One of the important factors affecting the quality of bread is the quality of wheat flour protein called gluten. Gluten is the principal structure forming elements of most baked products, contributing to the elasticity, cohesiveness and viscosity characteristics of the dough. Thus, gluten substantially control the quality of wheat flour based products. Due to the importance of the role of gluten and the requirement for improving the flour quality, providing a simple, economical, and efficient method to improve the technical quality of wheat and bread is also an important and controversial challenge. Oxidizing agents are generally added to the wheat flour to accelerate the natural maturing and the flour becomes paler and yields dough with improved baking properties. However, increasing concern about their adverse effects has highlighted the need for the development of alternative oxidants. Atmospheric cold plasma (ACP) is an emerging advanced oxidation process which has recently drawn considerable interest from food scientists. Therefore, the objective of this study was to investigate the effect of non-thermal plasma treatments on the properties of wheat flour.   Materials and Methods: For this purpose, medium wheat flour was prepared from local silages and treated with ACP at 25V for 0, 2, 4, 6, 8 and 10 min. Chemical composition of flour samples (moisture content, protein and ash) were determined using standard methods (AACC, 2002). Color properties, damaged starch water soluble index, wet gluten, gluten index, zeleny and falling number values, water and oil absorption capacities, swelling power and solubility of wheat flour samples were also measured.   Results and Discussion: The results obtained from the measurement of properties for the treated and untreated flour showed that the water and oil absorptions, swelling power, and solubility, wet gluten, gluten index, Zeleny number and whiteness increased significantly with increasing time, while the pH, moisture content, b * and a * indices, were decreased by plasma treatment. In addition, the results showed that ACP conditions have a significant effect on functional properties that can be created floursand products with various characteristics. The results showed that plasma treatment affected the gluten index and wet gluten and techno functional properties of wheat flour. Overall, this study demonstrated that non-thermal plasma is a quick, efficient way to improve the technological properties of wheat flour, as an alternative to chemical oxidants    }, keywords = {Cold Plasma,Gluten,modification,Technological properties,Wheat flour}, title_fa = {ارزیابی تأثیر پلاسمای غیرحرارتی بر ویژگی‏های فیزیکوشیمیایی و عملکردی آرد گندم}, abstract_fa = {نظر به اهمیت نقش گلوتن در محصولات غله‏ای به‌ویژه نان و ضرورت اصلاح آرد، ارایه ‌یک‌ روش ساده، اقتصادی ‌و‌ کارا ‌به‌‌منظور بهبود کیفیت تکنولوژیکی گندم و نان تولیدی، ‌‌همچنان‌ یک‌ چالش‌ مهم ‌و بحث‌برانگیز ‌می‌باشد. در این پژوهش تأثیر تکنولوژی نوین پلاسمای غیرحرارتی‌ بر ‌بهبود ویژگی‏های فیزیکو‌شیمیایی و عملکردی ‌آرد ‌گندم بررسی شد. بدین منظور آرد ‌گندم‌ با‌ گلوتن متوسط تهیه و تحت تاثیر زمان اعمال تیمار ‌پلاسمای سرد (زمان صفر، 2، 4، 6، 8 و 10 دقیقه) قرار گرفتند. نتایج آزمون‏های فیزیکوشیمیایی نشان داد که با افزایش زمان اعمال تیمار پلاسما، مقدار pH و رطوبت کاهش اما مقدار گلوتن مرطوب، اندیس گلوتن و حجم رسوب زلنی افزایش یافت، اندازه‏گیری پارامترهای کیفی و عملکردی آرد گندم نشان داد پارامتر L*، درصد نشاسته آسیب‏دیده، اندیس حلالیت، ظرفیت جذب آب و روغن و قدرت تورم آرد گندم افزایش معنی‏داری (05/0>P) یافت، در حالی که پارامترهای a*، b* و عدد فالینگ کاهش معنی‏داری (05/0>P) پیدا کرد. بنابراین می‌توان از تکنولوژی نوین پلاسمای سرد به‌ویژه زمان 8 دقیقه در بهبود ویژگی‏های کیفی و عملکردی آرد گندم استفاده نمود.}, keywords_fa = {آرد,اصلاح,پلاسمای غیر حرارتی,گلوتن,گندم}, url = {https://ifstrj.um.ac.ir/article_39185.html}, eprint = {https://ifstrj.um.ac.ir/article_39185_342b13269f1a1981d55a9bea3e6cdded.pdf} }
