Apples are one of the most produced fruits in Korea, with 2,423,000 tons of fruits produced in Korea in 2018, of which 365,000 tons (MAF, 2018) account for about 15% of the total production. For quality safety after harvesting apples, the application of MA(modified atmosphere) packaging technology (Mostofi et. al., 2008) is being actively studied. In addition, the effects of functional packaging materials that have added functions such as fireproof, antibacterial, high-blocking, degradability, and far-infrared radiation have been studied (Chung et al., 2009). In addition, there are reports of the effects of quality changes (Park et al., 2007) and MA storage methods on the quality of apples by packing apples with functional MA films((Park et al., 2004). But there are only few reports on quality safety by analyzing the correlation between the change of reducing sugar and total sugar and preference during storage by packing Geochang, Yeongju, and Yesan apples in functional MA film. Therefore, this study aims to propose a method to secure the quality safety of apples by investigating the effect of sugar change on the preference of apples during storage by packing apples in three regions in functional MA films.
