[ 1 ] - تعیین میزان پکتین گل آفتابگردان و بررسی کیفی آن به منظور استفاده در صنایع غذایی
مقدمه: پکتین مولکول کربوهیدرات پیچیده ای است که از واحدهای 1 و4 - آلفا دی گالاکترونیک اسید که برخی از گروه‌های اسیدی آن با متانول استر شده‌اند تشکیل شده است. پکتین‌ها کاربرد وسیعی در صنایع دارویی و غذایی از جمله تولید ژله، مربا و مارمالاد دارند. این تحقیق به منظور تعیین میزان پکتین، درجه استریفیکاسیون و اسید گالاکترونیک پکتین گل آفتابگردان و استفاده آن در صنایع غذایی صورت پذیرفت. مواد و روش‌ها...
[ 2 ] - Evaluation of Antioxidants in Bone Mineral Density of Iranian Osteoporotic Women
Objective(s) Bone is a dynamic tissue that is continuously renewed throughout life by the process of bone remodeling. Antioxidant system might be involved in the pathogenesis of bone loss, so the aim of this study was to evaluate the total antioxidant capacity (TAC), vitamin C and vitamin E levels of plasma besides measuring enzymatic antioxidants, superoxide dismutase (SOD), catalase (CAT) an...
[ 3 ] - Simultaneous Measurement of Zinc, Copper, Lead and Cadmium in Baby Weaning Food and Powder Milk by DPASV
Apart from the breast milk, infant formula and baby weaning food have a special role in infant diet. Infants and young children are very susceptible to amount of trace elements. Copper and zinc are two elements that add in infant food. Lead and cadmium are heavy metals that enter to food chain unavoidably. DPASV is a benefit and applicable method for measurement of trace elements in food produc...
[ 4 ] - Effect of Roasting Process on Total Phenolic Compounds and γ-tocopherol Contents of Iranian Sesame Seeds (Sesamum indicum)
Sesame (Sesamum indicum L.) seed and oil have long been used widely as healthy foods to supply energy and prevent aging. Some of the main active anti-oxidative constituents in sesame seeds are γ-tocopherol and phenols. The purpose of this study was to investigate the relationship between roasting temperature and time with γ-tocopherol and total phenolic compounds (TPC) of sesame seeds when roas...

[ 7 ] - گزارش میزان باقی مانده آفت کش ها در نمونه های ملون به روش گاز کروماتوگرافی طیف سنجی جرمی
Background and purpose: Widespread use of plant pesticides in agriculture resulted in increasing concerns about pesticide hazards. In this research, the residual levels of pesticides in melons were evaluated by gas chromatography-mass spectrometry (GC-MS). Materials and methods: In this study, 75 samples of melons in Tehran market were used for simultaneous analysis of a variety of common pest...
[ 8 ] - The Erythrocyte Catalase Enzyme Activity in Iranian Osteoporotic Women
Osteoporosis is a disease of high prevalence with increased bone loss. It has potential public health threat and that the health authorities had taken several measures for its control. In recent years, considerable attention has been given to physiopathology of osteoporosis. Oxidative stress has been proved to be involved in bone resorption. Oxidative stress occurs when balance between o...
[ 9 ] - The Relation of the Plasma Ascorbic Acid to Bone Mineral Density in Women Referring to Jami Clinic 2006 Tehran, Iran
Osteoporosis is a silent epidemy of today's world, and is also a prevalent problem of health in Iran. The role of nutrients such as ascorbic acid, a key antioxidant vitamin, in this disease has recently attracted researchers' attention. In this study, we studied the relation between plasma ascorbic acid concentration and bone mineral density (BMD) in women referring to Jami clinic, Tehran,...
