Holding a masters in nutrition sciences (Friedrich Schiller University, Jena, Gemany), Ms Nadine Macha (Hölzel) is a PhD candidate with the Tasmanian Institute of Agriculture, studying the effects of pre-harvest factors on nutritional and fruit quality parameters of sweet cherry with a focus on anthocyanins.

Biography

Nadine holds a masters in Nutrition Sciences (2009). Through her varied positions both in Australia and overseas she has gained solid, technical-based experience in analysis and consulting in the food industry, quality management, and research.

She held positions as Research Assistant at the Institute of Nutrition (Jena, Germany) and the Department of Biomolecular Chemistry of the Hans Knöll Institute (HKI, Jena, Germany) analysing secondary plant products.

In her role as Research Assistant at a laboratory service provider (Synlab Food), Nadine was the direct link between the Managing Director, the department managers and the customers, and was responsible for project management and evaluation, submission of daily test results and the supervision of diploma students and interns.

Expertise

  • Nutrition sciences
  • Nitrogen use in commercial cherry orchards
  • Cherry fruit quality assessment
  • Anthocyanins in cherries

Research Themes

Nadine’s research aligns to two of the University’s research themes, i.e. ‘Environment, Resources and Sustainability’ and ‘Better Health’. Her research is linked to the ‘More Profit from Nitrogen’ Program and aims to improve cherry fruit quality through more efficient use of nitrogen fertilisers. She also investigates the red pigments in cherry fruit, called anthocyanins, which may play a therapeutic role in human disease.

Collaboration

Nadine is involved in the ‘More Profit from Nitrogen’ Program, which is managed by Cotton Research & Development Corporation (CRDC) in partnership with Dairy Australia, Sugar Research Australia and Horticulture Innovation Australia.

Current projects

PhD project: ‘Optimising Nutrient Management for Improved Productivity and Fruit Quality in Cherries.’

This project aims to develop nutrient management strategies in order to achieve improved yield and fruit quality of sweet cherry crops in commercial orchards. Addressing the increasing consumer awareness of health benefits associated with cherry consumption, special focus is laid on evaluating how pre-harvest factors affect the profile, content and stability of anthocyanins, a group of compounds associated with cherry colour and bioactive affects.

Key objectives of this project address the main research question: “How do different nitrogen fertiliser applications impact on fruit quality and nutritive properties of sweet cherries?”

They include:

  1. Evaluation of the effects of fertiliser type, rate and application timing on fruit quality.
  2. Identification and evaluation of foliar nutrient application options to improve fruit quality.
  3. Evaluation of the influence of pre-harvest factors on anthocyanin profile, content and degradation in cherries.
  4. Determination of anthocyanins and metabolites in human biological specimen after cherry consumption.
