Combined techniques of storage to prevent superficial scald in "Stark Delicious" apples.

Combinations of various treatments (ethyl alcohol saturation, heat treatment, ultra-low oxygen (ULO) storage and ethylene removal) were assessed for their effects on scald control and internal breakdown of Stark Delicious apples after storage for 210 days followed by 7 days of shelf life at 20 deg C. Heat treatment (38 deg for 48 h, 90% RH) followed by ULO storage (1.2% O2, 0.8% CO2) gave the best results (0.87% scald and 0% internal breakdown, compared with 75.85% scald and 35% internal breakdown in fruits stored in air). A combination of one week in an atmosphere with ethyl alcohol, prior to ULO storage, and catalytic ethylene removal also gave good results. The effects of the treatments on internal ethylene, ethyl alcohol, acetaldehyde, alpha -farnesene and conjugated trienes are described.
