[ 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...
[ 5 ] - Comparative Antioxidant Activity and Total Flavonoid Content of Persian Pomegranate (Punica granatum L.) Cultivars
Pomegranate (Punica granatum L.), Lythraceae, is mainly grown in Mediterranean region. It is one of the major cultivated productions of Iran, which have been used in folk medicine for many centuries. It has been proved that pomegranate has a high antioxidant activity and is effective in the prevention of atherosclerosis. This study compares the antioxidant activity, total phenolic and flavonoid...
[ 6 ] - Detection of Oxytetracycline Residue in Infant Formula by High-Performance Liquid Chromatography (HPLC)
Determination of drug residues in food is of great importance due to their toxicity. Long-term exposure with low level of drug residues could be important, especially in children. Based on document study, oxytetracycline (OTC) is a prophylaxis and treatment agent for great number of diseases and possesses a broad spectrum activity against many pathogenic organisms and can be toxic or cause alle...
[ 7 ] - Human Breast Milk Provides Better Antioxidant Capacity than Infant Formula
Human milk contains all of the constituents that are required for the optimal growth and development of a neonate. It supports the development of brain, immune, and physiological systems. This study aimed to consider the significance of breast milk in preventing oxidative stress by comparing total antioxidant capacity (TAC) in breast and formula milk for premature infants, demonstrating the rel...

[ 13 ] - Effects of Shirazi Gum Edible Coating Containing of Peppermint Essential Oil on Shelf-life of Fresh Greenhouse Cucumbers (Cucumissativus) and Its Quality Assessment during Storage in Refrigerator
Background and Objectives: Greenhouse cucumber is one of the most important summer crops of Iran. Quality of the product is immediately lost after harvest due to physicochemical changes. Thus, use of special pre-processes (especially use of edible coating) to delay their maturity and increase the shelf-life of the product is important. Materials and Methods: To decrease weight loss, preserve nu...
