چکیده
محصولات نانوایی که بخش عمده‌ای از صنایع غذایی فراوری شده را تشکیل می‌دهند، عموماً با آرد گندم تهیه شده و در هنگام اختلاط با آب شبکه گلوتن قوی ایجاد می‌کنند. اگرچه حضور پروتئین‌های گلوتنی در آرد گندم یک ویژگی منحصر بفرد است اما، جایگزینی آرد گندم با سایر دانه‌های غلات در فرآورده‌های نانوایی تا یک حد مشخص امکان‌پذیر است. در تحقیق حاضر سه ارزن با نام‌های ارزن ایتالیایی، ارزن مرواریدی و ارزن معمولی استفاده شدند. آرد ارزن استفاده شده به نسبت 10، 30، 50 و100 درصد جایگزین آرد گندم شد. . ویژگیهای بافتی، حسی و پارامترهای رنگی نمونه های کیک مورد بررسی قرار گرفت. نتایج نشان داد که افزایش در مقدار آرد ارزن در خمیر کیک خواص کارآیی پخت خمیر کیک را کاهش داد. میانگین ارتفاع کیک با افزایش مقدار آرد ارزن در خمیر کیک کاهش یافت. ارزن مرواریدی حجم کیک ارزنی بهتری را درمقایسه با دو کیک ارزن دیگر نشان داد. پیوستگی کیک ارزن با افزایش مقدار ارزن کاهش یافت و این تغییرات در پیوستگی برای هر سه آرد ارزن مشابه بود. ترکیب ارزن در خمیر کیک چسبندگی را کاهش داد. کیک‌های با ترکیب بیشتر ارزن سختی بیشتری داشتند. بطور کلی، ارزن مرواریدی کیک بهتری را در مقایسه با ارزن‌های ایتالیایی و معمولی تولید کرد. مقبولیت کلی کیک‌های ارزن در ارزیابی‌های حسی بیشتر بدست آمدند. با در نظر گرفتن کلیه خصوصیات مورد بررسی، نسبت 30 درصد جایگزینی آرد ارزن بهترین سطح جایگزینی پیشنهاد شد. نتایج این تحقیق در توسعه محصولات نانوایی حاوی ارزن بسیار مفید هستند.

چکیده English

Bakery products that contain main part of food process industries usually made with wheat flour and establish a stable gluten network when mixed with water. Although presence of gluten proteins in wheat flour is a unique property, but substituting of wheat flour with other cereal grains up to a certain limit is possible. In current research three different millet varieties namely Proso, Pearl and Foxtail millet were used. Millet flour was used in proportions of 10, 30, 50 and 100% in replacing wheat flour in a cake recipe. Sensorial properties, textural attributes and color indices were evaluated. Results showed that increase in millet concentration in cake formulation decreased the efficiency properties of cooking of dough. Cake height decreased with increase in millet concentration in dough. Pearl millet showed a better cake volume in comparing with the two other millets. Cake cohesiveness decreased with increase in millet substitution and these variations was the same for all varieties. Millet composition in dough decreased adhesiveness of the product. Cakes with higher millet composition showed higher hardness. Totally, Pearl millet produced better cakes in comparison with Proso and Foxtail millets. Total acceptability of millet cakes obtained higher scores at sensory analysis. Considering all characteristics used in current study, 30% substitution level suggested as the best substitution level. The results of current research are valuable at bakery products containing millets.
