9. General remarks U.K.

9.1. The formula for the calculation of the quantity of dough liquid is based on the following considerations: U.K.

Addition of x ml water to the equivalent of 300 g flour at 14 % moisture produces the required consistency. As in the baking test 1 kg of flour (14 % moisture basis) is used, whereas x is based on 300 g of flour, for the baking test x divided by three and multiplied by 10 g of water is needed, so 10 x/3 g.

The 430 g sugar-salt-ascorbic acid solution contains 15 g salt and 15 g sugar. This 430 g solution is included in the dough liquid. So to add 10 x/3 g water to the dough, (10 x/3 + 30) g dough liquid composed of the 430 g sugar-salt-ascorbic acid solution and an additional quantity of water must be added.

Although part of the water added with the yeast suspension is absorbed by the yeast, this suspension also contains ‘free’ water. It is arbitrarily supposed that 90 g yeast suspension contains 60 g ‘free’ water. The quantity of the dough liquid must be corrected for this 60 g of ‘free’ water in the yeast suspension, so 10 x/3 plus 30 minus 60 g must finally be added. This can be rearranged as follows: (10 x/3 + 30) - 60 = 10 x/3 - 30 = (x/3 - 3) 10 = (x - 9) 10/3, the formula given in 7.5. If, for example, a water addition x in the farinograph test was found of 165 ml, this value must be substituted in this formula, so to the 430 g sugar-salt-ascorbic acid solution water must be added to a total mass of:

(165 - 9) 10/3 = 156 × 10/3 = 520 g.

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: U.K.

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 0,5 to 0,6 % on dry matter basis.

Determine the ash content of the flour according to Annex II to Commission Regulation (EC) No 1501/95 and the moisture content according to this Regulation. Calculate the extraction

rate by the equation:

E = (((100 - f) F)/(100 - w) W) × 100 %

where:

E

=

extraction rate,

f

=

moisture of the flour,

w

=

moisture content of the wheat,

F

=

mass of flour produced with moisture content f,

W

=

mass of wheat milled with moisture content w.
