Soybean mechanical damage detection
2000
VanUtrecht, D. | Bern, C.J. | Rukunudin, I.H.
The sodium hypochlorite and indoxyl acetate tests were compared as methods for quantifying the mechanical damage of soybeans. These methods were selected from six described in the literature. Soybeans at 7 and 21% moisture content were damaged in a Stein Breakage Tester and the remaining whole soybeans were subjected to the two tests. Sodium hypochlorite indicates damage by causing soybeans with cracked hulls to swell whereas the indoxyl acetate test utilizes a dye to stain soybeans with scratched or cracked hulls. The indoxyl acetate test was found to be more sensitive, but the sodium hypochlorite test yielded more consistent data. The hypochlorite test was selected as a suitable test for soybean mechanical damage quantification.
