The sappanwood extract enriched by brazilin can be used for a natural coloring agent in food and beverages. The extract is produced in the form of dry powder for consumer convenience as well as prolonging storage life. Currently, the sappanwood extract drying still deals with the product sticky that inhibit water transport in drying. As a result, the drying process needs long time to get the moisture content below 10%. The extract drying with carrier agent is an option to break the product sticky and to enlarge the surface area for water transport. This paper discusses the effect of carrier agent arabic gum and maltodextrin on sappanwood extract drying with air dehumidification. As a response, the moisture content in the extract was observed every 15 minutes and the average drying rate was estimated. Results showed that, the carrier agent improves drying rate significantly. The average drying time can be 1 hours shorter than that of without a carrier agent. The drying process was faster at higher temperature.
