چکیده
امروزه درخواست برای تولید مواد غذایی فراسودمند افزایش یافته و صنعت غذا برای بهینه کردن ارزش تغذیه‌ای در کنار حفظ یا بهبود طعم محصول، بر طراحی مجدد مواد غذایی متمرکز شده است. هسته خرما به علت دارا بودن مواد مفید می‌تواند به عنوان منبع ارزان قیمت و با ارزش در تولید مواد غذایی فراسودمند مورد استفاده قرار گیرد. بدین منظور در این پژوهش پودر هسته خرما، در سطوح 0، 5، 10 ،15 درصد به فرمول ماکارونی پیکولی یا پنه ریگانه اضافه شد. ابتدا میزان چربی، رطوبت، پروتئین، خاکستر و فیبر آرد ماکارونی، آرد هسته خرما و محصول خشک بررسی شد. علاوه بر این آزمون‌های رنگ‌سنجی، بافت سنجی بر روی نمونه‌های خام و پخته، اندازه‌گیری ترکیبات فنولی، ویژگی‌های پخت و ارزیابی حسی بر روی طعم، رنگ و بافت محصول صورت گرفت. تجزیه و تحلیل داده‌ها نشان داد که مقدار پروتئین و رطوبت تیمارها با افزایش درصد آرد هسته خرما، کاهش یافته ولی مقدار چربی و خاکستر و فیبر نمونه‌ها افزایش یافت. علاوه بر این بررسی آزمون پخت نشان داد که با افزایش آرد هسته خرما افت پخت محصول بیشتر شده در حالی که زمان پخت محصول کاهش یافته است. ارزیابی بافت‌ و پذیرش کلی حاکی از عدم تفاوت معنی‌دار بین تیمارها بود. اما نتایج مربوط به تعیین ترکیبات فنولی روند افزایش این ترکیبات را با افزایش درصد آرد هسته خرما در تیمارها نشان داد. با توجه به ارزیابی مجموع نتایج تیمار حاوی ده درصد آرد هسته خرما به عنوان محصول بهینه معرفی شد.

چکیده English

Nowadays due to the interest of, asking for increased food production and the food industry focus on redesigning to optimize functional as well as maintain or improve the taste and nutritional value of the product.Palm kernel due to its significant amount of compounds can be used in beneficial food production as a cheap and functional source. In this study the nutritional benefits of palm kernel meal in 3 different levels (5, 10, 15%) was added to the formula Piccoli pasta and laboratory chemical, physical, and sensory quality was conducted for three times. Palm kernel powder-free pasta also was used as a reference sample. Then amount of this features were investigated in the final product. In addition, colorimetric tests, tissue analysis of raw and cooked samples, phenolic compounds measurement and sensory evaluation of taste, color and texture of the product was done. Data analysis shows that by increasing the amount of palm kernel flour, protein and moisture decreased, but fat, ash and fiber increased. In addition cooking analysis shows that Palm kernel meal volume loss increased while the cooking time is decreased comparing to traditional product.In the sensory evaluation there was no major difference and all three were in a same acceptable level. The results show that phenolic compounds increased with increasing palm kernel flour percentage. tissue analysis does not show any particular trend in the sample. According to the results replacement of ten percent of flour with palm kernel flour has the best result of checked ones.
