چکیده

میگو یکی از مهم‌ترین گونه‌های آبزیان در ایران می‌باشد. با توجه به روند افزایشی تولید میگو، تولید فرآورده‌هایی با ارزش ‏افزوده جدید بیش از پیش مورد نیاز است. هدف از پژوهش حاضر تولید یک فرآورده کنسرو شده جدید با استفاده از میگوی ‏سرتیز ‏Metapenaeus affinis)‎‏) بود. زمان حرارت‌دهی، غلظت نمک و غلظت سرکه هنگام آماده‌سازی میگو و همچنین ‏شاخص زمان استریل کردن بهینه‌سازی شد و اثرات آنها بر کیفیت این محصول مورد بررسی قرار گرفت. با افزایش غلظت نمک ‏و زمان استریل کردن وزن آبکش به‌طور معنی‌داری کاهش یافت (۰۵/۰>‏P‏) اما غلظت سرکه بر وزن آبکش میگوها تاثیری ‏نداشت (۰۵/۰<‏P‏). درصد شکستگی میگوهای کنسرو شده تحت تاثیر غلظت سرکه و زمان استریل کردن بود (۰۵/۰>‏P‏). با ‏افزایش زمان استریل کردن، شکستگی میگوها به طور معنی‌دار کاهش یافت (۰۵/۰>‏P‏)‏‎.‎‏ در حالی‌که با افزایش غلظت سرکه، ‏شکستگی میگوها به طور معنی‌دار نیز افزایش یافت (۰۵/۰>‏P‏). زمان حرارت دهی اولیه تأثیری بر میزان شکستگی میگوها ‏نداشت (۰۵/۰<‏P‏). اثر متقابل زمان استریل کردن و زمان استریل کردن میزان چربی میگوها را تغییر داد (۰۵/۰>‏P‏) اما سایر ‏عوامل تاثیر معنی‌داری بر این شاخص‌ نداشتند (۰۵/۰<‏P‏). بنابر نتایج بدست آمده ابتدا عامل زمان استریل کردن و سپس زمان ‏حرارت‌دهی اولیه بر کیفیت میگوهای کنسرو شده تأثیر قابل ملاحظه‌ای داشتند. ‏

چکیده [English]

Shrimp is one of the most important aquatic species in Iran. Considering the increasing trend in ‎shrimp production, development of new value added products is increasingly required. The aim of ‎the present study was to produce a new canned product from shrimp (Metapenaeus affinis) as the ‎raw material. Some variables including heating time, salt and vinegar concentrations as well as ‎sterilizing time were optimized and their effect on the drained weight, fracture percent and fat ‎content were determined. Drained weight was significantly decreased as a result of increasing the ‎salt concentration and sterilizing time (P<0.05), but vinegar concentration had no significant effect ‎on shrimp drained weight (P>0.05). Vinegar concentration and sterilization time had an important ‎effect on shrimp fracture (P<0.05). With increasing sterilizing time, shrimp fracture were ‎significantly decreased (P<0.05). However, with increasing vinegar concentration, shrimp fracture ‎significantly increased also (P<0.05). Heating time had no significant effect on shrimp fracture ‎‎(P>0.05). Interaction of sterilizing time and sterilizing time change shrimp fat content (P<0.05) but ‎other factor had no significant effect on this parameter (P>0.05). It was concluded that first ‎sterilization time and then heating process exert a great influence on the quality of the canned ‎product.‎
