Example Embodiment

[0039] Example 1

[0040] A kind of corn oil contains oryzanol, wherein the oryzanol (by weight percentage) is 0.08. A kind of preparation method of corn oil, concrete steps are as attached figure 1 shown in .

[0041] Wherein the soapstock process obtains the technique of oryzanol as follows:

[0042] (1), extraction:

[0043] Mix rice bran oil saponin with 10 times the amount of methanol evenly, adjust the pH value to 9.5 with 10% sodium hydroxide, heat in a water bath to 35°C, and keep stirring for 0.5 hours;

[0044] (2), separation:

[0045] Cool, let stand and separate for about 1 hour, release the bran oil from the lower layer, collect the methanol extract from the upper layer, and adjust to 3.5 with 10% citric acid solution;

[0046] (3) After methanol is extracted, oryzanol liquid is obtained.

Example Embodiment

[0047] Example 2

[0048] A kind of corn oil contains oryzanol, wherein the oryzanol is 0.14 by weight percentage.

[0049] A kind of preparation method of corn oil, concrete steps are: as attached figure 1 shown in .

[0050] Wherein the soapstock process obtains the technique of oryzanol as follows:

[0051] (1), extraction:

[0052] Mix rice bran oil saponin with 15 times the amount of methanol evenly, adjust the pH to 10 with 15% sodium hydroxide, heat in a water bath to 45°C, and keep stirring for 0.75 hours;

[0053] (2), separation:

[0054] Cool, let stand and separate for about 1.5 hours, release the bran oil from the lower layer, collect the methanol extract from the upper layer, and adjust to 5 with 15% citric acid solution;

[0055] (3) After methanol is extracted, oryzanol liquid is obtained.

Example Embodiment

[0056] Example 3

[0057] A kind of corn oil contains oryzanol, wherein the oryzanol (by weight percentage) is 0.2 parts.

[0058] A kind of preparation method of corn oil, concrete steps are: as attached figure 1 shown in .

[0059] Wherein the soapstock process obtains the technique of oryzanol as follows:

[0060] (1), extraction:

[0061] Mix rice bran oil saponin with 20 times the amount of methanol evenly, adjust the pH to 11 with 30% sodium hydroxide, heat in a water bath to 55°C, and keep stirring for 1 hour;

[0062] (2), separation:

[0063] Cool, let stand for about 2 hours to separate the layers, release the bran oil from the lower layer, collect the methanol extract from the upper layer, and adjust it to 6.5 with 20% citric acid solution;

[0064] (3) After methanol is extracted, oryzanol liquid is obtained.

Abstract

The invention belongs to the field of edible vegetable oil, particularly relates to corn oil rich in oryzanol and a preparation method thereof. The corn oil contains 0.08-0.2% of oryzanol. The corn oil rich in oryzanol is prepared by adding oryzanol into the finished corn oil by reasonable production processes and mixing. The corn oil rich in oryzanol integrates the advantages of corn oil and oryzanol, contains more oryzanol, phytosterin and vitamin E, is balanced in nutrition, and is good for health.

Description

technical field [0001] The invention belongs to the field of edible vegetable oil, in particular to corn oil rich in oryzanol. The invention also relates to a preparation method of the corn oil. Background technique [0002] People's three meals a day are inseparable from oil. It not only makes food delicious and delicious, but also promotes appetite, and it is also an important nutrient substance necessary for normal life activities of the human body. Edible oil is one of the three main food sources for human beings, and the energy it provides accounts for 20% to 50% of the total dietary energy, and is an important source of energy required for life activities. [0003] With the development of the economy and the continuous improvement of people's living standards, the scientificity and rationality of meals have attracted more and more attention. In addition to providing calories, what really attracts people's attention is its nutritional and health functions on the human...
