چکیده

با توجه به خصوصیات شیر، ارزیابی ویژگی‌های آن برای تولیدکنندگان شیر و صنایع تولیدی فرآورده‌های لبنی ضروری است. در این مطالعه 240 نمونه شیر خام جمع‌آوری شده از دامداری‌های استان خوزستان طی فصول مختلف سال‌های 1400-1399 از نظر شمارش کلی باکتریایی، تعداد یاخته‌های پیکری و اسیدیته مورد بررسی قرار گرفتند. نتایج نشان داد که ضمن تفاوت معنی‌دار داده‌ها بین ویژگی‌های شیر دو نوع دامداری (صنعتی و سنتی) و همچنین فصول مختلف (بهار و تابستان در مقایسه با دو فصل دیگر)، به‌طور کلی رابطه معکوسی میان اسیدیته با شمارش کلی باکتریایی و همچنین تعداد یاخته‌های پیکری وجود دارد (05/0>p). بنابراین فاکتورهای ذکر شده برای تشخیص سلامتی شیر خام مهم است. در نتیجه می‌توان اظهار نظر نمود که ایجاد گاوداری‌های صنعتی، رعایت بهداشت حین شیردوشی و طی زنجیره انتقال شیر از مزرعه تا کارخانه و همچنین اعمال سیستم‌های بهداشتی نظیر تجزیه و تحلیل خطر و کنترل نقاط بحرانی، عملیات بهداشت خوب و عملیات تولید خوب، در سلامتی شیر خام تولیدی الزامی می‌باشد.

چکیده [English]

Due to the properties of milk, control of this product and evaluation of its characteristics is necessary for milk producers and dairy products industries. In this study, 240 raw milk samples collected from livestock farms in Khuzestan province during different seasons of 1399-1400 were analyzed in terms of the total count of microorganisms, the number of corporal cells and acidity. The results showed that there is a significant difference in the data between the two types of animal husbandry (industrial and traditional) and also different seasons (spring and summer compared to the other two seasons). Also, results showed an inverse correlation between acidity with total bacterial count and somatic cell count (p<0.05). So, the aforementioned factors are important for diagnosing the safety of raw milk. For this purpose, it seems establishing of industrial dairy farms, hygienic management through the milking and during the milk-to-factory transmission chain and also applying hygienic systems such as hazard analysis and critical control points, good manufacturing practice and good hygienic practice are required.
