) 1.014 chloride ≤ 10 (v / v) 0.315 grease ≤ 10 (m / m) 516 solution smell, taste and appearance inspection by 5.10 10 to 17 of evaporation residue (m / m) 1018 oxygen ≤ 10 (v / v) 3019 carbon monoxide ≤ 10 (v / v) 102O ammonia ≤ 10 (v / v) 2.521 phosphine ≤ 10 (v / v) 0.322 ≤ 10 for a hydrogen cyanide (v / v) 0.3 Note: The other oxygenated organic compounds, including dimethyl ether, ethylene oxide, acetone, isopropanol, is, iso-li Ji Ji Xing minced meat minced meat by the research: China will soon promulgate a new national standard coverage, test indicators, harmful impurities and so the same degree of control and reference the 1999 adoption of advanced foreign national standards and research to meet the beverage industry, carbon dioxide and other food basic requirements of product quality. In addition to its detection by chemical analysis of some indicators of value directly, the majority of indicators of the detection method used instrumental methods, the method value for money when you need reference material for comparison. The research is not yet available in China for food grade carbon dioxide product testing and analysis of a series of standard reference material, including: carbon dioxide as the substrate of nitric oxide, nitrogen dioxide, sulfur dioxide, carbonyl sulfide, methane, benzene, methanol, ethanol, acetaldehyde, dimethyl ether, ethylene oxide, acetone, isopropanol, is,tory burch shoes, isobutanol, ethyl acetate, amyl acetate, vinyl chloride,ugg milano, oxygen, carbon monoxide, ammonia and other gases the standard substance, Traceability and pass it exist defects. Lack of authority while the detection method and the equivalent detection methods. AI makes the neglect of the international quality assurance system of measurement and measurement traceability system. To evaluate the quality of domestic products in the series, Pepsi purchases in China are required of all food additives of carbon dioxide to the designated testing organization for testing. For example: Atlantic Analytical Laboratories Ltd (U.S.), Praxair Co., Ltd. Analysis Center Laboratory (U.S.), TNO Nutrition and Food Research Association (New Zealand), Praxair Co., Ltd. Thailand Praxair in analytical laboratory and so on. We know of our quality control testing and inspection of the validity of data through national measurement standards and measurement standards-based students in the effective line l on the basis of measured data can be guaranteed, so study the establishment of measurement standards so that our production of food grade carbon dioxide Enterprise products from raw materials source of gas to give effective control and monitoring of enterprises to improve productivity, reduce costs and make money according to the law of monitoring data plays an important role. Tracking international food measurement, metrological traceability of chemical development and the development of advanced analysis techniques should be measured before the domestic food market demand for reference material needed to study the establishment of an international quality standard components of the authority of the food carbon dioxide trace detection technology,ugg prezzo, testing methods and equivalent detection methods to the creation and study of reference materials for food grade carbon dioxide can be directly traceable to international units (sI) of the standard value, making it a high level to meet the social needs of the reference material. At the same time establish and improve the detection of food grade carbon dioxide value of traceability system to ensure the accuracy of testing data, validity and comparability of measurement is placed in the field personnel issues. Timely study of international quality standards of food grade carbon dioxide trace components, the authority of gas detection technology and measurement standards in the field of research on the upcoming implementation of new standards promulgated and strictly the good of the quality of food additives of carbon dioxide, a unified national test transmission standards and traceability system is a good opportunity, but also of the gas detected in the short term basis, an early detection method traceable to fundamental units, the basic ways in which the field of law. The perfection of the food supervision system, system of food safety, food industry as soon as possible to promote our access to international peer recognition and early into the international market, as soon as possible with the international imperative priority.
