Abstract

Glucuronoxylans have been considered as an alternative polymer for petroleum polymers in coatings, films, emulsifiers, and other industries. In this study, different molecule weight glucuronoxylans were obtained through xylanase hydrolysis. Dodecenyl succinic anhydride (DDSA) was used as a modifying agent to functionalize glucuronoxylans. At the same degree of substitution (DS), higher molecule weight glucuronoxylans led to better emulsifying properties and emulsion stability. Higher molecule weight DDSA modified glucuronoxylans showed smaller droplets size, lower zeta potential, higher EA (emulsifying activity) and better emulsion stability. These results suggested that molecule weight has positive impact on the emulsifying properties of DDSA modified glucuronoxylans. Furthermore, DS had positive impact on the emulsifying properties of DDSA modified glucuronoxylans.

分子量对十二烷基丁二酸酐改性葡萄糖醛酸聚糖乳化性能的影响

在涂料、薄膜、乳化剂和其他工业中，葡萄糖醛酸氧聚糖被认为是石油聚合物的替代品。本研究通过木聚糖酶水解得到不同分子量的葡萄糖醛酸氧化酶。以十二烷基丁二酸酐(DDSA)为改性剂，对葡萄糖醛酸苷进行了官能化修饰。在相同取代度(DS)下，高分子量的葡萄糖醛酸氧基聚糖具有更好的乳化性能和乳液稳定性。高分子量DDSA修饰的葡萄糖醛酸氧聚糖具有更小的液滴大小、更低的zeta电位、更高的EA(乳化活性)和更好的乳液稳定性。结果表明，分子量对DDSA修饰的葡萄糖醛酸氧聚糖的乳化性能有正向影响。此外，DS对DDSA修饰的葡萄糖醛酸氧聚糖的乳化性能有积极的影响。
