| 摘 要： | 研究3种包装材料铝箔袋、PET塑料瓶和玻璃瓶分别对25 ℃避光贮存90 d期间冻干杨梅品质的影响。通过比较不同存放时间的冻干杨梅水分含量、色泽、花色苷含量、质构、VC含量和总酚含量变化,分析何种包装材料更适合包装冻干杨梅。结果表明:铝箔袋贮存的杨梅90 d后水分含量最低,为6.52%,色泽最红(a*值24.05),硬度为20.08 N,VC、总酚和花色苷保持的最好,分别为49.36 mg/100 g、25 μg/g和44.23 mg/100 g。其次是玻璃瓶,而PET塑料瓶效果最差。综合考虑冷冻杨梅干品质和成本,铝箔袋包装冻干杨梅优于塑料瓶和玻璃瓶包装。

| Abstract: | This investigation was aimed to study the effect of packing materials namely,aluminum foil bag,PET plastic can,glass container on the quality of vacuum-freeze dried bayberry as indicated by moisture content,color,TPA,the contents of VC,total phenols and anthocyanins. Results indicated that vacuum-freeze dried bayberry preserved by aluminum foil bag had the lowest moisture content(6.52%),color(a* value 24.05),hardness 20.08 N,the highest content of VC,polyphenols and anthocyanin(49.36 mg/100 g,25 μg/g and 44.23 mg/l00 g)preserved after 90 days. Taking into consideration of product quality and cost,aluminum foil bag was selected as the most suitable packing material for potential applications in the vacuum-freeze dried bayberry processing industry,even for other dried fruit products than glass container and PET plastic can. |
