Biological Properties Evaluation And Chemical Profiles Of Phenolic Compounds In Muscadine Grapes (Vitis Rotundifolia), Qi You May 2012

Biological Properties Evaluation And Chemical Profiles Of Phenolic Compounds In Muscadine Grapes (Vitis Rotundifolia), Qi You

All Dissertations

Phenolic compounds, including anthocyanins in muscadines have attracted much attention due to their diverse biological activities. With bioassays of antioxidant activities in terms of total phenolic content (TPC), total flavonoid content (TFC) total anthocyanin content (TAC), total procyanidin content (TPA), oxygen radical absorbance capacity (ORAC), ABTS radical scavenging Activity (ABTS), ferric reducing antioxidant power (FRAP), and oil peroxidation inhibitory capacity of all muscadine samples, the muscadine grapes showed strong antioxidant activities. The liquid-liquid organic solvent extraction successfully separated the anthocyanins and other phenolics to different fractions. Strong linear relationship between responses of TPC, TAC and TPA versus their antioxidant activities ...

Migration of compounds from packaging materials is one of the most important aspects of food safety. The main purpose of this study is determination and quantification of migrated BADGE and its derivatives in canned tuna fishes by a rapid HPLC (High Performance Liquid Chromatography) method with fluorescence detector. Samples have been collected from Iran’s market by PMS method (Post Marketing Service) from different regions of Iran. Migrated compounds were extracted with methanol then analyzed by a HPLC system. This method can detect the amount of BADGE and its derivatives in low concentration. Whereas detection limit for BADGE.2H2O was ...

In the present study, York cabbage was used as the sole substrate for the lactic acid (LA) fermentation with Lactobacillus plantarum. York cabbage was blanched at 95°C for 12min to inactivate surface microflora prior to fermentation. To achieve an optimal fermentation condition which would result in higher release of phytochemicals and antioxidant (AO) capacity in the broth, Box-Behnken design integrating a desirability approach was used. A second-order polynomial equation was developed indicating the effect of solute/liquid ratio, agitation rate and fermentation time on desired parameters. The optimized factors were used for fermenting York cabbage to obtain maximum bacterial ...
