The use of apple pomace flour (APF) as a fibre enrichment strategy was investigated. The aim of this study was to evaluate consumers' response to intrinsic and extrinsic properties of a bakery premix product when using APF. Apple pomace, a by-product from the juice industry, was dried and ground. APF is high in carbohydrates (47.47%) and fibre (38.48%), and it was used to partially substitute wheat flour and sugar in a cake premix. Acceptability, health, and nutrition questions were evaluated with and without information in terms of regular and fibre-enriched cake. The regular cake score was not affected by information, while the enriched cake's score increased with information. Three clusters were identified. Cluster 1 (29%) showed high liking scores for regular cake, cluster 2 (31%) for the fibre-enriched cake, and cluster 3 (40%) showed similar liking for both. Consumers described the samples and ideal cake using a check-all-that-apply (CATA) questionnaire. Penalty analyses explained differences in acceptability among consumers. Healthiness, tastiness, and fibre content were the main reasons to buy the enriched cake for cluster 2; taste for consumers in cluster 1; and healthiness and taste for consumers in cluster 3. APF as a functional ingredient may be a consumers' choice as a sustainable use of apple pomace.
研究了使用苹果渣粉（APF）作为纤维强化策略的情况。本研究的目的是评估消费者在使用APF时对烘焙预混产品内在和外在特性的反应。苹果渣是果汁行业的副产品，经过干燥和研磨。APF富含碳水化合物（47.47%）和纤维（38.48%），并用于部分替代蛋糕预混料中的小麦粉和糖。在有无关于普通蛋糕和富含纤维蛋糕信息的情况下，对可接受性、健康和营养问题进行了评估。普通蛋糕的评分不受信息影响，而富含纤维蛋糕的评分随信息增加。确定了三个类别。类别1（29%）对普通蛋糕表现出较高的喜爱评分，类别2（31%）对富含纤维蛋糕表现出较高的喜爱评分，类别3（40%）对两者表现出相似的喜爱程度。消费者使用多选（CATA）问卷描述样品和理想蛋糕。惩罚分析解释了消费者之间可接受性的差异。健康、美味和纤维含量是类别2购买富含纤维蛋糕的主要原因；类别1消费者的主要原因是口味；类别3消费者的主要原因是健康和口味。作为一种功能性成分，APF作为苹果渣的可持续利用方式可能是消费者的一种选择。
