This study was conducted to increase the keeping quality of the minimally processed pear slices during the cold storage. Korean pears, ‘Shin-go (Niitaka)’, ‘Chu-hwang’ and ‘Won-hwang’ were immersed in 1% ascorbic acid, 0.1% calcium propionate, 1% citric acid, 0.2% N-acetyl cysteine and 0.5 M 4-hexylresorcinol solution for 3 three minutes and then stored at 1±0.5ºC for 10 days. We have also examined into the firmness and the color difference of pears slices as affected by the application of the anti-browning agents. The firmness of pears slices which that were immersed in 0.1% calcium propionate and 0.2% N-acetyl cysteine solution were not significant at did not differ significantly after 10 days after of cold storage. However, the ?E<SUP>*</SUP> values of ‘Shin-go’ slices which that were treated with 0.1% calcium propionate and 0.2% N-acetyl cysteine solution and stored for 10 days decreased by 3.18 and 3.83, when compared with that in of the control, which decreased by 6.36. The ?E<SUP>*</SUP> values of ‘Chu-hwang’ slices which that were treated with 0.2% N-acetyl cysteine and 0.1% calcium propionate solution had the slight difference by differed by only 2.09 and 2.14, when compared with that in of the control, which differed by 3.04. The ?E<SUP>*</SUP> values of ‘Won-hwang’ slices which that were treated with 1% citric acid and 0.5 M 4-hexylresorcinol were 4.49 and 5.83, respectively, while that in of the control decreased by 8.95. It was assumed that the anti-browning agent treatment had the different activities among varieties of the pear varieties slices, however, application of 0.2% N-acetyl cysteine and 0.1% calcium propionate application had greater the higher antibrowning activity.
