[ 1 ] - Amino acid and fatty acid profiles of materials recovered from Prussian carp, Carassius gibelio (Bloch, 1782), using acidic and basic solubilization/ precipitation technique

Isoelectric solubilization /precipitation (ISP) process was used to isolate protein from muscles of Prussian carp, Carassius gibelio (Bloch, 1782). Fish protein and lipid were recovered from whole gutted Prussian carp using acidic and basic isoelectric solubilization/precipitation followed by assaying amino acid and fatty acid profile. Essential amino acids content in acidic and basic pH treatm...

[ 2 ] - Effects of genistein on melanosis and microbial quality of Litopenaeus vannamei during ice storage

Utilization of genistein as a natural inhibitor was studied alone and in combination with conventional treatments on melanosis and microbial quality of fresh L. vannamei during 10 days ice storage. Treatments were as followed: A (dipping samples in distilled water), B (dipping in 1.25 % sodium metabisulphite solution), C (dipping in 0.01 % genistein + 2% glycerol solution), D (dipping in 0.1 % ...

[ 3 ] - Combined effects of Zataria multiflora boiss essential oil and nisin on the shelf-life of refrigerated rainbow trout

The effects of Z. multiflora essential oil (EO) and nisin (N) on fresh rainbow trout (Onchorynchus mykiss) fillets were studied during 18 days storage at 4 ºC. Bacteriological and organoleptical evaluation were performed on fresh rainbow trout as the functions of treatment and storage time. Treatments included the following: A (control), E1 (treated samples with 0.2 % EO), E2 (treated samples w...

[ 4 ] - Effect of different levels of dietary Betaine on growth performance, food efficiency and survival rate of pike perch (Sander lucioperca) fingerlings

A 6-week feeding experiments were carried out to determine the effects of different levels of dietary betaine on growth performance, food efficiency and survival rate of pike perch which has a critical period during transition feeding. Fingerlings of pike perch were fed with live food (treatment A), without betaine added to biomar (treatment B), 1% betaine added to biomar (treatment C) and 2% ...

[ 5 ] - Effects of frying by different frying oils on fatty acid profile of silver carp (Hypophthalmichthys molitrix)

The study aims to determine the influence of frying (shallow and deep) with olive, canola and sunflower oil on fatty acid composition of silver carp < /font>. Frying by olive oil and canola oil increased the monounsaturated fatty acids (MUFA) significantly (p < 0.05) that consequently decreased saturated fatty acids (SFA), polyunsaturated fatty acids (PUFA) and ω-3 fatty acids. Frying by sunfl...

[ 6 ] - The impact of lipid content, cooking and reheating on volatile compounds found in Narrow – barred Spanish mackerel (Scomberomorous commerson)

Effects of four cooking methods (microwave cooking, grilling, steaming and shallow fat frying) and reheating by microwave on volatile profile in S. commerson were evaluated. Thirty compounds were identified in GC-MS analysis of raw samples. The number of volatile compounds had increased to 36, 46, 45 and 45 compounds in microwave cooked, grilled, steamed and shallow fat fried samples, respectiv...

[ 7 ] - بررسی اثر آنتی‌اکسیدانی عصارة پوست پرتقال بر کیفیت فیلة کپور معمولی (Cyprinus carpio) هنگام نگهداری در یخچال (C°4)

به‌کاربردن عصاره‌های طبیعی، به‌منزلة یکی از منابع مناسب آنتی‌اکسیدانی، برای بهبود کیفیت ماهی در حال افزایش است. هدف این مطالعه بررسی تأثیرات آنتی‌اکسیدانی عصارة پوست پرتقال در کیفیت فیلة ماهی کپور معمولی هنگام نگهداری در یخچال (°C4) است. فیله‌ها با غلظت‌های صفر، 1 و 5درصد عصارة پوست پرتقال تیمار بسته‌بندی و در یخچال نگهداری شدند. ارزیابان شاخص‌های شیمیایی (pH، پراکسید (PV)، تیوباربیتوریک اسید (...
