The invention provides a method for inhibiting retrogradation of instant rice. Trehalose is a safe and reliable natural anti-retrogradation agent, which is lower in sweetness than sucrose and free of toxic effects to the human body. For the trehalose is small in molecular weight and relatively high in dissolubility, the trehalose is capable of relatively well infiltrating into pores of the rice grains when a trehalose solution is used for wetting the rice. At the same time, a certain pressure is exerted on the rice by ultrahigh pressure equipment, so that the trehalose is promoted to infiltrate into the pores of the rice grains by the ultrahigh pressure. The trehalose molecules and amylose molecules combine fully so as to form conjugant, so that steric hindrance is increased and starch molecular rearrangement is influenced; thus, re-crystallization degree of the starch is delayed, and retrogradation phenomenon of the rice is thereby inhibited. The rice treated by controlling trehalose solution concentration, wetting temperature, high-pressure treatment pressure and time is then cooked, so that ultrahigh pressure-synergic trehalose infiltrated instant rice with good edible qualities and obvious retrogradation-resistant effects is prepared. Being stored at 4 DEG C for 30 days, etrogradation enthalpy of the prepared instant rice is 3.42J/kg, which is 1.19J/kg lower than the etrogradation enthalpy of common instant rice; and bound water content of the prepared instant rice is 12.7%, which is 2.3% higher than the bound water content of common rice.
