Study about the Effects of Superheated Steam on Lipase Inactivation and Storage Quality of Oat

SHANG Yang;XIONG Tianyu;LI Zaigui;College of Food Science and Nutritional Engineering,China Agricultural University;  
Oat groats are treated with superheated steam to inactivate the lipase and to improve its storage properties. The effect of lipase deactivated with superheated steam is studied by changing the tempering condition, the superheated steam temperature, flow rate and time. The changes of storage characters of the inactivated oat flour are assessed by accelerated storage test. The results show that the oat can be inactivated efficiently and completely by control the condition as follows:more than 20% moisture content,the temperature of superheated steam should be more than 165 ℃, the steam flow rate should above 10.0 m3/h,processing time should not less than 80 s. Six varieties of oats are inactivated and storage under the condition with 40 ℃ and 80% moisture content to process the accelerated storage test. According to the study,the increase in the FFA significantly reduced after the complete inactivation which can maintain the quality stability of oat flour.
