With the growing demand for sustainable practises, the food industry is increasingly adopting circular economy approaches. One example is recycling the symbiotic culture of bacteria and yeast (SCOBY) used in kombucha fermentation to create value-added products. However, consumer acceptance of such novel products remains unclear. To address this, the present study examined consumer attitudes towards ice cream made with SCOBY as an ingredient and how this affected their intention to consume it. Drawing on the theory of planned behaviour (TPB) and additional constructs such as emotions and food neophobia, an online survey was conducted with New Zealand consumers (N = 170). Results showed that the TPB constructs significantly predicted the intention to consume SCOBY ice cream. Moreover, by adding emotions to the constructs, the model's explanatory power was enhanced. Attitudes, subjective norms, and emotions were the main predictors of intention, which in turn was found to be the main predictor of behaviour. Participants' beliefs about the safety and taste of SCOBY ice cream were significantly correlated with their intention and behaviour, as were the opinions of nutritionists/dietitians, friends, and family. The model accounted for 21.7% of the variance in behaviour and 57.4% of the variance in intention. These findings can be used to plan marketing strategies related to waste-to-value-added products such as SCOBY ice cream.
随着对可持续发展实践的需求不断增加，食品行业越来越多地采用循环经济方法。一个例子是回收用于康普茶发酵的细菌和酵母共生培养物（SCOBY），以创造增值产品。然而，消费者对这类新产品的接受程度仍不明确。为了解决这个问题，本研究调查了消费者对以SCOBY为原料制作的冰淇淋的态度，以及这如何影响他们食用它的意愿。借鉴计划行为理论（TPB）以及情绪和食物恐新症等其他构念，对新西兰消费者（N = 170）进行了一项在线调查。结果表明，TPB构念显著预测了食用SCOBY冰淇淋的意愿。此外，通过在构念中加入情绪，模型的解释力得到了增强。态度、主观规范和情绪是意愿的主要预测因素，而意愿又被发现是行为的主要预测因素。参与者对SCOBY冰淇淋安全性和口感的信念与他们的意愿和行为显著相关，营养学家/营养师、朋友和家人的意见也是如此。该模型解释了行为方差的21.7%和意愿方差的57.4%。这些发现可用于规划与SCOBY冰淇淋等从废物到增值产品相关的营销策略。
