Problems solved by technology

[0007] CN201010227935.5 provides a method for decolorizing DHA grease at room temperature by using compound packing column chromatography technology, which reduces the temperature and time of the subsequent deodorization process and reduces the formation of trans acid, but does not illustrate with specific data. The used There are many kinds of adsorbents, and they have to go through a relatively complicated pretreatment process, and in the technical solution of the invention, DHA is a solvent system for column chromatography, and subsequent products need to be desolvated, so it is difficult to realize industrial production
[0008] CN200980139300.5 provides a column chromatography technology with a single column or multiple columns connected in series to purify crude triglycerides, but the product of this invention involves a precipitation process, and it is difficult to achieve industrialization

Embodiment 1

[0061] Use silica gel and activated carbon at a ratio of 1:1, mix well as an adsorbent, dry-load it into a chromatography column, and use a metering pump to inject decolorized soybean oil into the chromatography column at a flow rate of 150mL / min. And the pipeline pressure is 10-20 bar, the chromatographic column pressure is 20-30 bar, and the oil sample is collected to obtain the prepared oil sample. The chromatographic process does not need to fill with nitrogen or oxygen, and does not need to be heated in a water bath. In the following examples and comparative examples, except for the injection of solid fats such as decolorized palm oil, the operation process is the same.

Embodiment 2

[0063] Use silica gel and activated carbon at a ratio of 4:1, mix well as an adsorbent, dry-load it into a chromatographic column, use a metering pump to inject decolorized soybean oil into the chromatographic column at a flow rate of 150mL / min, and collect oil samples. The prepared oil sample was obtained.

Embodiment 3

[0065] Use silica gel and activated carbon at a ratio of 1:4, mix well as an adsorbent, dry-load it into a chromatographic column, use a metering pump to inject decolorized soybean oil into the chromatographic column at a flow rate of 150mL / min, and collect oil samples. The prepared oil sample was obtained.

Abstract

The invention provides a method for reducing trans fatty acids, 3-chloro-1,2-propylene glycol and esters of 3-chloro-1,2-propylene glycol, and / or glycidol and glycidol esters and a grease refining method; the methods include the step of carrying out column chromatography of decolorized grease and the step of optionally carrying out deodorization in the temperature range of 60-150 DEG C after column chromatography. The methods reduce the production energy consumption, satisfy product indexes, meet and even are more superior to edible performance indexes of grease prepared by a conventional processing method, besides, can avoid formation of a series of side products brought by high temperature deodorization, and improve the edible grease quality and edible safety.

Description

technical field [0001] The invention belongs to the technical field of oil refining, and in particular relates to a method for reducing trans fatty acids by using column chromatography instead of the high-temperature deodorization process of oil. Background technique [0002] As a necessity in the daily diet, edible oil has attracted widespread attention. It not only provides energy for the human body, but also brings a large amount of essential fatty acids, and also introduces some natural antioxidants such as vitamin E, phytosterols and other nutrients. With the rapid development of the economy and the improvement of people's living standards, the consumption of oil has increased significantly, and people have gradually shifted their attention to the quality of oil. At present, the pursuit of healthy, nutritious and safe edible oils has become the urgent hope of consumers, and providing a high-quality oil has become an inevitable trend in the development of the oil industr...
