Embodiment 1

[0019] The method for removing fishy smell from DHA algae oil and fish oil comprises the following steps:

[0020] S1. Under water bath conditions, control the temperature of the water bath at 30 degrees Celsius, then add yeast powder with a quality of 3% of the DHA algae oil or fish oil to the DHA algae oil or fish oil, and then heat in the water bath for 15 minutes for preliminary deodorization;

[0021] S2. Import the DHA algae oil or fish oil obtained after the initial deodorization into the ozone generating device for sufficient stirring, and the stirring time is controlled at 20 minutes, and then the DHA algae oil or fish oil after the second deodorization can be obtained;

[0022] S3. Fully react the hydroxylamine whose quality is 1% of DHA algae oil or fish oil with the DHA algae oil or fish oil obtained in S2, and then separate the oil and water to obtain the deodorized DHA algae oil or fish oil.

[0023] Known by embodiment 1: the DHA algal oil or fish oil that above...

Embodiment 2

[0025] The method for removing fishy smell from DHA algae oil and fish oil comprises the following steps:

[0026] S1. Under water bath conditions, control the temperature of the water bath at 32 degrees Celsius, then add yeast powder with a quality of 3.5% of DHA algae oil or fish oil to the DHA algae oil or fish oil, and then heat in the water bath for 18 minutes for preliminary deodorization;

[0027] S2. Import the DHA algae oil or fish oil obtained after preliminary deodorization into the ozone generating device for sufficient stirring, and the stirring time is controlled at 23 minutes, and then the DHA algae oil or fish oil after second deodorization can be obtained;

[0028] S3. Fully react the hydroxylamine whose quality is 3% of DHA algae oil or fish oil with the DHA algae oil or fish oil obtained in S2, and then separate the oil and water to obtain the deodorized DHA algae oil or fish oil.

Embodiment 3

[0031] The method for removing fishy smell from DHA algae oil and fish oil comprises the following steps:

[0032] S1. Under water bath conditions, control the temperature of the water bath at 45 degrees Celsius, then add yeast powder with a quality of 4.5% of DHA algae oil or fish oil to the DHA algae oil or fish oil, and then heat in the water bath for 25 minutes for preliminary deodorization;

[0033] S2. Import the DHA algae oil or fish oil obtained after the preliminary deodorization into the ozone generating device for sufficient stirring, and the stirring time is controlled at 30 minutes, and then the DHA algae oil or fish oil after the second deodorization can be obtained;

[0034] S3. Fully react the hydroxylamine whose quality is 10% of DHA algae oil or fish oil with the DHA algae oil or fish oil obtained in S2, and then carry out oil-water separation to obtain deodorized DHA algae oil or fish oil.

Abstract

The invention discloses a DHA algal oil and fish oil deodorization method which comprises the following steps: S1, adding yeast powder into DHA algal oil or fish oil under a water bath condition, andperforming preliminary deodorization reaction treatment to obtain DHA algal oil or fish oil subjected to preliminary deodorization. According to the invention, yeast powder is added for preliminary deodorization of DHA algal oil or fish oil, so that most fishy smell of DHA algal oil or fish oil can be effectively removed; then the DHA algal oil or fish oil after preliminary deodorization is fullystirred through an ozone generation device, so that the DHA algal oil or fish oil can be further deodorized; and then the DHA algal oil or fish oil subjected to secondary deodorization is reacted withhydroxylamine to obtain DHA algal oil or fish oil; therefore, the fishy smell of the DHA algal oil or fish oil is completely removed, the utilization rate and economic value of the DHA algal oil or fish oil are effectively improved. The effects of simple process, low energy consumption, short consumed time, high efficiency and capability of completely removing the fishy smell of the DHA algal oilor fish oil are achieved, and the method is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of removing fishy smell from DHA algae oil and fish oil, in particular to a method for removing fishy smell from DHA algae oil and fish oil. Background technique [0002] Fish oil is the general term for all oils in fish, derived from the body of large marine fish, and its main component is Omega-3 fatty acids (including DHA and EPA), which is a polyunsaturated fatty acid that can reduce inflammation and reduce inflammation. Blood fat, prevention of cardiovascular disease. [0003] Algae oil is a pure vegetable DHA (DHA, docosahexaenoic acid, commonly known as brain gold, is a very important polyunsaturated fatty acid for the human body, and belongs to an important member of the Omega-3 unsaturated fatty acid family. [0004] The existing methods for removing fishy smell from algae oil and fish oil generally use methods such as high-pressure distillation under reduced pressure or adding odor-masking agents....
