The effect of different salt concentrations (2%, 1.5%, and 1%) and particle sizes (nano-spray dried salt, microsalt, and regular salt) at the surface of cheese crackers on physicochemical characteristics of the crackers was evaluated. The w a and color values for all treatments of cheese crackers increased from 1 week to 4 months. The reduction of 25% and 50% salt content in cheese crackers through use of nano-spray dried salt did not adversely influence the physicochemical attributes.
