# First Commission Directive of 13 November 1979 laying down Community methods of analysis for testing certain partly or wholly dehydrated preserved milk for human consumption (79/1067/EEC), Division 7.1: Method of calculation

Extent: E+W+S+N.I.

Calculate the sucrose content by means of the following formulae:
(1) v = M 100 1,08F + 1,55P
(2) S = D - 1,25l Q × V-v V × V L×M %
where:
S sucrose content;
M mass of the weighed sample in grams;
F percentage of fat in the sample;
P percentage Of protein (N x 6.38) in the sample;
V volume in ml to which the sample is diluted before filtration;
v correction in ml for the volume of the precipitate formed during clarification;
D direct polarimeter reading (polarization before inversion);
I polarimeter reading after inversion;
L length in dm of the polarimeter tube;
Q inversion factor, the values of which are given below.
Remarks:
(a) When exactly 40,0 g of condensed milk are weighed and a polarimeter with sodium light, angular degrees and a 2dm polarimeter tube at 20,0 oC ± 0,1 oC is used the sucrose content of normal condensed milk (C = 9) can be calculated from the following formula:
S = (D — 1,25 I) x (2,833 — 0,00612 F — 0,00878 P)
(b) If the invert polarization is measured at a temperature other than 20 oC, the figures should be multiplied by:
(1 + 0,0037 (T — 20).
