Problems solved by technology

However, linseed oil is rich in unsaturated fatty acids, and Chinese residents prefer the unique flavor of linseed oil, so linseed oil is not suitable for refining after pressing
In the prior art, the linseed oil is usually debittered after the linseed oil is contacted with a mixture of dehulled linseed meal powder and diatomaceous earth, or silica gel and resin are used to debitter the linseed oil, but there is no debittering effect on the linseed oil. Bitterness phase is strictly controlled, resulting in loss of nutrients in debittered linseed oil

Embodiment 1

[0026] The present invention proposes a method for removing the bitterness of linseed oil, comprising the following steps:

[0027] S1: Add 0.1-0.3% of linseed oil to the linseed oil at a temperature of 45°C for enzymolysis, and keep stirring for 20-80 minutes;

[0028] Here, the enzyme selects at least two of protein short peptide "cyclic octapeptide" enzyme, pectinase or cellulase;

[0029] The steps of enzymatic hydrolysis are:

[0030] A1: Add baking soda to the linseed oil to adjust the pH between 7.0 and 7.5;

[0031] A2: Add protease to linseed oil, and carry out hydrolysis in an ultrasonic-assisted extraction apparatus, wherein the ultrasonic power range is 40-80W, the microwave power range is 100-500W, the processing time is 1-5min, and the temperature is controlled at 45-60°C;

[0032] A2: After the hydrolysis is completed, put it into a stirring tank, the speed is 80r / min, the duration is 20-80min, and the heat is naturally dissipated.

Abstract

The invention discloses a method for removing the bitter taste of linseed oil, and the method comprises the following steps: S1, adding an enzyme with the mass of 0.1-0.3 wt% of the mass of linseed oil into the linseed oil at the temperature of 45-60 DEG C for enzymolysis, and continuously stirring for 20-80 minutes; s2, adding a bitterness inhibitor into the linseed oil subjected to enzymolysis in the step S1 for blending; and s3, under a low-temperature condition, feeding the linseed oil treated by the bitterness inhibitor into a centrifugal machine to be centrifuged, and separating out bitterness substances. Protein in the linseed oil is subjected to enzymolysis through the enzyme, generation of the bitter substances is accelerated, the bitter inhibitor is added into the linseed oil obtained after enzymolysis to destroy the bitter substances, and then the bitter substances are classified through centrifugation, extraction and other methods so as to reduce the bitter taste generatedafter linseeds are stored for a long time.

Description

technical field [0001] The invention relates to the technical field of linseed oil production, in particular to a method for removing the bitterness of linseed oil. Background technique [0002] Flaxseed oil, also known as linseed oil and linseed oil, is one of the common edible vegetable oils in Northwest my country. Flaxseed has a high oil content and is often pressed to produce oil. Freshly pressed flaxseed oil has a good taste and no bitterness; however, after a period of storage, flaxseed oil will develop a bitter taste and affect the taste. Refining at high temperature reduces the bitterness of linseed oil and makes the bitterness disappear. However, linseed oil is rich in unsaturated fatty acids, and Chinese residents prefer the unique flavor of linseed oil, so linseed oil is not suitable for refining after pressing. In the prior art, the linseed oil is usually debittered after the linseed oil is contacted with a mixture of dehulled linseed meal powder and diatomac...
