Valorization of Solanum melongena L. crop by-products: phenolic composition and...
Añibarro-Ortega, Mikel; Dias, Maria Inês; Petrović, Jovana; Núñez, Sonia; Calhelha, Ricardo C.; Costa, Eduardo M.; Machado, M.; Pintado, ManuelaThis study explored the valorization of post-harvest eggplant aerial parts as a sustainable source of value-added ingredients by investigating their phenolic composition and in vitro bioactive properties. HPLC-DAD-ESI/MSn analysis identified chlorogenic acid derivatives as the predominant phenolic compounds (53 % of the phenolic fraction), followed by O-glycosylated kaempferol and quercetin. The extract display...
Exploring the potential of underrated yet versatile crop Lunaria annua L.: New ...
Petrović, Jovana; Almeida, Daiana; Fernandes, Ângela; Stojković, Dejan; Robajac, Dragana; Silveira, Tayse Ferreira; Barros, LillianLunaria annua is an underexplored crop with promising potential for use in various industries: food, oil etc. It grows rapidly, has low maintenance and high resistance to pathogens, which makes it a promising crop for sustainable cultivation. Herein, we investigated nutritional value, phenolic profile, and bioactive properties of L. annua seeds collected in the wild. The results we obtained indicate that seeds ...
Nutrients, Phytochemicals, and In Vitro Biological Activities of Goldenberry (P...
Añibarro-Ortega, Mikel; Dias, Maria Inês; Petrović, Jovana; Mandim, Filipa; Núñez, Sonia; Soković, Marina; López, Víctor; Barros, Lillian; Pinela, JoséThis study provides a comprehensive characterization of Physalis peruviana L., covering the nutritional composition of the fruit and the phytochemical profiles and in vitro bioactive properties of berry and calyx extracts. The fresh fruit stood out as a source of dietary fiber (5.16 g/100 g) and is low in fat (0.49 g/100 g). A 100-g serving also contained notable amounts of ascorbic acid (32.0 mg), tocopherols ...
Phenolic composition and in vitro bioactive and enzyme inhibitory properties of...
Añibarro-Ortega, Mikel; López, Víctor; Núñez, Sonia; Petrović, Jovana; Mandim, Filipa; Barros, Lillian; Soković, Marina; Ferreira, Isabel C.F.R.The phenolic composition and bioactive properties of Holland and Italian bell pepper plant (Capsicum annuum L.) hydroethanolic extracts were investigated by HPLC-DAD-ESI/MS and in vitro cell- and enzyme-based assays, respectively. O-Glycosylated luteolin derivatives were identified as the major compounds, representing -60% of the phenolic fraction. Both extracts displayed remarkable antioxidant activity and abi...
Biochemical Composition of Pumpkin Seeds and Seed By-Products
Polyzos, Nikolaos; Fernandes, Ângela; Calhelha, Ricardo C.; Petrović, Jovana; Soković, Marina; Ferreira, Isabel C.F.R.; Barros, LillianThe goal of the current work was to assess the nutritional profile and phytochemical properties of cucurbit (Cucurbita maxima L.) seeds, seed oils and oil extraction by-products (e.g., seed-cakes). Our results suggest a high nutritional value for both cucurbit seeds and cucurbit cake, while γ-tocopherol was the richest compound, with traces of α, β and δ-tocopherol compounds also detected. Regarding the free su...
Effects of the extraction techniques on the chemical composition and bioactive ...
Oliveira, Izamara; Chrysargyris, Antonios; Heleno, Sandrina A.; Carocho, Márcio; Calhelha, Ricardo C.; Dias, Maria Inês; Petrović, JovanaThe present study aims to determine the combined effect of cropping system and irrigation regime on the chemical composition and bioactive properties of lemon balm aerial parts. For this purpose, lemon balm plants were grown under two farming systems (conventional farming vs organic farming) and two irrigation levels (full irrigation vs deficit irrigation) and harvested twice throughout the growing period. The ...
Valorization of rambutan (Nephelium lappaceum L.) peel: chemical composition, b...
Albuquerque, Bianca R.; Pinela, José; Dias, Maria Inês; Pereira, Carla; Petrović, Jovana; Soković, Marina; Calhelha, Ricardo C.; Oliveira, BeatrizChemical constituents and bioactive properties of rambutan (Nephelium lappaceum L.) peel were characterized and heat-/ultrasound-assisted extractions (HAE/UAE) of anthocyanins were optimized by response surface methodology. Five organic acids, the alpha-, gamma-, and delta-tocopherol isoforms, and twenty-five fatty acids (36.8 % oleic acid) were identified, as well as a phenolic profile composed of ellagitannin...
Combined effect of biostimulants and mineral fertilizers on crop performance an...
Fernandes, Ângela; Polyzos, Nikolaos; Mandim, Filipa; Pereira, Carla; Petrović, Jovana; Soković, Marina; Petropoulos, Spyridon Α.The aim of the present study was to evaluate the possible effects of two different biostimulant formulations at different application regimes and combined or not with mineral fertilizers (e.g., W1–W8, including the control treatment (no formulations added)) on the yield parameters and fruit quality of watermelon plants. The highest yield was recorded for the W5 treatment due to the formation of more fruit. The ...
Comparative evaluation of physicochemical profile and bioactive properties of r...
López-Hortas, Lucía; Caleja, Cristina; Pinela, José; Petrović, Jovana; Soković, Marina; Ferreira, Isabel C.F.R.; Torres Perez, Maria DoloresDehydration of the edible seaweed Chondrus crispus was performed by freeze-drying, conventional oven-drying and emerging microwave hydrodiffusion and gravity (MHG). In this work, the drying kinetics and modelling, estimating specific energy consumption and environmental impact of distinct processes were tested. Color and microstructural features of the dried macroalgae were also evaluated, as well as their nutr...
Solanaceae crop by-products as renewable sources of bioactive phenolic extracts
Añibarro-Ortega, Mikel; Petrović, Jovana; Dias, Maria Inês; Pereira, Alexis; Soković, Marina; Ferreira, Isabel C.F.R.; Prieto Lage, Miguel A.The upcycling of agri-food by-products into high added-value products has been promoted in recent years. Solanaceae is one of the main plant families supplying important vegetable and staple food crops worldwide. Bell pepper (Capsicum annuum L.) and eggplant (Solanum melongena L.) are two good examples, and their agricultural production generates million tons of valueless crop remains (especially plant aerial p...
