Taking soybean protein powder and alkaline 2709 protease as raw materials,the effect of ultrasonic power on hydrolysis degree (DH) of soybean protein were studied,and orthogonal experiments with and without ultrasound were also done to optimize the technological parameters.The results indicated that the efficiency of ultrasound depended on its power.Compared with those without ultrasound,the ultrasound of 40 kHz and 128 W increased the DH by 6.48%~30.86%,and the average of DH increment was 21.18%.So it enhanced the enzymatic hydrolysis of soybean protein(EHSP) effectively.The optimal technological parameters of EHSP with or without ultrasound were the same,i.e.,temperature 55 ℃,pH=10.5,substrate mass concentration ρ(substrate)=5 g/L and enzyme dosage w(enzyme)=5%.Although ultrasound did not change the parameters,it changed the order of factors influencing the DH.The order with ultrasound was:enzyme mass fraction>pH> substrate mass concentration>temperature,and without ultrasound was:enzyme mass fraction>temperature>substrate mass concentration>pH.

Casein phosphopeptides(CPPs) were continuously prepared by coupling of enzymatic hydrolysis and membrane separation.In order to prepare target active peptides with high purity and good yield,operating stability of trypsin and membrane rejection of casein were studied respectively.The influences of operating parameters,including substrate mass concentration,enzyme mass concentration,reaction volume and permeation flux,on the reaction conversion and reactor capacity were investigated.The continuous hydrolysis system was also analyzed by high performance size exclusion chromatography(HPSEC) and a mathematical model was established to describe the relationship between reaction conversion and modified space-time.The characteristic of hydrolysis process in a CSTR/UF was compared with BSTR.The results show that taking advantage of the integrated reaction-separation technique,the productivity or utilization efficiency of enzyme can be increased greatly,and the product is purified simultaneously.Therefore,enzymatic membrane reactor provided a more efficient way to prepare active peptides.

In order to study the behaviors of extrusion conversion of amylase,a high-temperature resistant α-amylase as catalyzer and a twin-screw extruder were used for testing the gelatinization and liquefaction of corn starch,and extrudates with different dextrose equivalent(DE value is 17~36) were obtained.The response surface methodology was used to study the influences of screw speed,barrel temperature,material moisture and enzyme mass fraction on DE values.The result showed that DE values were not effected by screw speed,but increased with material moisture,enzyme mass fraction and barrel temperature;when the temperature in the barrel was 95℃,DE value was maximum and reduced with the increase of temperature.
