چکیده
پنیر یکی از فرآورده­های شیری با ارزش به شمار می­آید که نقش پررنگی در تغذیه بیشتر افراد جامعه دارد. در خلال فرایند تولید یا پس از آن ممکن است پنیر دچار آلودگی کپکی شود که این رویداد سبب به خطر افتادن سلامتی محصول و کاهش بازارپسندی آن می­شود. پنیر از جمله مواد غذایی است که شرایط مناسب برای رشد قارچ­ها را داراست. هدف از این تحقیق جداسازی و شناسایی کپک­های آلوده کننده پنیرهای فراپالوده عرضه شده در شهرستان فسا بوده است. بدین منظور به طور تصادفی 110 نمونه از قوطی­های پنیر کارخانه­های مختلف از بازار جمع­آوری و به دو صورت در باز و در بسته نگهداری شدند. پس از رشد، شناسایی کپک­ها به دو روش ریخت­شناسی و مولکولی انجام پذیرفت. نتایج نشان دادند که بیشترین میزان آلودگی پنیرهای در باز مربوط به کپک Penicillium بوده و بعد از آن Aspergillus، Paecilomyces و Trichoderma قرار دارند. در پنیرهای در بسته نیز کپک Byssochlamys spectabilis بیشترین آلودگی را به خود اختصاص داد که در طی این تحقیق برای اولین بار در ایران این نوع قارچ جداسازی و شناسایی شد.

چکیده English

Cheese is one of the valuable dairy products that has a significant role in feeding most people in society. During or after the production process, cheeses may become contaminated with moulds, which can endanger the health of the product and reduce its marketability. Cheese is one of the foods that has the suitable conditions for the growth of fungi. The purpose of this study was to isolate and identify the contaminants of ultrafiltration (UF) cheeses offered in Fasa city. For this purpose, 110 samples of cheese cans from different factories were randomly collected from the market and kept both open and closed. After growth, moulds were identified morphologically and molecularly. The results showed that the highest contamination of open cheeses was related to Penicillium, followed by Aspergillus, Paecilomyces and Trichoderma. In closed cheeses, Byssochlamys spectabilis was the most contaminated mould. During this study, for the first time in Iran, this type of fungus was isolated and identified.
