Abstract

Propolis, which is a bee glue is potentially a useful food additive since it contains antioxidant and preservative-like properties. However, its application in the food industry remains limited, due to its strong taste and low solubility. Microencapsulation is a technique that can improve its characteristics and the most widely used is spray drying. To obtain a spray-dried product with desired properties, optimization of both the encapsulating materials and equipment operating conditions are crucial. In this review, the use of different wall materials and operational conditions for spray drying of propolis are discussed, in order to guide selection of these parameters to obtain optimal spray dried microcapsules. In addition, comparison with other microencapsulation techniques is also discussed and pertinent industrial applications of spray-dried propolis given.

摘要

蜂胶是一种蜂胶，可能是一种有用的食品添加剂，因为它含有抗氧化剂和类似防腐剂的特性。然而，由于其强烈的味道和低溶解度，其在食品工业中的应用仍然有限。微囊化是一种可以改善其特性的技术，应用最广泛的是喷雾干燥。为了获得具有所需性能的喷雾干燥产品，优化封装材料和设备操作条件至关重要。在这篇综述中，讨论了蜂胶喷雾干燥的不同壁材和操作条件的使用，以指导这些参数的选择，以获得最佳的喷雾干燥微胶囊。此外，
