Interpretive Summary:

Technical Abstract: Plant secondary metabolites (e.g., phenolics) are important for human health, in addition to the organoleptic properties they impart to fresh and processed foods. Consumer expectations such as appearance, taste, or texture influence their purchasing decisions. Thorough identification of phenolic compounds is key to discerning how cultivar selection, breeding strategies, environment, post-harvest conditions, and processing methods ultimately affect food quality. Highlights on the elucidation and quantification of phenolics in grapes, berries, culinary and medicinal herbs, along with dietary supplements will be presented; data can improve production and processing. Discussion will include how (1) canopy, cover crop, and nutrient management alter metabolites in wine grapes; (2) winemaking conditions influence wine structure; (3) characterizing cultivar variability in polyphenolics aiding enhanced germplasm selection in berries; (4) processing methods alter efficiency of phenolic extraction in final products; and (5) utilizing phenolic profiles to detect adulteration. Invited presentation for ACS AGFD Young Scientist award symposium competition.
