  • Method and apparatus for determining the constituents of dairy products
    Patent number: 5258620
    Abstract: A sample having a specific optical path length of 1 to 15 mm is irradiated with near infrared of two or more wavelengths selected from 700 to 1200 nm to determine constituents of dairy products. Preferably, a pair of specific wavelengths comprise a first wavelength having a high correlation with a target constituent and a second wavelength having a low correlation with the target constituent or comprise wavelengths both having high correlations with the target constitutent. Quantities of near infrared of these two specific wavelengths transmitted by the sample are measured to determine absorbencies and a multiple linear regression equation is used to calculate the constituent on the basis of the absorbencies.
