Machine learning approaches applied to GC-FID fatty acid profiles to discrimina...
Grazina, Liliana; Rodrigues, Pedro João; Igrejas, Getúlio; Nunes, Maria A.; Mafra, Isabel; Arlorio, Marco; Oliveira, Beatriz; Amaral, Joana S.In the last decade, there has been an increasing demand for wild-captured fish, which attains higher prices compared to farmed species, thus being prone to mislabeling practices. In this work, fatty acid composition coupled to advanced chemometrics was used to discriminate wild from farmed salmon. The lipids extracted from salmon muscles of different production methods and origins (26 wild from Canada, 25 farme...

Grazina, Liliana; Nunes, Maria A.; Mafra, Isabel; Oliveira, Beatriz; Amaral, Joana S.Global demand for fish and fish products has increased significantly over the last decades, which led to a simultaneous increase of aquaculture production around the world, currently corresponding to almost 50% of the global fish market [1]. Among different concerns regarding the fish that consumers are eating, nowadays, there is a demand for correct information about the species, production method (farmed vs. ...
Optimization of antioxidants extraction from coffee silverskin, aroasting by-pr...
Costa, Anabela; Alves, Rita C.; Vinha, Ana F.; Barreira, Sérgio V. P.; Nunes, Maria A.; Cunha, Luís M.; Oliveira, M. Beatriz P. P.Coffee silverskin is a major roasting by-product that could be valued as a source of antioxidant compounds. The effect of the major variables (solvent polarity, temperature and extraction time) affecting the extraction yields of bioactive compounds and antioxidant activity of silverskin extracts was evaluated. The extracts composition varied significantly with the extraction conditions used. A factorial experim...
