对影响脱水四季豆护绿效果的烫漂条件进行了试验。结果表明,最佳护绿烫漂液为浓度0.2%食用纯碱,烫漂温度为85～90℃,烫漂4min,烫漂后浸入0.1%食用纯碱溶液中10～15min。

In this paper, the effect of the scalding conditions on keeping the dehydrated string bean green was studied in detail. The optimum processing conditions were found. The concentration of edible alkali in the scalding liquid was 0.2%,the scalding temperature was 85～90℃ and the scalding time was 4 minutes. Then the string bean was penetrated into the edible alkali liquid which was 0.1% for 10～15 minutes.
