- ination or wild buckwheat, must be completely removed, as the tolerance for grit and black specks is very low. The extraneous foreign material can be removed; however, if the discoloration is present within the wheat kernel, such as black point and in severe situationsmudge, it obviously becomes very difcult to eliminate the problem. Separation of longer seeds such as, oats, barley, wild oats, and those infected with ergot is particularly difcult, as durum wheat kernels are also fairly similar in length; therefore, they cannot be easily removed by machines that cause separa- tion on the basis of length, such as disk separators and indented cylinders. If not completely removed, these and other foreign materials are likely to be frag- mented in the milling process and end up as small dark specks in the nished semolina,in spite of all efforts to remove them by purication and sifting. Pasta products made from specky semolina have unattractive spots clearly visible through the transparent wrappers or windows that characterize pasta packages. Ergot is major contaminant of durum wheat. It is fungus that grows in place of kernel on the wheat oret. It is black, toxic in large amounts, and difcult to separatefrom durum wheat, because it is very similar in size and shape, but is somewhat less dense. One single ergot grain may shatter into multitude of ne dark particles if permitted to reach the break system. Barley, oats, and wild oats are difcult to remove because they are also very similar to durum wheat in size and shape, but are also slightly less dense. Stones and mudballs must be removed completely, as stones produce gritty particles and mudballs crumble and adversely affect color of the semolina. Consequently, cleaning on the basis of differences in specic gravity provides major focus in durum wheat cleaning. Blackpoint is disease that can affect durum wheat. It leaves black dots on the seed coat. If this problem is present it can be controlled, to some extent,
