Pieces (18×35 mm cylinders) were prepared from sanitized fruits of four honeydew melon varieties (Green Flesh, Morning Ice, Rico, RML 2704) harvested at typical commercial maturity. Pieces were stored in air or controlled atmosphere (CA=air+15% CO2) at 5°C and evaluated for sensory quality, firmness, color and soluble solids concentration (SSC) after 0, 6 and 12 days. Significant variation was found among varieties in SSC (9.9¯12.2%), firmness (14.0¯19.9 N), and chroma (10.4¯19.0), hue angle (115¯113) and L* (63.7¯66.8) color values of pieces on day 0. Pieces from the four varieties averaged 10 N firmness loss from day 0 to 12 and CA reduced loss significantly in only one variety. During air storage color saturation decreased only in pieces from varieties with high initial chroma (C) values. Average C between days 0 and 12 was -3.7 for air-stored vs -1.0 for CA-stored pieces. Average L* was -5.8 and -1.4 for the same conditions, respectively. SSC were maintained during storage in air or CA. Pieces stored in 15% CO2 had higher visual quality scores than those stored in air. In addition, CA storage greatly reduced development of macroscopic decay, translucency and off-odors.
