Embodiment 1
[0022] In this example, 1 kg of Artemisia annua seeds was used as a raw material, and the Artemisia artemisiae latex emulsifier was produced through three steps of hot lye extraction, neutralization and desalination, and spray drying. The specific process is as follows:
[0023] (1) hot water extraction
[0024] Soak 1 kg of Artemisia annua seeds in 20 kg of NaOH solution with a concentration of 0.5 mol / L, extract at 70°C for 2 hours, and keep stirring, separate the extract, let it stand for 1 hour, and separate layers.
[0025] (2) Neutralization and desalination
[0026] Take the supernatant and adjust it to neutral with HCl solution with a concentration of 1mol / L, and then carry out continuous ultrafiltration and concentration treatment on the neutralized solution. 80°C, remove excess salt, and obtain a high-concentration artemisia gum solution.
[0027] (3) spray drying
[0028] The Artemisia gum solution in step (2) is spray-dried, the air inlet temperature is 200°C, a...
Embodiment 2
[0030] In this example, 1 kg of Artemisia annua seeds was used as a raw material, and the Artemisia artemisiae latex emulsifier was produced through three steps of hot lye extraction, neutralization and desalination, and spray drying. The specific process is as follows:
[0031] (1) hot water extraction
[0032] Soak 1 kg of Artemisia annua seeds in 18 kg of NaOH solution with a concentration of 0.5 mol / L, extract at 60°C for 4 hours, and keep stirring, separate the extract, let it stand for 1.5 hours, and separate layers.
[0033] (2) Neutralization and desalination
[0034] Take the supernatant and adjust it to neutral with HCl solution with a concentration of 1mol / L, and then carry out continuous ultrafiltration and concentration treatment on the neutralized solution. At 70°C, remove the salt in the concentrated solution to obtain a high-concentration Artemisia gum solution.
[0035] (3) spray drying
[0036] The Artemisia gum solution in step (2) is spray-dried, the air...
Embodiment 3
[0038] In this example, 1 kg of Artemisia annua seeds was used as a raw material, and the Artemisia artemisiae latex emulsifier was produced through three steps of hot lye extraction, neutralization and desalination, and spray drying. The specific process is as follows:
[0039] (1) hot water extraction
[0040] Soak 1 kg of Artemisia annua seeds in 25 kg of NaOH solution with a concentration of 0.5 mol / L, extract at 80°C for 2 hours, and keep stirring, separate the extract, let it stand for 1.5 hours, and separate layers.
[0041] (2) Neutralization and desalination
[0042] Take the supernatant and adjust it to neutral with a HCl solution with a concentration of 1mol / L, and carry out continuous ultrafiltration and concentration treatment on the neutralized solution. 90°C, remove excess salt, and obtain a high-concentration artemisia gum solution.
[0043] (3) spray drying
[0044] The Artemisia gum solution in step (2) is spray-dried, the air inlet temperature is 190°C, a...
