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 pr

Embodiment 1

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

[0039] Dissolve capsanthin 1000g (color value 145.2, benzopyrene 26ppb, total Sudan red (Sudan Ⅰ-Ⅳ) 200ppb, rhodamine B 65ppb, ethion 36ppm, chlorpyrifos 12ppm, triazophos 21ppm) into vegetable oil pumping 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 liquid tank of the organic solvent-resistant nanofiltration membrane equipment, turn on the power, the device is running, and the separation process Keep the temperature of the feed liquid at 30-35°C, and the operating pressure is 1.6-2.0MP. The feed liquid circulates 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 a mixed solution of vegetable oi...

Embodiment 2

[0042] This embodiment relates to the removal of harmful components in capsanthin. Compared with Example 1, the difference is that the amount of organic solvent is different, including the following steps:

[0043] Dissolve capsanthin 1000g (color value 145.2, benzopyrene 26ppb, total Sudan red (Sudan Ⅰ-Ⅳ) 200ppb, rhodamine B 65ppb, ethion 36ppm, chlorpyrifos 12ppm, triazophos 21ppm) into vegetable oil for extraction Mixed solution of solvent and acetone (vegetable oil extraction solvent: acetone = 3:2) 20000ml, filter to remove solid insoluble matter, put the feed liquid into the feed liquid tank of the organic solvent-resistant nanofiltration membrane equipment, turn on the power, the device is running, and 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 circulates on the upstream side of the membrane, and the primary permeate is collected downstream. When the collection volume of the primary...

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, comprising the following steps:

[0048] 1) Dissolve capsanthin 1000g (color value 145.2, benzopyrene 26ppb, total Sudan red (Sudan Ⅰ-Ⅳ) 200ppb, rhodamine B 65ppb, ethion 36ppm, chlorpyrifos 12ppm, triazophos 21ppm) into acetic acid Ethyl ester 10000ml, filter to remove solid insoluble matter, put the feed liquid into the feed liquid tank of the organic solvent-resistant nanofiltration membrane equipment, turn on the power, the device runs, keep the feed liquid temperature at 30-35 °C during the separation process, and the operating pressure is 1.6-2.0 MPa. 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 turned off; 7.5L of ethyl acetate is added to th...

Abstract

The invention belongs to the field of extraction of natural products, and particularly relates to a method for removing various hazardous substances in capsorubin. The method comprises the following steps: dissolving capsorubin to be treated in an organic solvent, and separating hazardous substances through an organic solvent-resistant nanofiltration membrane, wherein the organic solvent is one or more selected from acetone, a vegetable oil extraction solvent and ethyl acetate. The method disclosed by the invention is simple in process and high in capsorubin yield, and a loss rate in the invention does not exceed 0.5% compared with a loss rate of a non-removal process. According to the method disclosed by the invention, multiple harmful components including benzopyrenes in capsorubin can be removed at the same time, and the content of benzopyrenes in capsorubin is reduced from dozens of ppb to less than 10 ppb; the concentrations of illegal dyes such as Sudan red and rhodamine B are decreased from dozens of to hundreds of ppb to 10 ppb or below; the concentrations of pesticide residues are decreased from dozens of ppm to 20 ppb or below; and thus, the quality requirement on high-end products is met, and safety is greatly improved.

Description

technical field [0001] The invention belongs to the field of extraction of natural products, and in particular relates to a method for removing various harmful substances in capsanthin. Background technique [0002] Capsanthin is an oily liquid obtained from red peppers through extraction technology. It is rich in natural carotenoids such as capsanthin and capsanthin. These natural carotenoids 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 (Benzoapyrene), chemical formula: C 20 h 12 , which means BaP in English, is a five-ring polycyclic aromatic hydrocarbon. 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 vehicle exhaust, tobacco and wood smoke, and char-grilled foods. Benzopyrene, a mutagen and carcinogen, h...
