چکیده

Investigations were carried out on quality changes in salted and dried horse mackerel (Megalaspis cordyla). Sun drying (T1) and mechanical drying (T2) process for fish cured with salt were selected for estimating their efficiency and effect during six months storage period. Sun dried fish showed mean value of moisture, protein, ash and fat as 27.83 %, 54.13 %, 12.95 %, 5.99 %, respectively, while mechanically dried fish exhibited 30.41 %, 52.93 %, 13.14 %, 5.80 % respectively. Other bio-chemical characteristics TMA-N, TVB-N, FFA and PV were 7.72 mg%, 24.45 mg%,6.44 %,8.26 m.equ./kg for T1 and 8.24 mg% , 22.19 mg % ,7.00 %, 78.58. m.equ./kg % for T2 respectively. TPC count were 1.77×10 and 1.91×10 log cfu/g, in T1 and T2 respectively. Sensory score of T2 was higher than T1 and it was statistically significant. The use of mechanical drier for drying of horse mackerel has the added advantage of superior quality and longer shelf life than Sun dried fishes.

QUALITY LOSS RELATED TO RANCIDITY DEVELOPMENT DURING HORSE MACKEREL (Trachurus trachurus) FROZEN STORAGE

The development of rancidity and its effect on quality loss was studied in frozen horse mackerel (Trachurus trachurus). For that, two different kinds of fish products (whole fish and fillets) were stored at a commercial frozen temperature (-20oC) for up to 12 months and were compared to samples stored at a much low temperature (-80oC). Analyses included: lipid hydrolysis (free fatty acid format...
