چکیده مقاله :

پنیر فراورده ای است متشکل از چربی و پروتئین شیر، به همراه کلسیم و فسفری که به صور مختلف با پروتئین شیر ترکیب شده اند. با توجه به اهمیت مصرف پنیر در بین مردم ایران و با توجه به این که این محصول یکی از مهمترین فراورده های لبنی است و براساس آمارهای موجود حدود 20 درصد شیر تولیدی کشور در بخش صنایع لبنی تبدیل به پنیر می شود که از این مقدار سهم تولید پنیر سنتی در حدود 80 درصد می باشد، هدف از این تحقیق، ارزیابی میزان آلودگی پنیرهای سنتی عرضه شده در مناطق مختلف شهرستان کرج بود. مطالعه حاضر از نوع توصیفی- مقطعی، در تابستان 1398 با نمونه برداری از بخش های مختلف شمال، غرب، شرق، جنوب و مرکز شهرستان کرج انجام شد. چهار نوع پنیر فله لیقوان تبریز، لاکتیکی، سفید و گچی در پنج منطقه جغرافیایی با چهارتکرار، از نظر وجود باکتری استافیلوکوکوس اورئوس مورد بررسی قرار گرفت. مطالعه حاضر نشان از آلودگی پنیرهای سنتی عرضه شده در شهرستان کرج و مناطق مختلف آن دارد، اگرچه که میزان آلودگی در غرب شهرستان، از سایر مناطق بیشتر بوده است. در بین مناطق، منطقه شرق با کمترین میزان آلودگی در بین سایر مناطق و وجود آلودگی تنها در پنیر گچی، به عنوان کم خطر ترین منطقه شناسایی شد. در مقابل وجود آلودگی بالا در هر چهار نوع پنیر مورد مطالعه در غرب شهرستان کرج، این بخش از شهرستان کرج را بر اساس نتایج این تحقیق به عنوان پرخطرترین منطقه در مصرف پنیرهای سنتی معرفی کرد.

چکیده انگلیسی:

Cheese is a product consisting of fat and milk protein, along with calcium and phosphorus that are combined with milk protein in various ways. Due to the importance of cheese consumption among the people of Iran and considering that this product is one of the most important dairy products and according to available statistics, about 20% of the milk produced in the dairy industry is converted into cheese, of which the share of production Traditional cheese is about 80%. The purpose of this study was to evaluate the level of contamination of traditional cheeses offered in different areas of Karaj. The present descriptive cross-sectional study was conducted in the summer of 1398 by sampling different parts of the north, west, east, south and center of Karaj . Four types of bulk cheeses of Tabriz Ligvan, lactic, white and gypsum in five geographical areas with three replications were examined for the presence of Staphylococcus aureus. The results shows the contamination of traditional cheeses and its different areas, although the rate of contamination in the west was higher than other areas. Among the regions, the eastern region with the lowest level of pollution among other regions and the presence of contamination only in gypsum cheese, was identified as the least dangerous region. In contrast to the existence of high pollution in all four types of cheese studied in the west. based on the results, this part of Karaj was introduced as the most dangerous area in the consumption of traditional cheeses.
