Comparative lab results of the following flours provided by Unifine Mill LLC, obtained from Medallion Labs, Minneapolis MN and USDA National Nutrient Database for Standard Reference Legacy Release.

|Manganese||4.48mg / 100g||3.16mg / 100g||71.00%||N/A|
|Zinc||3.16mg / 100g||2.45mg / 100g||78.00%||27.00%|

*Note. While the concentrations of these nutrients are reduced under extraction, many of these elements are at significantly higher concentrations than roller-milled white flour that is completely devoid of the bran and germ and elements. While the screen size enabled extraction of 88% of the finely milled flour volume, these percentages reveal that the larger particles sifted out contained a somewhat disproportionate share of these elements.
