改性蜡质玉米淀粉稳定Pickering乳液的制备及应用
Preparation and application of Pickering emulsion stabilized by modified waxy maize starch
摘要
Abstract
The waxy maize starch (WS) was hydrophobically modified by octenyl succinic anhydride (OSA) to prepare the modified waxy maize starch (OSA-WS). Stable Pickering emulsions were prepared by using OSA-WS with different degree of substitution (DS). The DS, reaction efficiency (RE) and three-phase contact angle of OSA-WS were measured. The OSA-WS was characterized by FT-IR, XRD and SEM. The results show that, by reacting with the hydroxyl groups on the surface of starch, OSA has been successfully grafted without changing the granule of starch. The emulsifying ability of OSA-WS becomes stronger with larger DS, thus the storage stability of Pickering emulsion is also increased with DS. The Pickering emulsion emulsified by OSA-WS was then applied in the transdermal transport of coenzyme Q10. Compared with the oil solution of coenzyme Q10, the Pickering emulsion containing coenzyme Q10 is more favorable for transdermal transport of coenzyme Q10.关键词
