Method for establishing food quality safety detection sample database

Abstract

The invention provides a method for establishing a food quality safety detection sample database. Detection consideration factors of reference sample pollution factors comprise pesticide and veterinary drug residues, heavy metals, chemical pollutants and biotoxins. The method specifically comprises the following steps: defining the range of a database; selecting a data analysis method; selecting and obtaining a real reference sample; collecting analysis data; establishing a database; applying and validating a database; and maintaining a database. The heavy metal contamination index of the reference sample is calculated by using a plurality of separate databases based on the heavy metal contamination index in the indicative food item of the heavy metal concentration. Each heavy metal pollution index comprises a pair of positive index and negative index. The positive index reflects a substance above the maximum allowable concentration, and the negative index reflects a substance below the maximum allowable concentration. According to the method for establishing the food quality safety detection sample database, only heavy metal concentration parameters are needed, and compared with the prior art that additional information such as the intake rate, the weight and the exposure frequency is needed, the method has the advantage that the judgment standard is simpler to operate.

Description

technical field [0001] The invention relates to a database management system, more specifically, to a method for establishing a food quality and safety testing sample database. Background technique [0002] Food health is a common problem and food safety is often detected through the use of analytical tests. Analyzing suspect foods and comparing their results with data contained in food authenticity databases is a typical approach. But the most important considerations that must be addressed when creating a food authenticity database are the scope of the database, analytical methods, sampling, collection and storage of data, etc. However, there is currently no system and method for creating a food authenticity database. [0003] In many links of production, processing, and transportation, food will be polluted by factors such as pesticide and veterinary drug residues, heavy metals, chemical pollutants, and biological toxins. Therefore, in view of the above pollution facto...

AI Technical Summary

Problems solved by technology

However, due to the existence of food with various raw materials, especially raw and processed food, there is no corresponding heavy metal pollution index.

The existing technology requires additional information, such as intake rate, body weight, exposure frequency, etc., and the judgment operation is complicated
