Microstructural and rheological characteristics of dark, milk and white chocolate: A comparative study

Results showed that white chocolate, with the highest amount of fat in formulation, had the smallest sized particles, the less aggregate structure and the lowest yield stress, viscosity and thixotropic values. Dark chocolate samples instead presented the highest aggregate structure, with less void spaces between particles that involved the highest rheological parameter values. Milk chocolate matrix exhibited intermediate microstructural and rheological characteristics compared to dark and white chocolate ones.
