Stability 1. Under normal circumstances, it will not decompose and there is no dangerous reaction.

The hue is hardly affected by pH, and it is more stable than β-carotene in acidic and alkaline media, and its yellowness is more vivid when alkaline. The maximum absorption wavelength is 440nm. Salt resistance, reduction resistance, and microbial resistance are all good. Heat resistance and light resistance are poor in acidic time, and it is resistant to metal ions (other than iron, it turns black when met by iron). It is relatively stable when stained with starch and protein, and it is not stable enough in aqueous solution.
