Cinnamon, which has been widely used historically as an herbal medicine, belongs to the Lauraceae family and is mainly found in China and some Southeast Asian countries (Rao & Gan, 2014). Cinnamon essential oil (CEO) is a volatile substance that is typically isolated from the bark of the cinnamontree (Ackermann, Aaltokorte, Jolanki, & Alanko, 2009). CEO contains a range of different aromatic compounds and terpenes, including cinnamaldehyde (70%-80%, w/w), acetophenone (0.3%-0.9%, w/w), benzaldehyde, cinnamyl acetate, and camphor (Li, Kong, & Wu, 2013). In the food industry, CEO is widely used as a spice and preservative due to its unique organoleptic, antimicrobial (Goñi et al., 2009; Zhang, Liu, Wang, Jiang, & Quek, 2016), and antioxidant properties (Özcan & Arslan., 2011). It has also been proposed that it can be used as a nutraceutical or medical agent due to its potential anticancer (Yang, Zheng, Ye, Li, & Chen, 2016) and anti-inflammatory activities (Tung, Chua, Wang, & Chang, 2008). However, CEO tends to chemically degrade when exposed to heat, light, or oxygen (Hermanto, Khasanah, Kawiji, Manuhara, & Utami, 2016), which leads to a loss in its beneficial biological activities (Turek & Stintzing, 2013). Consequently, there is a need to develop effective strategies to protect CEO from degradation during storage. Microencapsulation is the process where by a substance of interest (the "core" material) is encapsulated within another substance (the "wall material") in the form of tiny capsules (Zuidam & Shimoni, 2010). Spray drying is a commonly used technology to encapsulate fragrances, oils, and flavors because it is inexpensive,
