Abstract Temporal Dominance of Sensations (TDS) and Temporal-Check-All-That-Apply (TCATA) are the most popular methods used with consumers for the temporal sensory characterization of a set of products. However, TDS and TCATA share the same limitation: they rely on a predefined and necessarily short list of descriptors. Free-Comment (FC) enables the sensory characterization of a set of products freed of any issue induced by the use of a list of descriptors, but for practical reasons collecting FC descriptions concurrently to the product intake is nearly impossible. Attack-Evolution-Finish (AEF) is an alternative to TDS and TCATA that replace concurrent by retrospective data collection. In AEF, subjects are asked to choose in a list one descriptor for each of the so-called periods: Attack, Evolution, and Finish. The paper introduced Free-Comment Attack-Evolution-Finish (FC-AEF) to extend FC to temporal sensory analysis where descriptor selections of AEF are replaced by FC descriptions. FC-AEF has been used at home with 63 consumers having tasted five dark chocolates. The data were analysed product-wise and period-wise and showed that FC-AEF enabled to provide temporal discrimination and characterization of the products. The product-wise analyses identified in each period the descriptors of each product enabling this discrimination. The period-wise analyses identified for each product the descriptors generating a temporal kinetic of its perception.

与消费者一起使用 Free-Comment 来获得产品的时间感官描述

摘要 感觉时间优势 (TDS) 和时间检查所有应用 (TCATA) 是消费者最常用的方法，用于对一组产品进行时间感官表征。但是，TDS 和 TCATA 具有相同的限制：它们依赖于预定义且必要的简短描述符列表。自由评论 (FC) 能够对一组产品进行感官表征，而不会因使用描述符列表而引起任何问题，但出于实际原因，在产品摄入的同时收集 FC 描述几乎是不可能的。Attack-Evolution-Finish (AEF) 是 TDS 和 TCATA 的替代方案，通过回顾性数据收集代替并发。在 AEF 中，要求受试者在列表中为每个所谓的时期选择一个描述符：攻击、进化和完成。该论文介绍了自由评论攻击进化完成 (FC-AEF) 以将 FC 扩展到时间感官分析，其中 AEF 的描述符选择被 FC 描述取代。FC-AEF 已在家中使用，有 63 名消费者品尝了 5 种黑巧克力。数据按产品和周期进行分析，表明 FC-AEF 能够提供产品的时间区分和表征。产品方面的分析在每个时期确定了每个产品的描述符，使这种区分成为可能。周期分析为每个产品确定描述符，生成其感知的时间动力学。FC-AEF 已在家中使用，有 63 名消费者品尝了 5 种黑巧克力。数据按产品和周期进行分析，表明 FC-AEF 能够提供产品的时间区分和表征。产品方面的分析在每个时期确定了每个产品的描述符，使这种区分成为可能。周期分析为每个产品确定了描述符，生成了其感知的时间动力学。FC-AEF 已在家中使用，有 63 名消费者品尝了 5 种黑巧克力。数据按产品和周期进行分析，表明 FC-AEF 能够提供产品的时间区分和表征。产品方面的分析在每个时期确定了每个产品的描述符，使这种区分成为可能。周期分析为每个产品确定描述符，生成其感知的时间动力学。
