The chocolate production process today is a marriage between technology and craftsmanship. Generally, the presence of particles above 30 µm leads to poor mouth-feel. It is perceived as gritty. Meanwhile, particles below 20 µm feels silky and smooth. Below 30 µm, 2-3 µm of a particle size difference can be detected by the tongue as a different level of smoothness. Therefore, monitoring, standardizing and setting specifications for particle size testing is a critical and necessary measure for quality control across chocolate plants.
