General description

D-Panose belongs to the class of oligosaccharides, found to be mildly sweet. It is composed of 1–4 and 1–6 linkages in its structure. Its potential as a prebiotic candidate in pure culture and colon simulator utilizing the complex fecal microbiota is investigated. It is reported as a component present in Chinese rice wine, and also exists as an important bioactive constituent of various types of honey.

Application

D-Panose may be used as an analytical standard in the following:     
  • analysis of the analyte in spiked aqueous samples using magnesium oxide nanoparticles (MgO-NPs) as a matrix followed by surface-assisted laser desorption-ionization time-of-flight mass spectrometry (SALDI-MS). This technique can be further applied for the analysis of the analyte in the low-mass region
  • determination of the analyte in Chinese rice wine using Fourier transform mid-infrared spectroscopy (FT-MIR)
  • determination of the analyte in adulterated commercial sweet sorghum syrup using ion chromatography with integrated pulsed amperometric detection (IC-IPAD)- sodium hydroxide (NaOH)/sodium acetate (NaOAc) gradient method
