Problems solved by technology

[0007] In the prior art, adsorbents are usually used to adsorb and remove benzopyrene, total Sudan red, and rhodamine B. Common adsorbents include activated clay, activated carbon, or special adsorbents for firing, and adsorption resins. The characteristics of these adsorbents are often in the adsorption hazard. At the same time, some pigments will be adsorbed, and different adsorbents have different adsorption effects on different harmful substances. If similar technologies are used to directly adsorb capsanthin-related products to remove harmful substances, it will cause a large amount of capsanthin. Adsorption loss, no adsorbent that only adsorbs harmful substances but not capsanthin has not been found
For the removal of pesticide residues, at this stage, the pesticide residues in capsanthin are mainly concentrated in the light phase by molecular distillation to reduce the pesticide residues in the heavy phase, but the temperature of the molecular distillation process is high, the pigment loss is serious, and the energy consumption is high.

Embodiment 1

[0038] The present embodiment relates to the removal of harmful components in capsanthin, including the following steps:

[0039] Dissolve 1000 g of capsanthin (color value 145.2, benzopyrene 26 ppb, total Sudan red (Sudan red I-IV) 200 ppb, rhodamine B 65 ppb, ethion 36 ppm, chlorpyrifos 12 ppm, triazophos 21 ppm) into vegetable oil. Mixed solution of extraction solvent and acetone (vegetable oil extraction solvent: acetone=3:2) 10000ml, filter to remove solid insolubles, put the feed liquid into the feed tank of organic solvent-resistant nanofiltration membrane equipment, turn on the power supply, the device runs, and the separation process Keep the temperature of the feed liquid at 30-35°C, the operating pressure is 1.6-2.0MP, and the feed liquid is circulated on the upstream side of the membrane, and the primary permeate is collected downstream. When the collection volume of the primary permeate is 7L, the equipment is closed; Add 7.5L of the mixed solution of vegetable oi...

Embodiment 2

[0042] The present embodiment relates to the removal of hazardous components in capsanthin. Compared with Example 1, the difference lies in the different consumption of organic solvents, including the following steps:

[0043] Dissolve 1000g of capsanthin (color value 145.2, benzopyrene 26ppb, total Sudan red (Sudan red I-IV) 200ppb, rhodamine B65ppb, ethion 36ppm, chlorpyrifos 12ppm, triazophos 21ppm) into vegetable oil for extraction. The mixed solution of solvent and acetone (vegetable oil extraction solvent: acetone=3:2) 20000ml, filtered to remove solid insolubles, put the feed liquid into the feed tank of the organic solvent-resistant nanofiltration membrane equipment, turn on the power supply, the device is running, during the separation process Keep the temperature of the feed liquid at 30-35°C, and the operating pressure at 1.6-2.0MPa. The feed liquid is circulated on the upstream side of the membrane, and the permeate is collected downstream. When the collection volum...

Embodiment 3

[0046] Compared with Example 1, the difference is that the organic solvent is ethyl acetate.

[0047] The present embodiment relates to the removal of harmful components in capsanthin, including the following steps:

[0048] 1) Dissolve 1000 g of capsanthin (color value 145.2, benzopyrene 26 ppb, total Sudan red (Sudan red I-IV) 200 ppb, rhodamine B 65 ppb, ethion 36 ppm, chlorpyrifos 12 ppm, triazophos 21 ppm) into acetic acid. 10000ml of ethyl ester, filtered to remove solid insolubles, put the feed liquid into the feed liquid tank of the organic solvent-resistant nanofiltration membrane equipment, turn on the power supply, and run the device. During the separation process, keep the feed liquid temperature at 30-35 ℃, and the operating pressure is 1.6-2.0 MPa. The feed liquid is circulated on the upstream side of the membrane, the primary permeate is collected downstream, and the equipment is closed when the collection volume of the primary permeate is 7L; 7.5L of ethyl ace...

Abstract

The invention belongs to the field of extraction of natural products, in particular to a method for removing various harmful substances in capsanthin. The method of the invention comprises the following steps: dissolving the capsanthin to be treated in an organic solvent, and then separating the hazardous substances through an organic solvent-resistant nanofiltration membrane; the organic solvent is acetone, vegetable oil extraction solvent or ethyl acetate one or more of them. The method of the invention has the advantages of simple process, high capsanthin yield, and a loss rate of less than 0.5% compared with the non-removal process. The method of the invention can remove a number of harmful components at the same time, including removing benzopyrene in capsanthin, and reducing the level of tens of ppb to <10 ppb; removing illegal dyes such as Sudan red and rhodamine B, from tens to several 100 ppb is removed to less than 10 ppb; pesticide residues are removed from tens of ppm to less than 20 ppb, meeting the quality requirements of high-end products, and the safety is greatly improved.

Description

technical field [0001] The invention belongs to the field of extraction of natural products, in particular to a method for removing various harmful substances in capsanthin. Background technique [0002] Capsanthin is an oily liquid obtained from red pepper through extraction technology, which is rich in natural carotenoids such as capsanthin and capsanthin, which exist in the form of esters with fatty acids. Therefore, capsanthin is an excellent fat-soluble pigment, which is widely used in food, daily chemical and medical coloring. [0003] Benzoapyrene, chemical formula: C 20 H 12 , which means BaP in English, is a kind of pentacyclic polycyclic aromatic hydrocarbons. Crystallized as a yellow solid, this substance is produced under incomplete combustion between 300 and 600°C. Benzopyrene is found in coal tar, which can be found in car exhaust, smoke from tobacco and wood burning, and charcoal-grilled foods. Benzopyrene, a mutagen and carcinogen, has been implicated in...
