摘要: 采用直接压片法生产玉米膳食纤维片。在单因素试验基础上,以压力、微晶纤维素、羧甲基淀粉钠为响应因素,脆碎度、崩解时间为响应值,运用Design-expert 7.1.6设计软件,根据Box-Behnken中心组合原理,采用三因素三水平设计研究玉米膳食纤维直接压片最佳工艺条件。结果表明:玉米膳食纤维用量67.40%、微晶纤维素用量15.90%、羧甲基淀粉钠用量16.20%、硬脂酸镁用量0.50%,片径20mm,压力20MPa时,玉米膳食纤维片脆碎度为0.739%,崩解时间为80.50s,片型完整、表面光滑,并具有较好的适口性。

Abstract: The production of corn dietary fiber tablets by a direct tabletting method was optimized by one-factor-at-a-time method and response surface methodology. The friability and disintegration time of dietary fiber tablets were individually modeled as a function of three process parameters including pressure, microcrystalline cellulose and sodium carboxymethyl starch based on a 3-variable, 3-level central composite experimental design. The models established were analyzed by response methodology to determine the optimal tabletting conditions as follows: corn dietary fiber amount 67.40%, microcrystalline cellulose amount 15.90%, carboxymethyl starch sodium amount 16.20%, magnesium stearate amount 0.50%, tablet diameter 20 mm, and pressure 20 MPa. The tablets obtained under these conditions revealed a friability of 0.739% and a disintegration time of 80.5 s, a complete shape, a smooth surface and a high palatability.
