    Abstract： Food additives play a significant role in improving food quality and extending shelf life， but the safety of their processing has attracted much attention. In this paper， the effects of processing conditions such as temperature， pH， and pressure on the stability and function of additives are analyzed， and the risk of by-product formation is revealed. At the same time， the safety threshold assessment method was introduced from multiple perspectives， and countermeasures and suggestions such as optimizing processing technology， developing new additives， promoting dynamic monitoring technology， and improving regulations and education methods were put forward， aiming to provide reference for food safety and industrial development. ......
