METHOD FOR ASSESSMENT OF DRINKS QUALITY Russian patent published in 2009 - IPC G01N33/14 

FIELD: physics, measurement.

SUBSTANCE: invention is related to alcoholic beverage industry. Product samples are selected, there physical and chemical parameters P_ij are defined, where k-number of analysed parameters; n - number of analysed samples. Organoleptic assessment of samples is carried out, parameters of "ideal" sample P_ij are selected according to obtained data, physical and chemical parameters are ranged, and organoleptic assessment is carried out according to extent of significance, and significance coefficients Kp_ij are assigned to selected parameters, provided that their sum is equal to 1. Value of every sample parameter ratio to parameters of "ideal" sample is determined according to formula N_ij=p_ij/P_ij, (when P_ij≥p_ij); or N_ij= P_ij /p_ij, (when P_ij≤p_ij), product of N_ij and Kp_ij is found, products of selected Kp_ij are summed for every parameter and found N_ij, and generalised criterion of drinks quality assessment is calculated according to the following formula, comparing to value of generalised criterion for ideal sample equal to 1: for n samples, it makes it possible to more accurately define compliance of studied samples with required organoleptic and physical and chemical parameters.

EFFECT: higher validity of drinks quality analysis.
