Glucose is the most abundant monosaccharide and contained in many foodstuffs naturally or added as an ingredient.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Objective<\/jats:title>\n                  <jats:p>To validate the performance of the Enzytec\u2122 Liquid Combi Sucrose\/D-Glucose test kit for the determination of sucrose and D-glucose in juices, chocolate, breakfast cereals, ice cream, sweetened condensed milk, wine, beer, and soft drinks.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>The kit contains all reagents in a ready-to-use format and is suitable for automation. Sucrose is cleaved by \u03b2-fructosidase. The resulting D-glucose from sucrose and glucose originally in the sample are phosphorylated and react in a NADH-generating reaction afterwards. \u03b2-Fructosidase is not present in the glucose system. The amount of NADH produced is equivalent to the amounts of sucrose and D-glucose and is measured at 340\u2009nm within 30\u2009min.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>The linear measurement range for a 100\u2009\u00b5L test volume is from 17 to 2500\u2009mg\/L sucrose and 4 to 2000\u2009mg\/L D-glucose. Trueness was checked by using four Certified Reference Materials (CRM) and resulted in recoveries from 96 to 105%. Spiking of juices, ice cream, sweetened condensed milk, and shandy resulted in recoveries between 98 and 106% for both systems. Intermediate precision was 3% or lower for sucrose and glucose. For automation, three applications with different test volumes were validated. Linearity is given from 3.8 to 9500\u2009mg\/L for sucrose and 2.4 up to 10000\u2009mg\/L for glucose.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>The method is robust and accurate for manual and automated applications.
