摘要: 魔芋葡甘聚糖脱乙酰改性后成膜,与未改性膜相比,改性膜的强度、抗水性及耐洗刷性显著提高。用红外光谱、X-射线和扫描电镜分析了膜的结构,阐明了结构和功能的关系,并对改性膜作了常温涂膜保鲜实验,结果表明,改性膜对果蔬有一定保鲜作用。

Abstract: Konjac glucomannan (KGM) was deacetylized for membrane. The membranes made of denatured KGM showed better tensile strength, water resistance and water-cleansing endurance than those of undenatured KGM. By means of infrared absorption spectroscopy, X-ray diffraction and seanning electron microseope, the relationship between structures and func- tional properties was discussed. A study on the conservation of fruit by modified konjac glucomannan was carried out under room temperature. The results showed that the modified konjac glucomannan had better fresh-keeping efficacy.
