چکیده

در سال­های اخیر، اهمیت غنی­سازی نان گندم با بستره­های تخمیری و منابع گیاهی، بیشتر مشخص گردیده است. در این پژوهش، تأثیر استفاده توأم از تخمیر کنترل شده جو دوسر و پودر عناب بر بافت و فعالیت آنتی­اکسیدانی نان گندم تولیدی مورد بررسی قرار گرفت. بر این اساس، سفتی بافت، تخلخل، حجم مخصوص، پذیرش کلی و فعالیت آنتی­اکسیدانی در نان­های گندم حاوی تخمیر کنترل شده جو دوسر، پودر عناب و مخلوط آن­ها در مقایسه با نمونه شاهد ارزیابی شد. میزان تخلخل در تمام نان­های تولیدی به شکل معنی­داری (05/0p <) از نمونه شاهد بیشتر بود. با افزودن تخمیر کنترل شده جو دوسر و پودر عناب، تفاوت معنی­داری در میزان پذیرش کلی نان­های تولیدی مشاهده نگردید. نان حاوی مخلوط تخمیر کنترل شده جو دوسر و پودر عناب، دارای بیشترین سفتی بافت و کمترین مقدار حجم مخصوص بود. فعالیت آنتی­اکسیدانی نیز در تمام نمونه­ها به شکل معنی­داری از نمونه شاهد بیشتر بود و نان­ گندم حاوی مخلوط تخمیر کنترل شده جو دوسر و پودر عناب با 52/90 درصد بالاترین میزان فعالیت آنتی­اکسیدانی را به خود اختصاص داد. بر اساس نتایج به دست آمده، استفاده از فرمولاسیون بهینه حاوی تخمیر کنترل شده جو دوسر و پودر عناب جهت تولید نان­ گندم غنی شده می­تواند نتایج مطلوبی را به همراه داشته باشد.
