1. Consumer awareness of food antioxidants. Synthetic vs. Natural
Abstract Food antioxidants are a core topic of food science due mainly to the consumption of ultra-processed foods, which cannot be overlooked, and represent an importance to modern society. At the same time, natural food antioxidants are gaining attention in studies due to its food safety aspects, that commonly affect food choices. Based on this, the presen

5. Stabilization effect of kraft lignin into PBAT:Thermal analyses approach
ABSTRACT Sterically hindered phenols are an important class of synthetic antioxidants for polymers, commonly incorporated to inhibit polyolefins or polyesters oxidation. However, synthetic antioxidants use is under restricted regulation due to their potential health risk and environmental impacts. Thus, great interest has been attracted to the phenol-based n

7. Determination of the Antioxidant Capacity of Red Fruits by Miniaturized Spectrophotometry Assays
Natural sources with high antioxidant capacity represent an interesting potential to prevent or minimize the oxidative stress that causes many chronic diseases. The antioxidant capacity of red fruits (strawberry and cherry) was evaluated by miniaturized spectrophotometric methods 2,2’-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS), 2,2-diphenyl-1-

9. Polysaccharides of red alga Gracilaria intermedia: structure, antioxidant activity and rheological behavior
Abstract A sulfated polysaccharide fraction from the red alga Gracilaria intermedia (PLS) was obtained by papain digestion (60 °C, 30 min). The extract was subjected to colorimetry and turbidimetry analysis, Fourier transform infrared (FTIR) spectroscopy, 1H, 13 C and 2D 1H COSY nuclear magnetic resonance (NMR) and gas chromatography/mass spectrometry anal

10. Oxidative stability of soybean oil added to coffee husk extract (Coffea arabica L.) under accelerated storage conditions
Abstract Several plants have been studied as potential sources of natural antioxidants for use in the food industry, especially polyphenols. The aim of this study was to evaluate the effects of hydroalcoholic extract from coffee husk on the oxidative stability of soybean oil when stored in an oven. Samples were maintained at a temperature of 60 °C and their

12. Effects of low-protein diets supplemented with antioxidants on histopathology of testis and testosterone and performance of male Japanese quail ( Coturnix coturnix japonica )
ABSTRACT The present study sought to examine the effects of low-protein diets supplemented with natural and synthetic antioxidants on reproductive traits and performance of male Japanese quail. A total of 144 one-day-old quail chicks were randomly assigned to receive four different treatments, including a control diet (a basal diet) without antioxidant suppl
