摘要:以阿拉伯胶和麦芽糊精为壁材,对喷雾干燥法制备余甘子核仁油微胶囊的工艺进行研究。通过单因素试验和响应面优化试验考察乳化剂添加量、阿拉伯胶与麦芽糊精质量比、芯壁比及固形物添加量对余甘子核仁油微胶囊包埋率的影响,得到最优微胶囊制备条件为乳化剂添加量1%、阿拉伯胶与麦芽糊精质量比1∶3.4、芯壁比2∶3、固形物添加量14.2%,该工艺条件下得到的余甘子核仁油微胶囊的包埋率达到(90.74±0.51)%,包埋效果好,颗粒形态完整。采用油脂氧化稳定性测定仪(Rancimat法)测定该样品的氧化诱导时间,并对微胶囊在25℃条件下的货架期进行预测发现,微胶囊的货架期为716 d,未包埋的余甘子核仁油货架期为128 d,由此可见该微胶囊具有良好的贮藏稳定性。
The purpose of this study was the optimization of the papain-catalyzed deproteinization conditions of polysaccharide from Portulaca oleracea L. (POP) by response surface methodology (RSM). Polysaccharide loss and the rate of protein removal were investigated with respect to four variables: enzyme to sample ratio, hydrolysis time, hydrolysis temperature and pH. The optimum operating conditions were obtained as follows: enzyme to sample ratio 0.2:1, hydrolysis time 60 ℃, hydrolysis temperature 3 h and pH 6. Under the optimized conditions, the deproteinization efficiency was as high as 78.22% with only 10.39% loss of the polysaccharide. Monosaccharide composition analysis by high performance liquid chromatography (HPLC) showed that the purified polysaccharide was composed of mannose, rhamnose, glucuronic acid, galacturonic acid, glucose, galactose and arabinose in a molar ratio of 5.3:5.9:1.3:27.6:1:18.8:14.6.
