- Multivariate analysis in accelerated shelf-life assessment - an overviewPublication . Lima, Laíres; Pereira, Ana I.; Pintado, Manuela; Carocho, Márcio; Barros, LillianTo meet the market demand for high-quality products, researchers and manufacturers have invested in the development of accurate methods for estimating shelf-life. Tests that consider the simultaneous effects of different parameters on food degradation are useful tools in shelf-life studies, as these parameters can directly influence quality and safety. With this in mind, the objective of this review is to gather pertinent information from recent studies (2006–2022) pertaining to multivariate analysis applied in accelerated shelf-life tests in order to facilitate a comprehensive understanding. The review focuses on multivariate techniques commonly employed in accelerated shelf-life modeling, namely, principal components analysis, partial least squares regression, orthogonal projections to latent structures discriminant analysis, and hierarchical cluster analysis. Through an extensive literature review, the collected data represent the evolution of these methods, taking into account current trends, advances in food shelf-life techniques, and future perspectives. It was observed that the recent literature provides limited information on the determination of shelf-life under multiple accelerated factors. However, the studies analyzed showed that multivariate analysis can be a useful tool in the interpretation of quality characteristics and can accurately predict the shelf-life of foods compared to univariate kinetic procedures. The multivariate statistical methods addressed in this work are presented as a promising method for foods tested, being applied together with different chemometric techniques. This comprehensive review contributes to the body of knowledge surrounding accelerated shelf-life testing, offering valuable insights for researchers, manufacturers, and stakeholders in the food industry.
- Portuguese Football Federation consensus statement 2020: nutrition and performance in footballPublication . Abreu, Rodrigo; Figueiredo, Pedro; Beckert, Paulo; Marques, José P.; Amorim, Samuel; Caetano, Carlos; Carvalho, Pedro; Sá, Carla; Cotovio, Ricardo; Cruz, Joana; Dias, Tiago; Fernandes, Gonçalo; Goncalves, Elton; Leão, César; Leitão, Alexandre; Lopes, João; Machado, Eduardo; Neves, Mónica; Oliveira, André; Pereira, Ana I.; Pereira, Bruno; Ribeiro, Fernando; Silva, Luís M.; Sousa, Filipe; Tinoco, Tânia; Teixeira, Vitor H.; Sousa, Mónica; Brito, JoãoNutrition is an undeniable part of promoting health and performance among football (soccer) players. Nevertheless, nutritional strategies adopted in elite football can vary significantly depending on culture, habit and practical constraints and might not always be supported by scientific evidence. Therefore, a group of 28 Portuguese experts on sports nutrition, sports science and sports medicine sought to discuss current practices in the elite football landscape and review the existing evidence on nutritional strategies to be applied when supporting football players. Starting from understanding football's physical and physiological demands, five different moments were identified: preparing to play, match-day, recovery after matches, between matches and during injury or rehabilitation periods. When applicable, specificities of nutritional support to young athletes and female players were also addressed. The result is a set of practical recommendations that gathered consensus among involved experts, highlighting carbohydrates periodisation, hydration and conscious use of dietary supplements.
