Hans Yates
Qualifications | Research interests | Publications | Memberships
Hans is currently the Senior Chemist in the Food Chemistry laboratory of Public and Environmental Health. He works closely with public and environmental health units throughout the state, analysing food and beverages for harmful toxins, allergens and contaminants, as well as ensuring that the nutritional value of the food is as claimed, and up to Australian Standards.
The laboratory makes use of GC/MS, HPIC, HPIC/MS, HPLC, FTIR, IRMS, liquid handling robot and other classical food analysis techniques to ensure that samples received are thoroughly and expertly tested.
Always on the look-out for interesting and new foods, Hans has been involved in determining the mystery of the purple orange and the purple noodles, and is currently testing insect and hemp based protein sources for nutritional value and food safety.
Hans is currently undertaking a PhD at the Queensland Alliance for Agriculture and Food Innovation, (QAAFI) University of Queensland. The focus of his research is building methods and testing capability for atypical sugars and amino acids in foods and beverage products.
