Ultrasound-assisted micellar extraction of phenolic antioxidants from spices and antioxidant properties of the extracts based on coulometric titration data
Ultrasound-assisted micellar extraction of phenolic antioxidants from spices has been developed for the first time. The effect of the surfactant nature and its concentration on the extraction efficiency has been evaluated. Electrogenerated hexacyanoferrate(III) ions have been used as coulometric titrants owing to their selectivity towards phenolic antioxidants. The best recovery of phenolic ant...
متن کاملEffect of Plant Antioxidant and Antimicrobial Compounds on the Shelf-life of Seafood – A Review
Pezeshk S., Ojagh S.M., Alishahi A. (2015): Effect of plant antioxidant and antimicrobial compounds on the shelf-life of seafood – a review. Czech J. Food Sci., 33: 195–203. While the use of synthetic antioxidants and antibacterials to keep the quality of seafood products has become a commonplace, consumer concern about their safety has motivated the seafood industry to seek natural alternative...
متن کاملInhibition of nuclear factor kappaB by phenolic antioxidants: interplay between antioxidant signaling and inflammatory cytokine expression.
Phenolic antioxidants inhibit the induction of inflammatory cytokines by inflammatory stimuli. Here, we analyzed the mechanism by which the antioxidants inhibit LPS-induced expression of tumor necrosis factor alpha (TNFalpha) in macrophages. Hydroquinone and tert-butyl hydroquinone, prototypes of phenolic antioxidants, block lipopolysaccharide (LPS)-induced transcription of TNFalpha and a nucle...
متن کاملProperties of Bread Dough with Added Fiber Polysaccharides and Phenolic Antioxidants: A Review
During breadmaking, different ingredients are used to ensure the development of a continuous protein network that is essential for bread quality. Interests in incorporating bioactive ingredients such as dietary fiber (DF) and phenolic antioxidants into popular foods such as bread have grown rapidly, due to the increased consumer health awareness. The added bioactive ingredients may or may not p...
متن کاملQuantitative Structure-Pproperty Relationship Modeling of the Redox Potential for Some Phenolic Antioxidants
In this work, quantitative structure-property relationship (QSPR) approaches were used to predict the redox potential of 42 phenolic antioxidants. The structures of all compounds optimized by the AM1 semi-empirical method and then a large number of molecular descriptors were calculated for each compound in the data set. Subsequently, stepwise multilinear regression was applied to select the mos...
متن کاملA review of phenolic antioxidants isolated from endophytic fungi
Oxidative stress caused by overproduction of free radicals or oxygenated radical species plays a major role in causing many diseases. The findings suggest the use of antioxidants as compounds to control the release of these radicals or directly prevent their formation. Therefore, antioxidants can be used as drugs to reduce or prevent oxidative stress. Herbal medicines are the basis of modern ph...
