Laboratory tests were conducted to determine the effects on lettuce of TECTROL, a proprietary system for shipping fresh vegetables and fruits in specially proportioned atmospheres in refrigerated containers and rail cars. Storage periods approximating the extended overseas shipping and distribution time frames of four to eight weeks required by the military were used. The tests showed that where controlled atmospheres were maintained, significant improvements in quality and storage life were obtained. Reductions in slime, pink rib and russet spotting were found. Increased storage life in air remained after removal from controlled atmosphere when compared with the quality of lettuce which had been stored in air by the conventional method.
