Yellow berry is an alteration of durum wheat kernels that affects flour quality and,
consequently, the quality of products like pasta. The evaluation of yellow berry
incidence in durum wheat seed stocks is still entrusted to experts, which make visual
analysis of a seed sample extracted from an enormous quantity of vegetal material.
This technique is commonly used because of their simplicity and cheapness.
Nevertheless, some disadvantages are evident, like evaluation subjectivity and the
reduced sample size analysed. Some companies have already realised efficient
apparatus for the individuation and selection of extraneous body or altered elements
in commercial goods, based on dimensional and colorimetric automatic detection
system. These evaluations are performed by dedicated hardware and software and
generally they have high costs and low accuracy. Consequently, they cannot satisfy
the exigencies of researchers and technicians.
