چکیده

گوشت شتر ارزش تغذیه‌ای بالا و طعم مشابه با سایر منابع گوشت قرمز دارد. در این پژوهش به‌منظور بهبود ویژگی‌های بافتی تاثیر افزودن محلول‌های ماریناد (5 سطح)، زمان (2 سطح) و فرایند اولتراسیون (2 سطح) بر روی گوشت شتر بر پایه طرح کاملا تصادفی مورد بررسی قرار گرفت. قطعات گوشت به دو گروه تقسیم شد و یک گروه تحت فرایند اولتراسیون قرار گرفت. پنج گروه محلول ماریناد (عصاره زنجبیل 30%، عصاره زنجبیل 30%+ 5/0%، %1 و 5/1% اسیدسیتریک و آب مقطر (شاهد)) تهیه شد. قطعات گوشت در داخل محلول­ها در دمای C˚1±4 داخل کیسه‌های پلی اتیلنی خوابانده شد. پس از طی 24 و 48 ساعت خصوصیات فیزیکوشیمیایی، شاخص‌های رنگ (a*،b*  وL*)، بافت و ساختار میکروسکوپی نمونه‌ها مورد ارزیابی قرار گرفت. نمونه‌های ماریناد شده در عصاره زنجبیل 30% و 5/1% اسیدسیتریک، کمترین میزان pH (بعد از ماریناد و بعد از پخت) و بیشترین میزان افت پخت را نسبت به نمونه شاهد داشتند (05/0(P<. برای نمونه‌های گوشت ماریناد شده در عصاره زنجبیل 30%، بالاترین میزان شاخصa*، b* و L* نسبت به نمونه شاهد گزارش شد (05/0(P<. زمان و اولتراسیون در بهبود ویژگی‌های بافتی تاثیرگذار بودند. تصاویر میکروسکوپ الکترونی ایجاد تغییرات در ساختار داخلی پروتئین‌های گوشت و افزایش فضای خالی بین میوفیبریل‌ها پس از 48 ساعت را نشان داد. استفاده همزمان از عصاره زنجبیل، اسیدسیتریک و اولتراسوند گزینه مناسب‌تری جهت افزایش تردی گوشت نسبت به نمونه شاهد بود.
