Abstract

Possibility of applying non-destructive methods in determination of whey solids was investigated. The non-destructive methods used were: infrared spectroscopy, cryoscopy, conductometry and gravimetric method as a referent method. With statistical interpretation of results the stochastic relation of variable between independent variable (investigated method) and dependent variable (referent method) was established. The stochastic relation showed satisfactory dependency of variables with linear equation: Y = b0X0 + b1x1 + ε. Determination coefficient verified model's efficacy. Infrared spectroscopy and cryoscopy were successful methods for determination of whey solids. Less precise were conductometry results.
