Conventional food crops such as rice and corn are hard-hit areas for the illegal cultivation and sale of genetically modified crops. Occurrences occur in our country on a regular basis. Therefore, in order to ensure food security in China, the Ministry of Agriculture issued the 2015 “Agricultural GMO Safety Supervision Work Planâ€. Mentioned that the rice, corn and other major monitoring, it is recommended to use test strips and other rapid detection methods to reduce costs and expand the scope of monitoring. Here is an important product that is GM test paper, the use of genetically modified test paper for rapid detection of transgenes, its significance.
The HAE TIJ printer offers an idea solution to move from messy low resolution Drop On Demand (DOD), Roller Coders or expensive to operate and service continuous inkjet marking printer (CIJ) to a high quality, high resolution HAE Thermal Ink Jet Printer (TIJ) using the latest original HP ink cartridges for reliable print onto primary and secondary packaging.

The genetically modified material is invisible and invisible. To accurately capture its “image†must use certain techniques and means. In the past, it was necessary to check whether the crop was a genetically modified product. The PCR transgenic instrument was used. This kind of traditional PCR transgenic detector Because of its large size and high price, it can only be used in the laboratory. In other words, to test GM crops, samples must be sent to laboratories. Qualitative tests are performed using professional instruments for several hours, and the price of a test is also very expensive. It is not suitable for large-scale promotion and use.
The application of genetically modified test paper has changed this passive situation. First, the cost of genetically modified test paper is low. Using it for rapid detection does not require high cost and time cost. Secondly, it is convenient to carry and is equivalent to a mobile. The laboratory can detect genetically modified seeds and crops wherever and whenever appropriate, and can obtain test results in the field. Through this convenient and low-cost detection method, the possibility of illegally GM foods entering the market will be greatly increased. reduce.
Most transgenic plants are likely to mix foods during cultivation, harvesting, transportation, storage, and processing. Therefore, in order to enhance food safety and crop planting safety, it is necessary to strengthen the scope and frequency of genetic testing, and use genetically modified test paper to meet modern agriculture. Reducing costs and expanding the scope of monitoring can play an important role in preventing the illegal proliferation of genetically modified crops.
