Fat And Protein Detection Of Milk And Food Safety Research

With the improvement of living standards, milk as a nutritious food is accepted. In recent years, the milk industry have been expanding production and sales continue to rise, but also violent milk food safety issues leak. Through the introduction of photoelectric detection technology on milk food safety issues the following work:1.To milk the most representative of pure milk, milk production processes of multiple aspects of food safety issues, typical milk production UHT process is research. Research UHT milk production process; divided according to pre-process hazard analysis for UHT milk production, the significant dangers of technology as a key technology; For a critical process can take appropriate measures if hazard control in the acceptable range, then recognize it as a node detection can be introduced.2.The detection target determining the fat content of milk protein detection method, detection method, the detection node specific location; design detecting apparatus comprising:a light source driving circuit, the photoelectric conversion receiver, preamplifier, analog to digital conversion circuit, the temperature control circuit, the smallest systems, human-machine interface and communication circuit; analysis to detect the problems, complete the main part of the software process design and test data.3.Comprehensive hazard analysis before applying the method described importance of milk fat and milk protein quality and safety of the relationship, Milk food safety class division based on test results.In summary, this paper fat milk protein and thus detect the protein in milk fat and food safety made a study of the correlation.
