Food Nutrition Current Topics of Investigation

Evaluating lycopene-rich tomato products' ability to modify postprandial oxidative stress, inflammation and endothelial function in healthy weight individuals and the potentially important protective role of tomato in reducing cardiovascular disease risk.

  • Developing methods for assessing antioxidant capacity of fruit and fruit-based beverages, and investigating phenolic compound composition and antioxidant capacities of strawberry- and milk-containing beverages.
  • Determining the impact of HPP and HT (pasteurization) on the antioxidant capacity of strawberry/milk-based beverages as measured by ORAC and FRAP units.
  • Investigating the stability of abundant flavonoids in processed versus unprocessed beverage samples using the LC-MS/MS technique, and assessing the effect of processing on microorganisms and their growth over a target storage period.
  • Detecting, identifying and quantifying polyphenolic compounds and their metabolites in human plasma after ingestion of a strawberry-based beverage using LC-MS/MS in order to examine the availability of phytochemicals and the correlation between the concentrations of such compounds in human blood and their consequent health-promoting bioactivity.
  • Establishing rapid in vitro assays to assess the effects of fruit polyphenols on endothelial cell functions.
  • Identifying and characterizing health-promoting compounds in cranberries to enhance understanding of the phenolic composition, antioxidant properties, biological activities, and other potential health benefits of red and white cranberry fruits.
