A few days ago, the subject of "Research on the Testing Techniques and Methods of 200 Veterinary Drug Residues in the World" undertaken by Qinhuangdao Inspection and Quarantine Bureau passed the expert identification organized by the Science and Technology Department of the General Administration of Quality Supervision, Inspection and Quarantine.
The Expert Appraisal Committee believes that this subject is aimed at detecting the technical barriers to the detection of 26 types of veterinary drug residues, biotoxins, polycyclic aromatic hydrocarbons and other pollutants encountered in the international market. Significant significance, complete research report data, sufficient data, reliable results, meet the identification requirements. The technical route of the subject is reasonable and feasible. More than ten sample pretreatment technologies such as solid phase extraction, ion exchange, gel permeation, accelerated solvent extraction, derivatization, and enzymatic chemistry have been optimized, and 200 kinds of pollutants have been effectively extracted, separated and enriched. The technology provides a fast and accurate sample preparation method for screening, confirmation, and quantification. The subject research has optimized more than ten analytical techniques such as liquid chromatography, gas chromatography, chromatographic mass spectrometry, immunoaffinity chromatography, and enzyme-linked immunomicrobiology identification, and established a variety of analytical detection methods with sensitivity, accuracy, and weight. Both the currentity and reproducibility have reached the technical indicators stipulated by international authoritative organizations, and can meet the requirements for the detection of more than 200 kinds of veterinary drug residues in a variety of foods in China. The Expert Appraisal Committee recommends strengthening technical training and promotion of inspection and quarantine institutions and related personnel across the country.
It is reported that this research was started by a scientific research team led by Academician Pang Guofang of Qinhuangdao Inspection and Quarantine Bureau in 2002, with the purpose of cracking down on the technical barriers set abroad regarding the limits of veterinary drug residues in animal-derived products. In the study, Academician Pang Guofang presided over and organized a joint study involving more than 100 scientific and technical personnel from 12 inspection and quarantine bureaus including Hebei, Tianjin, Liaoning, Shandong, Shanghai, Guangdong, Fujian, Shenzhen, Inner Mongolia, Qinghai, Shenyang and Ningbo. . After more than 2 years of hard work, we have successfully developed a series of more than 200 kinds of veterinary drugs in 26 categories in the world that are suitable for different animal tissues and products such as puffer fish, eel, milk, milk powder, honey, royal jelly and various aquatic products. , Biological toxins, polycyclic aromatic hydrocarbons and other pollutant residues extraction, separation, enrichment and detection of new methods, and formed 91 national standard blueprints.
Charcoal grills are the most traditional choice for BBQ. Outdoor Charcoal BBQ Grilling takes us back to a simpler time, with people cooking over an open fire and bonding over good friends and delicious food.
While Gas BBQ grills may provide us with some of the same benefits, traditional Charcoal Grills add a genuine element to the grilling experience. How to choose the right Charcoal Smoker Grill and meet different consumers preference? Take the material, construction, grill size, temperature control, and cooking method into consideration.
