Embodiment 1
[0020] Embodiment 1: a kind of method that improves the utilization rate of starch in corn husk, is raw material with the corn husk that obtains after washing and separating through high-pressure curved sieve in the corn deep processing process, and steps are as follows:
[0021] (1) Add corn husks to water at a ratio of 1:10, and at a temperature of 25° C., use a power of 5 kW for ultrasonic treatment for 20 minutes to obtain corn husk slurry;
[0022] (2) Adjust the pH value of the corn husk slurry prepared in step (1) to 5.5 with sodium carbonate, and then add a medium-temperature amylase for enzymatic hydrolysis. The action conditions of the medium-temperature amylase are: time 15min, temperature 65°C, enzyme concentration in the system 0.02ml / L, substrate concentration: 100g / L, to obtain enzymatic hydrolyzate of corn hulls;
[0023] (3) separating the corn bran and the feed liquid in the corn bran enzymatic hydrolysis solution prepared in step (2). The moisture content o...
Embodiment 2
[0024] Embodiment 2: a kind of method that improves the utilization rate of starch in the corn bran, is raw material with the corn bran that obtains after washing and separating through the high-pressure curved sieve in the deep processing of corn, and the steps are as follows:
[0025] (1) Add corn husks into water at a ratio of 1:8, and at a temperature of 30° C., use a power of 7 kW for ultrasonic treatment for 15 minutes to obtain corn husk slurry;
[0026] (2) Adjust the pH value of the corn husk slurry prepared in step (1) to 6.5 with sodium hydroxide, and then add mid-temperature amylase for enzymatic hydrolysis. The action conditions of the mid-temperature amylase are: time 20min, temperature 70°C, The concentration is 0.03ml / L, the substrate concentration is: 120g / L, and the enzymatic hydrolyzate of corn hulls is obtained;
[0027] (3) the corn bran in the corn bran enzymatic hydrolysis solution that step (2) is made is separated from feed liquid; The moisture of corn...
Embodiment 3
[0028] Embodiment 3: a kind of method that improves the utilization rate of starch in corn husk, is raw material with the corn husk that obtains after washing and separating through high-pressure curved sieve in the corn deep processing process, and steps are as follows:
[0029] (1) Add corn husks into water at a ratio of 1:6, and at a temperature of 35° C., use a power of 9 kW for ultrasonic treatment for 11 minutes to obtain corn husk slurry;
[0030] (2) Adjust the pH value of the corn husk slurry prepared in step (1) to 7.0 with sodium carbonate, and then add a medium-temperature amylase for enzymatic hydrolysis. The conditions for the action of the medium-temperature amylase are: time 25min, temperature 75°C, and enzyme concentration in the system 0.05ml / L, and substrate concentration: 150g / L, to obtain enzymatic hydrolyzate of corn hulls;
[0031] (3) the corn bran in the corn bran enzymatic hydrolysis liquid that step (2) is made is separated from feed liquid; The mois...
