Convergence risk early warning method in food detection

Abstract

The invention discloses a convergence risk early warning method in food detection. The method comprises the following steps of preparing a standard sample for convergence detection, measuring by using an ultraviolet and visible spectrophotometer and a gas chromatograph detector, and determining standard values of a spectrum and chromatography food safety instrument to obtain an effective convergence boundary constraint condition system; and establishing an optimal model, carrying out actual verification, establishing an optimal measurement capability index evaluation index according to an economic and reasonable principle, dividing convergence risk early warning of a measurement system into five grades, and adopting different management countermeasures for different early warning grades. According to the invention, the dynamic state of the spectrum and chromatography food safety detection instrument when the risk is in the germination state can be mastered, accurate early warning can be carried out, control measures can be taken in time, occurrence and deterioration of the convergence risk of the food safety detection instrument are prevented, food quality and safety are effectively guaranteed, and modernization and informatization of spectrum and chromatography food safety detection instrument management are promoted.

Description

technical field [0001] The invention relates to the technical field of food safety detection, in particular to a method for early warning of convergence risk in food detection. Background technique [0002] At present, the food safety situation is not optimistic. In order to eliminate the restrictive effect of various food safety problems such as food-borne diseases on economic development, all countries are striving to improve the performance level of food safety regulations. The food safety regulatory system and system, especially in solving major food safety problems, already have advanced testing instruments and methods, which can detect various problems caused by food, so as to achieve early detection and early prevention, and take food safety measures as soon as possible. risk warning measures; [0003] In the field of food quality and safety, the accuracy of food testing instruments has a direct impact on the validity and accuracy of testing data, which is the basis ...

Problems solved by technology

[0004] The development trend of sample pretreatment technology is fast speed, large batch, high degree of automation, low cost, low labor intensity, less reagent consumption, beneficial to personnel health and environmental protection, and accurate and reliable methods. Therefore, spectroscopic and chromatographic food safety testing instruments are accurate There is no unified evaluation standard and no restrictions on application conditions, which will lead to misjudgment of data, and insufficient risk warning that the quantitative values ​​of spectral and chromatographic detection instruments are difficult to converge, which will have an adverse impact on food safety. Today, any small difference in standard value will lead to serious economic conflicts and social stability issues. Therefore, the present invention proposes a method for early warning of convergence risks in food testing to solve the problems existing in the prior art. question
