Abstract

A component with electrophoretic mobility identical to authentic gum exudate and to stone gum was present in extracts of plum fruits containing pockets of stone gum, but absent from extracts of fruits lacking visible evidence of gum. The pectin content was greater in fruits showing a higher incidence of gumming. It is concluded that gum is absent from normal fruits, and its production in quantity is associated with an increased pectin content.
