoked and sundried were in favour of the omega 3 with EPA (16.95±0.76-18.43±1.01%) being significantly higher (P<0.05) to the DHA (9.36±0.54-11.90±0.27%). Smoked forms had significantly higher values (P<0.05) of alanine, threonine, tyrosine and cysteine. Arginine and histidine were significantly raised (P<0.05) in sundried specimens. Isoleucine, methionine, aspartate, glycine and proline remained highest (P<0.05) in fresh samples. Lysine was limiting in smoked and sundried specimens. Smoked products offered healthiest advantage with the lowest values of saturated fatty acids (25.10%), index of atherogenicity (0.58), index of thrombogenicity (0.20) and bearing in mind goal of reduced coronary heart disease (CHD) in food consumption. This paper offers the first holistic work on nutritional evaluations of the three commonest forms for which Giant tiger shrimps are frequently consumed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
