Study of the factor which will influence the quality of the UHT milk and related measurement

This paper expatiate the main question that influence the quality of UHT sterilized milk. The main influencing factors are the quality of raw milk and some important aspects during the process of UHT sterilized milk. Analyze the questions about sterilization temperature and holding time, degassing and homogenization, aseptic transportation, aseptic packing, the process equipment about aseptic filling stage during UHT process. Refer to the structure of equipment process characteristic, find the key factors that influence the quality of UHT sterilized milk and mention the measurement of control. On the other hand , another important factor of influence the quality of UHT aseptic milk is the quality of raw milk, according to the characteristic of raw milk and process method that is used, mention the measurement of control, ensure the stability of product quality.
