【摘要】 比较了5种大孔吸附树脂对大豆皂苷的吸附等温线、吸附容量、解吸率和吸附动力学,发现ZTC-1树脂对大豆皂苷吸附量大、解吸容易、吸附速度快,是一种良好的大豆皂苷吸附剂,AB-8树脂次之。选择ZTC-1树脂纯化大豆皂苷粗提液,得到大豆皂苷产品纯度为78.2% (干物质),回收率为93.1%。更多还原

【Abstract】 Five kinds of macroporous resins named as ZTC-1, AB-8, XAB-8, X-5 and D312 had been selected to purify soyasaponins. The comparative research on adsorption isotherm, sorption capacity, desorption ratio and sorption kinetics had been done. The results showed that ZTC-1 was an excellent adsorbent. The yield of soyasaponins extracted and purified from the defatted soybean meal with ZTC-1 resin column was 93.1%, and the content of soyasaponins is 78.2%.更多还原
