Effect of Different Seasons and Development Stages on the Chemical Composition ...
Mandim, Filipa; Carocho, Márcio; Petropoulos, Spyridon Α.; Santos-Buelga, Celestino; Barros, LillianCynara cardunculus L. (cardoon) is a wild species of the Mediterranean basin and is highly appreciated due to its rich nutritional value and versatile industrial applications. It is widely known that environmental conditions, such as air temperature, humidity, and solar radiation, among others, play a crucial role in plant phenological variations and the chemical composition and bioactive properties of differen...
Novel cold and thermally pasteurized cardoon-enriched functional smoothie formu...
Mandim, Filipa; Petropoulos, Spyridon Α.; Pinto, Carlos A.; Heleno, Sandrina A.; Rodrigues, Paula; Dias, Maria Inês; Saraiva, Jorge A.This study investigated the potential of incorporating cardoon ( Cynara cardunculus L.) blades as bioactive and dietary fiber ingredients in vegetable/fruit-based smoothies, within a zero-waste approach. The smoothie formulations were pasteurized by high-pressure (550 MPa for 3 min, HPP) and thermal (90 degrees C for 30 s, TP) treatments and stored at 4 degrees C for 50 days. Cardoon-fortified smoothies exhibit...
The Impact of Deficit Irrigation on the Agronomic Performance and Chemical Comp...
Polyzos, Nikolaos; Paschoalinotto, Beatriz H.; Pires, Tânia C.S.P.; Añibarro-Ortega, Mikel; Calhelha, Ricardo C.; Ferreira, Isabel C.F.R.In the current study, the effects of drought stress on the growth and phytochemical profile of Scolymus hispanicus L. (a.k.a. golden thistle) were evaluated. Plants were treated with three irrigation regimes, e.g., plants that received only rainwater (Control; C), deficit irrigation (I1; 50% of field capacity (FC)), and full irrigation (Ι2; 100% of FC). The fresh weight of the rosette of leaves was not negative...
How Does Domestic Cooking Affect the Biochemical Properties of Wild Edible Gree...
Liava, Vasiliki; Fernandes, Ângela; Reis, Filipa S.; Finimundy, Tiane C.; Mandim, Filipa; Pinela, José; Stojković, Dejan; Ferreira, Isabel C.F.R.Wild edible greens are a key ingredient of the so-called Mediterranean diet and they are commonly used in various local dishes in their raw or processed form. Domestic processing of edible greens may affect their nutritional value and chemical profile. In this work, six wild species (e.g., Cichorium spinosum L. (S1); Centaurea raphanina subsp. mixta (DC.) Runemark (S2); Picris echioides (L.) Holub (S3); Urosper...
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...
The wide spectrum of industrial applications for cultivated cardoon (Cynara car...
Mandim, Filipa; Santos-Buelga, Celestino; Ferreira, Isabel C.F.R.; Petropoulos, Spyridon Α.; Barros, LillianCynara cardunculus L. var. altilis DC. belongs to the Asteraceae family and is widely used. This species is integrated into the Mediterranean diet and has broad applicability due to its rich chemical composition. Its flowers, used as a vegetable coagulant for gourmet cheese production, are rich in aspartic proteases. Leaves are rich in sesquiterpene lactones, the most abundant being cynaropicrin, while stems pr...
Editorial: Rediscovering local landraces: shaping horticulture for the future, ...
Petropoulos, Spyridon Α.; Barros, Lillian; Ferreira, Isabel C.F.R.The ongoing climate change accompanied by weather extremes has increased uncertainty in the crop production sector, with a severe impact on yield and quality of crops (FAO, 2022). Moreover, the increasing world population, along with the continuous reduction of available irrigation water and agricultural land degradation due to anthropogenic activities, necessitates the redesign of the existing farming systems ...
Improved recovery of antioxidant compounds from refined pumpkin peel extract: a...
Mansour, Rim Ben; Falleh, Hanen; Nefzi, Nermine; Dakhlaoui, Sarra; Selmi, Sawssen; Hammami, Majdi; Barros, Lillian; Petropoulos, Spyridon Α.This study employed the mixture design method to determine optimal solvent combinations, aiming to obtain refined extracts from squash peels with enhanced antioxidant properties. We optimized extraction solvents, focusing on recovering the total phenolic compounds (TPC) and increased antioxidant properties using a second-order polynomial equation through the response surface methodology (RSM). Six solvents (MeO...
The use of response surface methodology to optimize assisted extraction of bioa...
Ben Mansour, Rim; Falleh, Hanen; Hammami, Majdi; Barros, Lillian; Petropoulos, Spyridon Α.; Tarchoun, Neji; Ksouri, RiadhThis work aimed to optimize the extraction conditions of bioactive compounds obtained from three squash by-products (e.g., peel, endocarp, and seeds) using the response surface methodology (RSM). The selected independent variables were ethanol concentration, extraction time, and extraction temperature. Squash by-products' bioactive molecules were extracted according to the matrix proposed by the experimental pl...
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 ...
