STORAGE OF BUTTER-TYPE HEAD LETTUCE IN CONTROLLED ATMOSPHERES
The results indicated that the effect of treatments of 2 to 4 % CO2 and 2 % O2 was similar to that of storage in air. A simulated sale proved that storing in controlled atmospheres was slightly superior to storing in air. But head lettuce has to be consumed not later than two days after taking the produce from the store. No remarkable advantage could be achieved by normal CA storage (without converter) of head lettuce.
