Influence Of Dietary Phytochemicals And Microbiota On Colon Cancer Risk., Ruth S. Macdonald, Kelly Wagner May 2012

Influence Of Dietary Phytochemicals And Microbiota On Colon Cancer Risk., Ruth S. Macdonald, Kelly Wagner

Food Science and Human Nutrition Publications

Colon cancer is the third most commonly diagnosed type of cancer in the United States. Lifestyle and dietary patterns influence colon cancer risk both positively and negatively. Among the dietary factors, several plant-derived compounds have been found to afford colon cancer protection. These compounds potentially influence all aspects of colonic cellular regulation and develop complex interrelationships with the colonic microbiome. Increasing understanding of the role of microorganisms in determining the colonic environment has led to awareness of this important interrelationship among dietary factors and the microbial population. Plant-derived polyphenols are active mediators of cellular events, target key carcinogenic pathways, and ...

Polyphenols are extensively used in food, beverage, pharmaceuticals and nutraceutical industry for their positive effects on human health. Present study was designed to estimate the differences in polyphenols level and antioxidant capacity between marine and terrestrial vegetables. Considerable variations in the total phenolic content (TPC) and total flavonoid content (TFC) were observed, which ranges from 20.4 to 140.2 mg GAE/g of extracts (dw) for TPC and 15.4 to 50.4 mg QE/g of extracts (dw) for TFC. Furthermore, antioxidant capacity was confirmed by all the extracts. Results showed that marine vegetables had significantly higher polyphenols ...


Optimization Of Lactic Acid Fermentation Of York Cabbage For The Development Of Potential Probiotic Products, Amit Jaiswal, Shilpi Gupta, Nissreen Abu-Ghannam Jan 2012

Optimization Of Lactic Acid Fermentation Of York Cabbage For The Development Of Potential Probiotic Products, Amit Jaiswal, Shilpi Gupta, Nissreen Abu-Ghannam

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 ...
