Microbiological and Chemical Quality Assessment of Six Fish Species of Bangladesh during Freeze Storage
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 3
Abstract
The following six Bangladeshi fish species, Rui (Labeo rohita), Catla (Catla catla), Tilapia (Oreochromis mossambicus), Pangas (Pangasianodon hypophthalmus), Mrigal (Cirrhinus cirrhosus) and Carfu (Cyprinus carpio ) were assessed for quality changes for 30 days of freezing(-10°C) storage. The bacteriological quality, chemical changes of fish fats of these six species of cultured ponds and different wholesale & retail markets of Dhaka city were analysed. Microbial load was highest in local retail markets samples and were lowest in cultured ponds samples. In total, 54 samples were analysed and they differ from species to species and with environment. For all sample, TVBC ranged from 2.75x105 to 6.29x106 cfu/g in first days. But they raised upto 9.96x108 cfu/g for local retail market samples in 30th day. We extracted fish fats of this six species and examined 5 days interval upto 30 days and found that FFA and POV increased & Iodine value decrease day by day and with environmental condition.
