Abstract
AbstractThe objective of this research was to evaluate the effect of octenyl succinic anhydride (OSAn) substitution level of carbohydrate encapsulation matrices on the retention and physical characteristics of spray‐dried l‐menthol microcapsules. It was found that as OSAn substitution of carbohydrates increased, total and surface menthol appeared to increase and decrease, respectively. The particle size of the finished spray‐dried powder was influenced by spray dryer infeed solids concentration, with higher solids leading to larger particle size. Microcapsule density did not appear to be affected by OSAn substitution or carrier type. Copyright © 2008 John Wiley & Sons, Ltd.
