Despite the known health benefits and the potential for substituting less environmentally sustainable consumed foods such as meat, the current intake of pulses in developed countries remains less than recommended. Barriers are related to sensory characteristics and lack of knowledge about preparation, while drivers of environmental benefits are intangible. The aim of this study was to investigate the effect of additional information about health or environmental benefits of pulses on the acceptance of novel pulse-based products from chickpeas, black beans, and faba beans. Perceptions of these pulse-based spreads in a blind and informed stage were assessed with 202 consumers in urban and suburban areas of Denmark. In general, the familiar chickpea spread followed by the relatively most unfamiliar black bean spread was liked the most. Only for these two products, additional information increased hedonic perception, regardless of the context (health or environmental benefits). If consumers did not like the spread, as found for the faba bean spread, providing additional information did not significantly alter this perception. Participants' preferences and willingness to pay (WTP) in a discrete choice experiment corresponded to hedonic scores, whereas providing additional information increased the WTP. These findings suggest that extrinsic cues such as health or environmental benefits may only be useful in products with an acceptable baseline taste profile. Moreover, black beans might be investigated as a promising source for further product development due to their acceptance by consumers besides being the comparably most unfamiliar pulse type.
尽管已知食用豆类具有健康益处，并且有可能替代肉类等不太可持续的消费食品，但在发达国家，豆类的当前摄入量仍低于建议量。障碍与感官特征和缺乏有关准备知识有关，而环境效益的驱动因素是无形的。本研究旨在调查关于豆类的健康或环境效益的额外信息对接受新型基于豆类的产品（鹰嘴豆、黑豆和蚕豆）的影响。通过在丹麦市区和郊区的 202 名消费者对这些基于豆类的涂抹食品进行了盲测和知情评估。总的来说，熟悉的鹰嘴豆涂抹食品之后是相对最不熟悉的黑豆涂抹食品，最受欢迎。仅对于这两种产品，无论背景（健康或环境效益）如何，额外的信息都会增加愉悦感。如果消费者不喜欢涂抹食品，就像发现的蚕豆涂抹食品一样，提供额外的信息并不能显著改变这种看法。在离散选择实验中，参与者的偏好和支付意愿（WTP）与愉悦感评分相对应，而提供额外的信息则会增加 WTP。这些发现表明，外在线索（如健康或环境效益）可能仅在具有可接受的基线口感的产品中有用。此外，由于消费者对黑豆的接受程度，除了是最不熟悉的豆类类型外，黑豆可能被视为进一步产品开发的有前途的来源。
