Abstract

The invention relates to a method for extracting desoxyribonucleic acid in edible oil, which comprises the following steps of: adding desoxyribonucleic acid extract into the edible oil, and separating out an aqueous phase containing desoxyribonucleic acid after ultrasonic emulsification; and then adding a desoxyribonucleic acid precipitant into the aqueous phase, and precipitating the desoxyribonucleic acid. Because DNA in a sample is enriched by low-energy ultrasonic emulsification in the extracting process, the pretreatment time of the sample is shortened, time consumption is short, the extraction efficiency of the DNA is improved, cross contamination between the samples to be detected is avoided, and the extraction result is more accurate and reliable.

Description

【Technical field】

[0001] The invention relates to a chemical separation process, in particular to a method for extracting deoxyribonucleic acid (DNA) in edible oil. 【Background technique】

[0002] With the development of transgenic technology, various genetically modified products have gradually entered people's lives. On March 20, 2002, China began to implement the "Administrative Measures for the Labeling of Agricultural Genetically Modified Organisms", which stipulates that the country implements an inspection, quarantine and labeling system for agricultural genetically modified organisms. In 2004, China approved the import of herbicide-tolerant genetically modified soybeans (GMO Roundup Ready soybeans), and various genetically modified soybean-related products began to enter the Chinese market in an all-round way. By the end of May 2008, China had imported 9.0×10 transgenic soybeans 6 tons or so. Genetically modified organisms have good market competitiveness and appl...
