Phytochemical screening and antioxidant activity on berry, skin, pulp and seed from seven red Mediterranean grapevine varieties (Vitis vinifera L.) treated with kaolin foliar sunscreen

摘要

In the latest decades, global warming impacts become an emergent issue, and short-term techniques such as kaolin have been proposed to mitigate summer stress effects on Mediterranean viticulture. Nevertheless, the impact of this technology on grape berry composition, particularly on different fractions of whole berry (skin, pulp, and seed) is not yet studied, being these data crucial to the expansion of waste and by-product industry.
