ABSTRACT An improved analytical strategy based on the QuEChERS extraction method combined with highperformance liquid chromatography with diode array detector (HPLC-DAD) was developed and validated for the first time for piceatannol determination in passion fruit seeds. The method showed a limit of quantification of 160 mg kg1 , good linearity (r2 ¼ 0.9957), recoveries in the range of 82?102% with good precision (RSD < 9%) and low matrix effect (þ17%). The new method was successfully applied for piceatannol determination in four passion fruit seeds species: Passiflora edulis Sims ?Flavicarpa,? P. edulis ?Sims,? Passiflora allata Curtis, and Passiflora ligularis Juss; for the last two species for the first time. Among them, the higher amounts of piceatannol were found in the seeds of P. allata Curtis and P. edulis ?Sims?: 20.8 ± 0.4 and 14.6 ± 0.2 mg kg1, respectively. Antioxidant activity was also evaluated and, in general, the antioxidant potential was stronger the higher the piceatannol concentration in the passion fruit seeds extracts. The obtained results highlight that passion fruit seeds are a rich source of piceatannol, boosting new applicability for these by-products, and indicating that the QuEChERS method is a powerful analytical strategy for piceatannol determination. |

Several socio-demographic factors influence fish consumption frequency and preferences in the Brazilian aquaculture market. Hence, the aims of this paper were (i) to acquire information on fish consumption frequency; (ii) to examine the associations between specific socio-demographic characteristics of aquaculture consumers; (iii) to investigate the consumption frequency of these specific characteristics relating to certain barriers and drivers of consumption frequency; and (iv) to explore whether consumption behavior varies across different groups of consumers and regions. The study involved an online survey of 1509 consumers across the five regions in Brazil. The results of this study indicated that the general fish consumption frequency pattern is highly seasonal. In addition, we determined that significant differences in fish consumption frequency, determinants, and habits were found among income levels, age groups and regions. Our results show that low-income consumers are highly disadvantaged and more likely to consume fish less frequently than the other income groups. We further recommend several marketing strategies and initiatives to stimulate the consumption frequency of fish amongst Brazilian consumers. |
