Division 9.2 The method is not directly applicable to wheat. The procedure to be followed for characterising the baking properties of wheat is as follows:
United Kingdom
Clean the wheat sample, and determine the moisture content of the cleaned wheat. If the moisture content is within the range 15,0 % to 16,0 %, do not temper the wheat. If the moisture content is outside this range, adjust the moisture content to 15,5 ± 0,5 %, at least three hours prior to milling.
Mill the wheat into flour using a Buehler laboratory mill MLU 202 or a Brabender Quadrumat Senior mill or similar equipment having the same characteristics.
Choose a milling procedure that yields a flour of minimum 72 % extraction, with an ash content of 0,50 to 0,60 % on dry matter basis.
Determine the ash content of the flour according to Annex II to Commission Regulation (EU) No 234/2010f1 and the moisture content according to this Regulation. Calculate the extraction rate by the equation:
E = (((100 – f) F)/(100 – w) W) × 100 %
where:
extraction rate,
moisture of the flour,
moisture content of the wheat,
mass of flour produced with moisture content f,
mass of wheat milled with moisture content w.
