Embodiment 1
[0024] Take a certain quality of indica rice, grind it through a pulverizer and pass through a 60-mesh sieve to get indica rice flour; add the prepared indica rice flour and purified water into an enzymolysis tank at a mass ratio of 1:2, and mix evenly; Add alkaline protease (200,000 U / g) at a ratio of 0.03% by mass, and perform enzymatic hydrolysis at 50°C for 1 hour, and control the pH value to 8.0 during the enzymolysis process; add neutral protease (50,000 U / g) at a ratio of 0.02% by mass of indica rice flour U / g), hydrolyze at 45°C for 2 hours, and control the pH value to 6.5 during the enzymolysis; add trypsin (4000 U / g) according to the proportion of 0.04% of the mass of indica rice flour, and enzymatically digest at 35°C Decompose for 3 hours, control the pH value to 7.5 during the enzymolysis process, and obtain the enzymolysis feed liquid; heat the obtained enzymolysis feed liquid to 80°C to inactivate the enzyme; send the obtained enzymolysis feed liquid into the twi...
Embodiment 2
[0027] Take a certain quality of indica rice, pass it through a 70-mesh sieve after being pulverized by a pulverizer, and then get indica rice flour; add the prepared indica rice flour and purified water into an enzymolysis tank at a mass ratio of 1:3, and mix evenly; Alkaline protease (200000 U / g) was added at a ratio of 0.08% by mass, and the enzymatic hydrolysis was carried out at 55°C for 2 hours. U / g), hydrolyze at 48°C for 3 hours, and control the pH value to 7.0 during the enzymolysis; add trypsin (4000 U / g) according to the proportion of 0.09% of the mass of indica rice flour, and enzymolyze at 37°C Decompose for 4 hours, control the pH value to 8.0 during the enzymolysis process, and obtain the enzymolysis feed liquid; heat the obtained enzymolysis feed liquid to 82°C to inactivate the enzyme; send the obtained enzymolysis feed liquid into the twin-screw extruder through the conveying pipeline The extruder is used for extruding and puffing. The temperature of extrusio...
