Postharvest Effect of Modified Levels of Carbon Monoxide, Carbon Dioxide, and Oxygen on Disorders and Appearance of Head Lettuce1

Year: 1976

Type: article

Abstract: Lettuce ( Lactuca sativa L.) held in an atmosphere of 3% O2 plus 1.5% CO for 7 days at 3.3°C had a better appearance before and after the wrapper leaves were removed, than lettuce held in atmospheres with various other combinations of CO, CO2 and O2. Butt discoloration and pink rib also were inhibited by this atmosphere. These effects were no longer apparent after an additional 4-day holding period in air at 10°. Rusty brown discoloration was not affected by any of the atmospheres tested during the initial 7 days, but after 4 additional days in air, the incidence of objectionable rusty brown discoloration was higher in lettuce previously held in atmospheres with CO 2 than in those without CO 2 .
