脱水茭白加工工艺研究

Study on processing technology of dehydrating wild rice stem

利用微波能结合热风干燥对茭白脱水的工艺进行了初步研究。茭白切片厚度为 4mm ,经微波杀青 ,用浓度 0 0 1%EDTA、0 1%柠檬酸、0 0 2 %焦亚硫酸钠配成的护色液护色 3h ,6 5℃鼓风干燥 1 5h处理后微波干燥 ,能得到色泽度。

The technology of dehydrating wild rice stem using microwave energy in combination with hot air diying was investigated preliminarily.High whiteness,good shape and texture were obtained when wild rice stem was treated according to the following procedure:fresh wild rice stem was sliced into 4mm thick,blanched with microwave energy,soaked in mixed solutions of 0\^01%EDTA,0\^1% citric acid and 0\^02% Na\-2S\-2O\-5 for 3 hrs,dehydrated by microwave energy after hot air drying at 65℃ for 1\^5 hrs.\;
