Abstract

The present study aimed to evaluate the influence of NaCl replacement by KCl (15, 20 and 25%) on the sensory characteristics of dry-cured loins. A rapid descriptive method called Flash Profile (FP) was used for sensory evaluation in order to verify if this technique allow to discriminate between these kinds of meat products in a rapid way. The sensory results obtained by FP were complemented with those obtained applying dynamic sensory techniques as time-intensity (TI) and Temporal Dominance of Sensations (TDS). FP clearly discriminates between dry-cured loins samples with different salt replacement level whereas TI and TDS techniques contributed with additional dynamic sensory information. Moreover, TDS technique which is a multi-attribute temporal method provided an interesting information about the interactions among attributes along consumption. Significant differences in the temporal perception of the flavor and texture attributes evaluated were detected, especially between normal samples and dry-cured loins with higher salt replacement levels (20 and 25%).

摘要

本研究旨在评估用 KCl(15%、20%和 25%)替代 NaCl 对干腌里脊肉感官特性的影响。采用快速描述性方法(Flash Profile,FP)进行感官评价,以验证该技术是否能够快速区分这些类型的肉类产品。通过 FP 获得的感官结果与通过动态感官技术(时间强度法 TI 和感官主导时间 TDS)获得的结果相补充。FP 清楚地区分了不同盐替代水平的干腌里脊肉样品,而 TI 和 TDS 技术则提供了更多的动态感官信息。此外,作为一种多属性时间方法的 TDS 技术提供了关于消费过程中属性之间相互作用的有趣信息。在评估的风味和质地属性的时间感知方面检测到了显著差异,尤其是在正常样品和盐替代水平较高(20%和 25%)的干腌里脊肉之间。
