ملخص المقالة :
دوغ یک فرآورده تخمیری شیر است و بهعنوان یک نوشیدنی ملی ایرانی محسوب میشود. این پژوهش با هدف اندازه گیری میزان دو نگهدارنده شیمیایی بنزوات سدیم و سوربات پتاسیم و همچنین اندازهگیری ویژگیهای شیمیایی شامل میزان pH، ماده خشک بدون چربی (SNF)، چربی و نمک در 61 نمونه دوغ صنعتی از 16 کارخانه متفاوت و زمان های متفاوت تولید، موجود در بازار شیراز انجام شد. میانگین غلظت سوربات پتاسیم و بنزوات سدیم در نمونهها بهترتیب 84/31 و 83/31 میلیگرم در کیلوگرم بود. ازآنجاییکه مطابق استاندارد ملی ایران در دوغ نباید هیچ گونه نگهدارندهای اضافه شود از نظر وجود نگهدارندههای سوربات پتاسیم و بنزوات سدیم بهترتیب 8/73 و 3/85 درصد از نمونه ها غیراستاندارد بودند. از نظر میزان pH و SNF 100 درصد، نمک، 1/95 درصد و چربی، 5/70 درصد نمونه های دوغ طبق استاندارد ملی ایران بودند. در این مطالعه 5/11 درصد نمونهها فقط حاوی سوربات پتاسیم و 23 درصد فقط حاوی بنزوات سدیم بودند و 3/62 درصد حاوی هردو نگهدارنده بودند. بین مدتزمان ماندگاری و مقدار بنزوات سدیم نمونه ها همبستگی معنی دار وجود نداشت. اما بین مدتزمان ماندگاری و مقدار سوربات پتاسیم نمونهها همبستگی معنی دار بود (001/0p=، 37/0r =). نتایج این مطالعه نشان داد که باوجود قوانین موجود در استاندارد ملی ایران از این نگهدارندهها که سلامت مصرف کننده را به خطر میاندازند در تولید این فرآورده مهم تخمیری شیر استفاده میگردد.
