Development of a new eco-friendly ultrasound-assisted extraction method to quan...
López, Alejandro R.; Ortega-Caneda, Elena; Espada-Bellido, Estrella; Chinchilla, Nuria; Palma, Miguel; Aliaño González, María JoséBioactive compounds in food offer health benefits by influencing cellular and physiological functions. Tryptophan, an essential amino acid and precursor to neurotransmitters like melatonin and serotonin, regulates mood and circadian rhythms. However, its quantification in mushrooms is scarce studied. An eco-friendly ultrasound- assisted extraction (UAE) method has been optimized to quantify tryptophan using ult...
On the valorization of Arbutus unedo L. Pomace: Polyphenol extraction and devel...
Duarte, Hugo; Carrera, Ceferino; Aliaño-González, M.J.; Gutiérrez-Escobar, Rocío; Jiménez-Hierro, María Jesús; Palma, Miguel; Galego, LudovinaThe fruits of Arbutus unedo L. have a crimson colour and are enriched with remarkable concentrations of bioactive compounds such as anthocyanins and polyphenols. These fruits are commonly used in the production of a Portuguese Protected Geographical Indication distillate called “Aguardente de Medronho”. During this process, a solid pomace is generated and presently discarded without valuable applications. In th...
Enhancing efficiency of enzymatic-assisted extraction method for evaluating bio...
Tizón Alba, Ainara; Aliaño-González, M.J.; Palma, Miguel; Fernández Barbero, Gerardo; Carrera, CeferinoThe present investigation endeavors to optimize a method based on enzyme-assisted extraction for the efficient retrieval of bioactive compounds from mulberry, leveraging its notable health-promoting properties. A combined approach of Plackett-Burman design followed by Box-Behnken design was employed for determining the crucial extraction parameters and subsequently, refining the process. Optimal conditions cons...
Enhancing anthocyanin extraction from wine lees: a comprehensive ultrasound-ass...
Umsza-Guez, Marcelo A.; Vázquez-Espinosa, Mercedes; Chinchilla, Nuria; Aliaño-González, M. J.; Oliveira de Souza, Carolina; Ayena, KodjoviWine lees, an important by-product of the wine industry, pose a major environmental problem due to the enormous quantities of solid-liquid waste that are discarded annually without defined applications. In this study, the optimization of a method based on a Box-Behnken design with surface response has been carried out to obtain extracts with high anthocyanin content and potent antioxidant activity. Six variable...
Optimization of an Enzyme-Assisted Extraction Method for the Anthocyanins Prese...
Alavarsa-Cascales, Diego; Aliaño-González, M.J.; Palma, Miguel; Barbero, Gerardo F.; Carrera, CeferinoSeveral investigations have proven the presence of anthocyanins in different parts of acai plants. These compounds are responsible for the notable therapeutic properties of acai such as antioxidant, antimicrobial, anti-inflammatory, anticancer, and anticonvulsant. We have therefore optimized an enzyme-assisted extraction method for the anthocyanins found in acai, to be subsequently applied in many fields such a...
Ultrasound-assisted extraction of betalains from opuntia fruit pulp of differen...
Vázquez-Espinosa, Mercedes; González-de-Peredo, Ana V.; Carrera, Ceferino; Palma, Miguel; Barbero, Gerardo F.; Aliaño-González, M.J.Betalains are water-soluble pigments that have exhibited important pharmacological properties such as antioxidant, anticancer, antilipidemic and antimicrobial activity. These compounds have been isolated in numerous purple plants or fruits, as is the case of the wild species under the Opuntia genus. The fruits of these species are often disregarded because of their small size as well as the frequent presence of...
Avaliação da rega em olival em sebe com base em sondas de capacitância e imagen...
Palma, MiguelO presente estudo teve como objetivo realizar uma análise à gestão da rega num olival em sebe, através da comparação da condução de rega utilizada nos anos de 2019 e 2020, tendo por base a informação fornecida por sondas de capacitância e imagens NDVI obtidas por satélite, e da produção obtida nestes dois anos Procedeu-se, numa fase inicial, à descrição da área de estudo, da cultura nela existente, do tipo de s...
Empatia – Ferramenta Pró-Social Explorada num Grupo Terapêutico
Graça, João; Palma, Miguel; Mendonça, Carina; Cargaleiro, Inês; Melo, João CarlosIntrodução: A empatia é um conceito multidimensional que engloba a capacidade de inferir um estado emocional e responder a emoções vivenciadas pelo outro, podendo ser assim categorizada em empatia cognitiva e emocional. É uma capacidade que se desenvolve precocemente através, sobretudo, da interação com as figuras parentais. Não é exclusiva dos seres humanos e tem sido conservada evolutivamente, const...
