Avaliação do desempenho de espalhadores de estrume na aplicação localizada de c...
Dias, António Bento; Dias, Ivo Lourenço; Falcão, José; Cruz, VascoSendo a compostagem de bagaço de azeitona com folhas de oliveira e estrume de ovinos ou bovinos uma técnica exequível ao nível da exploração agrícola, apenas será possível fechar o ciclo da economia circular com a sua aplicação no solo do olival. Tal requer que se disponha de tecnologia que garanta a colocação do composto à taxa pretendida no local desejado. Avaliou-se a utilização de dois semi-reboques distrib...
A new approach in PLS/TPS compatibilization using garlic oil: effect on morphol...
Castro, Maria Cidália Rodrigues; Rodrigues, Pedro António Veiga; Cruz, Vasco; Machado, A. V.The packaging industry has made efforts to reduce food waste and improve the resilience of food systems worldwide. Active food packaging, which incorporates active agents, represents a dynamic area where industry and academia have developed new strategies to produce innovative and sustainable packaging solutions that are more compatible with conventional options. Due to health and environmental concerns, indust...
Compatibilizer efficiency in enhancing marine plastic waste valorization throug...
Piedade Cestari, Sibele; Rodrigues, Pedro António Veiga; Ribeiro, Ana Cristina; Castro, Maria Cidália Rodrigues; Cruz, Vasco; Torres, Ana Rita OliveiraThis study investigated the optimal combination of compatibilizers and stabilizers to enhance the value of marine environment plastic (MEP). The composition of the plastics was analysed, and a simulated recycled plastic blend (sMEP) was prepared based on a simplified composition of actual MEP. Different concentrations of three commercial compatibilizers (C1, C2 and C3) were tested to improve tensile strength. T...

Censo Nacional de Coruja-das-torres (Tyto alba) 2023: relatório preliminar
Roque, Inês; Lourenço, Rui; Tomé, Ricardo; Leitão, Alexandre; Botelho, Ana; Santos, Carlos; Raposo, Daniel; Santos, Daniel; Realinho, EduardoA coruja-das-torres é uma ave de rapina noturna que apresenta atualmente uma tendência populacional negativa na Península Ibérica (GTAN-SPEA 2022, Escandel & Escudero 2021) e na Europa (BirdLife International 2021, Eionet 2022). Caça preferencialmente em áreas abertas, tais como campos agrícolas, pastagens e florestas pouco densas, evitando florestas densas e grandes extensões de matos. Ocupa também áreas urban...
Effect of pomegranate peels and extract in barrier, optical and mechanical prop...
Andrade, Mariana; Vilarinho, Fernanda; Rodrigues, Pedro; Barros, Carolina; Cruz, Vasco; Machado, Ana Vera; Barbosa, Cássia; Ramos, FernandoBeing more than 50 % of pomegranate (Punica granatum L.) constituted by non-edible parts, namely peels (50%) and seeds (10%), pomegranate is an excellent source of by-products. Its peels and seeds present excellent antioxidant and antimicrobial activities and a high content of phenolic compounds, namely ellagitannins. This work aimed to evaluate the mechanical and optical properties of two polylactic acid (PLA)...
Antioxidant and antimicrobial properties of PLA based active packaging with pom...
Andrade, Mariana; Rodrigues, Pedro; Barros, Carolina; Cruz, Vasco; Machado, Ana; Barbosa, Cássia; Coelho, Anabela; Furtado, Rosália; Correia, CristinaActive food packaging’ primary goal is to extend foodstuffs’ shelf life, through a dynamic and continuous interaction between the package and the packaged food. In an emission active packaging, the objective is the gradual release of antioxidant and/or antimicrobial compounds into the food surface, to delay the natural foods’ degradation. The active compounds can be extracted from several sources, such as aroma...

Andrade, Mariana A.; Rodrigues, Pedro V.; Barros, Carolina; Cruz, Vasco; Machado, Ana Vera; Barbosa, Cássia H.; Coelho, Anabela; Furtado, RosáliaThe search for new forms to extend foodstuffs’ shelf-life through the use of natural compounds and extracts continues to grow among researchers and the industry. In this line of thought, the main objective of this work was to develop, characterize and evaluate the effectiveness of an active food packaging based on polylactic acid (PLA) and incorporated with natural extracts obtained from grape and/or pomegranat...
