Kangaroo meat - health secret revealed

23.04.2004


The meat of Australia’s bush kangaroo may be the highest known source of the healthy fat CLA, a University of Western Australia and CSIRO sponsored PhD student has discovered.



CLA (conjugated linoleic acid) is found in dairy products, beef and lamb.

In trials, CLA has been shown to possess potential anti-carcinogenic and anti-diabetes properties, in addition to reducing obesity and atherosclerosis (high blood pressure). PhD student Clare Engelke has found that the meat-fat of the Western Grey kangaroo in some circumstances has up to five times higher CLA content than lamb. "Australian pastoral lamb is considered to be a relatively high source of CLA, so I was surprised to find the levels in kangaroos were that much higher in comparison," Ms Engelke said.


Her study is believed to be the first research on CLA levels in kangaroos available in the public domain.

In collaboration with the University of Adelaide, Ms Engelke compared CLA levels in Western Grey kangaroos and lambs from the Badgingarra region in Western Australia and analysed tissue samples of other Western Greys, Red and Eastern Grey kangaroos from different areas of Australia. Although kangaroos are not a true ruminant, Ms Engelke became interested in researching Australia’s national icon for her PhD in agricultural science because, like ruminants, kangaroos ferment food in their foregut. CLA is produced in the stomach and tissues of ruminant animals such as sheep and cattle during the digestion process. In Australia, kangaroo meat has traditionally been used for pet food but the European market for the meat grew by 30 percent following the 2001 outbreak of foot and mouth disease.

CSIRO Project Leader Dr Andre Wright said kangaroo meat was very lean with a two per cent fat content. "Kangaroo meat also has high levels of protein, iron and zinc," Dr Wright said.

Ms Engelke is now working to identify the ’bugs’ in the kangaroo’s foregut responsible for producing CLA. "My aim is to find out which microorganisms and circumstances are responsible for CLA formation and why kangaroo meat appears to be the highest known source of these healthy fats," Ms Engelke said.

If successful, it may be possible to increase the CLA content of other meats and products to increase potential health benefits to consumers.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
