Enhancing carob flour (Ceratonia siliqua L.) for by-product utilization in food...
Vilas-Boas, Ana Martins; Brassesco, María Emília; Quintino, Andreia C.; Medronho, Bruno; Vieira, Margarida C.; Brandão, Teresa R. S.The focus on by-product valorization in the food industry, particularly from the carob pod, underscores a commitment to sustainability and resource efficiency. This fruit, sourced from the leguminous evergreen carob tree (Ceratonia siliqua L.), is renowned for its adaptable flavour and nutritional value, in Mediterranean regions such as Portugal. Its production yields significant by-products, presenting environ...

Edible films with protein and bioactive compounds from arthrospira sp.
Martins, Valter F. R.; Poças, Fátima; Pintado, Manuela; Morais, Rui M. S. C.; Morais, Alcina M. M. B.Arthrospira sp. is an alternative source of protein in the food chain, but it may also be considered a source of phenolic compounds with interesting properties, such as antioxidant and antimicrobial properties. In active packaging, these two properties are essential. In the present work, two extracts were produced: one extract rich in protein and another in bioactives. These two extracts were used in the produc...
A full insight into the valorization of wheat by-products
Ferreira, Daniela Marisa; Coscueta, Ezequiel; Brassesco, María Emília; Pintado, ManuelaWheat is one of the most consumed cereals globally, significantly contributing to human nutrition [1]. However, wheat processing generates underutilized by-products, primarily wheat germ and bran, despite their high nutritional value [2][3]. Wheat bran (WB) is a primary source of dietary fiber, proteins, and phenolic compounds and contributes to approximately 25% of the total weight of the wheat grain [4]. Ther...
Supercritical fluid extraction of polyphenols from almond oil industry by-produ...
Spréa, Rafael Mascoloti; Rodrigues, Daniele B.; Brassesco, María E.; Pintado, Manuela; Santoyo, Susana; Arranz, Elena; Prieto, Miguel A.Supercritical fluid extraction (SFE) has emerged as an advanced green technology for the recovery of bioactive compounds, offering enhanced extraction efficiency while eliminating the need for toxic organic solvents. In this context, industrial residues from almond oil production were subjected to CO? SFE by ISANATUR (Navarra, Spain), a company specializing in by- product valorization. Specifically, almond pres...
A new vision upon hemodialysis: a shift from synthetic to sustainable chitosan ...
Martingo, Maria Lima; Baptista-Silva, Sara; Pintado, Manuela; Borges, SandraThe article provides a comprehensive review of chronic kidney disease (CKD), covering its epidemiology, pathophysiology, diagnosis, and management. It highlights CKD's increasing prevalence globally and its significant impact on public health due to its association with cardiovascular diseases and progression to end-stage kidney disease. The article delves into the diagnostic criteria, including the use of glom...
Breaking the virus: yeast glucans as an effective alternative to acyclovir in H...
Tavares-Valente, Diana; Moreira, Helena; Sousa, Pedro; Amorim, Manuela; Conde, António; Pintado, Manuela; Fernandes, João; Azevedo-Silva, JoãoGlucans, structural polysaccharides in the yeast cell wall, are known for their biological and immunomodulatory capacities, helping in prevention and management of infections. Herpes simplex virus type 1 (HSVI) is a prevalent infection that causes great comorbidity and is challenging to treat due to the adverse effects of standard antiviral drugs like acyclovir. This study assessed the potential of yeast glucan...
Inclusion of pineapple by-products as natural antioxidant sources in diets for ...
Pereira, Ricardo; Basto, Ana; Pintado, Manuela; Valente, Luisa M. P.; Velasco, CristinaThis study investigates the effects of pineapple by-products on feed preservation during storage at two different temperatures (25 °C and 4 °C) and on European sea bass (Dicentrarchus labrax) stress resistance. Four isoproteic, isolipidic, and isoenergetic diets were manufactured: CTRL—negative control, commercial diet without added antioxidants; VITE—positive control, CTRL diet with 100 mg kg−1 of vitamin E; a...
Exploring the effects of sweet potato leaves on skin health - from antimicrobia...
Machado, Manuela; Silva, Sara; Pintado, Manuela; Costa, Eduardo M.Sweet potato leaves (SPL), an agricultural byproduct, hold significant potential in dermatological applications due to their bioactive compounds. This study evaluates the phenolic profile of SPL extracts and investigates their biological activities relevant to skin health. Extract fingerprinting, through uHPLC-DAD and LC–MS, identified phenolic acids and flavonoids, with cynarin, neochlorogenic acid, and spirae...
Exploring the potential of mealworm chitosan for hemodialysis applications
Martingo, Maria; Baptista-Silva, Sara; Mesquita, Raquel; Ferreira, João Paulo; Borges, Sandra; Pintado, ManuelaThis study introduces a sustainable and efficient alternative to traditional chitosan sources derived from crustaceans, exploring the extraction and application of insect-derived chitosan from Tenebrio molitor for hemodialysis (HD) membranes design. Efficient extraction and deacetylation methods were tested and developed between 6 h and 12 h to obtain chitosan. Chitin was isolated from T. molitor through deprot...
