1. Identifying olive oil fraud and adulteration using machine learning algorithms
As olive oil (OO) is more expensive than other vegetable oils, it is usually adulterated by blending it with more economic edible oils such as cottonseed oil (CSO), canola oil (CO), and soybean oil (SO). This research aimed to determine the fatty acid compositions obtained as a result of blending different proportions of CSO, CO and SO with OO using a gas ch

2. EXPERIMENTO DIDÁTICO DE QUIMIOMETRIA PARA CLASSIFICAÇÃO DE ÓLEOS VEGETAIS COMESTÍVEIS POR ESPECTROSCOPIA NO INFRAVERMELHO MÉDIO COMBINADO COM ANÁLISE DISCRIMINANTE POR MÍNIMOS QUADRADOS PARCIAIS: UM TUTORIAL, PARTE V
A teaching experiment on supervised pattern recognition in chemometrics was proposed in this tutorial to introduce partial least squares discriminant analysis (PLS-DA). A new approach of the experiment published in the first tutorial of this series was revisited and employed to the classification of edible vegetable oils. The spectra of olive, canola, soybea

3. Antimicrobial resistance, diarrheagenic and avian pathogenic virulence genes in Escherichia coli from poultry feed and the ingredients
RESUMO Escherichia coli diarreiogênicas (DEC) e patogênicas para aves (APEC) são associadas a infecções intestinais e extraintestinais (ExPEC), respectivamente. O objetivo do presente trabalho foi avaliar a sensibilidade antimicrobiana, a presença de genes que codificam os fatores de virulência relacionados à DEC e APEC, e a classificação filogené

4. Scanning Electron Microscopy and Crystallinity of starches granules from cowpea, black and carioca beans in raw and cooked forms
Abstract Beans are a vital food for the population around the world because it contains a relatively high amount of protein, vitamins, fiber, and minerals, being an important vegetable source of iron, particularly when combined with ascorbic acid and cysteine. The starch content in the seed is between 45 and 60%. This paper evaluated the granular structure o

5. Non-Invasive Detection of Adulterated Olive Oil in Full Bottles Using Time-Domain NMR Relaxometry
A fast procedure using time-domain nuclear magnetic resonance (TD-NMR) to detect olive oil adulteration with polyunsaturated vegetable oils in filled bottles is proposed. The 1H transverse relaxation times (T2) of 37 commercial samples were measured using low-field nuclear magnetic resonance (LF-NMR) spectrometer and a unilateral nuclear magnetic resonance (

6. Análisis de contenido del dominio tecnológico vegetable oil combustion
The patent document is a measurement unit for scientific and technological productivity commonly used as a technological indicator. Patent studies mainly focus on frequency counts by year, country, assignee and inventor. There are scarce studies on the technical classifications and contents of the invention. The aim of this paper is to propose the use of the

7. Development and chemical and sensory characterization of pumpkin seed flour-based cereal bars
Pumpkin (Cucurbita maxima), popularly known as squash, is a widely grown vegetable in Brazil. In this study, pumpkin seed flours (PSF) with different granulometries were used: PSF 1 (medium granulometry) and PSF 2 (coarse granulometry) in the preparation of cereal bars (CB) with different combinations with brown oats. Five formulations were prepared: CB-1 (c

8. Caracterização de biomassas brasileiras para fins de aproveitamento energético / Characterization of brazilian biomasses for energy recovery
New energetic alternatives have been the subject of discussion about conservation of natural resources. Such discourses are based mainly on reducing emissions of greenhouse gases and other pollutants, caused mostly by the use of fossil fuels, major source of energy today. In view of the applicability of biomass as energy input, this paper presents an experim

9. Uso da região espectral de sobretons para determinação do teor de biodiesel e classificação de misturas diesel/biodiesel adulteradas com óleo vegetal / Using overtone regions to determine biodiesel content and classification of diesel/biodiesel blends adulterated with vegetable oils
This work evaluates the use of overtone regions (NIR) for the classification and determination of biodiesel content in diesel/biodiesel blends adulterated with vegetable oil. For this purpose, NIR spectra were obtained using three different optical paths: 1.0 mm (9000-4000 cm-1); 10 mm (9000-6300 cm-1) e 50 mm (7500-6300 cm-1). Principal Component Analysis (

11. INOCULAÇÃO DE Fusarium moniliforme (Sheld.) EM SEMENTES DE DUAS CULTIVARES DE PEPINO ATRAVÉS DA TÉCNICA DA RESTRIÇÃO HÍDRICA E SUA INFLUENCIA SOBRE A QUALIDADE FISIOLÓGICA. / INOCULATION OF Fusarium moniliforme (Sheld.) IN SEEDS FROM TWO CUCUMBER CULTIVARS THROUGH HYDRIC RESTRAINT TECHNIQUE ON PHYSIOLOGICAL QUALITY.
The cucumber (Cucumis sativus L.) is a vegetable belonging to the family Cucurbitaceae, of great importance in Brazil. It is grown, preferentially in tropical climate, in high temperature conditions. It has a high economical, nourishing and social value because it generates direct or indirect jobs, requiring a labor demand from its cultivation to its commerc
