background: copper is a trace element vital to life, but the toxic effect of water pollution with it on fish is now exhibited. fish blood is susceptible to contamination-induced stress and its alternation due to the hematological and immunological parameters can be utilized as toxicity indices of xenobiotics. methods: in this study, juvenile species of silver carp with average weight of 200gr w...
in this study the effects of gamma irradiation and frozen storage on sensory, chemical and microbial quality of fish fillets was investigated. hypophtalmyctis molitrix were equally divided to 12 fillests, then these 12 fillets were equally arranged in 4 groups (1-4). one group considered as control with no treatment and the other 3 groups was treated by 0.75, 3 and 5 kgy of gamma irradiation...
abstract- in this study, texture profile analysis and a creep test were used to determine the textural quality attributes of fish protein isolates and conventional surimi. these isolates were made from raw materials obtained from filleting processes of silver carp (hypophthalmichthys molitrix) using acid and alkaline aided treatments. texture profile analysis was performed in order to obtain ha...
به منظور بهبود خواص فیلم های تولیدی بر پایه پروتئین میوفیبریل ماهی فیتوفاگ (hypophthalmichthys molitrix)، از 3 سطح نانوفیبرسلولز (1، 3 و 5%) استفاده شد. تیمار بهینه با ارزیابی خصوصیات مکانیکی، فیزیکی، نوری و همچنین آزمون میکروسکوپ الکترونی روبشی (sem) تعیین شد. افزودن نانوذرات سلولز تغییری در استحکام کششی ایجاد نکرد اما سبب کاهش کشسانی فیلم های تولیدی شد (05/0>p). خاصیت ممانعت فیلم ها در برابر ...
the effects of grape pomace extract (0, 2 and 4%) on quality and shelf life of silver carp ( hypophthalmicthys molitrix ) fillets during chill storage (4°c) were investigated. the control and the treated fillets were analyzed periodically for microbiological (tvc and ptc), chemical (tvb-n), and sensory characteristics. the results showed that grape pomace-treated samples have lower tvb-n (24.2 ...
Knowledge of fish diversity, population data and the stock size, and calculation of the amount of proper catch are essential for a wise and sustainable management of lakes. This research reports a study on fish populations in Dorudzan reservoir, Fars Province. The fish were sampled from three stations in the late Summer and mid Spring 2015, three days each, using nylon gill nets. The mean lengt...
