Abstract: The stability of submicron β-carotene emulsion under different conditions was studied.Results showed that long time direct irradiation of natural light outdoors or high temperature could affect on stability of β-carotene emulsion,but the scattered light indoors did not make any difference to it.β-carotene emulsion was quite stable in the environment of pH3~9.Metal ions such as Fe2+,Zn2+,Mg2+ and Ca2+ except Fe3+ and Cu2+ had little influence on stability ofβ-carotene emulsion.The effect of oxidant,reducer,sucrose,dextrose,citric acid,vitamin C,Na+,K+ and preservative on β-carotene emulsion was very little.
