Abstract

The invention discloses a method for continuously extracting wheat germ oil by using a microwave-assisted solvent. The method comprises the following steps of screening raw materials; drying wheat germs; preparing wheat germ powder; carrying out microwave irradiation; obtaining the extracted oil; carrying out extraction; carrying out filtration; carrying out extracting liquid separation; and carrying out secondary filtration. According to the method, the wheat germ powder is subjected to continuous extraction through the microwave-assisted solvent, so that the extraction efficiency of the wheat germ oil is higher, the wheat germs are cleaned and dehumidified in advance, so that the prepared wheat germ powder is much cleaner, the content of impurities in the wheat germ oil is decreased, andthe wheat germ powder is subjected to auxiliary wall breaking and extraction through the microwave, so that the extraction rate of the wheat germ oil is increased; and the wheat germ oil is continuously extracted, so that the extracted wheat germ oil is much purer and less in impurity content.

Description

technical field [0001] The invention belongs to the field of separation and extraction of active components in natural products, and in particular relates to a method for continuously extracting wheat germ oil with a microwave-assisted solvent. Background technique [0002] Wheat germ oil is a kind of grain germ oil made from wheat germ. It concentrates the nutritional essence of wheat and is rich in vitamin E, linoleic acid, linolenic acid, octadecyl alcohol and various physiologically active components. It is a valuable functional food with high nutritional value. In particular, the content of vitamin E is the highest among vegetable oils, and it has been recognized as a functional oil with nutritional and health effects. It can regulate endocrine, lose weight, prevent stains, dark spots and pigmentation; anti-oxidation, reduce lipid peroxide production, promote skin moisturizing function, make skin moist, delay aging; promote metabolism and skin renewal, anti-wrinkle, an...
