From the President
Hello everyone and welcome to the first newsletter for 2014. Despite the committee’s quietness we have been thinking/working hard behind the scenes in planning the next section meeting together with short courses for November 2015. It is not that far away, so if you have any ideas, in particular around short course or keynote speakers that you would like to see at our next meeting, please get in contact with me (firstname.lastname@example.org).
It is very pleasing to see some of our members and former members are getting the recognitions worldwide and locally. Rod Mailer and Ian Purtle were awarded as AOCS fellows at the recent meeting in San Antonio, Andrew Sinclair will be the next recipient of “The Alexander Leaf Distinguished Scientist Award for Lifetime Achievement” at ISSFAL 2014, Cobram Estate cleaned up at the New York International Olive Oil Competition and SeaDragon Marine Oils was winner of exporter of the year from Natural Products NZ. Well done to all of you.
A big congratulation to Karen Dutch (nee Murphy) (ex AAOCS president) on her third little baby, Bethany Rose Dutch (weighing in at 3.59kg), born Tuesday 4-March-14 at 1.16pm. We hope all is going well.
A special edition of the journal Nutrients called “Recent Advances in Omega-3: Health Benefits, Sources, Products and Bioavailability” has been put together from the AAOCS 2013 meeting (see below). I would like to thank Peter Nichols for driving this special edition.
President, Australasian Section
Update on the AAOCS-O3C Nutrients Special Issue:
The Nutrients Special Issue arising from the November joint AAOCS section meeting and The Omega-3 Centre is progressing. Five papers are now published, and a further 7 manuscripts are all submitted and under journal review. One of the 7 manuscripts under review will provide an overview of all papers arising in the Special Issue from the Omega-3 Symposium (Recent Advances in Omega-3: Health Benefits, Sources, Products and Bioavailability). Additionally this overview article aims to cover the recent round of negative media that has been directed to Omega-3 oil products. Print copies of the Special Issue will be available for purchase once all papers have been finalised. Special issue link here.
Australia’s olive oil a cut above the rest
Cobram Estate is Australia’s top olive oil producer after winning five international gold medals at the recent New York International Olive Oil Competition. The five medals included two ‘best in class.’ Competition included more than 700 extra virgin oils from around the globe. Click here to read more.
Flaxseed fibre – Review
Dr. Laurence Eyres (FNZIFST) and Mike Eyres (BV&O) have recently reviewed the nutritional and culinary uses of flaxseed (linseed) in an article ‘Flaxseed (Linseed) fibre – nutritional and culinary uses – a review,’ published in the Food NZ magazine. The article provides an introductory level overview of what flaxseed fibre is, its biochemical composition, nutritional content and associated health benefits, as well as its uses in culinary settings. A useful read for anyone interested in learning more about this material.

Australia’s first fresh-water algal omega-3 oil is now under test
Algae researchers at the University of Queensland have supplied the first samples of omega-3 oil, produced from fresh-water tolerant algae, to Qponics Limited for commercial testing. It represents a critical R&D step for Qponics Limited, a 3 year old Brisbane-based company which aims to be a global leader in the production of “organic” omega-3 oils using a suite of new technologies in an urban agricultural setting.
In 2011 Qponics signed agreements with UQ’s UniQuest Pty Ltd. This gave the company access to UQ’s extensive algae collection for a defined research and development project. The agreement also covered the scientific services of the University’s Professor Peer Schenk, who is a global leader in the biotechnology of algae and algae oil. In 2012, Qponics signed a heads of agreement with UniQuest on the terms to license strains of algae for the commercial production of omega-3 oils and high-protein biomass.
Dr. Graeme Barnett, CEO and Managing Director of Qponics Limited, said: “Our Company aims to sell organically-produced DHA and EPA omega-3 oils to a wider segment of the global market. This will present a more viable option to companies that use omega-3 in their products and to consumers of these products. Both are looking for sustainably-produced vegetarian alternatives to products derived from fish, krill or other marine animals.
Algal biomass remaining after oil extraction will be sold as a high-protein human food or animal feed containing residual DHA and EPA omega-3 oils. Qponics also has an option to extend the license to other non-biofuel algal-derived products for the strains developed under the 2011 agreement.”
Qponics plans to construct its first commercial plant on a site near Sydney. This unique facility will integrate state-of-the art technologies used to cultivate algae and extract their omega-3 rich oils into an existing sustainable aquaculture-horticulture process, where filtered effluent from fish tanks provides the organic nutrients to fertilise the growth of algae.

Oilseed-like levels of TAG in leaves
A recent publication ‘Metabolic engineering of biomass for high energy density: oilseed-like triacylglycerol yields from plant leaves’ in the Plant Biotechnology Journal demonstrates progress made in increasing the TAG content of leaf material. Dr. Surinder P. Singh (Group Leader of the Oilseeds Group, CSIRO) outlines the article below.
High biomass crops have recently attracted significant attention as an alternative platform for the renewable production of high energy lipids such as triacylglycerol (TAG). While TAG typically accumulates in seeds, levels in vegetative/leaf tissues are generally low. The publication reports the accumulation of more than 15% TAG (17.7% total lipids) by dry weight in Nicotiana tabacum (tobacco) leaves. This was achieved by the coexpression of three genes involved in different aspects of TAG production without severely impacting plant development. These yields far exceed the levels found in wild-type leaf tissue as well as previously reported engineered TAG yields in vegetative tissues of Arabidopsis thaliana and N. tabacum. When translated to a high biomass crop, the current levels would translate to an oil yield per hectare that exceeds those of most cultivated oilseed crops. Our results demonstrate the technical feasibility of a vegetative plant oil production platform and provide for a step change in the bioenergy landscape. This research opens up new prospects for sustainable food, high energy forage, biofuel and biomaterial applications.

Seadragon – Top exporter award and future refining factory
Seadragon was recently awarded the DHL Global Forwarding Exporter of the Year award at the recent Natural Products NZ summit. The award recognised the companies unique product propositions, its ability to commercialise resources that would otherwise have been wasted and the impressive growth of the company. CEO Ross Keeley said “This award shows we are well positioned as we prepare to expand our Omega-3 fish oil production capabilities.”
Seadragon’s omega-3 production capacity is to be extended with plans for a new refining factory. Construction of the factory is set to begin later this year, with production commencing in the first half of 2015. The factory will be used to refine omega-3-containing oils from hoki, salmon, tuna and anchovies. For more information click here.
The effect of a Mediterranean diet on cognitive performance and cardiovascular health in healthy Australians aged 65 years and above
Earlier this year Dr. Karen Dutch made an appearance on Channel 9 news (clip here) regarding the Mediterranean diet and its potential benefits. Karen outlines this work below.
Diet is the cornerstone in reducing the risk of chronic diseases and there is growing interest in investigating the effect of whole dietary patterns (rather than individual foods or nutrients) on cognitive function and the risk of one of the most prevalent forms of dementia, Alzheimer’s disease. The Mediterranean Diet (MedDiet) contains nutrients which have individually been shown to benefit cognitive function as well as promote longevity and reduce death from heart disease.
The MedDiet consists of a range of foods such as fruits, vegetables, legumes and nuts, olive oil, low fat dairy foods, fish, lean meat and red wine. This diet delivers important bioactive nutrients like omega-3 and monounsaturated fatty acids as well as antioxidants, fibre, vitamins and minerals. The diet is thought to have a protective effect through a number of ways including reduced inflammatory markers and counteracting inflammatory processes that occur with cognitive decline including reducing the accumulation of brain plaques which lead to generalised neuroinflammation, improved brain blood flow and reduced oxidative damage. The MedDiet may also have direct effects on brain physiology or may influence cognition more indirectly through improved cardiovascular health.
At present, population and interventional trial evidence from outside of Australia indicate the potential for beneficial effects of the MedDiet pattern on cognition, reduced risk of Mild Cognitive Impairment and Alzheimer’s disease. There is little data on the effect of a Mediterranean diet in Australians. Therefore the Nutritional Physiology Research Centre, at the University of South Australia with funding from the National Health and Medical Research Council are further investigating the effect of a MedDiet on cognitive performance and cardiovascular health in the local population.
The study will enrol a total of 170 volunteers, who are non-smokers, free of dementia and aged 65 years and above. Half of the volunteers will be allocated a MedDiet pattern, while the other half will be asked to maintain their normal diet for 6 months. Volunteers will have a range of cognitive tests and cardiovascular health measurements (blood cholesterol, glucose, inflammatory markers, blood pressure and blood vessel function) performed at the beginning of the study and again at 3 and 6 months. All volunteers will visit with the dietitian fortnightly to check how they are going with the study and to collect supplied study foods throughout the trial.
We believe that following a Mediterranean dietary pattern for 6 months will improve cognitive performance (i.e. memory, thinking) and cardiovascular health (i.e. blood pressure and blood vessel function) which addresses the National Research Priority: Ageing Well, Ageing Productively, Preventative Health Care and Mental Health.
