Embodiment 1

[0026] A new type of high-nutrition rapeseed oil, including 5% linseed oil, 94% rapeseed oil, 1% additive (vitamin E).

[0027] The preparation method of above-mentioned novel high-nutrition rapeseed oil comprises the following specific steps:

[0028] S1. Pass the linseed through a 10-mesh sieve, remove other impurities, and pulverize the screened linseed oil;

[0029] S2. Cold pressing the screened linseed, the temperature of the cold pressing is 15°C, and filtering after pressing 4 times;

[0030] S3. placing the filtered linseed oil at 20° C. for static precipitation for 30 minutes to obtain refined linseed oil;

[0031] S4. Mixing refined linseed oil, additives and rapeseed oil evenly to obtain a mixture;

[0032] S5. Pass the mixture through a 1 mm mesh to remove the residue, bottle it and seal it at 110° C. for sterilization. The sterilization time is 10 minutes to obtain a novel high-nutrition rapeseed oil.

[0033] The invention adds linseed oil to the rapeseed oil...

Embodiment 2

[0035] A new type of high-nutrition rapeseed oil, including 10% linseed oil, 87% rapeseed oil, 3% Phaffia astaxanthin. The main unsaturated fatty acid content of the novel high-nutrition rapeseed oil is shown in Table 1. It can be seen from Table 1 that the additive Phaffia astaxanthin plays a role in protecting unsaturated fatty acids from being oxidized into saturated fatty acids. The contents of linolenic acid and linoleic acid in this example are higher than that of pure rapeseed oil, indicating that flaxseed The nutritional value of oil and rapeseed oil is complementary, and the nutritional value of rapeseed oil is improved by mixing part of linseed oil in rapeseed oil.

[0036] The preparation method of above-mentioned novel high-nutrition rapeseed oil comprises the following specific steps:

[0037] S1. Pass the linseed through a 30-mesh sieve, remove other impurities, and pulverize the screened linseed oil;

[0038] S2. Cold pressing the screened linseed, the tempera...

Embodiment 3

[0045] A new type of high-nutrition rapeseed oil, including 7% linseed oil, 91% rapeseed oil, 2% vitamin C.

[0046] The preparation method of above-mentioned novel high-nutrition rapeseed oil comprises the following concrete steps:

[0047] S1. Pass the linseed through a 12-mesh sieve, remove other impurities, and pulverize the screened linseed oil;

[0048] S2. cold-pressing the screened linseed, the temperature of the cold-pressing is 17°C, and filtering after 5 times of pressing;

[0049] S3. placing the filtered linseed oil at 23° C. for 55 minutes, and performing precipitation treatment to obtain refined linseed oil;

[0050] S4. uniformly mixing refined linseed oil, vitamin C and rapeseed oil to obtain a mixture;

[0051] S5. After passing the mixture through 8mm mesh to remove the residue, bottle it and seal it at 114° C. for sterilizing treatment. The sterilizing time is 13 minutes to obtain a novel high-nutrition rapeseed oil.

Abstract

The invention discloses a novel high nutritional value rapeseed oil, and a preparation method thereof. The novel high nutritional value rapeseed oil comprises 5 to 10% of flaxseed oil, 87 to 94% of rapeseed oil, and 1 to 3% of an additive; the additive is Phaffia rhodozyma astaxanthin or vitamin. According to the preparation method, a small amount of flaxseed oil is added into rapeseed oil, so that the nutritional value of daily rapeseed oil is increased, and cost is reduced at the same time, the content of essential fatty acid flaxseed needed by human body normal growth and health of daily rapeseed oil is increased, the nutritional value of edible oil is increased; rapeseed oil is beneficial for bladder functions, and is beneficial for reduction of cholesterol in human body. In eating, rapeseed oil is combined with flaxseed oil rich in linoleic acid, the nutritional value is increased. The novel high nutritional value rapeseed oil is high in nutritional value, appropriate in cost, andpromising in market prospect.

Description

technical field [0001] The invention belongs to the field of food processing, and more specifically relates to a novel high-nutrition rapeseed oil and a preparation method thereof. Background technique [0002] Linolenic acid is an essential fatty acid that plays a decisive role in human health. It is the basic substance that constitutes cell membranes and biological enzymes. It also plays an important role in maintaining lipoprotein balance, lowering blood fat, regulating cholesterol metabolism, lowering blood pressure, antithrombotic, preventing cancer, etc., and has the effect of protecting eyesight. Linolenic acid is an essential unsaturated fatty acid, which cannot be synthesized by the human body. It must be supplemented by diet. Making flaxseed oil into linolenic acid is an effective way to supplement linolenic acid. However, the high cost of linseed oil makes it difficult to popularize in every family. . Studies have shown that rapeseed oil is beneficial to gallbla...
