The effect of different calcium chloride concentration, reaction time and neutralized acid on yield of tagatose was investigated by single factor tests. Results showed that the condition, such as calcium chloride (0.01～0.03 mol/L), reaction time(20～40 min), acetum, carbon dioxide, phosphate acid to synthesize tagatose was suitable.
