Role at Cawthron

Donato is an experienced analytical chemist who has specialised skills in the analysis of functional foods and pharmaceutical products, method development and validation.

He worked in the pharmaceutical industry in Italy for several years and has been a part of the research and development team at Cawthron for six years.

During this time Donato has developed and validated numerous analytical methods using a range of instrumentation, including:

  • liquid chromatography–mass spectrometry (LC-MS)
  • Gas chromatography–mass spectrometry (GC-MS)
  • high-performance liquid chromatography (HPLC).

He has worked on specialist projects that involved developing analytical methods for active compounds such as carotenoids, polyphenols and vitamins in food matrices and other biological samples. Donato has provided analytical testing support to several key New Zealand industries (including dairy and nutraceutical) and food safety regulators.

  • Familiar with the use of all major chromatographic instrumentation
  • Knowledge of US Food and Drug Administration (FDA), US Pharmacopeial Convention (USP) and EP regulations

Selected special achievements

  • Development and validation of an analytical method for simultaneous determination of fat soluble vitamins in food matrices by RP-HPLC and PDA-FLD detector. September 2006.
  • Development and GMP validation of an analytical method for the analysis of ascorbic acid in multivitamin/multimineral capsules. April 2006.
  • Development and validation to cGMP standards of an RP-HPLC method for determination of flavonoids in raw propoli and propoli extract. August 2007.
  • Development and validation of an LC-MS/MS method for simultaneous determination of water soluble vitamins (B1, B2, B3, B5, B6, B7 and B9 ) in food matrices. The method developed was validated and IANZ accredited. Cawthron report N. 1503. September 2008.
  • Development of an analytical method for extraction and determination of α-carotene and β-carotene in food matrices and nutraceuticals products by HPLC-PDA. March 2009.
  • Development of an analytical method for extraction and simultaneous determination of antioxidant compounds (Astaxanthin, Lutein, Canthaxanthin, β-carotene) in Haematococcus sp. algae and algae extract by RP-HPLC-PDA. April 2010.
