Abstract
Compositions and processes are disclosed for treating fresh-cut apple pieces by dipping cut apple pieces in an aqueous solution containing GRAS (Generally Recognized As Safe) substances that protect the cut apple pieces from deterioration due to increased enzymatic activity, oxidative reactions, water migration and microbial effects during the extended shelf life of the fresh-cut apples pieces. The composition consists principally of L-cysteine, sorbitol and calcium chloride. A chelator such as sodium hexametaphosphate can be added to enhance the affiance of the agent. A synergistic effect is observed when apple pieces are packaged in a film that will equilibrate to oxygen and carbon dioxide levels in the range of 0.5-5.0% and 7.0-37.0%, respectively.
