An Optoelectromechanical Sensor for Detecting Adulteration in Anhydrous Milk Fat

This paper presents the theory, design, fabrication, and test results of a new system, which is used for the detection and measurement of adulteration of clarified butterfat, a classification of anhydrous milk fat. Detection of adulteration by 20% or more of animal body´s fat in clarified butter is very easily and economically, done. The Time period of simple harmonic motion of uniform density metallic rod, oscillating in medium from a fixed point under controlled temperature conditions, is effected by the characteristics of the medium. Experimentally, it has been verified that the relationship between time periods of oscillation of rod pendulum in medium is appreciably proportional to adulterant in the sample.
