Muscadine Grape: Postharvest Physiology and Handling Practices

Muscadines (Muscadinia rotundifolia Michx) are vining fruit crops native to the southeastern United States. Unlike the more common European Vitis vinifera (common grapes) and American Vitis labrusca grape species that produce berries in bunches, muscadine grapes are borne in clusters of individual, large berries. In addition to their sweetness and unique flavor, muscadines are appreciated for their high concentrations of bioactive compounds, which contribute to antioxidant activity and offer various health benefits to humans. The unique characteristics of muscadines make them valuable for both fresh consumption and processing purposes, including juice, wine, jam, and freeze-dried snacks. Proper postharvest handling ensures that muscadines maintain their nutritional value and appeal to consumers.
