Mushroom-derived polysaccharides as bioactive agents for skin regeneration: eva...
Fernandes, A.; Lopes, A.; Magalhães, R.; Oliveira, C.; Pintado, M.; Tavaria, F.Mushroom polysaccharides have emerged as promising bioactive agents for enhancing skin regeneration. This study evaluates three polysaccharide-rich fractions (SB, SC, RD) obtained by hot water and alkaline extractions from Coriolus versicolor, Pleurotus ostreatus, and Hericium erinaceus. Their potential to promote skin repair was investigated by analyzing effects on cell proliferation and migration, immune modu...
Protein hydrolysates from Tenebrio molitor and Hermetia illucens as novel food ...
Leal, D.; Borges, S.; Almeida, A.; Pintado, M.; Fonseca, A. J. M.; Cabrita, A. R. J.There has been a growing interest in insect meals as a sustainable alternative protein source for animal food and feed. In parallel, insect hydrolysates have been investigated in vitro for their bioactive properties, but the impact of dietary inclusion on dog’s nutritional parameters needs to be elucidated. This study aimed to evaluate the chemical composition and bioactive properties of four insect hydrolysate...
Impact of feeding a new sustainable insect hydrolysate to adult Beagle dogs on ...
Leal, D.; Barroso, C.; Fontes-Sousa, A. P.; Borges, S.; Maia, M. R. G.; Almeida, A.; Pintado, M.; Fonseca, A. J. M.; Cabrita, A. R. J.Introduction: In recent years, there has been increasing attention on sustainable protein sources for both food and feed, leading to a growing interest in edible insects. However, the potential impact of their bioactive properties on health remains limited. This study aimed to address this gap by investigating the effects of dietary inclusion of Hermetia illucens (BSF) hydrolysates on diet palatability, nutrien...
Antimicrobial activity of organic acids against some common food spoilage and p...
Sorathiya, K.; Melo, A.; Rodrigues, C.; Paulico, L.; Barracosa, R.; Correia, D.; Pintado, M.Background: In recent years, the food industry is challenged to produce high-quality products using natural preservative alternatives instead of synthetic ones, owing to the increasing consumer demand for clean-label food products. Organic acids have potential as an alternative due to their antimicrobial activity and high food safety (GRAS). Therefore, the objective of this work was to investigate the antimicro...
Edible coatings with polysaccharides and bioactive compounds from exhausted oli...
Martins, V.; Lopes, A.; Pintado, M.; Morais, R. M. S. C.; Morais, A. M. M. B.Introduction: Exhausted or delipidified olive oil pomace (EOP) is a by-product generated from the olive pomace after air drying and hexane extraction of residual oil [1]. This by-product is rich in phenolic compounds, such as hydroxytyrosol, tyrosol and catechol, with associated properties: antioxidant, antimicrobial, anti- inflammatory, anti-diabetic, anti-carcinogenic and anti-HIV [1, 2]. Coatings and films a...
Alga Fucus sp. extracts to produce edible films
Martins, V.; Machado, M.; Costa, E.; Gomes, A. M.; Poças, F.; Pintado, M.; Morais, R. M. S. C.; Morais, A. M. M. B.Introduction: Macroalgae are a good source of nutrients, such as carbohydrates (dietary fiber and polysaccharides), proteins, lipids and minerals [1,2]. Fucus sp. is composed of valuable bioactive compounds, such as fucoxanthin, vitamins, water-soluble (vitamin C and of complex B) and fat-soluble (vitamins A, D, E and K), phenolic compounds, lipids (MUFA and PUFA), and polysaccharides (fucoidans and alginic aci...
Byproducts as sources of phenolic compounds for functional textiles
Afonso, T. B.; Bonifácio-Lopes, T.; Costa, E. M.; Pintado, M.Introduction: The textile industry is a major global source of pollution due to its high use of energy, water and chemicals. Thus, a need has risen to move the textile industry towards a sustainable circular economy. The awareness of eco-safety and increased environmental concern has led to the use of green and sustainable natural dyes as the needed trend within this industry. Wastes/byproducts from the agri-fo...
Antimicrobial activity of potential essential oils to replace potassium sorbate...
Melo, A.; Sorathiya, K.; Rodrigues, C.; Paulico, L.; Barracosa, R.; Pintado, M.Introduction: In recent years, the food industry has faced the challenge of producing high-quality products using natural preservative alternatives instead of synthetic ones. Essential oils (EO), naturally present in various plants, have potential as alternatives due to their antimicrobial activity and high food safety (Generally Recognized as Safe, GRAS). This study aimed to investigate the antimicrobial activ...
Inflammatory potential of high-protein hybrid yogurt
Gigante, M. L.; Baptista, D. P.; Silva, K. K. P.; Machado, M.; Costa, E.; Pintado, M.Introduction: Partly replacing dairy proteins with plant proteins in processed foods is a potential alternative strategy for creating a more sustainable food system. Furthermore, with the growth of the elderly population worldwide, there is an interest in developing foods to promote the health of the elderly. Objective: This study aimed to evaluate the impact of partial replacement (50%) of dairy proteins by al...
Development and bioactive potential of films from plant residue enriched with e...
Melo, A.; Lopes, A. I.; Barros, L.; Tavaria, F.; Pintado, M.Introduction: Traditional plastic food packaging is typically non-renewable and non- biodegradable, creating a need for new eco-friendly and sustainable alternatives, such as plant- based films. Plant agro-industrial wastes have been explored as sources of polymeric matrices in film development. Additionally, natural compounds from plants, like plant extracts (PEs) and essential oils (EOs) can provide these fil...
