The quality concerns of each industry using wheat, corn, and soybeans are identified in chapter 4. Wheat, by its very nature, is the most complex of the three grains in terms of defining quality because of the vast array of products and processing technologies involved. Quality requirements differ not only by type and individual product, but between mills using the same type wheat to produce flour for the same type of product. Corn is somewhat less complex in that fewer products are produced and quality concerns can be traced to the individual

industries, Nevertheless, the quality required by one corn industry is not necessarily important to others, so decisions regarding corn quality must be assessed in terms of major usage. Quality concerns of different industries using wheat are somewhat offset by the fact that different types of wheat exhibit different properties. Soybean quality is the least complex, because the vast majority of soybeans are used to produce oil and meal.
