Microwave-assisted extraction for the sustainable recovery and valorization of ...
Barros, Diana; Pereira Pinto, Ricardo; Fernandes, Élia; Pires, Preciosa; Vaz-Velho, ManuelaThis study investigates the potential of Pinus pinaster subsp. atlantica bark, a forestry byproduct fromnorthernPortugal, as a source of phenolic compoundswithstrongantioxidant properties. Microwave-assisted extraction (MAE) was used to optimize recovery, assessing the effects of solvent composition (water, ethanol, and 50:50 water–ethanol), extraction time (15 or 30 min), and temperature (90, 110, or 130 ◦C) u...
Correlation of antioxidant and antibacterial activities of the aqueous Pinus pi...
Barros, Diana; Grenho, Liliana; Fernandes, Maria Helena; Gomes, Pedro Sousa; Fernandes, ÉliaThis study explores the antioxidant, antibacterial, and cytocompatibility properties of aqueous Pinus pinaster bark extract (PBE). PBE was prepared using two solvent systems—100% distilled water and 1% DMSO in aqueous solution—at a solid-to-liquid ratio of 1:20 (w/v), following ISO guidelines. Extract characterization included yield determination, FTIR analysis, quantification of total phenolic (TPC) and flavon...
Valorisation of Atlantic bonito and Brassica by-products in the development of ...
Solinho, Joana; Machado, Sofia; Pereira-Pinto, Ricardo; Barros, Diana; Vaz-Velho, Manuela; Vazquez, Manuel; Pinheiro, RitaFish is a highly nutritious food, rich in protein, unsaturated fats, vitamins, and minerals, and its consumption has increased due to the associated health benefits. However, fish processing generates substantial waste, accounting for more than 50% of the total weight of the fish, leading to economic losses. Utilising these byproducts presents an opportunity to reduce waste while enhancing the nutritional profi...

EU citizens’ perception of risks posed to the sustainability of EU food security
Mata, Fernando; Barros, Diana; Pereira-Pinto, Ricardo; Pires, PreciosaFood security is a core global sustainability challenge and priority of the UN Sustainable Development Goals. Events like COVID-19, extreme weather, and global conflicts have significantly impacted food prices, as evidenced by the FAO food price index rising from 95.1 in 2019 to 143.7 in 2022, heightening EU food security concerns. The European Commission responded with a food supply contingency plan. According...
Assessing boar taint in portuguese pork: a small-scale study of prevalence and ...
Pereira-Pinto, Ricardo; Barbosa, Carla; Mata, Fernando; Reis, Núria; Barros, Diana; Vaz-Velho, ManuelaAim of study: To assess the boar taint prevalence in the Portuguese pork industry through an observational study model by measuring skatole and androstenone levels in fat and to compare it with the estimated thresholds for these compounds among Portuguese consumers. Area of study: Portugal. Material and methods: Adipose tissue samples from 140 animals (102 entire males and 38 females) were collected in three Po...
Enhancing storage stability of smoke-flavored horse mackerel filets using natur...
Barros, Diana; Nova, Paulo; Cunha, Sara; Monteiro, Vitor; Fernandes, Élia; Pereira-Pinto, Ricardo; Barbosa, Carla; Pintado, Maria; Gomes, AnaThe Atlantic horse mackerel (Trachurus trachurus) is a globally favored fish due to its abundance, nutritional value, and aordability, but it faces quality preservation challenges. To address this, this study aimed to enhance its value by creating low-salt smoked products with natural bioactive compounds from seafood and forest sources. The fish filets were divided into four groups: one as a control, and the ot...
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...
Application of pine bark extracts on ready-to-eat smoked pork belly: effects on...
Pereira-Pinto, Ricardo; Barros, Diana; Vaz-Velho, ManuelaNatural foods with increased nutritional content and additional biological and health benefits are appealing to modern customers. A growing interest in using natural substances to replace synthetic compounds in foods has sparked several thorough studies with plant-origin products. Maritime pine bark (Pinus pinaster subsp. atlantica) is an abundant waste from the timber industry and an important source of natura...
