                                    Citation: Lee, J. 2013. The untapped capacity of phenolics. American Chemical Society Abstracts. 246th National Meeting. AGFD 30.Interpretive Summary:
                                Technical Abstract: My research focuses on understanding the dynamics of plant primary and secondary metabolites. Though plant metabolites, including phenolics, make up only a small portion of the compounds found in a fruit or its final product, they are crucial for their contribution towards appearance (color), taste (bitterness and astringency), storability, and potential health benefits. Everyday consumers automatically and unknowingly make purchasing decisions based upon their judgment of phenolic attributes. Precise identification of phenolic compounds is key to discerning how cultivar selection, breeding strategies, environment, post-harvest conditions, and processing methods ultimately influence beverage quality. Highlights on the elucidation and quantification of phenolics in black raspberries, elderberries, wine grapes, cranberries, and the resulting products will be presented; data can improve production and processing. Presentation will also include how (1) characterizing cultivar variability in polyphenolics aids enhanced germplasm selection in berries; (2) vineyard management regimes alter metabolites in wine grapes; (3) winemaking conditions influence wine structure; (4) fruit processing methods effect efficiency of phenolic extraction in berry products.
