This study intended to evaluate the potential industrial applications of various Acacia species (Acacia melanoxylon, longifolia, cyclops, retinodes, pycnantha, mearnsii, and dealbata) by examining their chemical composition, antioxidant, antimicrobial properties. Using high-resolution mass spectrometry, a comprehensive analysis successfully identified targeted compounds, including flavonoids (flavonols/flavones) phenolic acids, such as 4-hydroxybenzoic acid, p-coumaric ellagic acid....
The traditional ageing of wine spirits is done in wooden barrels, however, high costs have led to the search for alternative technologies, such as use stainless steel tanks with staves and application micro-oxygenation. This work evaluates changes major volatile compounds aged 6, 12 18 months barrels For both two types wood (Limousin oak Portuguese chestnut wood) were used. samples analysed concerning their alcohol strength (electronic densimetry) composition, namely methanol, acetaldehyde,...
Fourier transform infrared spectroscopy (FTIR) with Attenuated Total Reflection (ATR) combined functional data analysis (FDA) was applied to differentiate aged wine spirits according the ageing technology (traditional using 250 L wooden barrels versus alternative micro-oxygenation and wood staves in 1000 stainless steel tanks), species used (chestnut oak), time (6, 12, 18 months). For this purpose, several features of were examined: chromatic characteristics resulting from CIELab method,...
Many species of the so-called exotic plants coexist with native in a balanced way, but others thrive very quickly and escape human control, becoming harmful—these are called invasive alien species. In addition to overcoming geographic barriers, these can defeat biotic abiotic maintaining stable populations. Ailanthus altissima is no exception; it disseminated worldwide considered high risk due its easy propagation resistance external environmental factors. Currently, has particular use other...
Near-infrared spectroscopic (NIR) technique was used, for the first time, to predict volatile phenols content, namely guaiacol, 4-methyl-guaiacol, eugenol, syringol, 4-methyl-syringol and 4-allyl-syringol, of aged wine spirits (AWS). This study aimed develop calibration models phenol's quantification in AWS, by NIR, faster without sample preparation. Partial least square regression (PLS-R) were developed with NIR spectra near-IR region (12,500-4000 cm-1) those obtained from GC-FID after...
Some diseases still need better therapeutic approaches, including the prevention of development. Natural resources are investigated with this purpose; among them, we decided to use an invasive plant as a main strategy. This will help in two ways: screening new compounds flowers prevents from causing widespread damage by controlling dissemination and also obtains crude material for further applications. In present study, flower extracts Acacia dealbata Link harvested Portugal were studied...
Acacia spp. is an invasive species that widespread throughout the Portuguese territory. Thus, it pertinent to better understand this in order find different applications will value its use. To evaluate phenolic profile flowers, ethanolic extracts obtained through energized guided dispersive extraction were analysed, focusing on two species, retinodes and mearnsii, at flowering stages. The phytochemical of each extract was determined by ultra-high performance liquid chromatography coupled...
The Acacia genus is considered one of the most invasive taxa in some habitats, namely coastal dunes, maritime calcareous soils, fresh lands valleys, mountainous areas, and banks watercourses roadsides. In Portugal, severity risk very high, so this study aimed to evaluate nutritional mineral contents green pods as a potential source for livestock feeds soil fertilizer because, far we know, there no use species. seven different species (Acacia mearnsii Link, longifolia (Andrews) Willd,...
"Pera Rocha do Oeste" is a pear (Pyrus communis L.) variety native from Portugal with Protected Designation of Origin (PDO). To supply the world market for almost all year, fruits are kept under controlled storage. This study aims to identify which classical physicochemical parameters (colour, total soluble solids (TSS), pH, acidity, ripening index, firmness, vitamin C, phenols, protein, lipids, fibre, ash, other compounds including carbohydrates, and energy) could be fingerprint markers PDO...
Arbutus unedo spirit is a valuable product in Mediterranean countries. This usually marketed Portugal without wood ageing. work aims to characterize the ageing effect on spirit, for three and six months with oak (Quercus robur L.) submitted different toasting levels, based its chemical composition sensory properties. For this purpose, several parameters were analysed: acidity, pH, dry extract, volatile compounds (methanol, acetaldehyde, ethyl acetate fusel alcohols). The identified by GC-MS...
Abstract Fruit juice does not have the same nutritional value as fresh fruit with regards to vitamin, mineral and dietary fibre contents antioxidant properties. However, it can be part of a healthy diet if is produced minimal addition sugar. This study aimed evaluate performance FTIR-ATR technique discriminate authenticity (concerning other pulps) amount sugar in peach nectars. usually used food analysis because require sample preparation, quick allows for determination several parameters...
In the present study, nutritive composition and mineral content of leaves eight species Acacia trees were evaluated to assess their potential for different purposes, such as food resources ruminants sources in soils. Caco-2 cells employed cytotoxicity, revealing that extracts exhibited no cytotoxic effects after cellular incubation, suggesting suitability an alternative animal feed. The proved be a promising source protein fiber, offering meet needs ruminants. differed among species, ranging...
