摘　　要：为比较定量描述分析(quantitative descriptive analysis,QDA)法和check-all-that-apply(CATA)法用于褐色酸奶时的优缺点,6名经过培训的感官评价员建立褐色酸奶的感官描述词,对每个感官描述词的定义和参比样的强度达成共识后进行定量描述分析,招募18名消费者产生褐色酸奶的感官描述词,再招募67名消费者根据这些描述词进行CATA法分析。结果表明,QDA法产生了22个褐色酸奶感官描述词。棕色、焦糖香和焦糖味未出现在其他种类酸奶的描述词中,其中焦糖香贡献最大;CATA法中消费者使用了24个词语,其中棕色的选择频率高于焦糖味。2种方法均能有效地区分样品间的感官差异,且结果具有相似性。QDA法准确性更高,但CATA法具有成本低和时间短的优点,且能同时进行消费者接受度检验,在产品开发和市场调研方面具有广阔的应用前景。This study aimed to discuss the advantages and disadvantages of using quantitative descriptive analysis(QDA)and check-all-that-apply(CATA)in brown yogurt description.The sensory descriptors of brown yogurt were established by six trained assessors.After a consensus about sensory descriptor definition and scale was reached,the QDA was performed.A total number of 18 consumers were recruited to generate the sensory descriptors for brown yogurt.Additional 67 consumers were assigned to carry out CATA according to these sensory descriptors.Results indicated that 22 sensory descriptors for brown yogurt were obtained using QDA.Brown color,camerlsed and caramel flavor did not occur in the sensory descriptors of other kinds of yogurt,and camerlsed displayed the most contribution.For CATA,up to 24 sensory descriptors were used by consumers,and brown color was more frequently used than caramel flavor.Both methods effectively distinguished the sensory differences between different samples.The results obtained by these two methods were similar;However,QDA exhibited higher accuracy than CATA.CATA possessed the advantage of low-cost and time savings,while accomplishing consumer acceptance test simultaneously.CATA has a promising application in terms of product development and market survey.
