Embodiment 1

[0074] Embodiment 1, alcohol traceability method

[0075] As we all know, how to effectively anti-counterfeit is very important and has high commercial value for alcohol, especially famous brand liquor, red wine, beer, wine and fruit wine. Among the anti-counterfeiting methods retrieved above, the traceability of each product is a good and effective method. Therefore, the present invention adopts DNA technology to realize traceability, which is an important intention of the invention. The DNA is deoxyribonucleic acid.

[0076] In the present invention, the sample producer who adopts the method of the present invention is called a manufacturer, and the person who uses the sample is called a user.

[0077] The specific plan is as follows:

[0078] figure 1 It is a step diagram of the method of wine traceability, such as figure 2 is the detailed steps, image 3 , Figure 4 , Figure 5 They are the encoding process steps, marking process steps and verification process ste...

Embodiment 2

[0193] Embodiment 2, food traceability method

[0194] This embodiment is a food traceability method of the present invention. Compared with Example 1, the similarity is not described, and the difference is:

[0195] 1. The sample includes a food product.

[0196] 2. The specific DNA and interfering DNA must not have any chemical reaction with the food using this method, and must not affect the taste.

[0197] 3. For foods with disposable packaging, such as plastic bag packaging, paper bag packaging, etc., the specific DNA and interfering DNA can be mixed on the packaging or marked in the printing pigment of the packaging.

[0198] 4. In the database D1 or database D2, record the expiry date of the food in the database D1 and the uniquely coded batch information. At this time, traceability includes checking the expiry date of the food.

[0199] 5. When using the direct measurement method to trace the source, design a unique code for the smallest package of each product, inc...

Embodiment 3

[0200] Embodiment 3, pan-material traceability method

[0201] This embodiment is a pan-substance traceability method of the present invention. Compared with embodiment 1 and embodiment 2, similarity is not described, and difference is:

[0202] 1. The samples include various material products.

[0203] 2. The specific DNA and interfering DNA must not have any chemical reaction with the ubiquitous product using this method, and must not affect the performance of the ubiquitous substance.

[0204] 3. For ubiquitous products in disposable packaging, such as plastic bag packaging, paper bag packaging, etc., the specific DNA and interfering DNA can be mixed on the packaging or marked in the printing pigment of the packaging.

[0205] 4. In the database D1 or database D2, record the individual characteristic information of the ubiquitous product in the database D1 and the uniquely coded batch information. At this time, the traceability includes checking the individual characteris...

Abstract

The invention discloses a method for tracing DNA (Deoxyribose Nucleic Acid) of a substance. The method is an addition method and comprises the following steps: designing and synthesizing specific DNA and a confidential primer, and adding the specific DNA at a sample source; carrying out DNA amplification sequencing and tracing on the sample according to the confidential primer; the method comprises the following steps: establishing a specific DNA database D2 of a sample source; and carrying out DNA sequencing and tracing on the sample. According to the method, content anti-counterfeiting can be widely carried out in a low-cost mode, information management anti-counterfeiting traceability is carried out by using a block chain technology, the method is a comprehensive traceability anti-counterfeiting method combining management anti-counterfeiting and technical anti-counterfeiting, and the traceability anti-counterfeiting safety is greatly improved by utilizing the characteristic of high information content of DNA.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a method for traceability of material DNA. Background technique [0002] Traceable anti-counterfeiting methods can generally be divided into management and technical methods. Management anti-counterfeiting is also called soft anti-counterfeiting, which refers to achieving the purpose of anti-counterfeiting and traceability through certain management means, but usually the steps are complicated and the management cost is high. Technical anti-counterfeiting, also known as hard anti-counterfeiting, refers to achieving the purpose of anti-counterfeiting and traceability through certain technical means. Technical anti-counterfeiting can be divided into two types: form anti-counterfeiting and content anti-counterfeiting. At present, most anti-counterfeiting technologies and methods belong to formal anti-counterfeiting, such as anti-counterfeiting packaging, passwords, logos or trademarks, ...
