Wettability Test Objective Aerogels will be used in a test to increase the wettability of food powder products such as Slim Fast in order to improve processing cost. Current methods for increasing wettablility in Slim Fast include adding soy lecithin, corn starch and sugar gum.
Procedure for Wettability Test Floatation Cell + Mechanical Mixer: Separated the non-wettable fraction from the wettable fraction of the Slim Fast powder in water. Test Groups: Control Test Run: NO Aerogel, Slim Fast Powder + Tap Water Aerogel Test Run: Contained 1% weight Aerogel powder to Slim Fast powder + Tap Water
Preliminary Results for Wettability Test The Slim fast containing 1% Aerogel powder improved wettability 60% compared to Slim fast without Aerogel. Material TestedGrams Floated (not dispersed in water) NO Aerogel/Slim Fast1.06 grams 1% Aerogel/Slim Fast0.42 grams
