Behind the scenes of anthocyanins—From the health benefits to potential applica...
Câmara, José S.; Monica Locatelli; Pereira, Jorge A. M.; Oliveira, Hélder; Arlorio, Marco; Fernandes, Iva; Perestrelo, Rosa; Freitas, Victor<jats:p>Anthocyanins are widespread and biologically active water-soluble phenolic pigments responsible for a wide range of vivid colours, from red (acidic conditions) to purplish blue (basic conditions), present in fruits, vegetables, and coloured grains. The pigments’ stability and colours are influenced mainly by pH but also by structure, temperature, and light. The colour-stabilizing mechanisms of plants ar...
Authentication of carnaroli rice by HRM analysis targeting nucleotide polymorph...
Grazina, Liliana; Costa, Joana; Amaral, Joana S.; Garino, Cristiano; Arlorio, Marco; Mafra, IsabelCarnaroli is a high quality and priced variety, being considered as one of the finest Italian rice varieties due to its sensorial and rheological properties and, thus being a potential adulteration target. The present work aimed at exploiting polymorphisms in the Alk (A/G and GC/TT in exon 8) and Waxy ((CT)n and G/T in intron 1) genes by HRM analysis to differentiate Carnaroli rice from closely related varietie...
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...
Global volatile signature and polyphenols patterns in Vespolina wines according...
Bordiga, Matteo; Perestrelo, Rosa; Câmara, José S.; Yang, Qiong‐Qiong; Corke, Harold; Travaglia, Fabiano; Locatelli, Monica; Arlorio, MarcoThe global volatile signature of Vespolina wines from different vintages was established using solid-phase microextraction combined with gas chromatography–mass spectrometry (HS-SPME/GC-qMS). Wines were also characterised in terms of bioactive compounds (such as individual polyphenols, biogenic amines and their precursors) by high-performance liquid chromatography (RP-HPLC). In addition, some physic ochemical p...
Applicability of HRM analysis for carnaroli rice authentication based on polymo...
Grazina, Liliana; Costa, Joana; Amaral, Joana S.; Garino, Cristiano; Arlorio, Marco; Oliveira, Beatriz; Mafra, IsabelRice (Oryza sativa L.) is a staple food and one of the most important cereals in the worldwide. Italy, the leading rice producer in Europe, holds nearly 200 different varieties in the available germplosm [1]. The Carnaroli rice is a high quality and priced variety belonging to the group of ja ponica ecotype, produced mainly in Piedmont. it is considered one of the finest Italian rice varieties due to its excell...
Exploiting polymorphisms in the Waxy and Alk genes of Italian rice varieties to...
Grazina, Liliana; Costa, Joana; Amaral, Joana S.; Garino, Cristiano; Arlorio, Marco; Oliveira, Beatriz; Mafra, IsabelRice (Oryzasativa L) is one of the most important cereals in the world, being Italy its main producer in Europe with nearly 200 different varieties present in the germplasm [1] Italian rice varieties have different characteristics, from which the starch composition is a highly relevant parameter.
