Dairy products have become an indispensable part of citizens' lives. On the one hand,the safety of dairy products is related to the vital interests of the people,on the other hand,it is of great significance to maintain social stability. The necessity of the dairy products recall system is particularly prominent as an important defense line in the field of dairy product safety. The recall system of dairy products in China has some problems such as narrow scope of recall subjects,lack of follow-up supervision and imperfect publicity of recall information. Drawing on the successful experience of foreign food recall,the dairy product recall system is further improved by including consumers and third-party platforms into the main scope of dairy products,unifying recall standards,constructing dairy product recall supervision rules,and establishing a special dairy product recall information publicity platform,so as to better play the effect of the dairy product recall system and promote the development of food safety in China.

[Objective]To investigate the changes in nutrientional components and sensory perception of different milk-based young children formula during the accelerated test period.[Method]Analyze the changes in nutritional components of young children formula based on cow's milk,goat's milk and sheep's milk under accelerated test conditions,and conduc sensory evaluation in accordance with the RHB 204-2004 Sensory Evaluation Details for Infant Formula Milk Powder.[Result]During the accelerated test period,the nutrientional components of young children formula based on cow's milk,goat's milk and sheep's milk showed almost no attenuation and had good stability. The attenuation rate of vitamin C only in cow's milk-based and sheep's milk-based young children formula was significantly greater than that in goat's milk-based young children formula（15.65%,14.28% vs 3.98%）.All three types of young children formula exhibited good dispersibility. After 6 months of accelerated test,the cow's milk-based young children formula developed a distinct fishy odor,while the goat's milk-based and sheep's milk-based young children formula showed distinct typical flavors of goat/sheep milk.[Conclusion]During the accelerated test period,the nutrientional components in different milk-based young children formula powders were stable. However,the differences in fatty acid content in different have certain impacts on the flavor and solubility of the products. To ensure the good sensory experience of young children formula during its shelf life,measures should be taken to reduce and control fatty acid oxidation and optimize the surface composition of young children formula,thereby enhancing the stability of the particles.
