Introduction In the present study, we explore the existence of cross-cultural differences in odour-colour correspondences between two European countries with geographic proximity and shared history: England and France. Moreover, we test whether a single chromatic arrangement can be used to represent an odour in both countries, even if the odour-colour association for this odour differed. Methods The responses of 59 British and 60 French participants to the same set of odorants were compared. In the second part of the study, the ability of 'chromatic cards' to represent odours was tested. Those chromatic cards are objective coloured arrangements generated by a new patented scientific tool developed at Lorraine University (patent FR no. 1255688). This tool is based on a neural network algorithm for colour forecasting. It generates a chromatic card that represents any odour from its chemical composition and sensory description. In this study, participants were presented with three cards obtained from an analysis of lavender, cucumber and peppermint odours. First, the participants had to name the odour evoked by each card. Next, they selected from amongst three different olfactory stimuli the one that best matched each card. Results and Discussion Significant colour characterisations were observed for each and every one of the odours tested in both populations. Moreover, both commonalities and differences were reported between the two populations in terms of the odour-colour associations that they exhibited. The chromatic representations evoked the appropriate odour percept and were significantly associated to their related odours in both of the populations. Conclusions These findings highlight the existence of common colour representations of odours amongst French and British participants, though some differences were also found. Despite these differences, we were able to validate the relevancy of using single chromatic arrangements in both countries in order to communicate odour information. The latter result may open up the way for a number of potentially important applications in the design and marketing of both food and non-food products.

To characterize carcass and meat attributes, such as beef eating quality in specific farming conditions, 31 young grass-fed crossbred Angus x Salers cattle in two farming systems (a mono-cattle system versus a mixed system with beef cattle and sheep) were used in this study. Three muscle cuts (striploin—m. longissimus dorsi et thoracis; bolar blade—m. triceps brachii caput longum; internal flank plate—m. obliquus internus abdominis) were used for consumer eating quality testing and striploin was used for panelist eating quality assessment, and objective measurements [Warner–Bratzler shear force (WBSF) and fatty acid (FA) and antioxidant contents]. Results indicated that the farming system had no impact on carcass characteristics or meat quality, but it tended to affect FA content, which is likely explained by between-system differences in animal maturity (assessed by ossification score). Animal gender had significant effects on three eating quality traits evaluated by untrained consumers, with higher flavor liking, overall liking, and overall meat eating quality (MQ4) scores in females than in males. Additionally, FA contents were correlated with sensory quality traits to varying extents: consumer-scored tenderness, flavor, and overall liking were mainly positively correlated with ω-3 and ω-6 polyunsaturated fatty acid (PUFA) contents, and panelist-evaluated tenderness and abnormal flavor were more positively correlated with total lipids, saturated fatty acid (SFA), and monounsaturated fatty acid (MUFA) contents. Overall, this study showed that specific grass-fed crossbred Angus x Salers cattle can produce lean meat rich in ω-3 PUFAs with a low ω-6/ω-3 ratio and with “better than average” beef eating quality.
