[ 1 ] - PET/Mica nanocomposites for food packaging: Crystallization behavior and mechanical properties
Nowadays polymer nanocomposites have introduced as a new class of food packaging materials due to their enhanced mechanical, thermal, and barrier properties. In this study PET nano composites were prepared by melt blending of poly (ethylene terephthalate) pellets and mica nanoparticles. The morphology of PET/mica nanocomposites was characterized by X-ray diffraction and transmission electron mi...
[ 2 ] - Effect of extraction rate on rheological properties of wheat flour
The effect of different extraction rates (64%, 82% and 90%) of wheat flour on the rheological properties of the wheat flour dough was investigated. A complete study of the rheological behavior of the wheat flour dough was performed by using three different instruments namely alveograph, extensograph, and farinograph. The correlation coefficient among the various parameters of applied methods wa...
[ 3 ] - بررسی ارتباط طیف FTIR و ویژگیهای پنیر سفید ایرانی کم‌چرب اصلاح‌شده با صمغ کتیرا گونه Astragalus Parrowianus
سابقه و هدف: به سبب ویژگیهای حسی و فیزیکی ضعیف در پنیرهای کم‌چرب، استفاده از جایگزین‌های چربی در این نوع پنیرها پیشنهاد می‌شود. اﺛﺮ ﭘﻠﯽﺳﺎﮐﺎریﺪﻫﺎ به عنوان جایگزین چربی با هدف ﺑﻬﺒﻮد ویﮋﮔﯽﻫﺎی ﭘﻨﯿﺮ ﮐﻢ ﭼﺮب، ﺗﻮﺳﻂ ﻣﺤﻘﻘﺎن ﻣﺘﻌﺪدی ﻣﻮرد ﻣﻄﺎﻟﻌﻪ ﻗﺮار ﮔﺮﻓﺘﻪ اﺳﺖ. در این پژوهش، برای بهبود ویژگیهای پنیر سفید ایرانی کم‌چرب، صمغ کتیرا گونه (Astragalus Parrowianus) (در دو سطح 05/0 درصد و 1/0 درصد) – درصدها به...
[ 4 ] - اثر دما و زمان نگهداری و ویژگی لاک قوطی بسته‌بندی بر مهاجرت آلومینیوم به درون آبجوی بدون الکل و ویژگیهای حسی آن
سابقه و هدف: با‌توجه به مضرات آلومینیوم و افزایش چشمگیر مصرف آبجوی بدون الکل بسته‌بندی شده در قوطی‌های آلومینیومی، لزوم جمع‌آوری و انتشار اطلاعات در مورد مقایسه کارایی پوشش‌های قوطی و میزان مهاجرت آلومینیوم از بسته‌بندی طی دوره نگهداری احساس می‌شود. هدف از این مطالعه بررسی اثر دما و زمان نگهداری و ویژگی لاک قوطی بسته‌بندی بر مهاجرت آلومینیوم به درون آبجوی بدون الکل و ویژگیهای حسی آن می‌باشد. م...
[ 5 ] - استخراج و ارزیابی خصوصیات فیزیکو شیمیایی روغن سالیکورنیا گونه Salicornia persica Akhani sub sp. rudshurensis Akhani
سابقه و هدف: سالیکورنیا گونه‌ای از گیاهان هالوفیت (شوری پسند) است. در این مطالعه به بررسی ساختار و ویژگیهای فیزیکوشیمیایی روغن گیاه سالیکورنیا گونه Salicornia persica Akhani sub sp. rudshurensis Akhani پرداخته شده است. مواد و روش‌ها: برای استخراج روغن گیاه سالیکورنیا از روش سوکسله استفاده شد و روغن استخراج شده، با استفاده از دستگاه کروماتوگرافی گازی ارزیابی و پروفایل اسیدهای چرب و همچنین خصوص...
