چکیده مقاله :
مقدمه: سبوس گندم به‌عنوان منبع غنی از فیبر رژیمی، پروتئین (6/14 درصد)، مواد معدنی (7 درصد)، اسید چرب غیراشباع (اسید اولئیک، لینولئیک و لینولنیک) (17 درصد) و انواع ویتامین‌ها شناخته می‌شود اما سبوس گندم دارای ویژگی‌های حسی نامطلوب نظیر طعم تلخ یا احساس دهانی شنی است. از طرف دیگر، غلظت برخی مواد نامطلوب سبوس گندم نظیر اسید فیتیک بالا می‌باشد. هدف از این پژوهش، بررسی تأثیر رطوبت خوراک ورودی و شرایط اکستروژن شامل دما و سرعت مارپیچ اکسترودر بر ویژگی‌های عملکردی، شیمیایی و تغذیه‌ای سبوس گندم می باشد. مواد و روش‌ها: به‌منظور اصلاح خصوصیات تغذیه‌ای و تکنولوژیکی سبوس گندم، تأثیر رطوبت خوراک ورودی به اکسترودر (18، 21 و 25 درصد) و شرایط اکستروژن شامل دما (°C 120، 160 و 200) و دور مارپیچ (rpm170، 235 و 300) بر خصوصیات عملکردی (اندیس جذب آب، اندیس جذب حلالیت در آب و اندیس جذب روغن)، شیمیایی (فیبر محلول و نامحلول) و تغذیه‌ای (اسید فیتیک) سبوس گندم فراوری‌شده مورد ارزیابی قرار گرفت. یافته‌ها: نتایج حاکی از آن بود بیشترین مقدار شاخص جذب آب و همچنین کمترین مقدار شاخص حلالیت در آب در رطوبت خوراک ورودی 25 درصد ، دمای°C 120 و دور مارپیچ rpm 170 به دست آمد. همچنین بیشترین مقدار شاخص حلالیت در آب و شاخص جذب روغن در رطوبت خوراک ورودی 18 درصد ، دمای°C 200 و دور مارپیچ rpm 300 مشاهده شد. بیشترین میزان کاهش اسید فیتیک در رطوبت خوراک ورودی 21درصد، دمای °C120 و دور مارپیچ 300 دور بر دقیقه مشاهده شد (mg/100g 09/3). نتیجه‌گیری: بررسی‌ها نشان داد فرایند اکستروژن سبب کاهش فیبر نامحلول به میزان 6 درصد و افزایش فیبر محلول به میزان 55 درصد می گردد.
Introduction: Wheat bran is a concentrated source of diatery fibre, protein, minerals, unsaturated fatty acids and vitamins. Existence of some technological and nutritional difficulties containing high amount of phytic acid and unappropriate sensory characteristics has coused limitation of its application in food formulation. In this study the effect of formulation and extrusion conditions containing feed moisture content, tempreture and screw speed were evaluated on chemical, functional and nutitional properties of texturized wheat bran. Materials and Methods: In order to improve the nutriotional and technological properties of wheat bran, the effects of different concentration of feed moisture content (18, 21 and 25%), tempreture (120, 160 and 200°C) and screw speed (170, 235 and 300 rpm) were examined on functional charactristics (water adsorbtion index; WAI, soluability index; SI and oil adsorbtion index; OAI, soluble and insoluble fiber), and the nutritional values (phytic acid) of processed wheat bran. Results: Based on results the maximum and minimum level of WAI and SI were obtained at 25% moisture content, 120°C and 170 rpm. However the maximum level of SI and OAI were demonstrated at 18% moisture content, 200°C and 300 rpm. The least Phytic acid content (3.09 mg/100g) was shown in 21% moisture content, 120°C and 300 rpm. Extrusion process had significant effect on enhancement of soluble fiber fraction (55%) and decreased the insoluble fiber (6%). Conclusion: The results indicated that, optimized condition of processing method could enhance the quality of processed wheat bran.
