Embodiment Construction

[0023] A method for detecting dioxin content in meat products provided by the invention is characterized in that it comprises the following steps:

[0024] -, heating obtains the higher dioxin grease of content, and its steps are as follows:

[0025] a. Take the solid fat of livestock, poultry and other meat products to be tested, heat and melt it into liquid oil, and take 50g of the obtained liquid oil as a sample.

[0026] b. First put pentane into the heating device concentration device, then add 50g of liquid oil obtained into the heating device concentration device, wherein the pentane and the liquid oil are mixed in a ratio of 10:1, and shake the mixture evenly after mixing , so that the liquid oil is completely dissolved in pentane to obtain a mixed solution.

[0027] c. The heating device and the concentration device heat the mixed solution, and the heating temperature is kept between the boiling point of pentane and the boiling point of oil, and kept for a period of ...

Abstract

The invention relates to a method for detecting a dioxin content in meat food. The method is characterized by comprising the following steps: taking an oil sample of a to-be-detected livestock and poultry product; dissolving the sample in pentane to obtain a mixed solution; heating the mixed solution, so that the pentane and most oil in the mixed solution are volatilized in sequence to obtain oilhaving a high content of dioxin; purifying the oil having the high content of dioxin by using a drip washing method; and performing fluorescence analysis on dioxin obtained by purifying, to obtain a result of the dioxin content in the livestock and poultry product. The method provided by the invention has the following advantages: by using the detection method provided by the invention, the sampledoes not need to be sent to a laboratory for detection, the detection is time-saving, quick, convenient, cheap, and easy to operate, a lot of human, material and financial resources are reduced for adetection organization, the detection cost is saved, and the detection efficiency is improved.

Description

technical field [0001] The invention relates to a food quality detection method, in particular to a detection method of dioxin content in meat food. Background technique [0002] With the development of society and the continuous improvement of people's living standards, food safety has attracted more and more attention from governments and people in many countries. Strong, especially in recent years, food safety incidents such as "bird flu", "clenbuterol", "artificial honey" and "dioxin" have made people pay more and more attention to food safety issues. With the development of the times and the economy, people no longer worry about food shortages, and gradually have higher and higher requirements for food quality and safety, especially the food safety of poultry meat. People's demand for poultry meat products has begun From quantity to quality and safety. [0003] Dioxins are widely and persistently present in the environment and are enriched in pollutants in the food ch...
