摘要: 制定具有标准级差代表性的实物标准样对黄茶的生产流通具有重要意义。分别招募80名普通消费者和22名初级评价员,对皖西黄茶的3大类(黄芽茶、黄小茶、黄大茶)9个等级实物标准样进行排序检验及Napping-UFP法分析。结果表明,在排序检验法中仅依据外形可基本实现对8个标准样的判定(其中黄芽特级与一级不能判别);在Napping-UFP法中,22名初级评价员仅根据外形也能较好地区分不同等级的黄茶样品,根据香气或滋味可以准确区分黄芽茶、黄小茶和黄大茶,并能准确区分黄大茶的轻火样和足火样;同时初级评价员给出了较为丰富的描述词(外形33个,香气21个,滋味24个),外形描述词中的“绿”“黄”“多梗”,香气描述词中的“嫩香”“甜香”“烟丝”,滋味描述词中的“鲜”词频较高,可以用于皖西黄茶实物标准样的级差判别,有利于消费者的理解与接受,以及皖西黄茶的市场推广。

Abstract: It is of great significance for the production and popularization of yellow tea with standard grade difference. In this paper, 9 yellow tea samples of 3 categories (yellow bud tea, small-leaf yellow tea, large-leaf yellow tea) from western Anhui province were selected. Then 80 consumers and 22 assessors were recruited to analyze these samples using ranking and Napping-UFP respectively. The results show that the 8 standard samples can be distinguished according to the appearance by ranking, except the super class and the first class of bud tea. In Napping-UFP, 22 assessors could distinguish different grades of samples by appearance. The categories (yellow bud tea, small-leaf yellow tea and large-leaf yellow tea) and the roasting degrees (light fire and sufficient fire) could be accurately distinguished based on their aroma or taste. At the same time, the assessors provided relatively rich descriptive terms (33 of appearance, 21 of aroma and 24 of taste), including "green", "yellow" and "fairly stalk" in the appearance attributes, "tend aroma", "sweet aroma" and "tobacco" in the aroma attributes, and "fresh" in the taste attributes. These terms could be used to accurately assess yellow tea from western Anhui province, which is conducive to consumers’ understanding and acceptance, as well as the market promotion of yellow tea from western Anhui province.

Key words: yellow tea from western Anhui province, standard samples of yellow tea, ranking, Napping-UFP
