ملخص المقالة :
با توجه به اهمیت جایگاه روغن‌های خوراکی در رژیم غذایی و افزایش تقاضا برای استفاده از روغن‌های خام و فرآیند نشده در این تحقیق ویژگی‌های شیمیایی روغن‌های حاصل از روش استخراج پرس سرد و استخراج با حلال سه واریته مختلف دانه کنجد شامل ترکیب اسیدهای چرب، مقادیر کلروفیل، بتاکاروتن، استرول، توکوفرول و آفلاتوکسین با روغن تصفیه شده مورد مقایسه قرار گرفت. عدد پراکسید نیز طی دو شرایط تسریع شده اکسیداسیون حرارتی و نوری تعیین شد. نتایج نشان داد بازده روش استخراج با حلال (13/58 درصد) بیش از روش پرس سرد بوده و اسیدهای چرب غالب در نمونه‌های روغن کنجد شامل اسیدهای اولئیک و لینولئیک می‌باشند. استرول تام در روغن پرس سرد (435/5367 میلی گرم بر کیلوگرم) بیش از روغن استخراج شده با حلال و روغن تصفیه شده بوده است. طی فرآیند تصفیه میزان کلروفیل و کاروتنوئید روغن کاهش یافت (P <0.05). بیش‌ترین و کم‌ترین میزان توکوفرول کل به‌ترتیب مربوط به‌روش استخراج با حلال و روغن تصفیه شده معادل 18/759 و 14/437 میلی‌گرم بر کیلوگرم بود. عدد پراکسید در شرایط تسریع شده نوری و دمایی باگذشت زمان افزایش یافت و تأثیر نور بر روند افزایش عدد پراکسید بیش از دما بوده است. علیرغم وجود مقدار ناچیز (12/0 – 08/0 ppb) آفلاتوکسین کل در دانه، میزان آن در نمونه‌های روغن استخراج شده زیر حد قابل‌تشخیص دستگاه (ppb 01/0) بود. لذا با وجود خواص تغذیه ای بالاتر روغن های پرس سرد نسبت به نوع تصفیه شده، این روغن ها قابلیت ماندگاری پایین تری نسبت به نوع تصفیه شده دارند.
