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. Impact of whey protein isolate coatings containing different antimicrobial agents on sliced bologna-type sausage during refrigerated storage
Abstract In this study, we aimed to determine the possibility of using the edible whey protein isolates coatings containing different antimicrobial agents on the bologna-type sausage slices and the inactivation effects of these coatings against Listeria innocua. For this purpose, edible whey protein isolates (WPI) coatings were prepared to contain essential

3. 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

5. Utilization of zein-based coatings containing vegetable oils on the physicochemical characteristics of vacuum-packaged lamb meat
RESUMO: Durante a vida de prateleira da carne fresca podem ocorrer mudanças físico-químicas, microbiológicas e sensoriais indesejadas. Para evitar tais mudanças a combinação da embalagem tradicional à vácuo com revestimentos comestíveis é uma alternativa. O objetivo deste estudo foi avaliar o efeito do uso de diferentes revestimentos comestíveis

6. Evaluation of mortar properties obtained through partial substitution of Portland cement by ashes of oil palm empty fruit bunch
Resumo Atualmente, o óleo de palma é líder em produção e consumo dentre os óleos comestíveis comercializados, com uma produção mundial que ultrapassa 66 milhões de toneladas anuais. Estima-se que a produção de resíduo da queima do engaço do dendê como combustível nas caldeiras corresponde a 5% em massa do total de óleo extraído. Este trabal

7. Bioactive compounds and the antioxidant capacities of seed oils from pomegranate (Punica granatum L.) and bitter gourd (Momordica charantia L.)
Abstract Pomegranate and bitter gourd are two of the few edible fruits that contain conjugated α-linolenic acids (CLnAs) in their seeds. The CLnAs have been associated with many effects that are beneficial to health, such as antioxidant and anti-inflammatory properties. Samples of cold-pressed oils from pomegranate and bitter gourd seeds were evaluated for

8. Effect of vegetable oils applied over acquired enamel pellicle on initial erosion
Abstract Objective The prevalence of dental erosion has been recently increasing, requiring new preventive and therapeutic approaches. Vegetable oils have been studied in preventive dentistry because they come from a natural, edible, low-cost, and worldwide accessible source. This study aimed to evaluate the protective effect of different vegetable oils, a

9. Lipase-catalyzed ethanolysis of Jatropha curcas L. oil assisted by ultrasonication
ABSTRACT Transesterification of non-edible oils using immobilized lipase is a promising process for biodiesel production. Thus, this study aimed to evaluate the enzymatic transesterification of the non-edible Jatropha curcas oil for FAEE production under ultrasound irradiation in a solvent-free system. The effects of enzyme concentration, water concentration

10. Chemical composition and nutritive value of hot pepper seed (Capsicum annuum) grown in Northeast Region of China
Chemical composition and nutritive value of hot pepper seeds (Capsicum annuum) grown in Northeast Region of China were investigated. The proximate analysis showed that moisture, ash, crude fat, crude protein and total dietary fiber contents were 4.48, 4.94, 23.65, 21.29 and 38.76 g/100 g, respectively. The main amino acids were glutamic acid and aspartic aci

11. Utilization of immobilized lipases as catalysts in the transesterification of non-edible vegetable oils with ethanol
This work reports the use of commercially available immobilized lipase preparations (Novozym® 435 and Lipozyme TL IM, both from Novozymes, and Lipase PS IM from Amano) as catalysts in the transesterification reaction of different alkyl-chain triglycerides with ethanol. The ethanolysis of native oils from Brazilian Amazon plants andiroba (Carapa guianensis),

12. Essential oils of thyme and Rosemary in the control of Listeria monocytogenes in raw beef
This study was developed in order to evaluate two alternatives for the control of Listeria monocytogenes in raw bovine meat pieces, both based on the use of Thymus vulgaris and Rosmarinus officinalis essential oils (EOs). The antilisterial activity of different concentrations of the EOs was tested in vitro using agar dilution and disk volatilization techniqu
