榛子油微胶囊的制备及其稳定性研究

Preparation and Stability of Hazelnut Oil Microcapsules

  • 摘要: 为缓解榛子油的氧化速度,增加储藏期和扩大其应用范围,本研究以β-环糊精(β-cyclodextrin, β-CD)为壁材,采用超声波辅助分子包埋法制备榛子油微胶囊,通过响应面法优化了微胶囊的工艺条件,同时对其理化性质进行了测定。结果表明:当壁材浓度(H2O/β-CD)为16:1、壁芯材比例为5:1、包埋时间为62 min和包埋温度为59.3 ℃时,微胶囊的包埋率达到69.18%,产率达到59.74%。微胶囊的平均粒径为880.4 nm,水分含量为2.85%,溶解度为55.95%,休止角为42.49°。通过扫描电镜、红外光谱和热重分析等结果表明,微胶囊为块状、菱形片状或不规则柱状结构,包埋物已形成,同时具有良好的热稳定性。加速氧化实验表明,微胶囊化可以有效减缓榛子油的氧化速度,延长货架期,扩大其应用范围。

     

    Abstract: In order to alleviate the oxidation rate of hazelnut oil, increase the storage period and expand its application range, this study used β-cyclodextrin (β-CD) as the wall material and used the ultrasonic-assisted molecular embedding method to prepare hazelnut oil microcapsules, the process conditions of the microcapsules were optimized by response surface method, and their physical and chemical properties were measured at the same time. The results showed that when the wall material concentration (H2O/β-CD) was 16:1, the wall-to-core ratio was 5:1, the embedding time was 62 min, and the embedding temperature was 59.3 ℃, the embedding rate of microcapsules was up to 69.18%, and the yield rate reached 59.74%. The average particle size of the microcapsules was 880.4 nm, the moisture content was 2.85%, the solubility was 55.95%, and the angle of repose was 42.49°. The results of scanning electron microscopy, infrared spectroscopy and thermogravimetric analysis showed that the microcapsules had a block, diamond-shaped flake or irregular columnar structure, the embedded material had been formed, and had good thermal stability. Accelerated oxidation experiments showed that microencapsulation could effectively slow down the oxidation rate of hazelnut oil, extend the shelf life, and expand its application range.
