Dr Jaspreet Singh
Research Officer
Food science and nutrition
Place of Work
Riddet Institute

Jaspreet’s research currently focuses on characterising food crops, like cereals and potatoes. He characterises these resources to help develop new, custom food products. Jaspreet enjoys his research and thinks food products are a new, interesting field with lots of unsolved problems.


Jaspreet leads several research projects at the Riddet Institute. He has recently characterised taewa (Māori potatoes) and kamokamo (Māori pumpkin). He found that taewa have high levels of protein, essential amino acids and antioxidants. Using this knowledge, he has looked at developing new food products from taewa, like crispy snacks and chef-ready potatoes.

Food products are an exciting area with lots of new, interesting and unsolved problems.  

Get focus story: Taewa (Māori potatoes)

Starches from cereals and potatoes are important raw materials for the food industry and other industries. Jaspreet examines starch spherulites (tiny crystals formed during heating and rapid cooling of starch) by using techniques like electron microscopy, X-ray diffraction and thermal analysis.

Collaboration is a key part of Jaspreet’s research. He works with food chemists, engineers, nutritionists and the food industry. His research helps develop new processing technologies, healthier food products and can solve food processing problems.

Career pathway

Jaspreet joined a research team at Massey University in 2004. He now leads several research projects at the Riddet Institute and supervises graduate, post-graduate and visiting students.

Jaspreet has travelled a lot with his job. Before joining the Riddet Institute, he worked as a post-doctoral researcher at Kansas State University in the United States and the Institut National de la Recherche Agronomique (INRA) in France. Jaspreet’s PhD helped the food industry make better use of cereals and vegetables during food processing.

It is important to share your research with others, and Jaspreet has published research papers in international journals, written book chapters and presented his work at international conferences. Also, Jaspreet recently edited a 600-page book entitled Advances in Potato Chemistry and Technology, which will be published by Elsevier/Academic Press, USA.

In 2006, Jaspreet was presented with a College Research Award – Early Career from Massey University in recognition of his research.

Personal interests

Jaspreet enjoys spending time with his wife, listening to classical music, walking, reading and understanding different cultures, and visiting museums and art galleries.
