摘要
采用差热扫描量热法(DSC)研究了不同压力及保压时间对玉米淀粉糊化度的影响。在700MPa压力下,保压2min即可使86.8%玉米淀粉糊化,达到一般食品加工要求;保压5min,可使玉米淀粉100%糊化。
The effect of high pressure on gelatinization degree of maize starch was studied with the differential heating scanning calorimeter(DSC). The maize starch was gelatinized 86.8 % under pressure of 700 MPa for 2 min. It can accord with the demands of ordinary foods. Under this pressure and holding for 5 min., all of the maize starch will be gelatinized (the gelatinization degree is 100 %). This is one of the advantages of the high pressure for food process.
