Common kilka were chilled during 1, 2, 3, 4 and 5 days to determine the influence of such storage times of fish over the quality of the final canned product. For this propose, common factors for determination of fish quality (moisture, total lipid, free fatty acid, peroxide, thiobarbituric acid and fatty acid profile) were selected and compared with the formation of fluorescence compounds in fi...
this study was carried out to evaluate the chemical compoition of alosa caspia and results compared with clupeonella engrauliformis which is a common fish catch among clupeonella and clupeidae spp in caspian sea . results showed that the amount of fat, protein, ash and dry matter in alosa was higher than clupeonella. the fatty acid composition showed that the epa was very high in alosa that sho...
the effect of salting by different salt composition on fatty acid profile studied in hot smoked black and caspian sea sprat, clupeonella cultriventris. after initial prepare activities, samples were exposed to brining process within two salt concentrations including of 100 % nacl (treatment 1 or t1) and 75 % nacl- 25 % kcl (treatment 2 or t2) under 15% brine solution for 3 hrs. the smoking proc...
The objective of the present study was to determine chemical composition and fatty acid profile of common Kilka ,Clupeonella cultriventris caspia, in the Caspian Sea. The chemical analysis revealed that the protein and lipid content of common Kilka were 15.05 and 6.5% of the fresh weight, and total MUFA, PUFA and SFA were found to be 37.00, 32.89 and 29.03% respectively. Palmitic acid (16:0) a...
روغن ماهی به دلیل داشتن مقادیر بالای اسیدهای چرب چند غیر اشباع، حساسیت اکسیداتیو بالایی داشته که سبب ایجاد طعمی نامطلوب و عدم تمایل به مصرف آن میشود. از این رو ریزپوشانی این ترکیب با هدف حفاظت آن در مقابل شرایط محیطی با استفاده از روش خشککن انجمادی مورد مطالعه قرار گرفت. به این منظور روغن ماهی کیلکا (Clupeonella cultriventris caspia) استخراج و پروفایل اسید چرب آن تعیین گردید. امولسیون روغن م...
تحقیق حاضر با هدف بررسی شاخصهای زیستی، برآورد وضعیت تولید مثل و پارامترهای رشد ماهی کیلکای معمولی ( (Clupeonella culltriventris طی سالهای 94 – 1393 در آبهای جنوب غربی دریای خزر در محدوده استان گیلان انجام گرفت. نمونه ها هر دو هفته یک باربه تعداد 30 قطعه، ماهی 6 بار و فصلی 18 بار به تعداد کل 1250 قطعه ، از بندر صیادی انزلی جمع آوری شدند این بندر بعنوان تخلیه گاه عمده کشتی های صیادی کیلکا گیر منط...
Background and purpose: Health quality of fish as an important source of protein for human has received increasing attention. This study, examined the concentrations of chromium, nickel, zinc, and copper in the muscle and skin tissues of two edible fish species of Alosa Caspica and Clupeonella cultiventris caspia in the southern Caspian Sea in 2013. Also, the risk assessment of consumption of t...
