摘要: 以阿拉伯胶(gum arabic,GA)和辛烯基琥珀酸酐(octenyl succinic anhydride,OSA)为原料,采用湿法制备辛烯基琥珀酸-阿拉伯胶酯(octenyl succinic acid-GA ester,OS-GA)。通过单因素试验和响应面分析研究OS-GA的合成工艺,并对其产物乳化性能进行了研究。结果表明:OS-GA合成的较优组合为OSA添加量3.0%(以干基GA计)、GA溶液初始质量浓度40 g/100 mL、反应体系pH 8.85、反应温度33 ℃、反应时间130 min。在此工艺条件下制备的OS-GA的辛烯基琥珀酸接入量为1.99%,其乳化能力及乳化稳定性均显著提高。

Abstract: Octenyl succinic anhydride modified-gum arabic (OS-GA) was prepared from gum arabic (GA) and octenyl succinic anhydride (OSA) by a wet method. The synthesis process was optimized by the combined use of one-factor-at-atime method and response surface methodology, and emulsification properties of the synthesized product were determined. The optimal synthesis conditions for OS-GA were determined as follows: OSA, 3.0% (based on the dry weight of GA); initial mass concentration of GA, 40 g/100 mL; pH, 8.85; reaction temperature, 33 ℃; and reaction time, 130 min. Under these conditions, the grafting rate of OS in OS-GA was 1.99%, and its emulsion capacity and emulsion stability were enhanced significantly compared with those of GA.

Key words: gum arabic, octenyl succinic anhydride, octenyl succinic acid-GA ester, response surface analysis; emulsification properties
