a fourth-generation ziegler-natta catalyst was prepared to synthesize polypropylene (pp), which was stabilized by in situ polymerization employing lignin as antioxidant. the antioxidant properties of lignin were compared with those of the commercial antioxidant irganox 1010. the presence of lignin in the reaction medium slightly decreased the catalytic activity of the reaction. the isotacticity...

Sweet potato is known to be rich in healthful antioxidants, but the stability of its antioxidant properties under gastrointestinal pH is very much unknown. Hence, this study aimed to evaluate the changes in antioxidant properties (total contents of phenolics and flavonoids as well as antioxidant activity) of sweet potato flour (SPF) under simulated gastrointestinal pH conditions. It was found t...

application of optical radiation such as laser and other short wavelength radiation for inactivation of many food-borne pathogen microorganisms in food industry (as major challenges in the food industry and so that many diseases are resulted from this food contamination) was known as a new technology. material and methods: effects of green continuous waves lasers on structural (using sds-page m...

The functionalizing of staple and economic foods, which means adding health-promoting substances, has been visualized as a solution to reduce the concerning increase in diet-related diseases caused by bad-eating patterns. Microalgae represent an innovative way solve this problem. Arthrospira platensis, microalgae nutritionally rich bioactive compounds, used develop hard wheat pasta (semolina) i...

It has been investigated the in vitro antioxidant properties of ethanol extracts of the contained-allantoin plants in this study. Contained-allantoined plant samples Plantago lanceolata, Plantago major, Robinia pseudoacacia, Platanus orientalis and Aesculus hippocastanum were tested at different concentrations. The antioxidant activities of plant samples were analysed by 1,1- diphenyl-2-picrylh...

INTRODUCTION The aims of this study were to determine the proximate composition, functional properties and antioxidant activity of pumpkin seeds and rind. Besides, the effects of dietary fibre in pumpkin seeds and rinds on bread qualities and properties were evaluated. METHODS Formulations for bread substituted with 0%, 5% and 10% pumpkin seed and rind, respectively were produced. Sensory eva...

Elucidation of Antioxidant Activity of Phosvitin Extracted from Egg Yolk using Ground Meat Samooel Jung, Cheorun Jo, Mingu Kang, Dong Uk Ahn, and Ki Chang Nam* Department of Animal Science and Technology, Sunchon National University, Suncheon 540-742, Korea Department of Animal Science and Biotechnology, Chungnam National University, Daejeon 305-764, Korea Department of Animal Science, Iowa Sta...

The schistosomicidal properties of Nigella sativa seeds were tested in vitro against Schistosoma mansoni miracidia, cercariae, and adult worms. Results indicate its strong biocidal effects against all stages of the parasite and also showed an inhibitory effect on egg-laying of adult female worms. In the present work we also studied the effects of crushed seeds on some antioxidant enzymes; which...

Quercetin (Q) was used as substrate for regioselective glycosylation at the C-7 position catalyzed by Beauveria bassiana AM278 strain. As a result the glycoside quercetin 7-O-β-d-(4″-O-methyl)glucopyranoside (Q 7-MeGlu) was formed. The goal of the studies was to determine the anti-oxidative (liposome membrane protection against free radicals IC50Q 7-MeGlu = 5.47 and IC50Q = 4.49 µM) and anti-in...
