Abstract:

Irradiation is considered one of the most efficient technological processes for the reduction of microorganisms in food. It can be used to improve the safety of food products, and to extend their shelf lives. The aim of this study was to evaluate the effects of gamma irradiation and frozen storage as a combination process for improvement of shelf life. Fillets of Hemiramphus lutkei were treated with 0 (control), 1.5, 3.0, and 5.0 kGy of gamma irradiation and held frozen for 3 months. The control and irradiated samples were stored at -18oC and underwent microbial analysis, chemical characteristics and sensory evaluation at 1 month intervals. Microbial analysis indicated that irradiation and freezing storage had a significant effect (P < 0.05) on the reduction of microbial loads. There was no significant difference in sensory quality and chemical characteristics during freezing storage of H. lutkei. The combination of frozen storage plus irradiation resulted in greater overall reductions on microbial loads, extending shelf life of fish meat for commercial application.

Biography :

S. R. Sunith Shine was an Indian graduate who had his Master Course and Master of Philosophy in the field of ?Marine Biotechnology? in Center For Marine Science And Technology (C.M.S.T) Manonmaniam Sundaranar University and now he was pursuing his Ph.D. at Scott Christian College (Autonomous), Nagercoil Which is affiliated to Manonmaniam Sundaranar University, Tirunelveli. He obtained 4th rank in PG at university level. He attained post graduate scientific training from Bio-tech Consortia of India Limited (BCIL) Via Xpression Biotech, Bangalore. His doctoral programme focuses on the invention of newer technology which amends the use of Gamma rays in the role to perform preservation of Sea food and allied products. His areas of research interest include Post Harvest Technology, Microbial Security of Sea-food, Quality and risk assessment. Currently he was working as SRF in BRNS funded project on Radio-preservation Studies. He is a life member of Marine Biological Association of India, Kochi and Health physics Society, USA.
