补充资料：茶叶含梗量检验
茶叶含梗量检验
stalk contents inspection of tea
茶叶含梗t检验(stalk eontents inspee-tion of tea)茶叶检验之一。对茶叶中茶梗数量的检测措施。茶梗是茶叶加工后残存f成品茶中的茎、梗部分物体。主要是采摘粗放或精制过程中拣剔不净所致。茶梗在各类茶中都有存在.人小、长短、色泽各异，在一定程度上影响茶叶的外形和内质。日本、埃及等国都列为应施检验项目。对于茶梗含最，茶类不同，要求也不同。一般红绿茶对照贸易标准样茶或成交样茶检验其含梗量，出口的压制茶类可含有茶梗，含梗量指标规定米砖6%、圆茶4一6%、滇沱茶0.5%、川沱茶3%，其检验方法因茶类不同而异。 红绿茶含梗量检验将待检茶叶通过分样器缩分、精确称取茶叶100克，均匀分布于白色瓷盘，用镊子逐一拣出茶梗，合并一起称重，计算(l’分率。 压制茶含梗量检验锯取试样一半《必要时用整块)，放入燕笼内，汽蒸1一3小时，使梗叶易于分离时取出，将梗拣出，在烘箱内按茶叶水分检验法烘干称重，计算茶叶含梗的百分率。(严鸿德)
