Alcohol consumption is widespread, and high levels of use are associated with increased risk of developing an alcohol use disorder. Thus, understanding the factors that influence alcohol intake is important for disease prevention and management. Additionally, elucidating the factors that associate with alcohol preference and intake in non-clinical populations allows for product development and optimisation opportunities for the alcoholic beverage industry. The literature on how taste (orosensation) influences alcohol behavior is critically appraised in this review. Ethanol, the compound common to all alcoholic beverages, is generally aversive as it primarily elicits bitterness and irritation when ingested. Individuals who experience orosensations (both taste and chemesthetic) more intensely tend to report lower liking and consumption of alcoholic beverages. Additionally, a preference for sweetness is likely associated with a paternal history of alcohol use disorders. However, conflicting findings in the literature are common and may be partially attributable to differences in the methods used to access orosensory responsiveness and taste phenotypes. We conclude that while taste is a key driver in alcohol preference, intake and use disorder, no single taste-related factor can adequately predict alcohol behaviour. Areas for further research and suggestions for improved methodological and analytical approaches are highlighted.
Precision fermented dairy (PFD) is a novel technology used to produce milk proteins that can be used to replicate conventional dairy (CD) products. With PFD products likely to be available soon in the United Kingdom, this study aimed to explore consumer acceptance of these products. Specifically, the effect of sharing information related to the process and environmental impact of PFD on overall liking and emotional response for yoghurts labelled as CD and PFD. Overall, all participants (n = 62) were willing to try the yoghurts labelled as PFD, and no significant difference in liking between yoghurts labelled as CD and PFD was found, indicating acceptance and trust. However, sharing information slightly increased liking for PFD yoghurt and evoked more positive emotions (‘understanding’, ‘adventurous’ and ‘enthusiastic’). In contrast, information decreased liking for CD yoghurt and had minimal impact on the emotional response, but made participants feel slightly ‘guilty’. In particular, sharing information led high food-neophobic and food technology-neophobic individuals to be more ‘understanding’ towards PFD in comparison to the low-neophobic groups. Findings suggest emotional responses can provide deeper insights beyond liking, which will benefit the food industry when reviewing consumer attitudes. The results show promise that consumers will accept PFD products when available, provided the novel technology can mimic the sensory properties of CD. Furthermore, when marketing products, sharing information may increase liking for sustainable products, but future studies would benefit from exploring the effect of different types of information on consumer acceptance.
