THE APPLICATION OF THE SCATTERED LIGHT TO TRANSMITTED LIGHT RATE IN THE MILK CONSTITUENTS MEASUREMENT

摘要

This paper presents a new method to measure the constituents of the milk, which uses the scattered light to transmitted light rate of the laser(called s-t rate for short) to detect the protein and fat content of the milk. The basic theory is discussed in the test in detail and the feasibility of the plan is analyzed. A relation curve between the fat and protein of milk and the ratio is built by multiple linear regression method. The uncertainty of the result is mentioned in the paper.
