Changes in apple slices during cold storage were investigated by evaluating the physical properties such as degree of browning and compression force. Chemical properties such as PPO activity and total phenol contents were also determined and sensory evaluation was carried out. The correlation analysis between browning parameters was conducted. Degree of browning was increased in the order of fresh apple slice, water-dipped apple slice, 0.5% ascorbic acid solution-dipped apple slice and CP(caramnelization product) from sucrose-dipped apple slice. PPO activity was increased in the order of fresh apple slice, water-dipped apple slice, 0.5% ascorbic acid solution-dipped apple slice and CP(caramelization product) from sucrose-dipped apple slice. Amongst several treatments, CP from sucrose-dipped apple slice showed the lowest degree of browning and PPO activity. Total phenol contents were decreased from 60 to 56.2 tug and from 59.6 to 56.0 mg in fresh apple slice and water-dipped apple slice, respectively, but CP from sucrose-dipped apple slice and 0.5% ascorbic acid solution-dipped apple slice were increased from 51.9 to 52.8 mg and from 54.1 to 54.4 mg, respectively, showing the smallest changes when compared with fresh apple slice and water-dipped apple slice. Compression forces of apple slices during cold storage were decreased in the order of fresh apple slice, water-dipped apple slice. 0.5% ascorbic acid solution-dipped apple slice and CP from sucrose-dipped apple slice. In sensory evaluation of apple slices during cold storage, CP from sucrose-dipped apple slice had higher score than the other treatments. In addition, a significant correlation was observed among degree of browning, PPO activity and phenol content. Therefore, CP from sucrose-dipped apple slice seems to be effective in controlling of enzymatic browning during cold storage. In addition, CP from sucrose-dipped apple slice seems to be effective on other several factors. These results suggest that CP from sucrose should be a potential source for controlling enzymatic browning during storage of vegetables and fruits.
