Midweek Mixer: The art of presenting posters and communicating science

 Congratulations! Your poster or talk has been accepted to present! Now what?

Join us for a Midweek Mixer to discuss strategies and learn how to present your research in a clear and compelling manner. The main focus will be on e-poster presentations at the AOCS Annual Meeting & Expo (which include a short recorded presentation/pitch), but the ideas and techniques will be valuable for oral presentations, and for any situation in which you share your research. 

We will discuss the importance of communicating our work, how to grab audience attention (and keep it!) and how to transform technical data into a language that everyone understands. This will be an interactive session with games and anecdotes as we delve into science communication in this new online reality. Can we convey our enthusiasm during online presentations? Does practice make perfect? How do we make a poster presentation and pitch appealing to people in other fields? We will touch on these questions and more.

Join host, Marnie Newell and moderator, Sarah Willett, Co-chair of the AOCS Young Professional Common Interest Group, April 15, 2021, 12 p.m. noon, CDT (Chicago, USA; UTC -5).

Registration is free for all, including those that are not AOCS members. 

AOCS Midweek Mixers provide an excellent opportunity for networking and learning with your peers.

About the host: Marnie Newell

New method for assessing trypsin inhibitor activity in plant-based food materials including soybeans, pulses, beans, cereals and their processed products.

 AOCS is the leading provider of methods and recommended practices critical to running a quality lab in the fats, oils and plant-protein industries, and recently approved a new method, Method Ba 12a-2020, for assaying trypsin inhibitor activity in plant-based food materials including soybeans, pulses, beans, cereals and their processed products.

trypsin inhibitor from Erythrina caffra seeds.
Trypsin inhibitors are found in a wide range of plants including pulses, beans and cereals. These proteins are thought to have evolved as part of the plants’ strategies to deter consumption by animals and irreversibly bind to enzymes involved in protein digestion. High levels of trypsin inhibitor activity in animal feed leads to decreased weight and has been linked to metabolic and digestive diseases. Humans have developed a range of approaches to disarm this defense, including denaturing by heating (processing or cooking), and selective breeding of plants. The ability to reduce, and, most critically, to accurately quantify, the trypsin inhibitor activity in plant material has been key to the development and production of new plant-protein based foods for animal and human consumption.

AOCS has had an official Method for measuring trypsin inhibitor activity since 1975. As part of the ongoing process of method revision, a new Method Ba 12a-2020 has recently been approved by the AOCS Uniform Methods Committee. Keshun Liu, a Research Chemist with United States Department of Agriculture, Agricultural Research Service (USDA-ARS), has led this effort. 

“The new method is easier to learn, requires smaller amounts of reagents and gives results with greater precision,” he says.

Method Ba 12a-2020 assesses inhibitor activity from the increase in light absorbance at 410 nm using Nα‐benzoyl‐DL‐arginine‐ρ‐nitroanilide as a synthetic trypsin substrate. It has an expanded scope, addressing the need for analytical methods for non-soy plant proteins. It also provides results using more meaningful units of measurement.

“Using AOCS Ba 12a-2020 analysts can now express results as the amount of trypsin inhibited, instead of using an arbitrary unit,” says Liu. “The new unit is standardized against a reference trypsin with a fixed value of specific enzyme activity.  If other methods adapt this new concept of standardization against the same reference trypsin, results will become comparable among reports.”

“The creation and validation of methods that encourage comparison of measurements from different laboratories is central to AOCS’s mission,” says Scott Bloomer, ‎Technical Services Director at AOCS. “The genesis of our society in 1909 was a collaborative effort among cottonseed producers to standardize analytical results.”

An international collaborative study of the new AOCS Ba 12a-2020 Method was recently conducted. Results are reported in a recent JAOCS article. You can purchase the Method at the AOCS Store.

A new AOCS Laboratory Proficiency Program (LPP) series will be launched in conjunction to AOCS Ba 12a-2020. For more information please contact Dawn Shepard dawns@aocs.org.

Celebrating the California Olive Oil Council - Laboratory Proficiency Program Winners!

AOCS is proud to recognize the top performers in the AOCS Laboratory Proficiency Program (LPP). The California Olive Oil Council’s Taste Panel achieved the top score in last year’s Proficiency Program for olive oil sensory laboratories. 



During the 1990s (the early days of California’s olive oil renaissance and the Council), the California Olive Oil Council (COOC) hosted several taster trainings and informal meetings prior to establishing its Taste Panel in 1998, which was then led by 2 IOC-trained Panel Supervisors dedicated to growing a high-quality industry in California. Today there are 19 members of the panel, all of whom have demonstrated their sensory expertise during multi-year apprentice programs. The Taste Panel spends 6 months each year certifying oils for the COOC Extra Virgin Seal Certification program, with the remainder of the year devoted to educational activities focused on increasing all tasters’ skill levels. 



"The COOC Taste Panel has participated in the Proficiency Program since its inception, and appreciates the recognition it has received from the AOCS," says Patricia King, Executive Director, California Olive Oil Council.




AOCS would like to congratulate the COOC taste panel on their excellent performance in the LPP,  and to commend them for their dedication to conducting rigorous analyses in the lab.
