中文摘要：本研究分析了58个奶样中的黄曲霉毒素M1(AFM(1))污染情况。这些奶样于2013年4-5月随机从意大利博洛尼亚市的超市、零售店、杂货店及专卖店购得。其中有有机奶22个、普通奶36个；每个类别都包括鲜奶、超高温灭菌奶、全脂奶和部分脱脂牛奶。利用基于免疫亲和柱的提取和净化技术测定了样品中AFM(1)含量，并利用HPLC-FD法对该结果进行了分析。结果发现，共有35个样品中检出了AFM(1)，其中，11个有机奶和24个普通奶；两种产品中AFM(1)浓度差异不显著(P > 0.05)；AFM(1)浓度水平在0.009和0.026 ng mL(-1)之间，没有超过限制标准(0.05 mu g kg(-1))。
外文摘要： In the present study, 58 samples of milk were analyzed for the presence of aflatoxin M-1 (AFM(1)). The samples were purchased during the period April-May 2013 in a random manner from local stores (supermarkets, small retail shops, small groceries, and specialized suppliers) located in the surrounding of Bologna (Italy). The commercial samples of milk were either organic (n = 22) or conventional (n = 36); fresh milk samples and UHT milk samples, whole milk samples, and partially skim milk samples were present in both the two considered categories. For the quantification of AFM(1) in milk, the extraction-purification technique based on the use of immunoaffinity columns was adopted and analyses were performed using HPLC-FD. AFM(1) was detected in 35 samples, 11 from organic production and 24 from conventional production. No statistically (P > 0.05) significant differences were observed in the concentration of AFM(1) in the two categories of product. The levels of contamination found in the positive samples ranged between 0.009 and 0.026 ng mL(-1). No sample exceeded the limit defined at community level for AFM(1) in milk (0.05 mu g kg(-1)). This demonstrates the effectiveness of the checks before the placing on the market of these food products. Thus, the "aflatoxins" problem that characterized the summer of 2012 does not seem to have had effect on the contamination level of the considered milk samples.
