It has been suggested that ethylene production can be re- duced by half at an oxygen level of ∼2.5% (Sandhya, 2010). The benefits of MAP and cold storage have been found in reducing ethylene production and activation (Beaudry, 1999), but MAP alone is not adequate to control ethylene production. For very sensitive fruit commodities such as kiwifruit, packaging with sufficient ethylene-absorbing ca- pability may be essential in maintaining quality and shelf life for commercial purposes (Zagory, 1995). This point has led to extensive research studies over the past two decades regarding the removal of ethylene from package headspaces and/or in suppressing its effects. One relatively recent dis- covery of 1-methyl cyclopropane (1-MCP) as an inhibitor of ethylene action has received considerable attention for improving the shelf life of climacteric fruits, but this subject will not be covered in this chapter.
