Unlocking the Power of Potato Starch with Expert Analysis

With advanced technology and extensive experience in the field of Pharmaceutical Excipient Analysis, CD BioGlyco provides clients with a comprehensive potato starch analysis service. Potato starch is a starch extracted from potatoes and usually contains large oval spherical granules of 5 to 100 μm in size. Potato starch is also used as a pharmaceutical excipient in oral formulations and can be used to develop diluents, disintegrants, binders, and so on.

• Identification
  Under the microscope, potato starch appears as transparent, colorless granules. It usually presents an irregular shape (ovoid, pear-shaped, or round) and its diameter ranges from 30 μm to 100 μm.
  In addition, potato starch particles exhibit characteristic dark crosses in polarised light.
• pH
  Potato starch is dissolved in water and its pH is checked using a pH meter. The pH of potato starch should be 5.0 to 8.0.
• Sulfur dioxide content
  Acid-base titration: Potato starch solution is titrated using ethanol solution of methyl red as indicator and sodium hydroxide solution as titrant. The sulfur dioxide content is calculated from the amount of sodium hydroxide used.
• Oxidized substance content
  We titrate the potato starch solution with sodium thiosulfate solution as titrant. When the color of the solution fades, the titration is stopped. The amount of oxidized material in potato starch is calculated based on the amount of sodium thiosulphate used.
• Loss on drying
  Potato starch is left to dry at high temperatures. It must not lose more than 20.0% of its weight.
• Scorch residue
  The residue of potato starch left after thorough scorching shall not exceed 0.6% by weight.
• Iron salt assay
  Dilute hydrochloric acid, ammonium persulphate, and ammonium thiocyanate are added to a solution of potato starch and compared with a standard iron solution. If the colors of the two solutions are the same, it proves that iron salts are present in the potato starch.
• Heavy metal detection
  We offer the detection of metal elements in potato starch.
• Microbiological limit
  The microbial enumeration method is used to detect the number of thermophilic bacteria and fungi in potato starch under aerobic conditions. Specific microbial enumeration methods include the flat dish method, membrane filtration method, and the most-probable-number method (MPN method).
  In potato starch, the total number of molds and yeasts must not exceed 10² cfu and Escherichia coli is not present.
