Nutritional and Bioactive Characterization of Unconventional Food Plants for Su...
Oliveira, Izamara; Salgado, José Miguel R.T.; Lopes, João Krauspenhar; Carocho, Márcio; Silveira, Tayse F. F. da; Garcia, Vitor Augusto dos SantosUnconventional food plants (UFPs) are increasingly valued for their nutritional composition and bioactive potential. This study proposes a comprehensive characterization of the chemical and bioactive properties of Pereskia aculeata Miller (Cactaceae) (PA); Xanthosoma sagittifolium (L.) Schott (Araceae) (XS); Stachys byzantina K. Koch (Lamiaceae) (SB); and inflorescences from three cultivars of Musa acuminata (M...
The influence of magnesium and manganese cations on the chemical and bioactive ...
Oliveira, Izamara; Chrysargyris, Antonios; Finimundy, Tiane C.; Carocho, Márcio; Santos-Buelga, Celestino; Calhelha, Ricardo C.; Tzortzakis, NikolaosThis research investigated the effects of hydroponic cultivation with enriched concentrations of magnesium (+Mg), manganese (+Mn), a combination of +Mg and +Mn, or decreased concentrations of these minerals (control) on the nutritional, chemical, and bioactive attributes of purple and green basil. While Mn significantly increased the growth of purple basil and affected the composition of essential oil and miner...
Optimization and comparison of heat- and ultrasound-assisted extraction methods...
Albuquerque, Bianca R.; Pinela, José; Pereira, Carla; Calhelha, Ricardo C.; Oliveira, Izamara; Heleno, Sandrina A.; Oliveira, Beatriz; Barros, LillianThis study is aimed at maximizing the recovery of anthocyanins from Sicana odorifera fruit epicarp by heat- and ultrasoundassisted extraction (HAE and UAE, respectively) and at evaluating the in vitro bioactive properties of the anthocyanin-rich extracts obtained under optimized conditions. The optimization process utilized response surface methodology (RSM) through a central composite rotatory design (CCRD), c...
Chemical and bioactive characterization of Euterpe oleracea Mart
Oliveira, Izamara; Carocho, Márcio; Finimundy, Tiane C.; Pires, Tânia C.S.; Vaz, Josiana A.; Santos-Buelga, Celestino; Ferreira, Isabel C.F.R.Besides the economic factor, açaí has been highlighted for its nutritional value, but also for its richness in α-tocopherol (vitamin E), phenolic compounds and for having interesting bioactive potential1. Therefore, the objective of this work was to perform the chemical and bioactive characterization of freeze-dried açaí pulp. Organic acids were determined by HPLC-DAD, tocopherols by HPLC-fluorescence, and phen...
Comparison between different extraction methods in the recovery of bioactive mo...
Oliveira, Izamara; Heleno, Sandrina A.; Carocho, Márcio; Alves, Maria José; Vaz, Josiana A.; Dias, Maria Inês; Buelga, Celestino S.Melissa officinalis L., from the Lamiaceae family, is one of the most important medicinal and aromatic plants with potential in the market. With the passing of time, the use of medicinal plants in the treatment of some illness has gone from the simplest forms of local treatment to the industrial manufacture of phytotherapics. In addition to their medicinal effect, they can also be used in the form of infusions ...
Avaliação nutricional de subprodutos da indústria do biodiesel e sua importânci...
Oliveira, IzamaraAtualmente tem-se estimulado a busca por outras fontes de energia renováveis, uma dessas fontes é o biodiesel, porém a sua fabricação gera subprodutos chamados de tortas, as quais usualmente não possuem uma destinação eficientemente adequada. Estas por sua vez, oneram características nutricionais a serem inclusas em formulações de dietas para ruminantes. O objetivo foi caracterizar e determinar a qualidade nutr...
