Analysis of olive oil coloration using ultraviolet-visible (UV-Vis) spectroscopy is an efficient technique for detecting adulterations, offering advantages over traditional methods like gas chromatography (CG) and high-performance liquid (HPLC) in terms cost, time, expertise. The development a method that integrates fatty acid composition spectral properties into portable analytical technique, such as smartphone-based digital image analysis, can enhance cost-effectiveness environmental...
Abstract: The objective of this work was to evaluate multivariate calibration models predict total lipids, crude protein, and moisture content in grinded soybean grains using near-infrared spectroscopy partial least squares (PLS). Three hundred samples soybean, evaluated duplicate, were used for reference spectral measurements. PLS validated by figures merit accuracy precision, respectively, 0.75 0.67 0.51 0.46 0.97 0.99 moisture. developed can be as an alternative methodology the...
Almond-based beverages are valued for their functionalities. However, cases of adulteration found in the literature aiming to reduce costs. In this study, almond (LA) and peanut (LP)-based were used as investigational controls commercial products analyzed by gas chromatography direct infusion electrospray ionization mass spectrometry (ESI-MS) combined with principal component analysis (PCA). Thus, characteristic fatty acids identified plant-based beverages. The ESI-MS method PCA indicated...
This study successfully applied a potentiometric E-tongue with 20 cross-selectivity lipidic polymeric membranes in the discrimination of three semi-quantitative groups, that represented following intervals honey adulteration percentage cane sugar: 0 %; [0, 10]%; [10, 20]% adulteration. We analysed five different types Portuguese honey; brands sugar were added to adulterated samples; comparative analysis was then performed. Linear discriminant coupled tabu search algorithm for feature...
This study evaluates the fatty acid composition and lipid nutritional quality of enteral diets (ED), focusing on patients requiring nutrition (EN). EN is crucial for unable to take adequate oral nutrition. The emphasis importance unsaturated acids, particularly those from omega-6 (n-6) omega-3 (n-3) series, present in diets. These acids are associated with health benefits, such as preventing cardiovascular disease modulating immune system. Seven adult ED three pediatric were analyzed, using...
Muito tem-se falado sobre a importância do leite humano (LH) ao desenvolvimento infantil. Mas, há situações em que o bebê é impossibilitado de amamentar, então, LH doado banco torna-se sua melhor opção. Para garantia da ausência microbiota patogênica passa por processamentos, qual pasteurização Holder técnica escolha na maioria mundo. Contudo, neste tipo tratamento impactos negativos aos componentes nutricionais estão sendo apontados, tornando-se necessário técnicas alternativas para sejam...

As abelhas Apis mellifera coletam um conjunto de substâncias da natureza para assegurarem a sua sobrevivência, nomeadamente o néctar, que é principal fonte em carboidratos e utilizado produção energia, pólen onde retiram as proteínas, minerais, vitaminas lipídeos água atua no controle temperatura umidade colmeia. O consumo ocorre todas fases do desenvolvimento das abelhas, porém na fase adulta dieta quase exclusiva à base destas substâncias, necessitando uma abelha aproximadamente 4 mg...
This work aims to propose an alternative methodology measure acidity index and chlorophyll content in ground soybean grains using ultra-compact near-infrared (NIR) spectrometer. Experiment was conducted 592 samples for 348 content, harvested southern Brazil. A partial least squares (PLS) model developed both parameters, being optimized by outlier detection validated through its merit figures. For the acid root mean squared error calibration (RMSEC) 0.1974 validation (RMSEP) 0.1694,...
