چکیده

به منظور تعیین مقدار داکسی نیوالنول (DON) در آرد گندم نمونه‌های آرد از 5 کارخانه بین کارخانجات آرد استان تهران بطور تصادفی انتخاب شد و از هر کارخانه برحسب نوع آرد (آرد کامل، آرد سبوس گرفته، آرد ستاره، آرد نول، و آرد ماکارونی) 5 نمونه 1 کیلو‌گرمی گرفته شد. سپس با استفاده از ستون‌های ایمنو‌افینیتی (Immunoaffinity) عمل استخراج صورت گرفت. آنالیز دستگاهی توسط دستگاه HPLC مجهز به دتکتور UV و ستون 18C با استفاده از فاز حامل استو‌نیتریل– آب به نسبت 90/10 (V/V) روی تمامی نمو‌نه‌ها انجام شد. DON در تمامی 40 نمونة آنالیز شدة آرد وجود داشت. بیشترین مقدار DON در آرد کامل با متوسط میزان آلودگی µg/g 05/130 و کمترین مقدار در آرد سبوس گرفته با متوسط میزان آلودگی µg/g 93/39 بدست آمد. آنالیز آماری داده‌ها نشان داد که اختلاف معنی‌داری بین آرد کامل با آرد ستاره و سبوس گرفته وجود دارد (0171/0p = ).

چکیده [English]

In order to determine the amount of Deoxynivalenol (DON) in flours, five flour factories were selected among Tehran provinces' flour factories. One kilogram samples of five kinds of flour (whole, debranned, Setareh, Nool and Semolina flour) were taken from each factory randomly. The samples were transferred to laboratory and divided into 100 and subsequently into 10 gram of sub samples. Then the samples were extracted by Immunoaffinity column and analyzed with HPLC instrument which was equipped with UV detector and C18 column. Mobile phase was Acetonitrile – Water in the ratio of 10-90 (V/ V).
DON was detected in all fourty flour samples. The Maximum amount of DON was in whole flour with an average level of 130.05µg/g. The minimum amount of DON was obtained in debranned flour with average level of 39.93 µg/g. Statistical analysis of data showed that there is a significant difference between whole flour and debranned and Setareh flours (P value = 0.0171).
