摘要
以高良姜提取物,海藻酸钠为主要原料制备涂膜剂,在常温(温度为28℃~30℃,湿度为85%~90%)下对象牙芒果进行保鲜实验,同时做空白实验和壳聚糖涂膜的阳性对照。实验结果表明高良姜提取物-海藻酸钠复合涂膜剂保鲜芒果综合效果强于空白组而弱于壳聚糖对照组。经高良姜提取物-海藻酸钠复合涂膜处理后,在常温条件下贮藏10 d,失重率为11.13%,好果率为87.5%,VC的含量为11.64 mg/100 g,可溶性固形物含量为20%,可滴定酸的含量为0.448%,总糖含量的最高值出现在第6天。
The preservation effect of Ivory mangoes was studied by coating with galangal extract-sodium alginate at room temperature(temperature 28 ℃-30 ℃,humidity for 85 %-90 %).At the same time,blank experiment and control experiment of chitosan coating were operated.The experiments showed that the preservation effect of galangal extract-sodium alginate was better than blank experiment,but worse than control experimentof chitosan coating.After 10 days,loss weigh rate of mango was 11.13 %;unvarnished rate was 87.5 %;Vitamin C content was 11.64 mg/100 g;total soluble solids content was 20 %;titratable acidity content was 0.448 %;the highest value of total sugar content was in sixth days when mango was dealed with compound coating of alangal extract and sodium alginate.
