Caratteristiche qualitative dei semi delle varietà ad uva da vino Siciliane

Abstract

In this study, the phenolic compounds of Sicilian grape seeds were evaluated. Flavan-3-ols content was higher in white and relic than black grape seeds. The greater polyphenol quantity found in white cultivars could be also attributed to lower maturity at harvest. The flavan-3-ols content was linked with seed color. The black cultivar showed the highest degree of seed lignification
