Samples of rapeseed oil obtained by cold pressing from seeds treated with an electrostatic field of intensity E = (0.05-0.25) MV·m ⁻¹ for a duration of t = 3-30 s were analyzed. As a reference, the spectral-luminescent characteristics of rapeseed oil samples prepared similarly from control rapeseed that had not been treated with an electrostatic field were also recorded. The behaviour of rapeseed oil fluorophores, namely tocopherol, phenol, fatty acids, oxidation products, vitamins and pigments, which are part of its composition, was a source of information about the chemical composition of the seeds under study. It has been found that the fluorophores in rapeseed oil obtained from seeds pretreated with an electrostatic field with an intensity at E = (0.05-0.25) MV·m ⁻¹ for t = 3-30 s exhibit spectral-luminescent properties identical to those of rapeseed oil obtained from seeds that were not subjected to additional electrostatic field treatment. Specifically, the spectral-luminescent properties of the fluorophores in rapeseed oil (tocopherol, phenol, fatty acids, oxidation products, vitamins, and pigments) obtained from seeds treated with an electrostatic field with an intensity at E = (0.05-0.25) MV·m ⁻¹ for t = 3-30 s were identical to those of fluorophores in rapeseed oil obtained from rapeseed that had not been exposed to an electric field of the specified parameters. The results obtained indicate that additional cleaning of rapeseed using an electrostatic field under the specified conditions does not cause any changes in its chemical composition or in the nature of intermolecular interactions within it.

Research on sustainable consumption has identified gender-related differences in environmental attitudes and consumer preferences, yet evidence regarding the magnitude and consistency of these differences remains mixed across cultural contexts. Poland provides a relevant context for examining these patterns in a Central European consumer market undergoing environmental and energy-related transitions. This study examines whether women and men differ in the perceived importance of purchasing criteria and in selected pro-environmental attitudes related to energy-efficient and environmentally friendly everyday products. The CAWI survey was conducted among 1068 adult respondents recruited by an external research provider, using a non-probability sample with equal representation of women and men. Gender differences were initially assessed using the Mann–Whitney U test with Holm’s correction and effect size estimation, supplemented by multiple correspondence analysis (MCA) and Spearman’s rank correlation. Price and ingredient quality received the highest ratings in both groups, indicating significant similarity between women and men. After Holm’s correction, four gender differences remained statistically significant in unadjusted comparisons. Additional robustness analyses, controlling for age group, financial situation, employment status, and place of residence, showed that only two associations remained statistically stable: women reported greater concern about climate change and attributed greater importance to cruelty-free products. Overall, the observed gender differences were small and selective, and gender accounted for only a very small part of the multivariate response structure. The results therefore suggest that the overall similarity between women and men is greater than the magnitude of the observed differences and caution against treating gender as a strong, stand-alone basis for explaining or segmenting consumer environmental preferences.
