摘要
采用太阳能、蒸汽、微波、药物4种方法处理黄花菜,研究不同杀青方法对黄花菜营养成分的影响。结果表明:蒸汽杀青处理的黄花菜总糖和蛋白质含量高于国家标准,分别为55.66%、11.54%;太阳能杀青处理的黄花菜蛋白质含量(11.35%)高于国家标准,VC(489.0mg.kg-1)和β-胡萝卜素含量(36.5mg.kg-1)最高,而总酸度(2.90%)低于国家标准,干制黄花菜品质最优,营养成分流失最少,加工简便,且节能环保。
Four kinds of kill out methods,including solar power,vapour,micro-wave and medicinal treatment were used to treat the daylily(Hemerocallis citrina Baroni),and studied their effects on daylily nutrient.The results indicated that the total sugar and protein content of dried daylily via vapour method were 55.66 % and 11.54 % respectively,higher than the national standard.The protein content of dried daylily via solar power method was 11.35 %,higher than the national standard and its contents of VC and β-carotene were the highest,489.0 mg·kg-1 and 36.5 mg·kg-1,respectively.But its total acidity(2.90 %)was lower than the national standard.The dried daylily via kill out method of solar power had the best quality,least loss of nutrient,with easy and simple processing way.Besides,it was energy saving and friendly to environment.
