Preparation method of zanthoxylum seed oil

Abstract

The invention relates to the field of oil material processing, in particular to a preparation method of zanthoxylum seed oil. The method comprises the following steps of: mixing zanthoxylum seeds and excessive sodium hydroxide solution of which the mass percentage is 1.2 to 2.0 percent; under the protection of nitrogen, heating the mixture to saponify the mixture; separating the mixture to obtain the zanthoxylum seeds without epidermis oil fat; and squeezing and refining the zanthoxylum seeds to obtain the zanthoxylum seed oil and also the aqueous solution of sodium aliphatate. The method has the advantages of simpleness in operation, low requirement on equipment, easiness in industrialization and the like. The obtained zanthoxylum seed oil is high in oil extraction rate, low in content of colloid and waxiness, and thick in fragrance, and does not have residual solvent. In addition, the obtained sodium aliphatate can serve as an industrial detergent raw material. Co-production of the zanthoxylum seed oil and the sodium aliphatate is also realized.

Description

technical field [0001] The invention relates to the field of oil processing, in particular to a preparation method of prickly ash seed oil. Background technique [0002] Today, the living environment of human beings is deteriorating day by day, air, water resources, noise and other pollution are serious, and the incidence of "rich diseases" such as high blood pressure, high blood sugar, diabetes, obesity, tumors and cancers is on the rise. The "disease of wealth" has become a major disease that endangers the health of Chinese people. According to the survey, 15-20% of the middle-aged and elderly people in China are constipated, and 60% are white-collar workers; according to the survey of the Ministry of Health, 22% of the people in China are overweight, more than 60 million people seek medical treatment due to obesity, more than 200 million people have high blood pressure, and more than 5000 people have diabetes Ten thousand people, 160 million people with hyperlipidemia. ...

Problems solved by technology

[0005] The preparation method of Zanthoxylum bungeanum seed oil used to be directly crushed and extracted from the whole seed to obtain the mixed oil of skin oil and kernel oil. However, because the skin oil contains a large amount of saturated fatty acids, the acid value and wax value are high, and the taste is poor. The available value is low, which greatly hinders the practical application of Zanthoxylum bungeanum seed oil, and also greatly reduces the quality of kernel oil

At present, many scholars have researched and developed the preparation technology and process of Zanthoxylum bungeanum seed oil. Due to the large difference in particle size range of Zanthoxylum bungeanum, it is difficult to adjust the sheller, resulting in a large amount of seed skin remaining in the obtained Zanthoxylum bungeanum kernel, and the same solvent The two-step extraction method has problems such as high energy consumption and solvent residues in the resulting kernel oil; the Chinese patent No. 98112832 discloses the use of physical methods (rubbing and extraction) to extract the oil from the skin of pepper seeds, and remove the seeds after the skin. Edible oil is obtained by pressing and refining. This invention can obtain two products of broad-spectrum edible oil and industrial oil, but it can be deduced from the peeling and leaching process of the epidermis that the squeezed edible oil will have solvent residue problems; the application number is 99115717 The Chinese patent discloses the use of a squeeze tank to squeeze the skin of the pepper seeds, and then extract the skin oil and kernel oil step by step through the leaching equipment. It can be deduced that the kernel oil obtained by this invention also has the problem of solvent residues.
