preparation example Construction

[0048] According to the preparation method of the present invention, the cholesterol removal rate of the fat composition with reduced cholesterol content varies depending on the source of the animal fat, and is 30-90% by weight.

[0049] Process (4) and Process (5)

[0050] In the preparation method of the present invention, in addition to the primary removal of cholesterol through the above-mentioned steps (1) to (3), it is also possible to further carry out secondary removal or multiple removal of cholesterol after step (3). . Specifically, after the step (3), the following steps (4) and (5) are carried out at least once in sequence:

[0051] Step (4): adding rice husk ash to the product obtained in the above step, making the product contact with rice husk ash; and

[0052] Step (5): removing rice husk ash.

[0053] Regarding step (4), in order to further improve the removal rate of cholesterol, rice husk ash is further added to the oil composition with reduced cholestero...

preparation example 1

[0085] Preparation example 1 (preparation of rice husk ash 1)

[0086] The rice hulls are washed with water more than 3 times to remove all attached soil and other impurities. Drying can be performed in a drying oven at a temperature of 60° C. for 1 day.

[0087] Then, a certain amount of rice husks are placed in a closed incinerator, heated to 300°C at a heating rate of 10°C / min, and kept at this temperature for 0.5 hours, and then slowly allowed to cool to room temperature, thereby obtaining the present invention. Rice husk ash used 1.

[0088] In rice hull ash 1, the content of silicon dioxide was 50% by weight, the ratio of activated carbon was 49.9% by weight, and the ratio of silicon dioxide / activated carbon was 1:1.

preparation example 2

[0089] Preparation example 2 (preparation of rice husk ash 2)

[0090] The rice hulls are washed with water more than 3 times to remove all attached soil and other impurities. Drying can be done in a drying oven at a temperature of 120° C. for 2 days.

[0091] Then, a certain amount of rice husks are placed in a closed incinerator, heated to 400°C at a heating rate of 12°C / min, and kept at this temperature for 1 hour, and then slowly allowed to cool to room temperature, thereby obtaining the present invention. Rice husk ash used 2.

[0092] In rice hull ash 2, the content of silicon dioxide was 58.5% by weight, the ratio of activated carbon was 39% by weight, and the ratio of silicon dioxide / activated carbon was 3:2.

Abstract

The invention provides a method for reducing the content of cholesterol in fats and oils, which comprises the following steps: step (1): melting animal fats; step (2): adding rice husks to the melted animal fats obtained in the above step (1) ash, contacting molten animal fat with rice husk ash; step (3): removing the rice husk ash. The method can effectively reduce the cholesterol content in the oil with low cost. Moreover, the present invention also provides a fat composition with reduced cholesterol content, which is obtained by the method for reducing cholesterol content in fats and oils of the present invention. Furthermore, the present invention provides an oil and fat product containing the cholesterol-reduced oil and fat composition of the present invention.

Description

technical field [0001] The invention relates to a method for reducing the content of cholesterol in oil, an oil composition obtained by the method, and an oil product containing the oil composition. Background technique [0002] Cholesterol is an indispensable substance for human metabolism, but excess cholesterol is one of the causes of human cardiovascular disease. Regarding the impact of cholesterol on human health, it is generally believed that ordinary consumers, especially those with cardiovascular disease, should be cautious about cholesterol. According to the recommendations of several international organizations and the Chinese Nutrition Society, the cholesterol intake of normal people should not be higher than 300mg / day. On the other hand, with regard to consumers’ awareness of dietary cholesterol intake, according to a survey report by the American Medical Research Association: 72% of adults believe that lowering serum cholesterol levels is beneficial to health, ...
