The particle size distribution of the microencapsulated vanillin powders were measured using a laser light diffraction particle size analyser // A small quantity of microencapsulated vanillin powder was dispersed in methanol// The mixture was stirred to attain proper obscuration and analyses were done in triplicates// Width distribution of microencapsulated vanillin particle sizes was determined through span value described by Tonon, Pedro, Grosso, and Hubinger (2012).
