The implications of frequently encountered grading factors on the processing quality of common wheat

5. Concluding remarks

It is important to realize that when wheat growing or harvesting conditions are poor resulting in physical damage, a properly developed grading system will protect the processing quality of the wheat. Numerical grading systems such as those used by Canada and the United States, which have constant grade specifications year to year, insure that the quality of a given grade is consistent. In a bad year it is mainly the proportion of top-grade wheat that is reduced.

Grade specifications among wheat producing countries evolve in response to the implications of various grading factors on wheat milling and end-use quality. Millers can ensure that minimum quality standards will be met by specifying the appropriate grade. When the miller is not familiar with the relative quality of the milling grades being offered by the supplier, or if the supplier does not have a well developed grading system, the miller can demand that the supplier meet a list of specifications, thereby insuring that quality expectations are met.
