Should falling number and DON be grading factors?

Expensive machines would replace visual assessments of sprout and fusarium damage

Should falling number and deoxynivalenol (DON) be official grain-grading factors? The Canadian Grain Commission (CGC) is asking the grain industry for opinions before May 10. Both factors are included now, but through visual proxies — sprout damage for falling number and fusarium-damaged kernels for DON. They aren’t as accurate as machine measurements, but they are

Grain grading revamp may add falling number, DON as factors

Two significant grain specs that aren’t yet factors for a crop’s official grade are now under consideration to join that official list. The Canadian Grain Commission on Monday put out a call for “grain sector stakeholders” to submit their views before May 10 on a proposal for falling number and deoxynivalenol (DON) to both become

Subjective? Not exactly

Western Canada’s wheat-grading system is probably more objective than you think

For 40 years Western Canada’s grain industry has dreamed about the black box — an affordable machine that would take a handful of wheat and quickly and accurately spit out its end-use quality on the elevator driveway. Like flying cars and cellulosic ethanol, it’s just around the corner, but never arrives. The black box is

Rapid Visco Analyzers are just one small step towards the longed-for ‘black box’ for grain testing.

Falling number, objective grain-grading debate not new

The grain industry explored machine testing more than a decade ago

Calls for “objective” grain grading on the elevator driveway, especially for falling number, have been around for years, ebbing and flowing with the quality of the wheat crop. These days it’s the Alberta Grain Commission and Western Canadian Wheat Growers Association (WCWGA) advocating for the change. They say since grain companies sell wheat to customers


The Alberta Wheat Commission wants wheat grading to be less subjective and more objective.

Wheat Commission asks CGC for changes to wheat grading

The AWC says instrument-measured falling number and DON levels should replace 
visual proxies based on sprouting and fusarium-damaged kernels, respectively

The Canadian Grain Commission (CGC) says it will look into the merits of including falling number and DON measurements as part of official western Canadian wheat grades, as requested by the Alberta Wheat Commission (AWC) last week. “Our GRL (Grain Research Laboratory) and Industry services officials will establish a team to look at implementing changes
