Australasian Section, American Oil Chemists’ Society
December 2016, Newsletter
From the President Hello,
Another year has flown by. On behalf of the Australasian Section Committee, I
would like to wish all members and colleagues a safe and happy Christmas and a
prosperous new year.
From the AAOCS, I would like you all to mark down Sept 11-13 in your diaries as
the next and 10th AAOCS conference. It will be in the beautiful Barossa Valley, SA in
a Chateau (see pic). We are hoping to deliver a great/memorable experience along
with high quality scientific and industry relevant presentations. The next theme is
“Biotechnology, lipidomics and nutrition” and has some high quality keynote
speakers to cover those topics
(including Prof Kent Chapman,
University of North Texas on
biotechnology and Associate
Professor Peter Meikle (Baker IDI)
who leads the Metabolism Program
and is Head of the Metabolomics
Laboratory). So please save these
dates, prepare an abstract/talk, invite
your friends/colleagues, and join us for the 2017 AAOCS meeting. There might even
be some wine tastings. https://aaocs2017.wordpress.com/
The AAOCS recently helped to organise and support the 2016 NZ fats and oils
conference in Nelson NZ. This was a wonderful event with some very high quality
presentations and some great discussions. We would like to thank Laurence Eyres
who was the driving force for this conference. Please see article below for more
information.
Personally, I have had an amazing year. I have seen some amazing science (and
people) in a trip to Japan, and my second child, Hazel Marie, arriving in August was
probably the big highlight.
Again we wish you a safe and happy Christmas.
Matt Miller

Science of Omega-3: Balancing the Scales Omega-3 Centre – Complimentary Medicines Australia: Joint Symposium Peter Nichols, CSIRO
The joint Science of Omega-3 symposium was held at Doltone House, Sydney on
September 14, 2016. The symposium brought together national and international
experts with the overall aim being to update about 100 attendees on a suite of new
developments in the Omega-3 field. In addition to the excellent presentations on the
day, robust discussion across a range of topics occurred after all talks. The omega-3
field in Australia and New Zealand is clearly well placed with much good science
underway, and will continue to be at the forefront of international advancements.
An overview of the topics discussed can be found online (PDF). The topics
discussed included:
� The global omega-3 market: a look at the numbers and the consumer (Ellen
Schutt – GOED)
� Omega-3 fatty acids – potential use in the treatment of unipolar and bipolar
depression (Jerome Harris – University of Melbourne).
� Divergent shifts in lipid mediator profile following supplementation in n-3
docosapentaenoic acid and eicosapentaenoic acid (Andy Sinclair – Deakin
University)
� The place of omega-3 in cardiovascular disease prevention (Ross Walker –
Cardiologist and author)
� The Omega-3 Index - the standard for omega-3 status testing (William Harris
– University of South Dakota)
� DHA and Infant health (Barbara Meyer – University of Wollongong)
� Australian and NZ fish oil – an update on current and future sources of long-
chain omega-3 oils and their quality (Peter Nichols – CSIRO)
� Utilising innovative fishing technology to investigate the oil and fatty acid
composition of Antarctic krill (Patti Virtue – University of Tasmania)

Lipids, Nutraceuticals and Healthy Diets throughout the Life Cycle conference
Matt Miller, Cawthron Institute
The conference, which took place from 8-10th November, was deemed a great
success by all who attended. The mixer and opening took place in bright sunshine at
the renowned Cawthron Institute. They organised a great mixer and Professor
Charles Eason, the head of the Institute gave a short speech of welcome and
opened the conference. The next day, Harvey Ruru gave a heart-warming Mihi,
which to this author was one of the highlights and kicked off the day to a great start.
Dr. Matt Miller of the Cawthron proved an enthusiastic and super-efficient chairman
of the conference with Kerry South (the event coordinator) making sure everything
ran smoothly.
On the main day of the conference 20 speakers gave excellent presentations. For
those attending (136) we hope to be able to make the presentations available on the
website.
The student poster prize was won by Mr. Shuo Yang of Massey University. This
consisted of a cash prize and the opportunity to attend the AAOCS conference in
2017. His topic was around the production of avocado oil. This is a continuation of a
research topic pursued by Professor Wong and Allan Woolf for over 15 years with
several books and papers published in International scientific media.
The final day saw a stimulating half-day seminar on marine bioactive compounds
and it is hoped that the papers from this meeting will become available on
http://www.oilsfats.org.nz/2016-conference/ .
Nelson proved to be a great place for a conference with everything within walking
distance, good food, pleasant shopping areas and boutique beers.
Some highlights on nutrition and recent controversies (saturated fat and omega-3
PUFA) taken from the papers by Professors Calder and Clifton were:
� Replacing 5% of energy from saturated fats with equivalent energy from
PUFA and MUFA is associated with estimated reductions in total mortality of
27% and 13% respectively
� ALA, DPA, and DHA intakes were associated with a lower risk of fatal CHD
� Intake and status of marine w3 fatty acids can be markedly increased through
intake of oily fish or supplements
� Much is known about patterns of incorporation of EPA and DHA in humans
5
� EPA and DHA act through multiple, increasingly understood, molecular and
cellular mechanisms to affect cell and tissue function
� Through these actions marine w3 fatty acids act to promote and maintain
health and to reduce disease risk
� Marine w3 fatty acids are important throughout the life course
� There is robust evidence that long-term intake of marine w3 fatty acids
reduces risk of coronary heart disease – due to beneficial impacts on a range
of risk factors
Australian and New Zealand Fish Oils – New Study Published in Nutrients Peter Nichols, CSIRO
Over the past 2 years several papers from the Liggins Institute/University of
Auckland and collaborators have been published questioning the quality of
Australian and New Zealand (ANZ) fish oil products. Considerable negative media
followed. The authors stated that products did not meet label omega 3 content
claims and were heavily oxidized. AAOCS readers have seen various updates from
the ANZ Omega-3 Centre (O3C) over this period. In November the results for
independent analyses commissioned by the O3C were published in Nutrients -
http://www.mdpi.com/2072-6643/8/11/703. The results were also presented at the
two conferences summarized above. The Nutrients paper clearly showed that ANZ
fish oils, when analysed by certified and Therapeutic Goods Administration
approved laboratories, are not oxidized and do meet their omega 3 label claims.
Australian and New Zealand Fish Oil Products in 2016 Meet Label Omega-3 Claims and Are Not Oxidized Abstract: We provide new fish oil product results to assist industry in Australia and New Zealand and, ultimately, consumers in understanding the high product quality assurance protocols in place, together with the high product quality that has been determined by both industry and independent laboratories. Fish oil capsule products common to Australia and New Zealand were purchased in May 2016 in Richmond, Victoria, Australia. Products were from two groups; five standard fish oil products and five fish oil concentrates. Noting Therapeutic Goods Administration (TGA) requirement for use of standard methods, for all analyses undertaken a laboratory was selected that met the TGA criteria, including with accreditation. Total n-3 content exceeded the label-claimed content for all 10 products, with supplements containing on average 124% of the claimed content (range 115%–136%); eicosapentaenoic acid and docosahexaenoic acid (EPA + DHA) content averaged 109% of the label claim (range 99%–119%). All 10 products (100%) similarly met the international recommended peroxide value (PV) level. Anisidine value (pAV) met the international recommended level for eight of the 10 products, with two products known to contain
6
flavourings that interfere with the pAV test. When accredited laboratories and standard protocols are used, Australian and New Zealand fish oil products have been shown to clearly meet their label claims for EPA + DHA content, and are not oxidized.
The Nutrients paper has been circulated to a range of societies and other outlets and
the AAOCS section committee has discussed and endorsed the statements of the
ANZ O3C.
UQ’s algae pilot is about to expand into commercial output Geoff Wilson, Director, Qponics Limited
The University of Queensland’s algae production pilot plant is about to become a
new model for low-cost but state-of-the-art commercial raceway algae farms around
the world.
Qponics Limited is an Australian start-up company which is preparing to
commercialise UQ-developed technology. It is planning to construct an algae farm
near Brisbane to produce human food ingredients – namely EPA omega-3 oil and
high-quality algal protein. First sales are expected during the 2017-18 financial year.
R&D from staff and students at UQ led by Professor Peer Schenk, has resulted
in more productive open and closed pond systems for growing and harvesting many
different species of algae. Qponics has chosen to begin with a Queensland strain of
Nannochloropsis – which is a local species of algae the university has optimised to
produce nearly 40% of omega-3 (EPA) in its fatty acids.
UQ has collected numerous species of algae over a number of years and several
of these have shown commercial value for production of nutraceutical and food
supplement products that are of interest to Qponics. Dr Graeme Barnett, CEO of
Qponics Limited said: “Over the last five years Qponics has reviewed algae
production technology from more than 60 overseas suppliers. Unfortunately, all were
found to be too expensive and not suited for algae farming in south-east
Queensland.
“Professor Schenk delighted us in February 2016 when he showed the Company
the latest productivity data from his research Algae Energy Farm at Pinjarra Hills in
Brisbane. UQ’s outdoor and covered raceway pond systems were subsequently
adopted by Qponics, and we were successful in winning a Cooperative Research
7
Centres Project (CRC-P) grant in June 2016 with the support of UQ to build our first
algae farm.”
While Qponics is initially focused on the production of omega-3 oil for the human
food supplement market, especially in Asia, the algae farm will also produce high-
protein algal biomass.

AAOCS membership in focus
AAOCS is looking at ways to better foster communication and collaboration within
the section. As an effort to highlight the diverse nature of our membership and to
promote interaction between our section members, we will give a brief insight into
members of the section and what they do. In this newsletter, we present our student
representative Clare Flakelar.
Clare Flakelar is a PhD student with Charles
Sturt University, Wagga Wagga, under the
supervision of A/Prof Paul Prenzler. Her
research is looking at enhancing canola quality
through examining levels of tocopherols,
carotenoids and phytosterols in canola seed
and oil. The work includes monitoring effects on
these bioactive compounds from: seed growth and development, storage
11
techniques, and commercial processing. The results will provide information into
potential value-adding for the canola seed and oil industry. Clare’s project is funded
by the Grains Research Development Corporation (GRDC), and the Graham Centre
for Agricultural Innovation (a joint collaboration between Charles Sturt University and
Department of Primary Industries). So far, the research has been presented at seven
national and two international conferences, including directly to industry at the
Australian Oilseeds Federation Annual General Meeting, and resulted in two
publications. Clare is preparing her thesis for submission in 2017.
