Abstract
The formula using phase change materials KC1 solution or NaCl solution as temperature regulators for food storage were optimized. The super cooling phenomenon was alleviated by application of artificial nucleation agents, and proper carrier was selected. The result showed that 1% SiO2 and 0.1% CuS can minimize the super cooling phenomenon in KCL solution, 3% Na2B4O7 can better alleviate the super cooling phenomenon. Both of them can be used as artificial nucleation agents. The water absorbing capacity of Super-absorbent Polymers(SAP) decreased rapidly with the increase of ion concentration. The absorbing rate for 1.99% Nad solution was 621.47 g/g and that for 9.91% KC1 solution was 63.83 g/g. The SAP and artificial nucleation agents had little impact on the thermodynamic characteristics of salt solution and can be used as a carrier of CTESM and protective agent of super-cooling. Further studies showed that the use of Cold Thermal Energy Storage Material (CTESM) (9.91%KCl+SAP+l%SiO2) can slow the rigidity falling of Ice-cream and Tangyuan in room temperature, keep their sensory appearance and maintain their commercial value. CTESM displayed good temperature regulating property, It can keep the temperature inside the package within the set range for a longer time.关键词
