ABSTRACT
In order to improve the quality of frozen dough, a calcium alginate-coated sodium alginate/trehalose/wheat starch ternary complex was designed in this paper. The ternary complex was added to dough, and the dough quality were measured after 0-30 d of frozen storage. The XRD and FT-IR results showed the ternary complex was mainly starchy crystal. The TGA curves showed the starting (To), peak (Tp) and termination temperature (Tc) were increased. The interaction between sodium alginate and trehalose enhanced the thermal performance of ternary complex. As the ternary complex addition to dough increased, the maximum ice crystal formation zone of the frozen dough passed faster, resulting in more uniform and smaller ice crystals. The dough with 0.8% addition contained more bound water and had better hardness, springiness and cohesiveness. In conclusion, the study provides a novel insight and understanding for the development of ternary complex as food additives in frozen food industry.
