Squashes and pumpkins are important dietary sources of carotenoids worldwide. The carotenoid composition has been determined, but reported data have been highly variable, both qualitatively and quantitatively. In the present work, the carotenoid composition of squashes and pumpkins currently marketed in Campinas, Brazil, were determined by HPLC-DAD, complemented by HPLC-MS for identification. Cucurbita moschata 'Menina Brasileira' and C. moschata 'Goianinha' had similar profiles, with beta-carotene and alpha-carotene as the major carotenoids. The hybrid 'Tetsukabuto' resembled the Cucurbita pepo 'Mogango', lutein and beta-carotene being the principal carotenoids. Cucurbita maxima 'Exposição' had a different profile, with the predominance of violaxanthin, followed by beta-carotene and lutein. Combining data from the current study with those in the literature, profiles for the Cucurbita species could be observed. The principal carotenoids in C. moschata were beta-carotene and alpha-carotene, whlereas lutein and beta-carotene dominate in C. maxima and C. pepo. It appears that hydroxylation is a control point in carotenoid biosynthesis.

The study aimed to evaluate the effect of ultrasound maceration of cold-pressed oils with freeze-dried mullein flowers (Verbascum thapsus L.) on their oxidative stability and chemical composition. After the maceration process, oils' were subjected to their oxidative stability (80-120 °C) and their chemical composition, Moreover, oils kinetics parameters were calculated.

The solid waste generated from processing rosehip fruits into jam is valuable due to its rich content in fibres, polyphenols, and carotenoids; it could be valorised as a functional ingredient in a powder form to enrich food products. This study aimed to test its potential as a value-added ingredient, especially to enrich waffle cones with fibres, polyphenols, and carotenoids. In this regard, four formulations of waffle cones were prepared by partially substituting wheat flour with rosehip waste powder at 0%, 10%, 15%, and 20%, reaching concentrations of 0%, 3.
