چکیده استفاده از پتانسیل مواد طبیعی به‌عنوان افزودنی‌های غذایی به خصوص با توجه به خواص ضد میکروبی آن‌ها جهت کاهش استفاده از نگهدارنده‌های شیمیایی در تولید مواد غذایی، بسیار حائز اهمیت است. در این پژوهش خواص ضد باکتریایی اسانس برگ شمعدانی عطری در شرایط آزمایشگاهی بر روی باکتری های استافیلوکوکوس اورئوس، اشریشیا کلی، سالمونلا انتریتیکا و <e...
[ 2 ] - Exposure Assessment for Some Pesticides through Rice Consumption in Iran Using a Multiresidue Analysis by GC-MS
In communities which consume rice as main food, importance of risk assessment forcontaminants is always taken into consideration by health authorities. The present study isan attempt for monitoring of 56 pesticides from different chemical groups in rice samplescollected from local markets in Tehran and estimation of daily intake of interested pesticidesthrough this monitoring. A valid method ba...
[ 3 ] - A Multi Residue GC-MS Method for Determination of 12 Pesticides in Cucumber
Cucumber is one of the main vegetables in Iranian food basket. A wide range of pesticides are used for crops protection during the cultivation of vegetables such as cucumber due to heavy pest infestation. Analysis of pesticide residues in food and other environmental commodities have become essential requirement for consumers, producers, and food quality control authorities. This study was aime...
[ 4 ] - Development and Validation of a Micellar Capillary Electrophoresis Method for Determination of IFNβ-1b in Lyophilized Formulation of a Biosimilar Product
Human interferons (IFNs) are key cytokines secreted by immune system. They have several effects such as antiviral and anti tumors activity, activating immune cells and healing of multiple sclerosis. The type IFNs present in humans are α, β and Υ. IFN β is a polypeptide, normally produced by fibroblasts and seems to be more species-specific than IFN . Structural properties of I FNs are importan...
[ 5 ] - 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...
[ 6 ] - Effect of Cooking Process on the Residues of Three Carbamate Pesticides in Rice
A gas chromatography mass spectrometry with spike calibration curve method was used to quantify three carbamate pesticides residue in cooked white rice and to estimate the reduction percentage of the cooking process duration. The selected pesticides are three carbamate pesticides including carbaryl and pirimicarb that their MRL is issued by “The Institute of Standards of Iran” and propoxur whic...

[ 12 ] - بررسی میزان جیوه در میگوهای عرضه شده در بازار تهران
زمینـه مطالعه: میگو منبع غنی از پروتئین‌ها، پپتیدها، اسیدهای آمینه، مس، منیزیم، ید و روی بوده و مصرف این محصول روبه گسترش می‌باشد. متأسفانه در چند سال اخیر جیوه از راه‌های مختلف و به مقادیر بسیار زیادی وارد اکوسیستم‌های آبی و دریایی شده که به دلیل تجمع بیولوژیک، ماندگاری بالا و خطرات مسمومیت آن؛ قابل تامل و بررسی خواهد بود. هدف: تعیین سطح آلودگی به جیوه در میگوهای عرضه شده در سطح شهر تهران و مق...
[ 13 ] - کارایی تصفیه خانه متداول فاضلاب در حذف آنتی بیوتیک و تعیین غلظت آن، تصفیه خانه فاضلاب اکباتان و جنوب تهران: مطالعه موردی
Background and Objective: Antibiotics are a group of emerging contaminants in the aquatic environment. Antibiotic residues threaten the human health and ecosystem in the low concentrations found in the environment. Hence, the present work has been conducted to investigate the occurrence and removal efficiency of most prescribed antibiotics including amoxicillin, penicillin, cefixime, cephalexin...
[ 14 ] - Study of the concentration of Arsenic, Cadmium and lead heavy metals in different types of domestic and imported Rice of Iran
Background & Aims of the Study: Soil and water pollution with heavy metals is considered one of the most important environmental tensions for plants. These metals can endanger human life through food chain. Rice is one of the high consumption type of grains in the world that is widely seen in the diet of people. Thus present research seeks to study the rate of Arsenic, Cadmium and Lead in diffe...
