摘要: 表面脱乙酰魔芋及壳聚糖包埋魔芋解决了人体摄入魔芋的难题并保留了魔芋葡甘聚糖的优良特性。制备两种魔芋产品并用红外光谱仪进行结构表征，为比较表面脱乙酰魔芋及壳聚糖包埋魔芋吸附性能差异，进行体外模拟吸附实验探究了两种产品对高血脂代表物脂质、胆固醇和重金属离子Pb2+以及Ca2+的吸附能力。结果表明：表面脱乙酰魔芋及壳聚糖包埋魔芋对脂质、胆固醇及重金属离子有良好吸附能力，且在不同吸附质浓度下，两种产品呈现不同的吸附优势。其中壳聚糖包埋魔芋对饱和脂肪的吸附量到达0.700 g/g，对胆固醇和Pb2+的最大吸附量分别为134.69 mg/g、133.84 mg/g。
Abstract: Surface deacetylated konjac glucomannan and chitosan coated konjac glucomannan solve the prob-lem of human body ingesting konjac and retain the excellent properties of konjac glucomannan. Two kinds of konjac products were prepared and characterized by infrared spectroscopy. In order to compare the adsorption properties of surface deacetylated konjac glucomannan and chitosan coated konjac glucomannan, simulated adsorption experiments were conducted to explore the ad-sorption capacity of the two products on lipids, cholesterol and heavy metal ions Pb2+ and Ca2+. The results showed that the surface deacetylated konjac glucomannan and chitosan coated konjac glu-comannan have good adsorption capacity on lipids, cholesterol and heavy metal ions, and the ad-sorption advantages of the two products were different at different adsorbent concentrations. Among them, the adsorption capacity of hitosan coated konjac glucomannan for saturated fat reached 0.700 g/g, and the maximum adsorption capacity for cholesterol and Pb2+ was 134.69 mg/g and 133.84 mg/g, respectively.
