Along with animal production factors, it is important to understand whether demographic factors influence untrained consumer perceptions of eating quality. This study examined the impact of demographic factors and sheepmeat consumption preferences on eating quality scores of American, Australian and Chinese untrained consumers. M. (LL) and m. (SM) were grilled according to sheep Meat Standards Australia protocols and evaluated by 2160 consumers for tenderness, juiciness, flavour and overall liking. Linear mixed effects models were used to analyse the impact of demographic factors and sheepmeat consumption habits on eating quality scores. Consumer age, gender, number of adults in a household and income had the strongest effect on sensory scores ( ≤ 0.05), although, the impact was often different across countries. Frequency of lamb consumption had an impact on sensory scores of American, Australian and Chinese consumers but larger sample sizes in some underrepresented subclasses for Australian and Chinese consumers are needed. Results suggest it is important to balance sensory panels for demographic factors of age, gender, number of adults and income to ensure sensory preferences are accurately represented for these particular populations.
除了动物生产因素外,了解人口统计学因素是否会影响未经培训的消费者对食用品质的认知也很重要。本研究考察了人口统计学因素和羊肉消费偏好对美国、澳大利亚和中国未经培训的消费者食用品质评分的影响。按照澳大利亚羊肉标准规程烤制了腰大肌(LL)和半膜肌(SM),并由2160名消费者对嫩度、多汁性、风味和总体喜好程度进行评价。采用线性混合效应模型分析人口统计学因素和羊肉消费习惯对食用品质评分的影响。消费者年龄、性别、家庭中成年人数量和收入对感官评分的影响最为显著(P≤0.05),不过,不同国家的影响往往有所不同。食用羊肉的频率对美国、澳大利亚和中国消费者的感官评分有影响,但对于澳大利亚和中国消费者中一些代表性不足的亚组,需要更大的样本量。结果表明,平衡感官评价小组中年龄、性别、成年人数量和收入等人口统计学因素很重要,以确保准确反映这些特定人群的感官偏好。
