چکیده
درخت بلوط در بسیاری از مناطق ایران به وفور یافت می­شود و معمولا میوه آن به هدر می­رود و یا به مصرف دام می­رسد. با توجه به ویژگی­های سلامت­زایی میوه بلوط، هدف از این پژوهش بررسی اثر آرد بلوط (جایگزین شده در سطوح 30-0% با آرد برنج، آرد و نشاسته ذرت) در قالب طرح آمیخته بر روی ویژگی های شیمیایی، تغذیه­ای، بافتی و حسی بیسکوئیت فاقد گلوتن برای بیماران سلیاکی می­باشد. نتایج حاصل نشان داد که میزان رطوبت، خاکستر، فیبر خام، کربوهیدرات، ظرفیت آنتی­اکسیدانی و محتوای فنل کل نمونه­های حاوی آرد بلوط در مقایسه با نمونه شاهد افزایش قابل توجهی داشت. با افزایش آرد بلوط میزان کالری نمونه­های بیسکویت فاقد گلوتن کاهش یافت. سفتی و انرژی نفوذ بیسکویت­ها با افزایش میزان جایگزینی آرد بلوط در فرمولاسیون افزایش یافت. با توجه به نتایج ارزیابی حسی، افزایش میزان آرد بلوط تا 20% مورد قبول بود ولی در سطوح بالای مصرفی، پذیرش کلی نمونه­های بیسکوئیت­ کاهش یافت. نتایج حاصله نشان داد که کاربرد آرد بلوط برای غنی سازی و افزایش ارزش تغذیه­ای محصولات پختی فاقد گلوتن میتواند مفید باشد.

چکیده English

Acorn tree is abundant in many parts of Iran and is usually wasted or used as animal feed. According to the numerous health effects of acorn, the aim of this research is to investigate the influence of acorn flour (substituted at levels of 0-30% with rice flour, corn flour and starch) as a mixture design on chemical, nutritional, textural and sensorial properties of gluten free biscuits for celiacs. The results showed that moisture, ash, crude fiber, carbohydrate, antioxidant capacity and total phenol of gluten free biscuits supplemented with acorn flour increased noticeably compared to control. Increasing the acorn flour decreased calorie value of gluten free biscuits. Hardness and penetration energy of samples increased with substitution of acorn flour in formulation. Sensory evaluation showed addition of acorn flour up to 20% was acceptable but total acceptance diminished at high levels of it. The obtained results signify that the application of acorn flour in gluten-free baking could be useful for fortification and increase of nutritional value.
