چکیده

پنیر به‌عنوان یک محصول لبنی پرمصرف در دنیاست که دارای تنوع بسیار زیادی نیز می‌باشد. در بین انواع پنیر نوع فراپالایش آن در ایران مورد توجه بسیاری از مصرف‌کنندگان قرار دارد. لزوم تغییر طعم و تنوع در این محصول مدت‌هاست که مورد توجه بوده است. در این تحقیق نیز سعی شده تا با ایجاد طعم جدید جایگزینی برای چربی شیر معرفی شود. بر این اساس از دو ترکیب روغن کتان (FSO) (صفر-100 درصد) و کنسانتره پروتئین آب پنیر(WPC) (0-15درصد) در فرمولاسیون پنیر فراپالایش استفاده گردید. نتایج بهینه‌یابی فرمولاسیون پنیر سفید فراپالایش حاوی روغن بذر کتان وکنسانتره پروتئینی آب پنیر به جهت داشتن pH برابر با 82/4، آب‌اندازی 35/1 درصد، چربی 3/20 درصد، ماده خشک 45/32 درصد، شاخص سفتی 46/631 نیوتن، خاصیت ارتجاعی 94/0 میلی‌متر، امتیاز رنگ 2/3، بو 1/3، طعم 8/2، بافت 1/3 و پذیرش نهایی 11/3 شامل 01/96 درصد روغن کتان و 73/9 درصد کنسانتره پروتئینی آب پنیر با درجه تمایل 82/0 بود.
