Muscadine grapes (Vitis rotundifolia), native to the southeastern United States, have been used as a local fruit for many years. The thick, chewy, slipskin peel and large seeds have kept muscadines as the poor cousin relative to the Vitis vinifera seedless table grape. A body of work has been done on the health aspects of muscadine to follow effects on cancer. The thick peels offer a repository of unusual flavonoids, including a range of anthocyanins. Recently, the release of seedless muscadines and of seededmuscadines with a thinner nonslip peel and crisp flesh has made these grapes attractive to a much wider range of consumers. Additionally, the anthocyanins have been shifted to increase malvidin to improve juice color stability. In this talk, the health attributes, storage life, and changes in anthocyanins of muscadine will be covered.
