چکیده
ماهی دودی از غذاهای آماذه مصرف به شمار می­رود که دارای ارزش غذایی فراوان و زمان ماندگاری طولانی است. از این رو مطالعه حاضر با هدف تهیه فرآورده دودی گرم ورقه­ای از فیله قره­برون پروشی دو ساله و ارزیابی ویژگی­های شیمیایی، میکروبی و حسی و تعیین زمان ماندگاری آن طی نگهداری در دمای یخچال انجام شد. نتایج نشان داد علیرغم تیمار شاهد در تیمارهای آزمایشی آلودگی با میکرواورگانیسم­ها و کپک و مخمر طی زمان نگهداری مشاهده نشد. ارزش غذایی در تیمارهای آزمایشی در مقایسه با شاهد افزایش معنی­دار نشان دادند (۰۵/۰p<). اسیدهای چرب لوریک، پالمیتیک، استیاریک، آراشیدونیک و دوکوزاهگزانوئیک اسید در تیمار دودی در مقایسه با تیمار شاهد افزایش نسبی داشتند. افزایش لینولئیک اسید و ایکوزاپنتانوئیک اسید در تیمار آزمایشی در مقایسه با شاهد معنی­دار بود (۰۵/۰p<). ویژگی­های میکروبی، شیمیایی، حسی و فیزیکی در تیمارهای آزمایشی در مقایسه با شاهد کاهش معنی­دار ارائه کردند (۰۵/۰p<). جمود نعشی ۳ ساعت بعد از صید شروع شده و به مدت ۴ ساعت ادامه یافت. تیمارهای شاهد و آزمایشی به ترتیب طی مدت زمان ۵ روز و شش ماه در یخچال کیفیت مطلوبی نشان دادند. با توجه به نتایج میکروبی، شیمیایی و حسی به دست آمده، فیله قره برون پروشی دودی تا پایان زمان نگهداری در یخچال از کیفیت مناسبی برخوردار بود و با توجه به این که تا کنون فرآورده آماده مصرف از فیله قره­برون پرورشی تهیه نشده این فرآورده جهت ایجاد تنوع در صنعت فرآوری آبزیان و عرضه محصول آماده مصرف به صنعت غذایی پیشنهاد می­گردد.

چکیده English

Smoked fish is one of the ready-to-eat foods that have high nutritional value and long shelf life. Therefore, the present study was performed to prepare a hot smoked laminate product from a two-year-old A. persicus and evaluate its chemical, microbial, sensory, and shelf life during refrigeration. Despite the control treatment, contamination to microorganisms, mold, and yeast was not observed in the experimental treatments during storage. Nutritional value in experimental treatments showed a significant increase compared to control (p<0/05). Loric, palmitic, stearic, arachidonic, and docosahexaenoic fatty acids had a relative increase in smoked treatment compared to control treatment. The increase of linoleic acid and eicosapentaenoic acid in the experimental treatment compared to the control was significant (p<0/05). Microbial, chemical, sensory, and physical properties in experimental treatments showed a significant decrease compared to the control (p<0/05). Rigor mortis was started for 3 hours after fishing and continued for 4 hours. The control treatments for 5 days and the experimental treatments during six months of refrigeration were of good quality. According to the obtained microbial, chemical, and sensory results, smoked A. persicus fillet had a good quality until the end of storage time in the refrigerator. It is recommended to diversify the aquatic processing industry and supply ready-to-eat products to the food industry.
