The examination of various elements in the milk products is very important in the food sector in respect of food quality and safety. The aim of this study was to determine the concentrations of calcium (Ca), cobalt (Co), cadmium (Cd), copper (Cu), chromium (Cr), iron (Fe), mercury (Hg), potassium (K), magnesium (Mg), sodium (Na), nickel (Ni), phosphorus (P), lead (Pb) and zinc (Zn) in white cottage cheese or cottage cheese supplemented with various additives (white, lacto-free, chive, tzatziki, mustard + onion, chili, active protein) available on the market of Slovakia. All essential elements were within the reference range. Cottage cheese enriched with tzatziki showed higher amount of Cu, Fe, K, and Zn. Mustard + onion cheese contained high values of Ca, Co, Mg, and Ni. In white cottage cheese high amount of Cr, Mn, and P was measured. The content of xenobiotic metals was below permitted limit. The contribution to PTWI (Provisional tolerable weekly intake) suggested very low dietary exposure to heavy metals as Cd, Hg, and Pb as well as other metals (Cu, Ni, and Zn) in cottage cheese. Numerous correlations between concentrations were observed. MOE (Margin of Exposure) evaluation denoted that average consumption of cottage cheese does not pose any high cardiovascular and nephrotoxicity threat.

就食品质量和安全而言，对乳制品中各种元素的检查在食品领域非常重要。这项研究的目的是确定钙（Ca），钴（Co），镉（Cd），铜（Cu），铬（Cr），铁（Fe），汞（Hg），钾（K）的浓度，白干酪或干酪中添加的镁，镁，钠，镍，磷，铅，锌和锌，并添加了各种添加剂（白色，无乳糖，细香葱， tzatziki，芥末+洋葱，辣椒，活性蛋白）可在斯洛伐克市场上购买。所有必要元素均在参考范围内。富含tzatziki的干酪显示出较高的Cu，Fe，K和Zn含量。芥末+洋葱奶酪中的Ca，Co，Mg和Ni含量很高。在白色干酪中，测出了大量的Cr，Mn和P。外源性金属的含量低于允许的限值。对PTWI（临时可耐受的每周摄入量）的贡献表明，膳食中奶酪中的重金属Cd，Hg和Pb以及其他金属（Cu，Ni和Zn）的暴露量非常低。观察到浓度之间的许多相关性。教育部（MOE）评估表明，奶酪的平均消费量不会对心血管和肾毒性构成任何高威胁。
