The development of new food products can be expedited by understanding the physicochemical attributes that are most relevant to consumers. Although many objective analyses are possible, not all are a suitable proxy to serve as quality markers associated with sensory preferences. In this work, we selected nine candidate laboratory assays to use on six commercial salamis, which were also eaten and informally described by a consumer discussion group familiar with China-sourced meat products. Several objective measures were strongly related to the flavour perceptions: (i) texture: instrumental texture values, fat release at oral temperature and fat saturation ratios, (ii) aroma: volatile compounds (e.g., alcohols and esters) associated with microbial fermentation and spices (terpenes and sulphur compounds) and (iii) taste: kokumi taste receptor responses. The fat released at oral temperature was associated with unsaturated fatty acids (r = 0.73). However, there was less explanatory worth for associations between sensory perceptions and proximate composition, water activity, pH or L*, a*, b* colourimetry.
通过了解与消费者最为相关的物理化学特性,可以加快新型食品的开发进程。尽管可以进行许多客观分析,但并非所有分析都适合作为与感官偏好相关的质量指标。在这项研究中,我们选择了九种候选实验室检测方法,用于对六种市售意大利腊肠进行检测,一个熟悉中国产肉类产品的消费者讨论小组也品尝了这些腊肠并进行了非正式描述。有几种客观测量方法与风味感知密切相关:(i)质地:仪器质地值、口腔温度下的脂肪释放量和脂肪饱和度;(ii)香气:与微生物发酵相关的挥发性化合物(如醇类和酯类)以及香料(萜类和硫化合物);(iii)味道:鲜味味觉受体反应。口腔温度下释放的脂肪与不饱和脂肪酸相关(r = 0.73)。然而,感官感知与近似成分、水分活度、pH值或L*、a*、b*比色法之间的关联解释价值较低。
