Problems solved by technology

In addition, conjugated linoleic acid also has antithrombotic properties, which can inhibit platelet aggregation caused by arachidonic acid or collagen. At present, most methods of synthesizing conjugated linoleic acid use vegetable oil rich in linoleic acid as raw materials , which is obtained by isomerization under alkali catalysis, has the disadvantages of high reaction temperature, long reaction time, low yield, and difficult separation and purification.

Embodiment 1

[0020] The invention provides a technical solution: a method for preparing high-content conjugated linoleic acid from grape seed oil, comprising the following steps:

[0021] A. Select fresh grape seeds and wash and dry them in the sun, then put them into a high-temperature sterilization box for high-temperature sterilization. The sterilization temperature is 150°C and the sterilization time is 20 minutes;

[0022] B. Put the grape seeds after high-temperature sterilization in step A into an extruder and squeeze them. The speed of the extruder is 200 rpm, the pressing temperature is 40° C., and the pressing time is 3 minutes to obtain a semi-finished grape seed oil;

[0023] C. Add the semi-finished product of grape seed oil obtained in step B into a fine filter for three times of filtration, remove the filter residue after the first filtration, perform secondary filtration after standing, stir at a low speed after filtration, and then filter three times to obtain grapes after ...

Embodiment 2

[0031] The invention provides a technical solution: a method for preparing high-content conjugated linoleic acid from grape seed oil, comprising the following steps:

[0032] A. Select fresh grape seeds and wash and dry them in the sun, then put them into a high-temperature sterilization box for high-temperature sterilization. The sterilization temperature is 180°C and the sterilization time is 30 minutes;

Abstract

The invention discloses a method of preparing the high-content conjugated linoleic acid using grape seed oil as the raw material. The method comprises the steps that grape seeds are used as the raw material, after the high-temperature sterilization is conducted, the grape seeds are pressed and refinedly filtered, nutrient solution is added in the refined filtration solution, the refined filtration solution is stirred evenly and heated reaction is conducted, extract liquid is added in the reacted solution and semi-finished product of conjugated linoleic acid is extracted, and finally the semi-finished product of conjugated linoleic acid is centrifuged, after desiccation, the finished product of conjugated linoleic acid is obtained. The method is simple in preparation, low in preparation cost, short in preparation time, the obtained conjugated linoleic acid is high in content and high in purity; the conjugated linoleic acid can be directly taken, and high blood fat and high blood sugar can be effectively lowered after long-term taking by the patient, the health care effect is good.

Description

technical field [0001] The invention relates to the technical field of preparation of conjugated linoleic acid, in particular to a method for preparing high-content conjugated linoleic acid from grape seed oil. Background technique [0002] In 1978, M.W.Pariza discovered an antimutagenic substance - conjugated linoleic acid in fried burgers. Subsequently, scientists found that conjugated linoleic acid has many physiological activities. In a variety of animal models, conjugated linoleic acid can prevent cancer, prevent atherosclerosis, regulate metabolism, and reduce body fat content through immune stimulation. Studies have found that conjugated linoleic acid can reduce carcinogen-induced skin cancer, gastric cancer, breast cancer, colon cancer and thymus cancer and breast cancer cells in culture. In addition, conjugated linoleic acid can help regulate or reduce the level of glucose in the blood and prevent the occurrence of diabetes. At the same time, conjugated linoleic ...
