Embodiment 1
[0056] Embodiment 1 raw material preparation
[0057] 1. Preparation of calcium fruit fiber:
[0058] The preparation method of the calcium fruit fiber comprises the following steps: uniformly mixing fresh calcium fruit stems, calcium fruit leaves and waste sawdust at a mass ratio of 7:4:1.5, placing them in an ultrasonic cleaning machine at 200W and 30KHz for cleaning for 4 minutes, draining Drying, crushing, adding water with 1 times the amount of the crushed material, ultrasonic extraction at room temperature 300W, 40KHz for 12min, and then performing high-voltage pulse electric field treatment for 12min under the conditions of electric field strength 30kV / cm, pulse time 500μs, and pulse frequency 300Hz; adjust the pH value 8. Add biological enzyme with 0.2% mass of the mixture, and enzymatically hydrolyze at 55°C for 12 minutes; the enzymolyzed solution is concentrated under reduced pressure to a solid content of 50%, and placed in a microwave dryer at 2000W and 140°C for ...
