料引人的有害元素污染风险较高,而由食品添加剂引人的有害元索污染风险较低。关键词:固体饮料;有害元素;原料;电感耦合等离子体质谱法

ABSTRACT: Objective To establish a method for determination of harmful elements in solid beverages by aeeaa determination and judgment of contaminants in solid beverage. Methods After sample preparation, ICP-MS was used to analyze the contents of lead, arsenic, cadmium, chromium, mercury, aluminum, copper, nickel and boron in different kinds of solid beverages, their sources were also investigated. ResultsThe results revealed that the mean concentrations of harmful elements in solid beverages were in the order: Al > B > Cu> Ni > Cr> As > Pb > Cd > Hg. As a result of the addition of tea powder, the average content of aluminum in powdered tea beverage was as high as 49.4 mg/kg. At the same time, the average contents of boron, copper and nickel in powdered protein beverage were 3.86, 2.87 and 1.43 mg/kg, respectively. While the average contents of nine harmful elements in powdered flavored beverages and other powdered beverages with additives as the main raw material were much lower than the average of the total samples. ConclusionThe risk of contamination of harmful elements introduced by raw materials in solid beverages is higher, but the risk of harmful elements from food additives is lower.
