Children are strongly frequent consumers of flavored dairy pro ducts chosen and encouraged by their mothers to achieve nutritional requirements. Therefore, this study was implemented to assess flavored dairy products (UHT milk, pasteurized milk, milk powder, yogurt, drinking yogurt, and ice cream) with two diversified flavors for each product for their trace element levels (Al, Pb, Hg, Cd, As, Sb, Zn, Fe, Cu, B, Se, Ni, Co, Cr, and Mn) using inductively coupled plasma-mass spectrometer (ICP-MS/MS). Zn, Cu, Fe, Mn, Co, and Al were detectable in all examined samples, but they were found to be free of mercury and cadmium. Essential elements (Zn, Cu, Fe, Co, Cr, Mn, B) and Al were maximally determined in chocolate milk powder with mean values of 20.73 ± 0.703, 6.832 ± 0.114, 17.9 ± 4.75, 0.299 ± 0.026, 1.279 ± 0.52, 7.958 ± 0.201, 3.51 ± 0.431, and 4.785 ± 1.590 mg/kg, respectively, while Ni, Pb, and As were utmost measured in strawberry yogurt at 1.591 ± 1.746, 0.09 ± 0.036, and 0.037 ± 0.031 mg/kg, respectively. The Pb value concentrations in samples of strawberry milk powder and pasteurized milk exceeded the regulative limit permitted by the European Commission (0.02 mg/kg). Regarding estimated daily intake (EDI) of toxic metals, strawberry drinking yogurt showed Pb (0.0046 mg/kg/day) and Al (0.164 mg/kg/day) twice daily intakes for toddlers surpassed the tolerable daily intake (TDI). Therefore, the consumption of strawberry yogurt for toddlers showed a possibility of non-carcinogenic risk expressed as THQ and carcinogenic risk (CR) in minimum to maximum values of 1.870-3.740 and 8.40 × 10-1.68 × 10 respectively. The contamination of flavored dairy products should be of greater concern as it is deemed a health crisis. Restrictive control measures must be applied starting from hygienic measures related to dairy animals, harvesting, and preparation of unprocessed materials used in the manufacturing of dairy plants, as the steps of processing and raw material quality have the greatest attention and influence on metal concentrations variability.
儿童是调味乳制品的频繁消费者,他们的母亲会选择并鼓励他们食用这些产品以满足营养需求。因此,本研究采用电感耦合等离子体质谱仪(ICP-MS/MS)对调味乳制品(超高温灭菌牛奶、巴氏杀菌牛奶、奶粉、酸奶、饮用型酸奶和冰淇淋)进行评估,每种产品有两种不同口味,检测其微量元素水平(铝、铅、汞、镉、砷、锑、锌、铁、铜、硼、硒、镍、钴、铬和锰)。在所有检测样品中均检测到锌、铜、铁、锰、钴和铝,但未检测到汞和镉。巧克力奶粉中必需元素(锌、铜、铁、钴、铬、锰、硼)和铝的含量最高,平均值分别为20.73±0.703、6.832±0.114、17.9±4.75、0.299±0.026、1.279±0.52、7.958±0.201、3.51±0.431和4.785±1.590mg/kg,而草莓酸奶中镍、铅和砷的含量最高,分别为1.591±1.746、0.09±0.036和0.037±0.031mg/kg。草莓奶粉和巴氏杀菌牛奶样品中的铅值浓度超过了欧盟委员会允许的监管限值(0.02mg/kg)。关于有毒金属的估计每日摄入量(EDI),草莓饮用型酸奶显示,幼儿每天两次摄入的铅(0.0046mg/kg/天)和铝(0.164mg/kg/天)超过了可耐受每日摄入量(TDI)。因此,幼儿食用草莓酸奶显示出存在非致癌风险,以THQ表示,致癌风险(CR)的最小值至最大值分别为1.870 - 3.740和8.40×10 - 1.68×10。调味乳制品的污染应引起更大关注,因为这被视为一场健康危机。必须从与奶牛、收获以及乳制品工厂制造中使用的未加工材料的制备相关的卫生措施开始实施严格的控制措施,因为加工步骤和原材料质量对金属浓度变化的影响最大且最为关键。
