Physical properties of chia (Salvia hispanica L.) seeds

Dimensional specific physical properties of fan palm fruits, seeds and seed coats (Washingtonia robusta)

“…However, with an aspect ratio of over 70%, the palm fruits and seed are more likely to roll than to slide. A similar trend had been reported previously (Ixtaina et al, 2008;Mpotokwane et al, 2008). Considering the low aspect ratio (which relates the materials width to length) and sphericity, it may be deduced that those materials would slide on their flat surfaces rather than roll.…”

“…Furthermore, the shape indices indicated that the palm fruit and seed may be treated as a scalene ellipsoid for an analytical prediction of its postharvest processes. All the aspect ratios of fan palm fruit and seeds are found to be higher than those of African breadfruit (47.8), Chia seeds (62.7-65.2) and chickpea (75.6) and lower than bambaraa (84.6) (Ixtaina et al, 2008;Mpotokwane et al, 2008;Omobuwajo et al, 1999;Tabatabaeefar et al, 2003).…”

“…Considering the low aspect ratio (which relates the materials width to length) and sphericity, it may be deduced that those materials would slide on their flat surfaces rather than roll. This tendency to either roll or slide is very important in the design of hoppers, because most flat seeds slide easier than spherical seeds which roll on structural surfaces (Ixtaina et al, 2008). Furthermore, the shape indices indicated that the palm fruit and seed may be treated as a scalene ellipsoid for an analytical prediction of its postharvest processes.…”

Physicochemical characterization of chia (<i>Salvia hispanica</i>) seed oil from Yucatán, México

“…Their shapes are oval and in general, the white seeds are somewhat larger than the black ones. Ixtaina et al [4] reported length, width and thickness values of 2.11, 1.32 and 0.81 mm for dark seeds and 2.15, 1.40 and 0.83 mm for white seeds, respectively.…”

“…It also contains a high amount of antioxidants [4]. Chia seed is traditionally consumed in Mexico, the southwestern United States, and South America, but it is not widely known in Europe.…”
