Problems solved by technology

However, the processing technology of this kind of deep-sea fish oil is relatively complicated, not only the production process consumes high energy and pollutes, but also the yield is low
This determines that the price of deep-sea fish oil currently on the market is relatively expensive, and it is not suitable for public consumption

Embodiment 1

[0028] (1) Pass the degummed and decolorized deep-sea fish oil (commercially available) through a wiped-film molecular distillation column with a vacuum of 0.01Pa and a temperature of 80°C. The retention time of the degummed and decolorized deep-sea fish oil in the wiped-film molecular distillation column is 5s , that is, deep-sea fish oil without fishy smell.

[0029] (2) Detection:

[0030] A. DHA and EPA content: use GC-MS to detect the DHA and EPA content in deep-sea fish oil, and the test results are as follows: Figure 1~2 As shown in Tables 1-2, it can be seen that the contents of DHA and EPA in the deep-sea fish oil after passing through the column are basically the same as those in the deep-sea fish oil before passing through the column.

Embodiment 2

[0042] (1) Pass the degummed and decolorized deep-sea fish oil (commercially available) through a wiped-film molecular distillation column with a vacuum degree of 10Pa and a temperature of 180°C. The retention time of the degummed and decolorized deep-sea fish oil in the wiped-film molecular distillation column is 10s. That is, deep-sea fish oil without fishy smell is obtained.

[0043] (2) Detection:

[0044] A. DHA and EPA content: use gas chromatography-mass chromatography to detect the DHA and EPA content in the deep-sea fish oil. Through the detection, we can know the DHA and EPA content in the deep-sea fish oil after passing the column and the DHA and EPA content in the deep-sea fish oil before passing the column. basically the same.

[0047] (1) The degummed and decolorized deep-sea fish oil (commercially available) is passed through a wiped-film molecular distillation column with a vacuum degree of 30Pa and a temperature of 200°C. The retention time of the degummed and decolorized deep-sea fish oil in the wiped-film molecular distillation column is 15s. That is, deep-sea fish oil without fishy smell can be obtained.

[0048] (2) Detection:

[0049] A. DHA and EPA content: Use GC-MS to detect the DHA and EPA content in the deep-sea fish oil. Through the detection, it can be known that the DHA and EPA content in the deep-sea fish oil after the column is higher than the DHA and EPA in the deep-sea fish oil before the column. The content decreases by mass percentage 0.24% and 0.15%.

Abstract

The invention discloses stink-free deep sea fish oil and a preparation method and application thereof. The preparation method comprises the following step of: making degumed and discolored deep sea fish oil pass through a molecular distillation column with the vacuum degree of 0.01 to 30 Pa and the temperature of between 80 and 200 DEG C so as to obtain the stink-free deep sea fish oil. The preparation method has the advantages of low damage to the deep sea fish oil and good deodorization effect. The obtained deep sea fish oil has no stink substantially and can be used for table oil for direct eating or seasoning. Compared with high-temperature steam deodorization, the preparation method has the advantages of low cost, better deodorization effect, and contribution to market popularization. The stink-free deep sea fish oil is compounded with an antioxidant to prepare the stable stink-free deep sea fish oil with the storage period of half a year and invariable unsaturated fatty acid content.

Description

technical field [0001] The invention relates to the preparation of fats and oils, in particular to a deep-sea fish oil without fishy smell and its preparation method and application. Background technique [0002] EPA and DHA belong to the omega-3 series of polyunsaturated fatty acids, which are essential fatty acids for the human body. EPA (eicosapentaenoic acid) is known as "the scavenger of human blood vessels", which can effectively reduce the content of cholesterol and triglycerides, prevent blood vessel coagulation, reduce blood viscosity, prevent cerebral hemorrhage, cerebral thrombosis and other diseases, and reduce arteriosclerosis And high blood pressure, promote blood circulation and eliminate fatigue, reduce fat formation, eliminate dark spots, improve skin nutrition, prevent brain cell aging, help memory and other effects. DHA (docosahexaenoic acid), commonly known as "brain gold", is an important component of the human brain, eyes, nervous system and defense sy...
