The aim of this study was to evaluate the effect of the size of mascavo sugar crystals in their instrumental and sensory color. Nine sugar samples were used, sieved, and separated by meshes of 600, 425, and 300 µm. For the instrumental color analysis, a portable colorimeter was used, and 20 untrained panelists participated in the sensory analysis of color difference. The original samples were evaluated regarding moisture, polarization, and ashes, and the average mesh aperture and hue value calculations were estimated. Seven of the nine sugar samples evaluated were retained in three meshes. The largest sugar fractions were evaluated as darker (600 µm) in the instrumental analysis and perceived by the panelists with higher color intensity. The alteration in sugar crystal size changed color, and the most impactful variable in differentiating sensory color between meshes for each sugar sample was the average aperture, indicating that luminosity and hue did not present discriminatory power between the different granulometries, but they are potential indicators of appearance difference between the samples without sieving.
