1Microencapsulation of nutmeg essential oil by spray-drying with different wall materials显示文摘Nutmeg essential oil with volatile components is sensitive to oxygen, light, water and high temperature. Spray-drying is widely used as an encapsulation technique for improving compound stability during processing and storage. In this study, influence of encapsulated matrix on spray-dried nutmeg essential oil microcapsule was investigated using blends of maltodextrin and either gum Arabic(GA-MD), or octenyl succinic acid modified starch(OSA-MD) as wall materials. Characteristics of spray-dried powders from these 2 wall materials were evaluated and compared. Powder property analysis indicated that GA-MD microcapsules presented larger size, higher moisture and poorer flowability compared with OSA-MD microcapsules. Fourier transforms infrared spectroscopy and thermogravimetric analysis showed that both GA-MD and OSA-MD microcapsules improved the stability of nutmeg essential oil. However, GA-MD microcapsules exhibited higher storage stability than OSA-MD microcapsules. This research provided theoretical foundation for wall material choice of microcapsule and nutmeg essential oil utilization in food industry.Xuyan Dong Bangfu Wu Qianchun Deng Fang Wei Hong Chen Chen Yang Renhuai Cong Chayan Wan Xin Lv Fenghong Huang 2018Oil Crop Science2018,3,4:2
