Division 9.2 Calculation of the percentage of rennet whey powder in the sample:F1
United Kingdom
W = S III [E] – [1, 3 + (S III [0] – 0,9)]
where:
the percentage m/m of rennet whey in the sample [E];
the relative area of peak III of test sample [E] obtained as in 9.1.2;
represents the relative average area of peak III expressed in grams of rennet whey per 100 g determined in non-adulterated skimmed milk powder of various origins. This figure was obtained experimentally;
represents the relative area of peak III which is equal to R III × A III [0]. These values are obtained in 9.1.1 and 8.5.3 respectively;
represents the correction to be made to the relative average area 1,3 when S III [0] is not equal to 0,9. Experimentally the relative average area of peak III of the control sample [0] is 0,9.
