Simple and Rapid Method for the Quantification of Haloginated Dissaccharides (i.e. Sucralose) in an Aqueous Media
- Technology Benefits
- Fewer steps in comparison to traditional method, high throughput analysisLow volumeInexpensive
- Technology Application
- Rapid measurement of sucralose in solutionSolutions can be buffers, foods and beverages, as well as biological specimens including urine
- Detailed Technology Description
- Researchers at UC Santa Cruz have developed a chemical-fluorescent methodology to expedite quantification of sucralose in aqueous and biological solutions. This circumvents the HPLC-MS analytical challenge, which is labor intensive. The invention involves a quenched fluorescence-boronic acid based system to measure the sucralose derivative in a multi-well plate. The architecture of the quenched fluorescence system utilizes a boronic acid receptor molecule to detect cis diols present on the sucralose derivative.

- *Abstract
-
Sucralose is widely used as an artificial sweetener because of its low caloric content and is sweeter than table sugar (sucrose). Due to its resistance to metabolic degradation, sucralose can also be used as a marker for noninvasively evaluating the gastrointestinal small digestive tract (intestine) or colonic permeability. This urinary marker is traditionally analyzed by time consuming and expensive methods, such as high performance liquid chromatography coupled to mass spectrometry (HPLC-MS) or evaporative light scatter as the detectors. UCSC researchers have developed an alternative method using a chemical-fluorescent technique for rapid analysis of halogenated disaccharides, such as sucralose.
