In adolescents and adults, a link has been observed between food neophobia (the rejection of unfamiliar foods) and olfaction, which plays a key role in food acceptance. However, research on olfaction's role in food acceptance and rejection among children is limited. Utilizing the U-sniff test and the Italian Child Neophobia Scale, this study investigated associations between odor awareness, odor identification, food neophobia, and the acceptance of fruits and vegetables in Swedish children aged 9–12 years (<em>n</em> = 126). A Swedish version of the ChiPSO questionnaire on odor awareness (including subscales for food, social and environmental odors) was developed, and initial validation conducted through back translation, cognitive interviews, and exploratory factor analysis. Fruit and vegetable acceptance was assessed through a questionnaire and a tasting session. Findings indicated that food neophobia was associated with lower fruit and vegetable acceptance (questionnaire ρ = −0.296, <em>p</em> = 0.002; tasting session ρ = −0.273, <em>p</em> = 0.004) but no significant associations observed with odor awareness (ρ = 0.159, <em>p</em> = 0.094) or odor identification performance (ρ = −0.141, <em>p</em> = 0.176). However, odor awareness was negatively associated with vegetable acceptance (ρ = −0.200, <em>p</em> = 0.034), while odor identification performance showed no significant associations (questionnaire ρ = −0.049, <em>p</em> = 0.638; tasting session ρ = −0.101, <em>p</em> = 0.316). A negative association was found between odor identification performance and environmental odor awareness (ρ = −0.269, <em>p</em> = 0.010). This suggests that some children may struggle to identify odors due to emotional reactions and avoidant behaviors, reducing engagement and hindering identification. Further exploration of the relationship between olfaction and children's food acceptance or rejection is encouraged.</div></div>","PeriodicalId":322,"journal":{"name":"Food Quality and Preference","volume":"126 ","pages":"Article 105384"},"PeriodicalIF":4.9,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143103422","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The intensity and pleasantness of the lemon odour remained stable over time, suggesting no olfactory habituation occurred with this food-related odour. Despite this stable visual attention and odour intensity and pleasantness, participants began to diversify their product choices, selecting fewer odour-congruent items over time.</div><div>These findings suggest that while odours continue to direct attention towards matching products, repeated exposure may reduce their influence on product choice, highlighting the complex role of olfactory stimuli in decision-making. The study provides insights into how odours interact with visual cues and influence consumer behaviour in prolonged exposure scenarios.</div></div>","PeriodicalId":322,"journal":{"name":"Food Quality and Preference","volume":"124 ","pages":"Article 105373"},"PeriodicalIF":4.9,"publicationDate":"2024-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142701210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
