1:00 Basics of Mass Spectrometry for Lipids.
Mikhail Golovko, University of North Dakota

Mass spectrometry is a commonly used analytical technique for the study of lipids. In this presentation, we will describe the basics principles of mass spectrometry that include fundamental answers to questions such as “What is measured with mass spectrometers? How do we present MS data?” The major types of ionization and ion separation will be discussed. The principles of operation and scan modes of tandem mass spectrometers, one of the most common forms of mass spectrometers, will be covered.
1:50 Mass Spectrometry Approaches for the Study of Lipids.
Giuseppe Astarita, Denali Therapeutics

Innovative technologies are rapidly revolutionizing the way we conduct lipid research and learn about the chemical complexity of biological samples. Whether researchers want to conduct a comprehensive screening of all lipids (untargeted analysis) or analyze a more selected set of lipids (targeted analysis) or visualize the spatial localization of lipids in a biological samples (in situ and imaging analyses), a lipidomic research strategy presupposes the choice of the analytical solutions that are more appropriate for answering the biological questions posed. This presentation will describe how technological innovations in chromatography, ion mobility, mass spectrometry and informatics are contributing to the field of lipidomics.
2:40 Networking Break.
3:00 Mass Spectrometry Imaging of Lipids.
Jonathan V. Sweedler, University of Illinois at Urbana-Champaign

Mass spectrometry provides unmatched chemical detail on the precise forms of the lipids in a chemically and spatially heterogeneous sample such as the brain. Oftentimes, information on molecular localization is as important as knowledge of the molecules present in the tissue. The approach and capabilities of mass spectrometry imaging (MSI) are highlighted, including instrumentation and informatics useful for imaging lipids, fatty acids and related molecules directly from tissues. Both matrix-assisted laser desorption/ionization (MALDI) and secondary ion mass spectrometry (SIMS) imaging are covered. A unique capability of both MALDI and SIMS is the ability to probe the lipids directly from individual dispersed cells.
4:00 Roundtable Paper Discussion.

Lipids School faculty presenters include MS lipid experts Mikhail Golovko, University of North Dakota, USA; Giuseppe Astarita, Denali Therapeutics, USA; and Jonathan Sweedler, University of Illinois at Urbana–Champaign, USA.

There is no registration fee but registration will be limited to the first 60 registrants.

Hot Topics Symposia



Clean Label Ingredients and Processes for Food and Beverages

Monday, May 1
7:55-10:00 am

Organizers: G. Napolitano, Nestlé NDC, USA; and P. Rousset, Nestlé NDC, USA

The session will include the sources, usages, and functionalities of clean label and naturally perceived ingredients and additives replacing their widely used artificial and synthetic counterparts. Those food components include lipid antioxidants, emulsifiers, emulsion stabilizers, as well as major ingredients as conventional vegetable fats and oils.

The use of clean label and familiar ingredients in foods and beverages is not only an active trend in the industry, but it is also a requisite for good nutrition and health. Increasing regulatory pressure and consumer awareness make clean label alternatives an important factor for compliance and competitive advantage.

Approaches to clean label are not mere ingredient substitutions, but require new knowledge from many areas of research including ingredient sourcing, functionality, interactions, consumer research, and regulatory aspects.

MUFA: A Secret Weapon for Making “Healthy” Food Claims

Monday, May 1
7:55-10:00 am

Organizer: P.M. Kearney, PMK Associates, Inc., USA

The health and wellness marketplace is growing at a rapid pace and product developers, marketers, and consumers increasingly want to know what foods are truly “healthy”. FDA is in the process of updating the criteria for various health claims, including the use of the word “health”, particularly with regards to fats and oils. Unsaturated fats have moved to the forefront as substitutes for saturated and trans fats and monounsaturated fats (MUFA’s) are increasingly providing a broad spectrum of functional and health benefits. This session will discuss the issues raised by FDA on the use of the word "health" in labeling, examine new guidelines from the American Heart Association on healthy dietary patterns, delve into the functional benefits of unsaturated fats in the diet, discuss new research on how certain fatty acids can be used to manage weight and prevent chronic disease, and examine how ingredient innovation is leading to the development of healthier products.

7:55 Opening Remarks.
8:00 Overview on the Use of the Term “Healthy” in Labeling Food Products.
P.M. Kearney, PMK Associates, Inc., USA.
8:20 The Functional Benefits of Unsaturated Fats.

9:35 Panel Discussion, Q & A.



The Regulatory Changes—Impact on Lipids

Monday, May 1
7:55-10:05 am

Organizers: S. Bhandari, Merieux NutriSciences, USA; and P. Delmonte, FDA, USA

Recent regulatory changes have a big impact on the manufacturing of fats and oils. Most notably, on June 17, 2015, the FDA made a final determination that there is no longer a consensus among qualified experts that partially hydrogenated oils (PHOs), which are the primary dietary source of industrially-produced trans fatty acids (IP-TFA), are generally recognized as safe (GRAS) for any use in human food. The determination was based on the available scientific evidence and the findings of expert scientific panels establishing the health risks associated with the consumption of trans fat. Meanwhile, the discussion on what levels of trans fat should be adopted for “trans fat free” labelling is on-going in the United States, Canada, the European Union, and more globally by Committees within Codex Alimentarius. Separately, but still of great interest for the fats and oils industry, on June 22, 2016, President Obama signed the Frank R. Lautenberg Chemical Safety for the 21st Century Act, which updates the Toxic Substances Control Act (TSCA). The updated TSCA regulations include requirements for EPA to evaluate existing chemicals with clear and enforceable deadlines, new risk-based safety standards, and increased public transparency for chemical information.

It is important to understand these regulatory changes. The implications of these changes are of great interest to different segments of the AOCS community whether food processors, food manufacturers, lipid and fat processors/manufacturers, food quality control experts, regulators, analytical scientists and others. These changes have a direct effect throughout the food industry as they work to develop products in compliance with the new regulations.
