Pectic acid, also called polygalacturonic acid, is a clear, water-insoluble gelatinous acid that can be found in various vegetables and overripe fruit. It is created when pectinase and pectin interact, a process that results from the breakdown of pectin in plants (the latter being widespread in the wine-making sector.) The pectic material found in fruits during their early growth is a water-insoluble protopectin, which is transformed into pectin by the fruit ripening enzyme protopectinase. Becau...
