- Abstract
Rapid and safe detection of contactless liquid components is an important technological development priority for milk and food safety. However, there is few practical methods to detect fat or protein content by non-destructive methods. Herein, we present a simple and rapid method for the determination of fat and protein content in milk products based on the laser scattering light theory that was developed. The intensities of the transmitted light and 90° scattered light with respect to transmission direction are collected and processed. The fat contents of 40 milk samples determined by the transmitted light method were less than 10% error. The scattering light method also accurately represented the component of milk. In this paper, the theory and operating principle of the instrument are introduced. Through data analysis and graph illustration, concrete schemes for testing the milk component are given. The method we used is real-time and satisfies online requirements for milk products. The results of this study have great potential in employing one low-cost technology for fresh milk content analysis.
