Research on Theory and Experiment of Milk Ingredients Analysis with Laser

Abstract

In this paper, the laser is used as light source and interacted with the solution of milk powder; scattered light-to-transmitted light ratio is used to characterize the milk macromolecules. At first, this paper analyzes the theory of scattered light-to-transmitted light ratio，and a relation model is preliminarily built between the macromolecules and the ratio, then the parameters of the model are fitted through self-made experimental device. The relation model between the fat and protein of milk and the ratio is established.
