Example Embodiment

[0021] Example 1

[0022] In this example, 1kg of Artemisia sphaerocephala seeds was used as raw material, and the Artemisia sphaerocarpa gum emulsifier was prepared through three steps of hot lye extraction, neutralization and desalination, and spray drying. The specific process is:

[0023] (1) Hot water extraction

[0024] Soak 1 kg of Artemisia sphaerocephala seeds in 20 kg of NaOH solution with a concentration of 0.5 mol / L, and extract for 2 h at 70° C. with constant stirring, separate the extract, and let stand for 1 h to separate into layers.

[0025] (2) Neutralization and desalination

[0026] Take the supernatant and adjust it to neutral with a concentration of 1mol / L HCl solution, and carry out continuous ultrafiltration and concentration treatment on the neutralized liquid. The molecular weight cut-off of the filter membrane is 20000~30000Da, the control pressure is 0.5MPa, and the temperature is At 80°C, remove excess salt to obtain a high-concentration solution of Artemis...

[0029] Example 2

[0030] In this example, 1kg of Artemisia sphaerocephala seeds was used as raw material, and the Artemisia sphaerocarpa gum emulsifier was prepared through three steps of hot lye extraction, neutralization and desalination, and spray drying. The specific process is:

[0031] (1) Hot water extraction

[0032] 1kg of Artemisia sphaerocephala seeds were immersed in 18kg of 0.5mol / L NaOH solution, extracted at 60°C for 4h, and continuously stirred to separate the extract, stand for 1.5h, and layer.

[0033] (2) Neutralization and desalination

[0034] Take the supernatant and adjust it to neutral with a concentration of 1mol / L HCl solution, and carry out continuous ultrafiltration and concentration treatment on the neutralization solution. The molecular weight cut-off of the filter membrane is 10000~30000Da, the control pressure is 0.3MPa, and the temperature is At 70°C, remove the salt in the concentrated solution to obtain a high-concentration solution of Artemisia Gum....

[0037] Example 3

[0038] In this example, 1kg of Artemisia sphaerocephala seeds was used as raw material, and the Artemisia sphaerocarpa gum emulsifier was prepared through three steps of hot lye extraction, neutralization and desalination, and spray drying. The specific process is:

[0039] (1) Hot water extraction

[0040] 1 kg of Artemisia sphaerocephala seeds were immersed in 25 kg of NaOH solution with a concentration of 0.5 mol / L, and extracted at 80° C. for 2 hours with constant stirring. The extract was separated and stood for 1.5 hours to separate layers.

[0041] (2) Neutralization and desalination

[0042] Take the supernatant liquid and adjust it to neutral with a concentration of 1mol / L HCl solution, and carry out continuous ultrafiltration and concentration treatment on the neutralized liquid. The molecular weight cut-off of the filter membrane is 10000~25000Da, the control pressure is 0.8MPa, and the temperature is Remove excess salt at 90°C to obtain a high-concentrati...

Abstract

The invention relates to a processing method of a modified Artemisia sphaerocephala Krasch gum emulsifier and belongs to the technical field of food additive production. The modified Artemisia sphaerocephala Krasch gum emulsifier is prepared through hot alkali liquid extraction, HCl neutralization, ultrafiltration concentration and spray drying and has good emulsification effects and stable emulsibility. The processing method has a high Artemisia sphaerocephala Krasch gum extraction rate, realizes a low cost, produces less waste liquid and is suitable for industrial production.

Description

technical field [0001] The invention relates to a processing method of a food additive, in particular to a preparation method of an artemisia latex emulsifier. Background technique [0002] Artemisia gum is a natural non-polluting plant polysaccharide extracted from Artemisia annua seeds. It has the characteristics of high nutrient content, high viscosity, strong water absorption, and good emulsification effect. It can replace pectin, agar gum, and Arabica in the food industry. Glue, etc. are used as thickeners, adhesives, stabilizers, and are excellent green food additives. [0003] At present, in the production of Artemisia gum, most of them use the method of water-soluble alcohol precipitation to produce Artemisia gum. However, due to the influence of factors such as raw material origin and extraction conditions, the yield of Artemisia gum is low, the emulsification is unstable, and the water consumption is large. , the extraction cost is high. Contents of the inventio...
