1. Evaluation of the Properties of LaNiO3 Material Prepared by the Modified Proteic Method for Adsorption of Environmental Contaminants
LaNiO3 material was synthesized by modified proteic method, calcined at 900 °C/2 h in air atmosphere and was applied to remove environmental contaminants. LaNiO3 phase with a perovskite structure was formed in the calcined material, which has a surface area of 22 m2 g-1 and is formed by fine particles agglomerated, with pH of the zero charge point of 7.44.

2. Analysis of bioactive compounds in umbu (Spondias tuberosa) by application of edible coating based on Chlorella sp during storage
Abstract The use of edible coating has been an alternative to maintain the quality of vegetables and prolong their post-harvest life. This study aims to evaluate bioactive compounds in Spondias tuberosa submitted to different coating formulations based on Chlorella sp. associated with the pomegranate seed oil, to establish the one that best maintains post-ha

3. Monochromatic double coloring effect on V2O5 thin films deposited by electron beam
ABSTRACT Electrochromic material is a thin film technology that has a close relationship with environmental sustainability since they can control the light and heat that enter and leave a building. Vanadium oxide films are electrochemically active for lithium and electron co-intercalation, presenting low optical variation in the low energy visible light, whi

6. Changes in ascorbic acid and total phenolics contents associated with browning inhibition of pineapple slices
Abstract Pineapple slices were treated with three antioxidants and stored under passive modified atmosphere packaging (MAP) to evaluate the effect of these treatments on tissue browning (percentage of dark area) and the accumulation of ascorbic acid and total phenolics. Pineapple slices were immersed in ascorbic acid (AA), isoascorbic acid (IAA), and N-acety

8. Lipid oxidation in meat: mechanisms and protective factors – a review
Abstract Lipid oxidation in meats is a process whereby polyunsaturated fatty acid react with reactive oxygen species leading to a series of secondary reactions which in turn lead to degradation of lipids and development of oxidative rancidity. This process is one of the major factors responsible for the gradual reduction of sensory and nutritional quality o

9. Enhancement of the antioxidant capacity and reduction of chilling injury in ‘Douradão’ peaches refrigerated under pre-storage and modified atmosphere
ABSTRACT. The present study aimed to investigate the effects of pre-storage for 24h and 48h and different modified atmosphere packaging-MAP treatments (using low-density polyethylene - LDPE) on the antioxidant compounds and the postharvest quality of ‘Douradão’ peaches under cold storage. The peaches were submitted to the following treatments: a control

10. Effect of active antimicrobial films on the growth of pathogenic bacteria in Mantı
Abstract The current study assessed antimicrobial films for use in active food packaging. Mantı, a tortellini-like Turkish food, was packaged with antimicrobial films to extend refrigerated storage time at 4 °C. Polycaprolactone (PCL) was separately incorporated with cinnamaldehyde (CNMA) and pomegranate methanolic extract (PME) to form antimicrobial diff

11. Mixed Electrical Conduction of Calcium Aluminates Synthesized by Polymeric Precursors
A study of the electrical transport properties of calcium aluminate (CA) with coexisting C3A and C12A7 phases was carried out. In this work, powders resulting from synthesis based on the polymer precursor method. The resulting product was characterized by means of XRD, Raman, and UV-visible analysis to obtain the optical BG and by EIS. From the XRD and Raman

12. Modelling the growth of lactic acid bacteria at different temperatures
ABSTRACT Mathematical models are widely used to predict the shelf life of foods. Lactic acid bacteria (LAB), particularly Lactobacillus plantarum, Weissella viridescens and Lactobacillus sakei, are the main spoilage bacteria of refrigerated, vacuum-packed meat products, stored in modified atmosphere, and their growth determines the shelf life length of these
