摘　　要：以褐藻酸钠、羟丙基甲基纤维素为原材料,通过混合水平正交试验,使用溶胶、混胶、脱气、倒胶、钙化、干燥工艺制备可食性膜,研究了不同褐藻酸钠/羟丙基甲基纤维素配比、溶胶温度、氯化钙质量浓度、钙化时间、褐藻酸钠质量浓度以及羟丙基甲基纤维素质量浓度对膜性能的影响,结果显示优化工艺参数为:10mg/mL褐藻酸钠和50mg/mL羟丙基甲基纤维素按质量配比1∶1混胶,10mg/mL的氯化钙钙化10min;所得膜的厚度为0.14mm,抗拉强度为2.97 MPa,透光率为64.09%,干燥质量损失率为9.97%,人工胃液崩解时间超过24h,人工肠液崩解为2.07h。本工艺较为简单,成膜性较好,为进一步制备植源性空心硬胶囊壳奠定理论和实践基础。This paper is mainly concerned about processing conditions and the properties of the edible sodium alginate film wich was prepared by sodium alginate （SA） and hydroxypropyl methyl cellulose （HPMC） as raw materials by procedures of dissolving, mixing, degassing, pouring, calcifying and drying. The tech- nology was optimized by regulation of SA/HPMC ratio, dissolving temperature, CaCl2 concentration, calcification time, SA concentration and HPMC concentration in the orthogonal experiment. The findings indicated that the 10 mg/mL of SA and 50 mg/mL of HPMC were dissolved respectively and formed as gel solutions. The two gel solutions were mixed based on the mass ratio of 1 ： 1 and then formed film by spreading the mixed gel on the plain container. The results showed that the formed film was calcified by 10 mg/mL of CaC12 for 10 rain. The calcified edible film was analyzed to have thickness of 0.14 mm, a tensile strength of 2.97 MPa, light transmittance of 64. 09%, and drying weight loss of 9.97%. The artificial gastric juice disintegration time was found to be more than 24 h and artificial intestinal disintegration of 2.07 h. This relatively simple process has good film-forming, laid the foundation of theory and practice for further research about process of plant-derived hard capsule with sodium alginate.
