Embodiment 1
[0044] Crush and temper the cinnamon:
[0045] Grind the cinnamon, pass through a 40-mesh sieve, evenly moisten it with 5% NaCl aqueous solution (concentration: 2%) accounting for the mass of the raw material, stir evenly, and then seal it and let it stand for 2 hours to complete conditioning to obtain conditioned cinnamon powder.
[0046] Freezing and thawing ground cinnamon:
[0047] Put the conditioned cinnamon powder into a freezer at -10°C for 9 hours, take it out, and thaw it quickly with microwave radiation for 10 minutes in a microwave device to obtain the thawed cinnamon powder.
[0048] Low-temperature extraction of cinnamon powder:
[0049] Put the thawed cinnamon powder into a 150-mesh net bag and tie the mouth, put it into a 1.3MPa pressure-resistant extraction tank with a cover that can be sealed, vacuumize the extraction tank, and then inject butane into it. The ratio of solvent to material is 7:1 (V / m); adjust the temperature of the extraction tank to 30°C, a...
Embodiment 2
[0053] Crush and temper the cinnamon:
[0054] Cinnamon is pulverized, crosses 60 mesh sieves, uses the NaHCO that accounts for 15% of raw material quality 3 The aqueous solution (with a concentration of 10%) is evenly moistened, stirred evenly, and then sealed and left to stand for 5 hours to complete the tempering to obtain the tempered cinnamon powder.
[0055] Freezing and thawing ground cinnamon:
[0056] Put the tempered cinnamon powder into a freezer at -15°C for 8 hours, take it out, and thaw it quickly with microwave radiation for 5 minutes in a microwave device to obtain the thawed cinnamon powder.
[0057] Low-temperature extraction of cinnamon powder:
[0058] Put the thawed cinnamon powder into a 200-mesh net bag and tie the mouth, put it into a 1.3MPa pressure-resistant extraction tank with a cover that can be sealed, vacuumize the extraction tank, and then inject butane into it. The ratio of solvent to material is 10:1 (V / m); adjust the temperature of the ext...
Embodiment 3
[0062] Crush and temper the cinnamon:
[0063] Cinnamon is crushed, passed through an 80 mesh sieve, and mixed with NaCl and NaHCO which account for 15% of the mass of the raw material 3 (Mixed mass ratio 1:2) aqueous solution (concentration: 12%) is uniformly moistened, stirred evenly, sealed and allowed to stand for 8 hours to complete the tempering, and the tempered cinnamon powder was obtained.
[0064] Freezing and thawing ground cinnamon:
[0065] Put the tempered cinnamon powder into a freezer at -20°C for 5 hours, take it out, and thaw it quickly with microwave radiation for 20 minutes in a microwave device to obtain the thawed cinnamon powder.
[0066] Low-temperature extraction of cinnamon powder:
[0067]Put the thawed cinnamon powder into a 300-mesh net bag and tie the mouth, put it into a sealable pressure-resistant 1.3MPa extraction tank with a cover, vacuumize the extraction tank, and then inject propane into it. The ratio of solvent to material is 5:1 (V / m);...
