Problems solved by technology

This treatment method is an improvement on the current process, and overcomes the shortcomings of the high anisidine value and high absorbance of the medicinal oil prepared in the current process. Specifically, it refers to contacting the mixed adsorbent with the raw material oil, The resulting oil has an extremely low anisidine value and lower light absorption value, especially a substantial reduction in the anisidine value, which can improve the drug safety of the human body, especially in line with the stringent US pharmaceutical standards

preparation example Construction

[0106] Before the preparation method described in the present invention, the above-mentioned pretreatment steps may not be included, because the refining steps described in the present invention can also effectively remove by-products such as free fatty acids, peroxides, unsaponifiables, metal ions, arsenic salts, etc. product or impurity. Therefore, it is only necessary to carry out the refining treatment steps of various raw oils and fats, and the obtained oils can meet various requirements of medicinal oils, or achieve the purpose of effectively reducing the content of chloropropanol esters.

[0107] The oil preparation method disclosed in the present invention includes the above-mentioned refining treatment.

[0108] Post-processing

[0109] The post-treatment described in the present invention includes desolvation and other conventional post-treatments.

[0110] Precipitation refers to the solvent removal of the product in the product, which is a routine method for thos...

Embodiment 12-17

[0197] In Examples 12-17, according to the following operations, the raw materials are mixed uniformly as fillers, and the following operations are carried out:

[0198] 1. The results of blank 1 and blank 2 are shown in Table 4 according to the oil used for frying without using adsorbent;

[0199] 2. Weigh 5-10 parts of 60-400 mesh silica gel, 5-10 parts of clay, 5-8 parts of activated carbon, and 4-8 parts of magnesium silicate, mix them evenly, and pack them in a glass chromatography column;

[0200] 3. Take 10 parts of oil used for frying, mix well with n-hexane as solvent, slowly add to the top of the chromatography column, elute with n-hexane, and protect the whole process with nitrogen; the elution process is controlled at 24°C to 60°C between.

[0201] 3. The eluent is removed from n-hexane with a rotary evaporator at 40°C to obtain grease with low chloropropanol ester content. The details of Examples 12-17 are shown in Table 4.

Abstract

The invention provides a mixed adsorbent, comprising one or more of a silica gel, carclazyte, silicate and activated carbon. The mixed adsorbent can be used for preparing the grease with an extremely low anisidine value and absorbance value. The invention also provides a method for removing chloropropanol ester substances from the grease. The method comprises a step of contacting to-be-treated grease with the above mixed adsorbent. The content of 3-MCPD ester in the obtained grease product is below 0.8 ppm; and the content of 2-MCPD ester is below 0.5 ppm.

Description

[0001] The present invention requires the patent application number CN201310004485.7, the application date is January 7, 2013, and the invention title is a Chinese patent application priority of a mixed adsorbent, medicinal oil and its preparation method. technical field [0002] The invention relates to the field of oil preparation, in particular to a mixed adsorbent and its application in preparing medicinal oil and removing chloropropanol esters in oil. Background technique [0003] Oil for injection is usually a colorless clear liquid, odorless or almost odorless, light in taste, slightly soluble in ethanol, mixed freely with ether, chloroform or petroleum ether, and almost insoluble in water. As an energy supplement and pharmaceutical excipient, it can be used as a solvent for preparing fat emulsion and fat-soluble drugs. Fat emulsion infusion is a concentrated high-energy parenteral rehydration solution, which can be used for intravenous injection and can be completely...
