摘  要:
聚对苯二甲酸乙二醇酯(PET)具有稳定、质轻、价廉等多种优点而作为饮料包装材料广为使用,但PET瓶的气体阻隔性较传统玻璃瓶差,因此,提高PET瓶的气体阻隔性、提升饮料产品品质是本研究的初衷。本研究通过以两种添加阻隔材料(加吸氧剂、内涂层)、一种多层PET瓶及普通PET瓶为包装容器,选择100%橙汁为研究对象,研究不同温度条件下,100%橙汁储藏过程中VC含量和颜色的变化情况,发现四种PET瓶对VC和色泽保持的顺序为:多层PET瓶>内涂层PET瓶>含吸氧剂PET瓶>普通PET瓶,且果汁产品应尽量在4℃存放。

摘  要:
Polyethylene terephthalate(PET) has many merits,such as chemical stable,light,cheap,etc.,and has been widely applied in soft drink industry. However,the gas permeability of PET is still inferior to that of glass. Improving the gas barrier property of PET and the quality of juice beverages is a major purpose of this project. An experiment for determining vitamin C and color difference of 100% orange juice,which was packaged in four different PET bottles(one layer PET bottle,multilayer PET bottle,oxygen absorbent added PET bottle,and inner coating PET bottle) and stored at three temperature levels(4,20,37℃),was carried out. The protective effects of four PET bottles on the concentration of vitamin C and color were topped by multilayer PET bottle,followed by inner coating PET bottle,and then oxygen absorbent added PET bottle. The least protective package was single layer PET bottle. The results also recommended the juice products should be stored at 4℃.
