Unripe grapes (UGs) are a waste product of grapevine cultivation and an emerging source of several compounds, such as organic acids, phenols, vitamins and mineral salts, of great economic importance to the pharmaceutical, cosmetic and food industries. Traditionally, products made from UGs, such as verjuice and sour grape sauces, have been used as seasoning or acidifying agents. The health effects of grape compounds are described as anti-inflammatory, cardio-protective, anti-cancer and anti-diabetic, as often demonstrated by both in vitro and in vivo studies. Recently, UGs have received renewed attention due to the innovative potential applications of their extracts in food and beverages for purposes of preservation and enrichment with healthy compounds, or for direct use in the human diet. The aim of this paper is to review the composition and properties of unripe grape products (UGPs) and their traditional and innovative application in food and beverages.

Abstract
Unripe grapes (UGs) are a waste product of grapevine cultivation and an emerging source of several compounds, such as organic acids, phenols, vitamins and mineral salts, of great economic importance to the pharmaceutical, cosmetic and food industries. Traditionally, products made from UGs, such as verjuice and sour grape sauces, have been used as seasoning or acidifying agents. The health effects of grape compounds are described as anti-inflammatory, cardio-protective, anti-cancer and anti-diabetic, as often demonstrated by both in vitro and in vivo studies. Recently, UGs have received renewed attention due to the innovative potential applications of their extracts in food and beverages for purposes of preservation and enrichment with healthy compounds, or for direct use in the human diet. The aim of this paper is to review the composition and properties of unripe grape products (UGPs) and their traditional and innovative application in food and beverages.File | Dimensione | Formato | |
