Oxystarch Analysis Service

Explore Unlimited Possibilities with Oxystarch Analysis

Oxystarch is the product of corn starch that produces two aldehyde groups on each monomer after oxidation by sodium periodate. Upon oxidation, the internal polysaccharide chains of starch are fragmented and the crystalline layer of starch granules changes with it. As a result, the thermal and pasting properties, swelling capacity, solubility, and sensitivity of oxidized starch are changing. The dialdehyde group of oxystarch is widely used because of its high reactivity. We provide Pharmaceutical and Biological Analysis to our clients using reliable and advanced analysis. At CD BioGlyco, we offer high-quality oxystarch analytical services from a variety of perspectives.

CD BioGlyco has a professional analysis team providing the following oxystarch analysis service.

  • Fundamental analysis
    Our experienced researchers provide you with fast, accurate analytical services including:
    • Free starch
    • Loss on drying
    • Swelling power
    • Pasting property
    • Iodide
    • Ignited residue
    • Solubility
    • Differential scanning calorimetry (DSC)
    • Acidity
    • Heavy metal
    • Gelatinization property
  • Molecular structure analysis
    • Morphology
      We analyze the shape of oxystarch by scanning electron microscopy (SEM) and use transmission electron microscopy (TEM) and atomic force microscopy (AFM) to characterize the surface and internal crystal ultrastructure of starch granules.
    • Crystallinity and polymorphic composition
      Starch crystallinity is affected by factors such as crystal size, branched chain length, and branched starch content. In general, the oxidation process has less effect on the crystallinity. We analyze the crystallinity of oxystarch by characterizing the changes in semicrystalline and amorphous structural domains within oxystarch particles by Fourier-transform infrared spectroscopy (FTIR).
    • Oxidability, molecular weight, and degree of polymerization (DP)
      Our researchers analyze the degree of oxidation of oxystarch mainly by glyoxalate analysis and nuclear magnetic resonance (NMR) analysis. Moreover, we analyze the molecular structure of oxystarch with the help of gel permeation chromatography (GPC) and high-performance size exclusion chromatography (HPSEC).

Publication Data

Technology: HPSEC, X-ray diffractometry, UV-vis spectrophotometer

Journal: Carbohydrate Polymers

Published: 2006

IF: 10.723

Results: The researchers evaluated the X-ray diffraction patterns of periodate-oxidized starch, the molecular weights of starch polysaccharide molecules, the length distribution of branched amylose side chains, and the iodine-binding properties of starch polysaccharides. The results showed that the polysaccharide molecules were gradually fragmented during starch oxidation. The molecular molecular weight and radii of gyration depended on the degree of oxidation, and the average molecular weight of the most oxidized dialdehyde starch was less than 1×104.
