摘要:
为比较贵州4个县域豹皮樟老鹰茶的理化品质,对来自贵州4个县域的用传统铁锅杀青、慢火烘干工艺加工的豹皮樟老鹰茶成品进行生化成分和矿质元素测定。结果表明:江口老鹰茶的各生化成分含量都较高,总黄酮含量最高,品质较好;但其重金属铅含量超标,不符合规定。息烽样品的各生化成分含量也都较高,总黄酮含量仅次于江口样品,且茶多酚和水浸出物含量最高,微量元素锌、镁和硒含量也较高,重金属含量符合国家标准,品质较好。江口老鹰茶的氨基酸组分种类最多,湄潭样品的氨基酸组分种类最少;赤水老鹰茶的微量金属元素含量较高,含有咖啡因,且呈鲜爽味的氨基酸含量较高,具有特异性。综上,贵州4个县域的豹皮樟老鹰茶在理化品质上各有特色。
