Preparation method and inspection method for fluorescent magnetic powder dual anti-counterfeiting pelleted seeds

Abstract

The invention provides a preparation method for fluorescent magnetic powder dual anti-counterfeiting pelleted seeds. The preparation method comprises the steps that naked seeds are coated with first seed coating to form pelleted seeds, and then second seed coating and a certain amount of magnetic powder are mixed and coated on the pelleted seeds. The pelleted seeds obtained through the method have two-layer structures, wherein an inner-layer structure close to the naked seeds contains a fluorescent color agent and an outer-layer structure contains the magnetic powder. The pelleted seeds can be authenticated through magnetic materials and exciting light with certain wavelength. By conducting simple adjustment on the premise that the original pelleting process flow is not changed, the preparation method has the advantages that the equipment is not required to be updated and the anti-counterfeiting cost is low. The appearance of the pelleted seeds with dual anti-counterfeiting functions is not different from the appearance of common pelleted seeds and the pelleted seeds can be authenticated only through a specific inspection method. The preparation method provides a simple and reliable anti-counterfeiting technique for seeds, and the protection of the quality of the seeds and the protection of the benefits of seed companies and seed users are enhanced.

Description

technical field [0001] The invention relates to a seed anti-counterfeiting technology, in particular to a preparation method of fluorescent magnetic powder double anti-counterfeiting pilled seeds, and also relates to a method for identifying the anti-counterfeiting seeds. Background technique [0002] Seeds play an important role in the national economy, but seeds are often counterfeited by criminals, which brings great harm to agricultural production and farmers. Regarding the anti-counterfeiting of seeds, anti-counterfeiting packaging technology is generally used in the industry at present. Seed packaging is the direct carrier of seed sales, so anti-counterfeiting of seed packaging has naturally become a more direct and effective solution for seed companies to combat counterfeiting, maintain the normal order of the seed market, and protect their own interests and legal rights. However, the confusion of the packaging industry and the confusion of anti-counterfeit products ...

Problems solved by technology

[0009] However, the existing fluorescent anti-counterfeiting method belongs to a single anti-counterfeiting method, and its disadvantage is that only one fluorescent substance is added when the seeds are pelletized, the detection method is single, and the anti-counterfeiting security is low, and it can only be carried out when the seeds are cracked. Anti-counterfeiting detection, the seedlings cannot be anti-counterfeiting

[0010] The present invention is a double anti-counterfeiting method for pelleted seeds, which applies fluorescent substances and magnetic materials to pelleted seeds at the same time, and increases the fluorescent anti-counterfeiting while ensuring that the magnetic materials and the treatment method have no toxic effect on seed germination and seedling growth. technology, to avoid the high cost of anti-counterfeiting of packaging materials to the greatest extent, and the anti-counterfeiting method is flexible and the detection is sensitive, which is still blank in the field of seed research at home and abroad
