Embodiment 1
[0035] 1) Picking and cleaning: picking fresh young fig leaves, and washing away impurities on the surface with flowing water;
[0036] 2) Soaking in hot lye: Prepare a soda ash aqueous solution with a concentration of 15wt%, heat it to 85°C, and soak the cleaned fig leaves in it for 45 minutes. During the soaking process, it is accompanied by ultrasonic oscillation. The frequency of the ultrasonic wave is 15-20KHz, and the soaking is completed Finally, remove the fig leaves and let them dry naturally;
[0037] 3) cutting: cutting the fig leaves obtained in step 2), and cutting one leaf evenly into 3 to 5 pieces;
[0038] 4) One-time greening: place the fig leaf obtained in step 3) under far-infrared rays for irradiation, the wavelength of far-infrared rays is 2-14 μm, the temperature of irradiation is 155° C., and the irradiation time is 2.5 minutes;
[0039] 5) Kneading: put the fig leaves after step 4) once greening into the kneading machine while they are hot, and knead t...
Embodiment 2
[0045] 1) Picking and cleaning: picking fresh young fig leaves, and washing away impurities on the surface with flowing water;
[0046] 2) Soaking in hot lye: Prepare a soda ash aqueous solution with a concentration of 10wt%, heat it to 80°C, and soak the cleaned fig leaves in it for 60 minutes. The soaking process is accompanied by ultrasonic oscillation. The frequency of the ultrasonic wave is 15-20KHz, and the soaking is completed. Finally, remove the fig leaves and let them dry naturally;
[0047] 3) cutting: cutting the fig leaves obtained in step 2), and cutting one leaf evenly into 3 to 5 pieces;
[0048] 4) One-time greening: irradiating the fig leaves obtained in step 3) under far-infrared rays, the wavelength of far-infrared rays is 2-14 μm, the irradiation temperature is 150° C., and the irradiation time is 3 minutes;
[0049] 5) Kneading: put the fig leaves after step 4) once greening into the kneading machine while they are hot, and knead the thin fig leaves into...
