The objectives of this study were to provide fundamental information on how individual phenolic compounds form on the inside of apple slices during cold storage, the changes in the content of four types of phenols, ingredient variation of individual phenolic compounds and the influence of phenolic compounds on enzymatic browning. This study measured the changes in the content of soluble solids, pH and vitamin C in order to investigate the correlations between these variables. HD and FA were the main phenolic compounds found in the apple slices, and HD was the most prevalent phenol. Furthermore, comparison of the CG and EP content revealed that there were more CGs than EPs. The phenol content tended to decrease considerably in the fresh apple slices and water-dipped apple slices but only slightly in the CP from sucrose-dipped apple slices and 0.5% ascorbic acid solution-dipped apple slices. The degree of browning increased in the following order: fresh apple slices, water-dipped apple slices, 0.5% ascorbic acid solution-dipped apple slices and CP from sucrose-dipped apple slices. The vitamin C content tended to decrease in the fresh apple slices, water-dipped apple slices, 0.5% ascorbic acid solution-dipped apple slices and CP from sucrose-dipped apple slices. The pH tended to increase in all sample groups, but the pH of the water-dipped apple slices was lower than that of the comparison group. The CP from sucrose-dipped apple slices had the lowest value of pH. The change in soluble solids tended to increase in all treatment groups, but this increase was less in the CP from sucrose-dipped apple slice. Correlation analysis revealed a high degree of correlation between browning and chlorogenic acid content. The results of the present study show that, when stored in the fridge, the change in phenol ingredient content in apple slices influences the browning of the slices. The results also showed that HD and FA were the main phenolic compounds, while CG was shown to have the greatest influence on browning.
