Effects of zeolite-based functional paper packaging on the quality of the kawanakajima white peach during storage

Abstract

The purpose of this study was to improve the shelf life of packaged peach using inorganic materials. The functional paper package consisted of 4 inorganic materials (zeolite, diatomite, bentonite, calcium carbonate). Experimental samples were paper-packaged peach (CON), functional paper-packaged peach (FUN), and expanded polyethylene terephthalate-packaged (commercial package) peach (PET). The samples were stored at 20℃ for 10 days. At every 2-3 days, the physicochemical properties, microbiological, sensory qualities of the samples were analyzed. The results showed that FUN compared to CON, significant differences were can be seen in antibacterial effect, physical characteristics (strength and hardness), and color characteristics, especially in the sensory evaluation. But FUN had no effect on weight reduction. Overall, this study showed that FUN was a means of improving the storage quality of peach.
