Abstract: Corn pollen is rich in nutrients and nutrients in non-wall-breaking pollen can not be well digested by human body. Corn pollen was carried out wall-breaking treatments by four methods such as the temperature difference method, the ultrasonic method, the enzyme method and the synthesis method. The orthogonal design L9(33) was applied in experiments. The results showed that the optimum formula was 1:5 of pollen and water, 90℃ of temperature difference, for one hour in the temperaturedifference method. The optimum formula of the enzyme method was 2% of pollen in water, 55℃ of bathing temperature, for 12 hours. The procedure of synthesis method was that the temperature difference method was used to break pollen wall, then the ultrasonic method and the enzyme method. The results exhibited that the wall-breaking ratio of temperature difference method was 46.3%, the ultrasonic methods’ was 31.2%, the enzyme methods’ was 80.4% and the synthesis methods’ was 98.6%. The wall-breaking ratios of the enzyme method and the synthesis method were very significantly higher than temperature difference method and ultrasonic method. The synthesis method had the highest wall-breaking ratio with favorable utilization.
