摘要:

采用羧甲基纤维素钠(CMC)、高直链玉米淀粉(HAMS)和可溶性淀粉(SS)为膜材料,甘油(Gl)为增塑剂,以溶解时间为筛选指标优化材料配比,后使用双螺杆挤出机、压延机和自动包装机对膜进行制备和包装,通过测定膜的各项性能来确定不同制膜参数对膜性能的影响。结果表明,当HACS为0.50 g,SS为0.50 g,Gl为1.25 g,CMC为4.00 g时,膜的溶解时间达到最短,为18.86 s。在挤出温度为70 °C、压延温度为100 °C时,膜的各项性能达到最佳。此外,在热封条件为110 ℃、6 s时,热封强度达到最高,为(8.61±0.52) N/15 mm。

Abstract:

This study developed an instant edible film using carboxymethyl cellulose sodium (CMC), high⁃amylose maize starch (HAMS), and soluble starch (SS) as the matrix, with glycerol (Gl) as a plasticizer. The material ratios were first optimized based on dissolution time, followed by film preparation via twin⁃screw extrusion, calendering, and automated packaging. Key process parameters, including extrusion temperature, rolling temperature, and heat⁃sealing conditions, were systematically evaluated for their effects on film properties. The optimal formulation (0.50 g HAMS, 0.50 g SS, 1.25 g Gl, and 4.00 g CMC) achieved the shortest dissolution time (18.86 s). Film properties were maximized at an extrusion temperature of 70 ℃ and a rolling temperature of 100 ℃. Furthermore, heat⁃sealing at 110°C for 6 s yielded the highest sealing strength (8.61±0.52) N/(15 mm).

Key words: edible film, instant, screw extrusion, rolling, heat sealing
