For example :Oat is rich in β-glucan and is a healthy food with lower blood lipids and cholesterol.But its lipase content in the highest cereal [1], while linoleic acid and other unsaturated fatty acids accounted for more than 80% of oat oil, oat food in the processing and storage process is very easy to oxidize rancidity, resulting in bad smell and bitterness. Inhibition of lipase activity in oats is the key to preventing and delaying the rancidity of oatmeal.The current widely used method is steam sterilization or high temperature speculation enzyme, these methods not only time-consuming energy consumption, work and health conditions are also worse. Far infrared can be 550 ℃, 18s completely destroy the enzyme, but the high temperature easy to scorch the grain, the heating temperature is not easy to control [2].Compared with steam, infrared and other surface heat conduction heating method, microwave heating directly into the electromagnetic energy into heat, no equipment, preheating and cooling, but also eliminates the loss of heat medium, and thus relatively energy-saving, but also improve the operating conditions [3] The Microwave energy can be used mainly for the thermal effect of microwave [4], that is, under the action of microwave electromagnetic field, the polar molecules in the medium (food mainly water, salt, etc.) from the original thermal movement to follow Microwave electromagnetic field of rapid alternating and quickly arranged orientation, intense friction between molecules, microwave energy into the heat within the medium, the temperature increases.So only microwave inactivation treatment is the effect of inactivation of lipase and peroxides is the best.

Pot, the earliest refers to the bottoms of the pot when cooking burnt rice. It is called "pot coke" in Guangdong, "pot slag" in Shanxi and "pot bar" in Sichuan. In Sichuan, the folk proverb "Don't eat pot, don't turn around the kitchen table" was once...
