Abstract: A water-retention agent for improving the quality of quick-frozen steamed breads after microwave reheating was prepared from several improvers such as sodium alginate, gellan gum and calcium stearoyl lactylate (CSL). The optimized water-retention agent was composed of 0.37% sodium alginate, 0.15% gellan gum and 0.21% CSL as determined using response surface methodology. The observed weight loss rate of quick-frozen steamed breads with the addition of the optimized water-retention agent after microwave reheating was 6.02%, which was close to the predicted value of 6.01%. In conclusion, the optimal water-retention agent was reliable.
