چکیده | ||
تشخیص و تعیین خواص فیزیکوشیمیایی، ترکیبات موثره روغن زیتون و پایداری اکسایشی آن طی انبارداری از اهمیت خاصی برخوردار است، لذا در این پژوهش برخی از ویژگیهای روغن زیتون فرابکر حاصل از میوه زیتون رقم کرونائیکی طی دو سال انبارداری در دمای 4 درجه سلسیوس و در تاریکی بررسی شد. نتایج نشان داد که عدد اسیدیته، عدد پراکسید، عدد آنیزیدین و مقدار موم افزایش و میزان ترکیبات غیرقابل صابونی، استرول کل و فنول کل و نیز فعالیت آنتیاکسیدانی کاهش یافت. در تعداد کربن معادل تریآسیلگلیسرولها تغییر حائز اهمیتی مشاهده نشد (05/0 | ||
