“…PJ antioxidant activity was found to be three times higher than that of red wines and green teas, and from two‐ to sixfold stronger than other natural fruit juices such as apple, pineapple, cranberry, and orange . However, the phenolic content of PJ is strongly influenced by the cultivar and agronomical and climate conditions . Owing to their effect on health, innovative analyses methods have been used to detect bioactive phenolic compounds in different plant sources …”

The UHPLC-Orbitrap-MS approach was employed for the first time to identify the phenolic compound profiling in five pomegranate genotypes. TAA was analysed using an ABTS assay, and the results showed a significant variability in nutraceutical potential of the pomegranate genotypes studied. The inclusion of phenolic information in the linear discriminant analysis allowed very good discriminations among genotypes to be obtained. © 2018 Society of Chemical Industry.

“…Polyphenol profile of grape seed oil may be affected to a greater extent by other variables, such as a variety of grape seed and environmental growing conditions, rather than extraction procedures . Also, on the basis of our results, it can be assumed that the polyphenol profile of cold pressed grape seed oils depends on whether the grape seeds were under the influence of the fermentation and/or distillation process before pressing.…”

Various grape seed samples collected in wineries, as a by‐product before and after the fermentation process of pomace and after fermentation and distillation process of pomace, are used for oil extraction by cold pressing. Fatty acid profile, content and composition of tocopherols, content and composition of phenols, as well as the oxidative stability of oils are investigated. Obtained results show that cold pressed grape seed oils are characterized by different nutritional quality and oxidative stability, due to peculiar effects of the fermentation and distillation processes. Cold pressed oil obtained from cleaned and dried seeds of grapes after fermentation and/or distillation process is richer in bioactive compounds compared to the oil obtained from grape seeds without fermentation. On the other hand, the high temperature in distillation process of pomace has a negative effect on the content of some bioactive compounds and oxidative stability of oil from this waste material. Practical Applications: In this paper, different cold pressed grape seed oils are analyzed for nutritionally important compounds and oxidative stability. The results show that, depending on the source of grape seeds as waste material, the nutritional quality of the obtained oils differs. In the production of high quality cold pressed grape seed oil, seeds from different sources of waste should not be mixed. It is not recommended to use the seeds from the waste material after distillation process in the production of high quality cold pressed grape seed oil. Some chemical characteristics of cold pressed grape seed oils obtained from different winery waste are analyzed. The different waste materials have a pronounced effect on the quali‐quantitative profiles of bioactive compounds and induction period of oils. Obtained results show that cold pressed grape seed oils are characterized by different nutritional quality and oxidative stability, due to peculiar effect of fermentation and distillation processes. For production of high quality cold pressed oil, seeds from different winery waste material should not be mixed.

The primary objective of this study was to shed greater light on the characteristics and multifaceted potential of oil extracts from kernels of Bertholletia excelsa (Brazil nut), seeds of the Plukenetia species and Caryocar species. These are but a few of the multitude of the plant species found in the Amazon and Brazil's Cerrado biomes. They have many substantial organoleptic, nutritional, and functional properties that are comparable or exceed better known oils, and they manifest health benefits and prospective economic opportunities as an oil source for foods, pharmaceutical, and cosmetic industries. It is also hoped that this study gives rise to further research that may be beneficial to the industry and improve the local economies where these raw materials are found.
