Measurements of the drop in freezing point of the milk sample or tap water outside of the milk sample

摘要

(57) relates to a method for the quantitative evaluation of the outside tap water of any contained in the milk sample, [Abstract] The present invention measures the infrared attenuation of the sample in the wavelength band of at least one (a) of this method carrying out, (b) and measurement (a), the sample on the basis of the regression coefficient which is determined in advance from multiple variable calibration relationship between the amount of the external tap water and infrared attenuation in the wavelength band of at least one it comprises a step: of quantitative evaluation of the amount of fresh water out of any. The present invention relates to similar methods for determining the freezing point depression of the sample. The invention further relates to a method for the establishment of the regression coefficients set for use in an apparatus for measuring the freezing point depression and the amount of raw water outside the milk sample.
