Storage Techniques

Storage Techniques

Non-chemical scald control is a major focus of storage technologies. A positive result is the 10-month control of superficial scald using repeated low oxygen stress (RLOS). Storage technologies for Abate Fetel are still a work in progress, and further refinements are still required. A new project focusses on the extended storage of Cripps’ Pink in conjunction with SmartFreshSM treatment.
