Problems solved by technology

However, pre-treatment methods such as freezing and thawing and enzymatic extraction process take a long time, and the temperature required for enzymatic hydrolysis is high. Fish oil is easily oxidized
The extraction effect mainly depends on the enzyme, and the parameter control is more cumbersome

Embodiment 1

[0021] At 10°C, take 10kg of washed abalone viscera, add 0°C distilled water at a material-to-liquid ratio of 1:1, beat, and pass through a 40-mesh sieve to prepare a pretreatment solution at about 5°C. The pretreatment solution was treated by a high-voltage pulsed electric field with an electric field intensity of 15kV / cm, a frequency of 3170Hz, a pulse width of 1.5μs, and a treatment time of 1500μs to obtain a PEF treatment solution. Centrifuge with a separation factor of 5310G to separate the protein in the lower layer, the heavy liquid in the middle layer, and the light liquid in the upper layer, and collect the light liquid to obtain 50g of abalone oil.

Embodiment 2

[0023] At 20°C, take 10kg of washed abalone viscera, add 10°C distilled water according to the material-to-liquid ratio of 1:2, beat, and pass through a 40-mesh sieve to prepare a 10°C pretreatment solution. The pretreatment solution was treated by a high-voltage pulsed electric field with an electric field intensity of 20kV / cm, a frequency of 1000Hz, a pulse width of 2.0μs, and a treatment time of 1200μs to obtain a PEF treatment solution. The separation factor is centrifuged under the condition of 14300G, and the protein in the lower layer, the heavy liquid in the middle layer, and the light liquid in the upper layer are separated, and the light liquid is collected to be 120g of abalone oil.

Embodiment 3

[0025] At 30°C, take 10kg of washed abalone viscera, add distilled water at 20°C according to the material-to-liquid ratio of 1:4, beat, and pass through a 40-mesh sieve to prepare a normal temperature pretreatment solution. The pretreatment solution was treated by a high-voltage pulsed electric field with an electric field intensity of 25kV / cm, a frequency of 1000Hz, a pulse width of 5.0μs, and a treatment time of 800μs to obtain a PEF treatment solution. The tube separator with a separation factor of 15700G separates the protein, heavy liquid and light liquid, and collects the light liquid to obtain 136g of abalone oil.

Abstract

The invention relates to an extraction technology of abalone oil. The extraction technology comprises the following steps: pulping cleaned fresh abalone organs to obtain pretreatment solution, treating the pretreatment solution at low temperature or room temperature in a high-voltage pulsed electric field (PEF) to obtain a PEF treatment solution; and centrifuging the obtained PEF treatment solution to perform effective separation, thus obtaining the abalone oil. In the extraction technology, the PEF cell membrane electroporation technology and centrifugal separation are utilized to effectively extract oil components in the abalone organs and increase the yield of the abalone oil. Meanwhile, after the treatment in the PEF, lipoxidase is deactivated to a certain extent, thus the problem that oil is oxidized in the extraction process can be effectively solved, and the oxidation of polyunsaturated fatty acids in fish oil such as DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid) can be reduced to the greatest extent.

Description

technical field [0001] The invention relates to a process for extracting abalone oil from fresh abalone viscera. Background technique [0002] Sea fish oil is rich in polyunsaturated fatty acids DHA and EPA, which are necessary for the human body. EPA is eicosapentaenoic acid, and DHA is docosahexaenoic acid. They both belong to the omega-3 series of polyunsaturated fatty acids. They are both omega -3 Long-chain polyunsaturated fatty acid a-linolenic acid metabolites and is an essential fatty acid that humans cannot synthesize by themselves. Medical and nutritional research over the past 20 years has shown that EPA and DHA have the ability to inhibit platelet aggregation, anti-thrombotic dilation, and blood vessel adjustment. Elevate HDL (high-density lipoprotein cholesterol) in the blood and reduce LDL (low-density lipoprotein cholesterol) in the blood. The functions of treating and preventing cardiovascular and cerebrovascular diseases are also effective for diabetic infla...
