Embodiment 1

[0039] A food safety risk online assessment and control method, such as figure 1As shown, the following steps are included: (1) Determine the industrial chain; (2) Determine the material input point i with material input on the industrial chain, and correspond to the sampling point at the input point i, and set other sampling points in addition according to HACCP requirements; (3) Risk assessment: Calculate the sampling density, the content of hazard factors at the input point, the risk index, and the degree of risk to evaluate the risk of the final product; (4) Early warning: conduct early warning analysis based on the evaluation results of step (3), and enter the step for high risk (5), low-risk, enter the next sampling point and repeat step (3); (5) traceability: step (4) early warning enters the traceability program, finds the hazard node on the industrial chain, and enters step (6) when the node is the input point of the input , the hazard node is not the input point of t...

Embodiment 2

[0041] Taking the rice production and processing industry chain as an example, the specific operation steps of the online rice safety risk assessment and control method are as follows:

[0042] (1) Determine the rice industry chain: establish an industry chain including rice production and processing according to the rice processing process, such as figure 2 shown;

[0043] (2) Determine sampling points and material input points: according to the industrial chain determined in step (1), set sampling point j on the industrial chain, set the first sampling point 1 at the paddy, and set the first sampling point 1 at the paddy after processing into rice and before polishing. Two sampling points 2, the polishing agent water in the polishing process is the third sampling point 3, the rice added in the rice blending process is the fourth sampling point 4, the fifth sampling point 5 is set at the finished product, and the same sampling point is calculated The time C between the two ...

Embodiment 3

[0068] A food safety risk online assessment and control method, the process flow is as follows figure 1 shown. The online assessment and control method of food safety risk is applied to the online assessment and control of heavy metal content in rice, and the specific steps are as follows:

[0069] (1) Determine the industrial chain: determine the industrial chain of food from source to dining table, including food production and processing technology; and industrial branch chains including all inputs, such as image 3 shown;

[0070] (2) Determine the sampling points and material input points: list the material input points during the processing process. In the main industrial chain, the material input points are polishing and rice blending. In the industrial branch chain, the material input points are also polishing With rice distribution; the setting of the sampling point of the main industry chain is the same as that of embodiment 2, and each processing node in the branc...

Abstract

The invention belongs to the technical field of food safety traceability, and specifically relates to an online food safety risk assessment and control method, comprising the following steps: (1) determining the industrial chain, (2) determining the material input point i on the industrial chain with material input and Corresponding sampling points; (3) Risk assessment of input points or sampling points; (4) Early warning analysis according to the risk assessment results of step (3), high risk enters step (5), and low risk enters the next sampling Repeat step (3) at the point or input point; (5) trace the source, (6) adjust the content of the risk factor in the input at the input point, and continue to cycle step (3) after adjustment. The control of pollutants in the food processing process of the present invention can realize prevention in advance and avoid risks in advance, and can complete the pre-judgment of the content of pollutants in the final product before the production of the product is completed, reducing the risk of pollutants in food and reducing the risk of pollutants in food. The source of the hazard can be found in time.

Description

technical field [0001] The invention belongs to the technical field of food safety traceability, and in particular relates to an online food safety risk assessment and control method. Background technique [0002] Food is the most important thing for the people, and the quality and safety of food has a major impact on human health and social stability. For example, heavy metal pollution, aflatoxin pollution, Escherichia coli pollution, and pesticide residues are serious hazards. Once they exceed the standard, they will seriously affect the health of consumers and even endanger their lives. Therefore, taking timely and effective measures, establishing a traceability system for the entire industry chain, conducting investigations of pollution sources, and quickly and accurately discovering pollution sources can effectively inhibit the spread of pollution, maintain social stability, and reduce the harm of food pollution to the human body. [0003] At present, my country's food...
