摘要: 以广西浦北县不同厂家的小青柑陈皮普洱茶为研究对象,根据相关标准要求对其理化指标、重金属、农药残留和微生物进行了分析和评价。结果表明,小青柑陈皮普洱茶水分含量为7.25~11.50 g/100 g,总灰分含量为5.2%~7.9%,水浸出物含量为26.4%~33.4%,茶多酚含量为5.1%~13.1%;铅含量为0~0.079 mg/kg,砷含量为0~0.062 mg/kg,镉含量为0.015~0.034 mg/kg,铬含量为0.73~1.02 mg/kg,铜含量为8.65~15.7 mg/kg;所检测的16种农药残留项目中的5种(六六六、联苯菊酯、硫丹、丙溴磷和毒死蜱)部分样本中有少量检出,微生物菌落总数、大肠菌群和霉菌也有不同数量的检出,所有检出结果均低于相应的标准限值;其余农药残留项目和所有样本中的致病菌(沙门氏菌、志贺氏菌、金黄色葡萄球菌)均未检出,表明广西浦北县小青柑陈皮普洱茶理化指标、重金属、农药残留和微生物符合标准要求,产品质量安全可靠。
