Control of browning and decay of three cultivars of baby corn were studied in relation to their postharvest changes and quality. Baby corn cv. Chiang Mai 90 had the greater browning than cvs. CP45 and Pacific No.5. The browning appearance of baby corn did not have relationship with L value, while did with weight loss and total phenolics content. Baby corn cv. CP45 had the greatest decay after 6-day storage at ambient temperature. Sodium hypochlorite at 100, 200 and 300 ppm completely controlled decay of baby corn cv. CP45 for the first 4-day storage and had the least decay by the end of storage as compared to the control. Sodium hypochlorite treatment had no significant effect on color and total sugars of baby corn. Ascorbic acid and Eribate at 0.05, 0.1 and 0.2 percent and calcium chloride at 0.5, 1.0 and 2.0 percent were tested to control browning of baby corn cv. CP45. Only Eribate at 0.2 percent was the most effective in reducing browning of baby corn. Ascorbic acid, Eribate and calcium chloride at all concentration had no significant effect on L value, weight loss and total phenolics, but reduced polyphenol oxidase activity. The storage of baby corn cvs. CP45 and G5406 with husk at 3, 5, 7 and 9 C found that CP45 had more browning, L value and total sugars content than cv. G5406. Browning and weight loss were greater at higher temperature while total sugars content was greater at lower temperature. Baby corn cvs. CP45 and G5406 had a shelf life of 8 and 16 days at 3-7 C, respectively. Phenylalanine ammonialyase activity in baby corn was very low.
