My research as a gateway to travel, to knowledge wonderland, and self-improvement
By: Sihui Lang
Three years ago, I started preparing
to apply to Chapman University’s Food Science Program. At that time, I never
imagined that three year later, I would have three scientific published papers
and attend three scientific meetings seen below!
AOCS Annual Meeting & Expo 2017
IFT Annual Meeting 2017
AOCS Annual Meeting & Expo 2018
This year, American
Oil Chemists’ Society (AOCS) Annual Meeting and Expo 2018 was held in Minneapolis,
MN. AOCS mainly focuses on the science and technology of oils, fats, proteins,
surfactants and other related materials, which tied well with my research on protein
and phenol oxidation interactions: chlorogenic acid covalently bonds with amino
groups to form green pigments in sunflower butter cookies when we add baking
soda. During the Annual Meeting and Expo, there were more than 1,600 attendees
and about 500 different presentations and posters on novel technologies and
science information on lipid and protein extraction, purification, processing,
or application. This year, I was most interested in and attended the speeches
or looked for the posters of functions of oilseeds and protein (mainly about
pulse protein) and new methods in using of oil and proteins.
There were so many interesting topics, for example,
I. Nutrition: the
application of medium-chain triglycerides/ MCT oil on Alzheimer's and
Parkinson’s diseases and the need for more studies to determine if MCT oil
could prevent Alzheimer's and Parkinson’s diseases.
II. Protein
products on application of pulse protein to mimic the texture of real meat such
as chicken; application of insect protein or oil in food products; establishing
novel emulsions using pulse protein or starch; using by products from
extraction or purification as biofuel and using potato peptides as antioxidant
in food products, etc.
When I took research methods in 2016,
I chose my lay audience topic on mango kernel oil, which is rich in
Triglyceride to replace or make oil blends to prevent the blooming of chocolate
at room temperature. Coincidentally, during the AOCS meeting, there was an oral
presentation on Preparation of Mango
Kernel fat stearin using 2-methylpentane and its application in heat-resistant
chocolate fats. Instead of a theorical hypothesis, the presenters were
trying to use it in production of the real world. Additionally, our 2017 FSNSA
president Tara Okuma had a topic on CRISPR-Cas9, a gene editor for her FSN 660 lay
audience topic and during the AOCS meeting, there were three topics related to
the application of CRISPR-Cas9 to improve the yield of oilseeds or change the
lipid profile during culture. I am so proud of our food science program that it
is on the cutting edge of the latest science, technology and modern trends, and
I was able to relate what was introduced in class with specific topics in a
scientific meeting!
My advisor Dr. Lilian Were always encouraged
us to attend scientific meetings where we could have a chance to get close to
the most recent scientific topics and methods, to meet and get to know more
brilliant scientists and professionals. This time, I presented my research on “Greening,
reducing capacity, and protein oxidation in sunflower butter cookies as a
function of different acidic ingredients”, as a novel topic. People were mostly
curious about the sensory evaluation and consumers’ acceptance of sunflower
butter cookies greening, which could be a major focus for future studies.
In addition to learning tons about
new technologies and gaining more knowledge, the best part of attending awesome
scientific meetings, such as AOCS and IFT, is also making new friends with
other intelligent scientists and technologists. I feel that we are trying our
best to make our world better! AOCS is not as big as IFT, but it can let you
get close to all the topics you are interested in and ask or discuss questions
with the presenters. In addition, as AOCS mainly focuses on oil, lipid and
protein, the topics were more specific compared to IFT, and AOCS can give you
time to think about what you’ve learned during the meeting.
After a poster presentation in IFT
and two oral presentations in AOCS, if you are also doing research and will
attend scientific meetings, I would suggest oral presentation because during
your presentation time, the audiences focuses on your presentation and asks
questions after, which is more efficient and specific. Slides (with animation) and
your speech provide more information and communication. I think doing the poster
presentation is harder because of you need to have a very interesting catchy topic
(the TITLE) and well organized and standout poster, otherwise the audiences may
just glance over your poster and pass by without saying a word!
I feel so grateful that Dr. Lilian
Were was my thesis advisor. She has always been supportive and encouraged me to
do things that allow me to become a better student and worker. I could not have
accomplished all my achievement without her guidance, motivation, and selfless
help. I really appreciate everything she did for me. Many thanks to all my
brilliant lab mates: Amanda, Joele, Lan, and Natalie for always being by my
side and supporting me! I’d like to thank
Chapman University, Schmid College of Science & Technology for their
financial aid to support me to go to Minneapolis and get the chance to learn a
lot and make myself better.
