Quality Monitoring of Raw Milk in Shanghai and Comparison with Limit Standards in Developed Dairy Countries
To understand the quality of raw milk in Shanghai and it's differences from developed countries in the dairy industry,this study focused on raw milk samples from 22 pastures in Shanghai.During 2018 to the first half of 2023,more than 30000 batches of raw milk samples were collected and subjected to normalized monitoring of four indicators,including fat,protein,somatic cells,and total bacterial count.The main monitoring indicators were statistically analyzed,compare with the limit standards for raw milk in developed dairy countries.The results show that the average fat content in raw milk is≥3.77%,and the average protein content is≥3.25%,all of which meet the limits of Chinese standards.The average value of total bacterial count is≤2×104CFU/mL,which is far below the national standard limit.The overall average value of somatic cell count is stable,around 200000/mL.Compared and analyzed with the limit standards for raw milk in other countries,except for foreign countries,the average fat content in raw milk in Shanghai has reached the international level,the average bacterial count and somatic cell count content have reached other national standards,and the average protein content is slightly lower than the Italian limit standard by 0.01%.
