The physical properties of seeds have an influence on working parameters of equipments and are essential for designing them and facilities for harvest, transport, separation, drying, aeration, storage and processing. Some physical properties depend on orthogonal dimensions. Quinoa (Chenopodium quinoa Willd.) is characterized by its very small seed size. The aim of this work was to determine physical characteristics of quinoa seeds by digital processing of images. Computers, digital cameras and scanner were employed. Two samples of seeds were used. The first sample was used for software (PHOTO-PAINT, Photoshop, Paint, SmartGrain, GrainScan) testing and for comparing, and the second sample for measurement of dimensions with PHOTO-PAINT. Grains and flour color were determined with Photoshop (first sample). There was statistically significant difference (p < 0.05) between subsample of five grains of the first sample for length and width variables, and there was no significant difference (p > 0.05) between programs (PHOTO-PAINT, SmartGrain, GrainScan). The values of the colorimetric coordinates were L* 70, a* 8, b* 44 and L* 71, a* 3, b* 34 for grains and flour, respectively. The second sample presented average values of 2.3638, 2.0129 and 1.0605 mm for length, width and thickness, respectively.
