Effect of cloudy agents on the stability and opacity of cloudy emulsions for soft drinks

Summary Droplets with different sizes scatter light at different wavelengths. A droplet size index (R) was developed for predicting emulsion stability and absorbance of light at 660 nm was used to evaluate the opacity of the system. Various cloudy agents were tested on both stability and cloudiness of emulsions. The presence of emulsifiers and gums affected both the stability and opacity. Best conditions for high stability and opacity were found using combinations of ester gums and emulsifiers.
