The acceptance of a new product depends on its sensory quality and consumers' physiological and psychological aspects. The fear of consuming foods processed by new technologies is an example. This study aimed to investigate the overall acceptance and purchase intention of chitosan-coated beef and lamb meat in blind and informed conditions and to estimate the psychometric properties using the Food Technology Neophobia Scale (FTNS). Beef and lamb meat samples were evaluated for overall acceptance (1 = extremely disliked, 9 = extremely liked) and purchase intention (1 = certainly would not buy, 5 = certainly would buy). A questionnaire containing the Food Technology Neophobia Scale (FTNS) was applied, and sociodemographic data were collected, and 297 consumers participated in this study. For beef, chitosan-coated in the informed condition was the most accepted. In contrast, for lamb meat, the overall acceptance values of control and chitosan treatments in the blind condition were higher than the samples in the informed condition. However, cluster analysis indicated three clusters of consumers with different perceptions for both types of meat. The original FTNS showed factorial invariance, and the abbreviated scale (AFTNS) was used. The final AFTNS model showed good adjustment index (λ = 0.41 - 0.73; χ2 / gl = 3.5; CFI = 0.93; TLI = 0.90; RMSEA = 0.09) and had 8 items. For most consumers in this study, an absence of neophobia was observed (71.1%), indicating that the chitosan-coated meat would potentially be commerced.
新产品的接受程度取决于其感官质量和消费者的生理及心理方面。对食用新技术加工食品的恐惧就是一个例子。本研究旨在调查在盲目和知情条件下壳聚糖涂层牛肉和羊肉的总体接受度和购买意愿，并使用食品技术恐惧量表（FTNS）来评估其心理计量特性。对牛肉和羊肉样品进行总体接受度（1=非常不喜欢，9=非常喜欢）和购买意愿（1=肯定不会购买，5=肯定会购买）评估。应用了包含食品技术恐惧量表（FTNS）的问卷，并收集了社会人口统计学数据，共有 297 名消费者参与了这项研究。对于牛肉，知情条件下的壳聚糖涂层是最受欢迎的。相比之下，对于羊肉，盲条件下对照和壳聚糖处理的总体接受值高于知情条件下的样本。然而，聚类分析表明，对于这两种类型的肉，有三个具有不同感知的消费者群体。原始 FTNS 显示出因子不变性，并使用了缩写量表（AFTNS）。最终的 AFTNS 模型显示出良好的调整指数（λ=0.41-0.73；χ2/gl=3.5；CFI=0.93；TLI=0.90；RMSEA=0.09），有 8 个项目。对于本研究中的大多数消费者，观察到缺乏恐惧（71.1%），这表明壳聚糖涂层的肉类可能具有商业潜力。
