Abstract
Changes in the contents of four carotenoids during maturation of three varieties of Vitis vinifera were studied and the compounds localized in the main parts of the mature berry. Carotenoid levels decreased progressively from the onset of fruit development to the end of maturation, with a sharp decrease during veraison. The possible cause of this trend is discussed. In mature berries, carotenoid levels were higher in skin than in pulp. No carotenoids were detected in juice.
