摘　　要：安徽霍山黄芽常用霍山金鸡种和舒茶早两个品种制得,有黄茶制法和绿茶制法两种产品。采用偏好属性启发(Preferred attribute elicitation,PAE)法和时间强度(Time-intensity,TI)法探究不同品种、不同制法霍山黄芽的消费者偏好及滋味属性强度变化。PAE试验中评价员就生成的属性达成一致后,根据其影响喜好的重要性对感官属性进行排序和强度赋值,结果表明,滋味秩和(115)>香气秩和(81)>外形秩和(44),被消费者共同认为重要的属性词有回甘、花香和毫。TI试验中评价员根据几何平均值M筛选出回甘、醇、苦、鲜、涩5个描述词;霍山金鸡种黄茶制法样品的回甘、鲜味属性高于绿茶制法样品,醇、苦、涩属性低于绿茶制法样品;舒茶早表现出相反趋势。本研究利用PAE法和TI法提取出消费者视角的霍山黄芽重要属性,并通过观察不同品种、不同制法霍山黄芽的动态属性变化,基于消费者视角提出了霍山金鸡种更适合采用黄茶制法、舒茶早更适合采用绿茶制法,从而科学指导黄茶企业因地制宜地组织生产和销售。Huoshan huangya of Anhui is commonly made from tea cultivars‘Huoshan-jinjizhong’and‘Shuchazao’,with the processing methods of yellow tea and green tea.This study dealt with consumer preferences and variation of taste intensity for different cultivars and processing of Huoshan huangya using the Preferential attribute elicitation(PAE)method and Time-intensity(TI)method.In the PAE test,after the evaluators reached an agreement on the generated attributes,they ranked and assigned the intensity of sensory attributes according to the importance of their influence on preferences.The results show that the taste rank sum(115)>aroma rank sum(81)>appearance rank sum(44),and all consumers commonly selected the important descriptors:sweet aftertaste,flowery aroma and tippy.In the TI test,five descriptors were selected based on the geometric mean M value:sweet aftertaste,mellow,bitter,fresh,and astringent.Descriptors of sweet and fresh of yellow tea made from the tea cultivar‘Huoshan-jinjizhong’were higher than that of green tea,and descriptors of mellow,bitter,astringent were lower than those of green tea.Teas made from‘Shuchazao’showed the opposite trend.This study applied PAE and TI methods to clarify the important characteristics of Huoshan huangya,by observing the dynamic sensory changes of Huoshan huangya with different cultivars and different processing methods,to propose yellow tea made from‘Huoshan-jinjizhong’and green tea made from‘Shuchazao’were more suitable from the perspective of consumers.This paper scientifically guided yellow tea enterprises to organize production and sales according to local conditions.
