Abstract
Abstract This study was conducted to evaluate the effect of high CO 2 pre-storage treatment on the quality of tomatoes ( Lycopersicon esculentum Mill.) during ripening. Tomatoes at different maturity stage of breaker and pink were treated in air, or CO 2 (25, 50, 100%) for 24 hr at 20 ℃ before ripening in air at 20 ℃ . Change of surface colour and softening were reduced by high CO 2 treatment of all concentrations. This effect of CO 2 on the colour and softening was higher in breaker fruit than pink fruit. CO 2 concentration of 25 ～ 100% did not affect on soluble solids content during ripening period. Titratable acidity of breaker tomatoes were reduced by 100% CO 2 treatment. High CO 2 treatment slightly reduced sweetness of breaker tomatoes. Acidity and texture of tomatoes increased with high CO 2 treatment. Off-flavour was denoted by CO 2 treatment in pink tomatoes. The external CO 2 injury developed after 22 days at 20 ℃ in pink tomatoes when treated with ≥ 25% CO 2 and in breaker tomatoes with
