Contributions of Nonvolatile Phytochemicals to Nutrition and Flavor

ADDITIONAL INDEX WORDS. ascorbic acid, dietary fiber, folate, organoleptic, phytoestrogens, polyphenolics SUMMARY. Small fruit are rich in several types of phytochemicals, vitamins, and minerals. These compounds have health functional properties that may protect humans from cardiovascular disease and certain cancers. Several of these phytochemicals, such as dietary fiber, anthocya- nins, and polyphenolics, also contribute to small fruit quality. Other components contribute to appearance and taste. Nonvolatile organic acids contribute to the perceived sourness of small fruit and changes in levels can alter visual color by affecting cellular pH and anthocyanin structure. The soluble sugars glucose, fructose, and sucrose contribute directly to the perceived sweetness of the fruit and provide carbohydrates for other metabolic functions such as phe- nolic and ascorbic acid synthesis.
