Oligofructose/Food Parameter Detection

Related physical standards: Oligofructose is formed by the aggregation of 2-10 identical or different monosaccharides, with different sites and lengths of sugar chain aggregation, resulting in different isomers and complexity of composition. Especially with the presence of structurally similar isomers, it is difficult to further separate and purify. In addition, many effective ingredients lack spectral sensitive molecular structures themselves, and conventional analysis methods cannot meet the requirements for separation and detection of each component, making detection difficult. More importantly, due to the lack of high-purity standards for different isomeric monomers as reference materials for testing, there has been a lack of unified and direct testing methods worldwide, resulting in significant differences and controversies in the testing conducted by different countries, enterprises, and even individuals. This has brought many difficulties to the promotion and application of oligofructose. In addition, only a few foreign companies produce oligofructose standards, Domestic imports are still needed and the prices are very expensive. New sugarcane fructose and isosugarcane fructose are isomers of sugarcane fructose, and there are no companies internationally capable of producing them&Nbsp; In order to solve the bottleneck problem that restricts the quality evaluation and international market promotion of oligofructose products, the Shandong Provincial Analysis and Testing Center under the Shandong Academy of Sciences, as a technical support unit, jointly applied for the "Development of Six National Standard Samples of Oligofructose" project with a certain company in early 2013. Through two years of joint research and production, the project successfully passed the expert review and review of the National Standard Sample Committee at the end of 2014 Confirm and obtain the national standard sample certificate&Nbsp; The release of six high-purity national standard samples, including Sugarcane Trisaccharide, Isofructose Trisaccharide, Sugarcane Trisaccharide, Sugarcane Tetrasaccharide, Sugarcane Pentose, and Sugarcane Hexasaccharide, fills multiple gaps in physical standards at home and abroad, and will help solve the problem of detecting oligofructose, form standardized, unified, and direct oligofructose detection methods, and further promote the promotion and application of oligofructose&Nbsp; In the international standard system, standards include written standards for quality measurement methods and physical standards for active ingredients, which are combined to form a complete standard form. Text standards mainly refer to the textual norms of quality indicators and analysis methods, such as common enterprise standards, industry standards, national standards, etc. Their function is like the "standard scale" for analyzing specific products, while physical standards are the "weight" of text standards. Only by using physical standards as a benchmark can text standards have accurate reference standards and achieve precise and repeatable detection and analysis in different time and space occasions and on different detection equipment. In the history of our country, books and vehicles have been on the same track, and modern inspection instruments have been used as benchmark reference materials, all of which reflect the important role of physical standards. Physical standards and written standards complement and support each other&Nbsp; In 2015, a national standard drafting working group meeting for oligofructose and inulin was held in Jiangmen City, Guangdong Province, led by the China Food Fermentation Industry Research Institute and co organized by a certain biotechnology company. The meeting revised GB/T 23528-2009 "Oligofructose" and also initiated the drafting of national standards for inulin&Nbsp; The earliest regulations on oligofructose in China can be traced back to the industry standard "General Technical Rules for Functional Oligosaccharides" issued by the Ministry of Light Industry in 1990; In 1997, the General Standard for Health (Functional) Foods (GB 16740-1997) issued by the National Bureau of Technical Supervision was implemented, which clarified that oligofructose can be used as a food ingredient in health foods; In 2006, the Ministry of Health approved oligofructose as a new resource food. With the deepening of research on oligofructose and the expansion of its application, in 2009, the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China issued GB/T 23528-2009 "Oligofructose"&Nbsp; However, in recent years, the oligofructose industry has developed rapidly, and its production process, quality, yield, and market application have undergone significant changes. The existing national standards need to be further revised. This national standard revision meeting mainly addressed the definition of oligofructose from different raw materials. As an internationally recognized prebiotic oligofructose (FOS), inulin is also an important source of raw material in addition to sucrose. Due to differences in raw materials and process technology, there are differences in structure, degree of polymerization (chain length), and other aspects between the two, which need to be further clarified in the national standard. The meeting also discussed the standards and testing methods of oligofructose, and made revisions to some physicochemical and safety indicators in accordance with the requirements of the Food Safety Law of the People's Republic of China&Nbsp
