BACKGROUND AND AIM
Monitoring food quality and safety remain a pressing issue. The intermediate results of the study on the residual amounts of heavy and toxic elements in food products are presented herein. The aim of this study was the determination of heavy metals in milk and fermented milk products from basic farms in the Almaty region, Kazakhstan.
MATERIALS AND METHODS
A total of 120 raw milk samples and 80 cottage cheese samples were analyzed. The milk and cottage cheese samples were subjected to mineralization during the analysis to remove organic impurities and determine the heavy metal concentrations using atomic absorption spectrometry.
RESULTS
The contents of cadmium, lead, and arsenic in all raw materials and food products did not exceed the maximum permissible concentrations.
CONCLUSION
The dairy samples showed low contents of cadmium, mercury, lead, and arsenic that did not exceed the allowable concentrations for basic farms in the Almaty region.
背景与目的
监测食品质量与安全仍是一个紧迫问题。本文展示了食品中重金属和有毒元素残留量研究的中期结果。本研究的目的是测定哈萨克斯坦阿拉木图地区基础农场牛奶及发酵奶制品中的重金属含量。
材料与方法
共分析了120份生牛奶样本和80份凝乳样本。在分析过程中，对牛奶和凝乳样本进行了矿化处理，以去除有机杂质，并使用原子吸收光谱法测定重金属浓度。
结果
所有原材料和食品中镉、铅和砷的含量均未超过最大允许浓度。
结论
乳制品样本中镉、汞、铅和砷的含量较低，未超过阿拉木图地区基础农场的允许浓度。
