The two new types of human body can intake the standard substances of sugar in Guangdong Province

The reporter learned that recently, under the guidance of the Guangdong Provincial Market Supervision Bureau, the two new sucrose solutions newly developed by the Guangdong Provincial Metrical Institute, through national standards The technical expert committee organized by the expert office of the Material Committee was reviewed and was identified as a national second -level certificate of evidence. The standard value of the newly developed sucrose solution is 1.00%and 5.00%, and the expansion uncertainty is 0.01%and 0.05%, respectively, filling the vacancy of the low concentration value of the standard low concentration of the domestic sucrose solution.

It is understood that in recent years, due to the changes in health concepts, sugar -free and low -sugar foods are accepted by more consumers. Sucrose is an important food, sweet seasoning and preservatives. People are also attracting attention, but the existing standard substances of sucrose solution only include 10.0%, 30.0%, and 50.0%sucrose aquatic solution standard substances. Due to the lack of standard substances with concentration of less than 10.0%, the measurement result of the low concentration of sucrose value cannot be determined. Tracing, the results cannot be compared. The amount of sucrose of many sugar -free and low -sugar products is determined that it cannot be guaranteed.

On the basis of fully investigating the needs of economic and social development in Guangdong Province, the two newly developed low -concentration sucrose solution standard substances fill the vacancy of the low concentration value of the standard substance of the sucrose aquatic solution, helping this series of standards for this series of standards The material implementation concentration is fully covered, and further provides technical guarantees for the daily measurement of food safety sampling inspection monitoring, health and epidemic prevention and other departments in the analysis of the amount of sugar, and also provides a unified quantity standard for the various measurement departments of the national defense to ensure that the sugar measurement of the folding principle is as well The folder and other metering appliances are accurate and reliable.
