壳聚糖/纳米二氧化钛涂膜对休眠后期马铃薯品质及生理指标的影响
Effects of Chitosan/Nano Titania Dioxide Coating on Potato Quality and Physiological Index in Late Stage of Dormancy
摘要
Abstract
In order to prolong the shelf life of potato,effects of different concentrations of titania (TiO2) combined with chitosan coating on quality and physiological indexes of potato in late stage of dormancy were studied.The results showed that compared with the control without coating,0.1% chitosan combined with 0%,1%,2% and 3% titanium dioxide coating could inhibit the decrease of soluble solids,starch, ascorbic acid and total phenol contents,slowed down the increase of polyphenol oxidase,peroxidase activi-ty and germination rate.The effect of the treatment with 0.1% chitosan and 2% titanium dioxide coating on potato was the most significant.After 8 days of storage,the potatoes didn't germinate.Compared with control,total phenol and ascorbic acid contents increased by 105.6%,18.1%;PPO and POD activities decreased by 28.1%,21.8%;the soluble solids and starch contents were 7.1% and 14.0% respectively. Sum up,0.1% chitosan combined with 2% titanium dioxide coating could keep the quality of potato in late stage and extend its shelf life.关键词
