Abstract: Spray drying technique is a common industrial process in the production of powder and granules from liquid materials. The advantage of spray drying technique is not only in the ability to control the product particle size, but also good for the ability of retaining and protecting some of volatile compounds. Since, major content of seaweed is of liquid compounds, therefore, the production of seaweed powder using a spray drying technique was considered an appropriate process technique. In this study, a study on production of powder from Sabah Green Seaweed (Kappaphycus alvarezii) was conducted. A laboratory scale spray dryer (Lab Plant SD-05) was used as the main equipment for the powder production. The experimental study was conducted at various processes operating conditions and the powders produced were analyzed for moisture content, particle size and antioxidant activity. Experimental result obtained show that there are correlation between powders size, antioxidant activity and moisture content with process operation conditions. The result show that the particle size and the antioxidant activity of the powder increases with the rise of spray drying inlet temperature, whereas the moisture contents has inverse relationship to the inlet temperature. This works shown that the spray drying technique can be considered for the production of seaweed powder.
