Study on the multiple coating material of chitosan, siox nanoparticals and single stearic acid glycerine ester in the preservation of jinqiu pear

摘要

This study compared the physical and antibacterial capability of chitosan, chitosan/ SiOx nanoparticals and chitosan/ SiOx nanoparticals/ glyeml monstearate respectively. Three solutions were coated on the surface of Jinqiu pear to form film, comparing the effect of preserving by measuring the hardness, water content, total sugar, total acids, vitamin C content. The results indicated that: SiOx nanoparticals and glyeml monstearate can take effect on the enhancement of the physical and antibacterial capability, and intensify the effect of preserving.
