Problems solved by technology

And the alkalized adsorbent may destroy the regular hydrogen bonds between molecules due to the addition of alkali, so that the intermolecular force is weakened, the molecular chain activities become free, the thermal decomposition temperature decreases, and the stability decreases.

Embodiment 1～7

[0039] The deacidification process in the present invention includes the following steps:

[0040] Put the adsorbent into the dielectric barrier plasma generator whose barrier medium is polymethyl methacrylate, adjust the voltage to 10-20kV, the distance between the upper and lower electrodes is 5-30mm, and the voltage frequency is 30-50kHz. The gas first passes through a bubbler filled with alkaline solution, and then into the plasma generator. Adjust the working gas flow to 20~40L·min -1 , Turn on the AC power switch of the plasma generator, perform plasma treatment for 50~120s, and the working gas is N 2 , NH 3 One or two of them, the alkaline solution is NaOH solution, KOH solution, Ca(OH) 2 One or more in the solution, the adsorbent is one or more of activated carbon, clay, and diatomaceous earth; then continue to pass N 2 30~60s;

[0041] Afterwards, remove the adsorbent, store it in an inert gas or add it to the degummed fish oil immediately. The addition amount is 0.5 to 3.5...

Abstract

The invention relates to a fish oil deacidification process and belongs to the technical field of aquatic product processing. The method comprises the steps as follows: placing an adsorbent into a plasma generating device for plasma treatment; adding the adsorbent to degummed fish oil for deacidification treatment after plasma treatment; performing centrifugation to obtain a supernatant, namely, the deacidified fish oil. The fish oil deacidification process has the advantages of simple reaction process, good deacidification effect, high efficiency and little pollution and is easy to control and free of public hazard, and effective nutrient substances in the fish oil are not damaged.

Description

Technical field [0001] The invention belongs to the technical field of aquatic product processing, and relates to a fish oil deacidification process. Background technique [0002] Deacidification is an important part of oil refining. The current deacidification methods include molecular distillation deacidification, alkali refining and deacidification, physical refining and deacidification, organic solvent extraction and supercritical fluid extraction and deacidification. Among them, alkali refining and deacidification are industrial The most commonly used method above has a good deacidification effect, but subsequent washings are required to remove fatty acid salts, and then vacuum to remove water. It has disadvantages such as complex process, high energy consumption, and environmental pollution; molecular distillation requires high pretreatment And the equipment is expensive; physical refining and deacidification is not suitable for heat-sensitive grease; the cost of extraction...
