Emotional competencies and physical activity in primary school children: A comp...
Antunes, Filipa; Antunes, Hélio; Rodrigues, Ana; Sabino, Bebiana; Ashraf, Sadaf; Sousa, Duarte; Carvalho, JoanaChildren's emotional development is a determining factor for their school success and overall well-being. Additionally, physical activity is recognized as a relevant contribution in promoting emotional self-regulation, self-esteem, and social inclusion. This aspect is especially important in the inclusive educational context, where it seeks to respond to the needs of students with learning difficulties through ...
High value-added lignin extracts from sugarcane by-products
Mota, Inês F.; Burgal, João da Silva; Antunes, Filipa; Pintado, Manuela E.; Costa, Patrícia S.This study evaluates the production of lignin bioactive extracts from sugarcane bagasse (SCB) and straw (SCS) alkaline black liquors using greener precipitating agents (methane sulfonic acid (MSA), formic acid (FA) and lactic acid (LA)) as replacers of sulfuric acid (SA), the most common one used in industry. Results showed that the highest precipitation yield was achieved by LA when applied to SCB (14.5 g extr...
Lignin from sugarcane bagasse as a prebiotic additive for poultry feed
Fangueiro, Joana F.; Carvalho, Nelson Mota de; Antunes, Filipa; Mota, Inês F.; Pintado, Manuela Estevez; Madureira, Ana Raquel; Costa, Patrícia SantosDiet is a crucial factor on health and well-being of livestock animals. Nutritional strengthening with diet formulations is essential to the livestock industry and animal perfor-mance. Searching for valuable feed additives among by-products may promote not only circular economy, but also functional diets. Lignin from sugarcane bagasse was proposed as a potential prebiotic additive for chickens and incorporated ...
From sugarcane to skin: lignin as a multifunctional ingredient for cosmetic app...
Antunes, Filipa; Mota, Inês F.; Fangueiro, Joana F.; Lopes, Graciliana; Pintado, Manuela; Costa, Patrícia SantosLignin has been suggested as a promising candidate for cosmetic applications due to its remarkable potential to absorb ultraviolet rays and distinctive antioxidant activity. This study aims at evaluating the performance of lignin from sugarcane bagasse (SCB) as natural UV blocker, antioxidant, and pigment. Lignin was extracted from SCB, characterized and incorporated into a blemish balm (BB) cream. The biologic...
Sugarcane light-colored lignin: a renewable resource for sustainable beauty
Mota, Inês F.; Antunes, Filipa; Fangueiro, Joana F.; Costa, Carina A. E.; Rodrigues, Alírio E.; Pintado, Manuela E.; Costa, Patrícia S.Lignin has emerged as a promising eco-friendly multifunctional ingredient for cosmetic applications, due to its ability to protect against ultraviolet radiation and its antioxidant and antimicrobial properties. However, its typical dark color and low water solubility limit its application in cosmetics. This study presents a simple process for obtaining light-colored lignin (LCLig) from sugarcane bagasse (SCB) a...
A review on the valorization of lignin from sugarcane by-products: from extract...
Antunes, Filipa; Mota, Inês F.; Burgal, João da Silva; Pintado, Manuela; Costa, Patrícia SantosThe sugarcane industry generates several by-products including the harvest residue (straw) and the fibrous fraction following juice extraction (bagasse). The conversion of sugarcane industry by-products into value-added products is of paramount importance from a sustainable circular economy perspective. Also, the increase of second-generation bioethanol production has triggered the development of approaches to ...
Valorization of lignin from sugarcane by-products: review
Antunes, Filipa; Mota, Inês F.; Burgal, João da Silva; Pintado, Manuela Esteves; Costa, Patrícia SantosThe valorization of sugarcane industry by-products is fundamental to increase competitiveness on a circular economy point of view. Straw and bagasse are by-products with huge potential as source of added value ingredients. Lignin is an abundant component found in these by-products with proved biological activity, particularly antimicrobial, antioxidant and UV protection. Additionally, recent applications on mat...
Sugarcane bagasse as source of bioactive lignin: influence of pretreatment on t...
Antunes, Filipa; Mota, Inês F.; Burgal, João da Silva; Pintado, Manuela; Costa, Patrícia SantosSugarcane industry generates several by-products of particular interest in the context of a circular economy, due to their potential as a source of value-added ingredients. Bagasse is one of the main by-products, consisting of a fibrous fraction obtained after juice extraction. Sugarcane bagasse is composed of cellulose, hemicellulose, and lignin, with lower amounts of extractives and ash (del Río et al., 2015)...
Impact of postharvest preservation methods on nutritional value and bioactive p...
Marçal, Sara; Sousa, Ana Sofia; Taofiq, Oludemi; Antunes, Filipa; Morais, Alcina M.M.B.; Freitas, Ana Cristina; Barros, Lillian; Ferreira, Isabel C.F.R.Background: Mushrooms are a good source of protein, dietary fibre, vitamins, minerals and phenolic compounds. However, mushrooms are a very perishable food and the implementation of preservation methods is essential to extend their shelf-life. The preservation methods for mushrooms can be classified into three categories: thermal (drying/freezing), chemical (edible coatings, films and washing solutions) and phy...
Valorization of mushroom by-products as a source of value-added compounds and p...
Antunes, Filipa; Marçal, Sara; Oludemi, Taofiq; Morais, Alcina M. M. B.; Freitas, Ana Cristina; Ferreira, Isabel C. F. R.; Pintado, ManuelaNowadays, the food sector is highly concerned with environmental issues and foreseen to develop strategies to reduce waste and losses resulting from activities developed in the food system. An approach is to increment added value to the agro-industrial wastes, which might provide economic growth and environmental protection, contributing to a circular economy. Mushroom by-products represent a disposal problem, ...
