At least (or best) use a water solution or dispersion. Potential antimicrobial efficacy in food will not disperse.

You can use DMSO or other organic solvents but your data will be effectively meaaningless technical trivia.

@Asem M Abdelshafy, what do you mean by "Liquid Food"?

Asem M Abdelshafy

Riaz A. Khan

It's better to be transparent or homogeneous without particulate matter can be opaque also, viscosity is another important factor for the anti-microbial testings. As Phil says, at least an aqueous solution is needed!
