摘要本发明涉及新资源食品加工技术领域,更具体地说,是涉及一种以干菊芋为原料制备菊粉的方法。以菊芋或菊苣为原料,依次经过脱皮,切丁,闪蒸干燥,得到干菊芋丁,接着进行连续逆流提取,提取液经过除杂和活性炭脱色,进入离子树脂交换柱脱盐后经过纳滤膜浓缩,再喷雾干燥得到高纯度的菊粉;所述的逆流提取采用纯净水,固液比为1:5~10,浸提温度为80~100℃,提取时间为1~2小时;除杂、脱色的过程中,首先加入Ca(OH)2固体,调节体系的pH=10~12,30分钟后通入CO2气体使体系的PH=7~8,将沉淀过滤后,加入活性炭脱色30分钟,滤掉活性炭,滤液备用;活性炭的加入量为体系总重量的1~5‰。
其他摘要The invention relates to the technical field of new resource food processing, in particular to an inulin preparing method taking dried jerusalem artichoke as the raw material. The jerusalem artichoke or chicory is taken as the raw material and is subjected sequentially to peeling, dicing and expansion drying, and dried jerusalem artichoke cubes are obtained; then continuous countercurrent extraction is performed; and an extracting solution enters an ion resin-column for desalination after being subjected to impurity removal and activated carbon decoloration, then is concentrated by a nanofiltration membrane, and then is subjected to spray drying, therefore, high-purity inulin is obtained. The countercurrent extraction adopts purified water, the solid-to-liquid ratio is 1 : (5-10), the extraction temperature ranges from 80 DEG C to 100 DEG C, and the extraction time is one hour to two hours; in the processes of impurity removal and decoloration, Ca(OH)2 solids are added first, the pH of the system is regulated to be 10 to 12, CO2 gas is introduced after 30 minutes to enable the PH of the system to be 7 to 8, precipitates are filtered, activated carbon is added for 30 minutes of decoloration and then is filtered out, and a filtrate is reserved; and the adding amount of the activated carbon is 1-5 per thousand of the total weight of the system.
