چکیده
سلیاک رایج ترین بیماری است که در اثر مصرف گلوتن بروز می‌کند. پروتئین گلوتن، مهم ‌ترین ترکیب در ایجاد بافت و در برگیرنده اجزائ فرمولاسیون محصولات صنایع پخت می باشد. این پروتئین در افراد مبتلا به بیماری سلیاک ایجاد حساسیت می کند و تنها راه درمان این بیماری استفاده از یک رژیم غذایی بدون گلوتن در تمام طول عمر فرد است . بنابراین استفاده از جایگزین‌های مناسب گلوتن در تهیه این دسته از محصولات امری ضروری است. از این رو هدف انجام این تحقیق بررسی تاثیر کنسانتره پروتئینی سبوس برنج درمقادیر 75/. ، 5/1، 25/2، 3 درصد به عنوان جایگزین گلوتن بر کیک اسفنجی می باشد. براساس نتایج بدست آمده، مشخص گردید که ویسکوزیته خمیر محصول نسبت به نمونه شاهد افزایش پیدا کرده است و افزودن پروتئین سبوس برنج تاثیر معنی‌داری بر میزان ویسکوزیته خمیر کیک اسفنجی دارد. همچنین اثر افزودن پروتئین با مقادیر ذکر شده باعث افزایش معنی داری در مقدار رطوبت و حجم مخصوص کیک شد. در نتایج حاصل از آنالیز سفتی بافت نمونه‌ ها، اختلاف معنی داری در مقایسه با نمونه شاهد وجود دارد و سفتی بافت تمامی نمونه ها طی دوره نگهداری افزایش یافت. براساس نتایج آزمون حسی، بالاترین امتیاز به نمونه حاوی 25/2 درصد پروتئین سبوس برنج تعلق گرفت و تیمار منتخب، تیمار T3 است.

چکیده English

Celiac disease is the most common disease caused by gluten consumption. Gluten protein, is the most important compound in creating tissue and contains components of the formulation of baking products. This protein causes allergies in people with celiac disease, and the only way to treat the disease is to eat a gluten-free diet for a lifetime.Therefore, the use of appropriate alternatives to gluten in the preparation of this category of products is essential. Therefore, the aim of this study was to investigate the effect of rice bran protein concentrate in the amount of 0.75. , 1.5, 2.25, 3 % as a gluten substitute for sponge cake. Based on the results, it was found that the viscosity of the product dough has increased compared to the control sample and the addition of rice bran protein has a significant effect on the density of sponge cake dough. Also, increasing the protein concentrate in mentioned amounts caused a significant increase in the moisture and specific volume of the cake. The results of tissue stiffness analysis of the samples showed that there is a significant difference compared to the control sample. According to the results, the highest score was given to the sample containing 2.25 rice bran protein and the selected treatment was T3 treatment.
