Abstract
In view of the low content of lipase in rice bran, itis difficult to directly and efficiently measure its lipase activityin the rice bran heat inactivation experiment, an experimentalmethod of adding exogenous lipase was proposed to quickly andaccurately detect the lipase activity in the heated rice bran.Taking the correlation between the temperature and time of ricebran heat treatment and the enzyme activity as the startingpoint, the self-made aluminum heating container with highsealing property was used, and the COMSOL simulationverified that the container met the uniformity requirements ofrice bran heating; Take rice bran as the heating medium, add acertain amount of exogenous plant lipase, and then heat the ricebran containing exogenous lipase, and detect the activity oflipase after heating, to explore the application of addingexogenous lipase in rice bran stabilization. The results showedthat when exogenous lipase and rice bran were mixed with 1:1(mass ratio), the lipase activity of the mixture increased in equalproportion; After heat treatment at 110 ℃, 120 ℃ and 130 ℃,the measured change of lipase activity in the mixture was in goodagreement with the change trend of rice bran lipase activity, andthe difference between different test temperature groups wassignificant (P<0.05), which provided an ideal detection model forthe detection of lipase activity in the study of rice branstabilization.
