Pandan (Pandanus amaryllifolius) is commonly used as a food ingredient in Southeast Asia due to its delicious flavor, appetizing aroma and bright green colour. Pandan plant is uniquely found only in certain parts of the world. Despite its increasing popularity worldwide, its export market is limited by practical issues. One of the main problems for exporting Pandan to global market is its stability during transport. Due to the volatility of its active constituent, the functional properties of Pandan are lost during storage and shipment. In this study, we explored the ability of ultrasound processing technology to encapsulate the aromatic Pandan extract using lysozyme or chitosan as a shell material. 20 kHz ultrasonicator was used to encapsulate the pandan extract at 150 W of applied power. Two parameters, the ultrasonic probe tip and the core-to-shell ratio were varied to control the properties of the encapsulates. The diameters of the probe tip used were 0.3 and 1.0 cm. The core-to-shell volume ratios used were 1:160 and 1:40. The size distribution and the stability of the synthesized microspheres were characterized to understand and explore the possible parameters variation impact. Both size and size distribution of the microspheres were found to be influenced by the parameters varied to certain extent. The results showed that the mean size of the microspheres was generally smallest when using 1 cm probe tip with lower core-to-shell volume ratio but largest when using the 3 mm tip with higher core-to-shell volume ratio. This indicates that the sonication parameters could be fine-tuned to achieve the encapsulation of Pandan extract for storage and export. The pandan-encapsulated microspheres were also found to be stable during storage at least for one month.

香兰 ( Pandanus amaryllifolius) 因其味道鲜美、开胃的香气和鲜绿色的颜色而在东南亚普遍用作食品配料。班兰植物仅在世界某些地区独一无二。尽管其在全球范围内越来越受欢迎，但其出口市场受到实际问题的限制。将班兰出口到全球市场的主要问题之一是它在运输过程中的稳定性。由于其活性成分的挥发性，Pandan 的功能特性在储存和运输过程中会丢失。在这项研究中，我们探索了超声处理技术使用溶菌酶或壳聚糖作为壳材料封装芳香班兰提取物的能力。使用 20 kHz 超声波发生器以 150 W 的施加功率封装香兰提取物。两个参数，改变超声探头尖端和核壳比以控制封装的特性。所用探针尖端的直径为 0.3 和 1.0 cm。使用的核壳体积比为 1:160 和 1:40。表征合成微球的尺寸分布和稳定性，以了解和探索可能的参数变化影响。发现微球的尺寸和尺寸分布在一定程度上受参数变化的影响。结果表明，当使用具有较低核壳体积比的 1 cm 探针尖端时，微球的平均尺寸通常最小，而在使用具有较高核壳体积比的 3 mm 尖端时，微球的平均尺寸最大。这表明可以微调超声处理参数以实现香兰提取物的封装以进行储存和出口。还发现香兰包封的微球在至少一个月的储存期间是稳定的。
