Bioactive and phenolic profiles in Pinus pinaster Bark : a comparative study of...
Barros, Diana; Alonso-Esteban, José Ignacio; Finimundy, Tiane C.; Pereira, Carla; Vaz, Josiana A.; Pereira-Pinto, Ricardo; Fernandes, ÉliaThis study conducted a comprehensive comparison of two green extraction methods, microwave-assisted extraction (MAE) and ultrasound-assisted extraction (UAE), for recovering bioactive phenolic compounds from Pinus pinaster bark. The goal was to valorize timber industry waste and enhance the value of by-products through the development of eco-friendly processes to extract phenolic compounds from Pinus pinaster A...
The food (r)evolution: innovations for food quality, safety, and sustainability
Pinela, José; Alonso-Esteban, José IgnacioThe growing interest in sustainable foods is driving the use of underutilized sources such as macroalgae, agri-food by-products, acorns, and edible insects, combined with advanced extraction, processing, and preservation technologies. These approaches enable the development of functional foods and innovative ingredients, improve shelf life, nutritional value, and functionality, reduce waste and environmental im...
Hass Avocados Cultivated in the Canary Islands: Sensory Attributes Related to F...
Dorta, Eva; Alonso-Esteban, José Ignacio; Álvarez-Acosta, Carlos; Lobo, M. GloriaDry matter (DM) is a critical parameter for avocado quality and commercialization, particularly in the 'Hass' cultivar, where it is closely associated with the oil content and flavor. This study evaluated the fatty acid composition and sensory attributes of 'Hass' avocados with varying DM levels (19%, 21%, 24%, and 27%) cultivated in the Canary Islands. Additionally, the impact of dehydration methods (oven and ...
Exploring acorn shells: Phenolic composition and bioactive potential for sustai...
Mateus, Cristiano; Alonso-Esteban, José Ignacio; Finimundy, Tiane C.; Mandim, Filipa; Oliveira, Izamara; Babo, Pedro; Ferreira, Isabel C.F.R.Pedunculate (Quercus robur L.), holm (Quercus rotundifolia Lam.), and cork (Quercus suber L.) oaks are abundant across the Portuguese landscape. This study aims to evaluate the phenolic composition and bioactivities of acorn shell samples and determine their potential as a functional compound source. In total, five acorn shell samples collected in different locations and from different species were analyzed: Q....

Antioxidant Activity of Foods and Natural Products
Pinela, José; Dias, Maria Inês; Pereira, Carla; Alonso-Esteban, José IgnacioToday, there is growing recognition of the importance of antioxidants in promoting human health and well-being. These compounds play a vital role in protecting the organism from oxidative stress, which is implicated in the pathogenesis of various chronic degenerative diseases, including cardiovascular and neurodegenerative disorders, diabetes, and different types of cancer [1]. Furthermore, antioxidants serve a...
The chemical characterisation of the maritime pine bark cultivated in northern ...
Barros, Diana; Fernandes, Élia; Jesus, Meirielly; Barros, Lillian; Alonso-Esteban, José Ignacio; Pires, Preciosa; Vaz-Velho, ManuelaMaritime pine, scientifically known as Pinus pinaster, holds a vital role in Iberian Peninsula forests, primarily as a source of wood for panels, paper, and cellulose production. Recently, there has been a growing interest in utilising agroforestry by-products to yield valuable chemicals for applications in various sectors, including the food, pharmaceutical, and bioenergy industries. This study aimed to assess...
Nutrition security of hemp for human consumption
Iriondo-DeHond, Amaia; Alonso-Esteban, José Ignacio; Gallego-Barceló, Paula; García, Patricia; Abalo, Raquel; Castillo, Maria Dolores delNutrition security is a challenge of the XXI century for achieving a sustainable health. Hemp cultivation contributes to the European Green Deal objectives and is a potential solution for producing a more sustainable food chain and contributing to the nutrition security of the global population. Hemp, Cannabis sativa cultivars containing less than 0.2% of D9- tetrahydrocannabinol (THC), is a multipurpose crop w...

Chemical composition and biological activities of whole and dehulled hemp (Cann...
Alonso-Esteban, José Ignacio; Pinela, José; Ćirić, Ana; Calhelha, Ricardo C.; Soković, Marina; Ferreira, Isabel C.F.R.; Barros, LillianThis study aimed to determine a complete chemical composition of eight different varieties of whole hemp seeds and eight samples of commercial dehulled hemp seeds. We also evaluated the phenolic profiles and antioxidant, cytotoxic, and antimicrobial properties of hydromethanolic seed extracts. Whole hemp seeds contain much more fibre than dehulled hemp seeds, which contain more fat and protein. Sucrose and raff...
