摘要
为明确不同温度和湿度环境下薏米糠油微胶囊的释放性能,试验探究了薏米糠油微胶囊在不同贮藏条件下的释放动力学。引入Avrami’s公式对薏米糠油微胶囊在不同温度和湿度条件下芯材释放率的变化进行了研究,并对其释放速率常数和释放机制参数进行了分析。结果表明,薏米糠油微胶囊释放动力学的拟合程度较高,R~2均大于0.97。在4、25℃以及相对湿度为32%、54%时,其释放机制参数介于0.54~1之间,介于扩散限制动力学和一级释放动力学之间;而在40℃以及85%的相对湿度环境中,释放机制参数均大于1,属于一级释放动力学。释放机制参数和释放速率常数随着贮藏温度和相对湿度的升高而增加。因此,在低温和干燥条件下能更好地保存薏米糠油微胶囊。
The release properties of adlay bran oil microcapsule were evaluated under different storage conditions in this paper. Avrami's formula was applied to analyze the release kinetics and measure the release mechanism parameters and release rate constant at different levels of temperatures and relative humidity. The results indicated that release kinetic equations were significant and credible, whose R~2 were both greater than 0.97. And the release mechanism parameters were between 0.54 and 1 under the conditions of 4, 25 ℃ and 32%, 54% relative humidity, which belonged to the diffusion-limited kinetics and first grade release. The release kinetic at 40 ℃ and at 85% relative humidity was both turned out to be the first grade release. In addition, the release rate of microcapsule speeded up with the temperature(relative humidity) increasing gradually. So, the microcapsule powder should be persevered in low temperature and humidity in order to improve the storage stability of adlay bran oil microcapsule.
