Chairperson’s Message

Dear Processing Division (PRO) Members:

I hope that most of you will have the opportunity to attend the 2015 AOCS meeting. This year the meeting will be in Orlando.  Registrants will see a new innovative conference program, giving attendees with similar interests more opportunities to network, collaborate, and learn. Three campuses represent AOCS interest areas. Each campus features concurrent technical sessions, an Industry Showcase, poster presentations, and networking breaks.

Grant Mitchell has been hard at work putting together the sessions.  Listed below are scheduled sessions.  More information is available at

Chairs: M.S. Alam, Texas A&M University, USA; and R. Clough, Texas A&M University, USA

Sunday Through Wednesday
Processing Poster Session
Chair: N.T. Dunford, Oklahoma State University, USA

Grant and the co-chairs have spent many hours recruiting speakers and reviewing potential abstracts for inclusion in their sessions. The executive board would like to extend our sincere thanks to them for supporting the Processing Division.


There is a hospitality suite taking place Monday and Tuesday nights (May 4/5) from 7:00-9:00.  Please drop by for a beverage and strike up a conversation with fellow processors.  We are fortunate to have a number of generous hospitality suite sponsors including: Alfa Laval, AWT, BASF Corporation, Buhler, Clariant Corp., Crown Iron Works, Desmet Ballestra North America, GEA Mechanical Equipment, HF Press+LipidTech, Oil-Dri Corporation of America, optek-Danulat Inc., Process Plus, and Solex Thermal Science.

The Processing Division Luncheon will be on Tuesday, May 5 from 12:45-2:15.  Tickets are available from AOCS.  The speaker this year will be Marc Kellens, Desmet Ballestra.  The title of Marc’s presentation will be "Oils and Fats Processing: Past, Present and Future."

It is hard to believe but planning for the 2016 Annual Meeting in Salt Lake City is already underway.  A survey has been emailed to Processing Division members about their interests.  A round table planning session is scheduled for Wednesday, May 6 in Orlando from 7:00-7:55 am.  Please drop by, have a coffee, and participate in the planning for 2016.  If you have an idea for a session; would like to contribute a paper; or perhaps be interested in co-chairing a session, please contact Grant Mitchell at Presenting at AOCS is a great way to expand your horizons and meet colleagues with similar interests in the industry.

Thank you for your membership in the Processing Division of AOCS. Your support is appreciated and your ideas and suggestions always welcome.  I hope to see you in Orlando!

Food texture and nutrition: the changing roles of hydrocolloids and food fibers
Hydrocolloids that have traditionally been used to provide texture only, are now being used for nutritional functionality. Intelligent processing of food fibers that allows for their use as food ingredients with nutrition and texture function; and the emergence of new clean label functional food fibers with texture and nutritional functionality are described in this article.


Isopropyl alcohol extraction of mustard oil
Hexane is a common extraction solvent in the industrial applications, but concerns over its contribution to air pollution have prompted the search for other extraction solvents. Isopropyl alcohol (IPA) has high solubility for triglycerides and it is safer than hexane due to its higher flash point, upper explosive limits, and auto-ignition temperature. The paper describes how IPA was used to develop a rapid method for extracting oil from dehulled yellow mustard.

Using high-intensity ultrasound to change the physical properties of lipids
The crystalline networks of fats that have been crystallized by sound waves are harder, more elastic, and more viscous than those produced through other processing methods. This article considers the potential benefits of using this novel technology as an additional tool to tailor the physical properties of low saturated fats and free trans-fats lipids in a way that produces healthier and functional trans-fat replacers. 


Dairy-based nano-encapsulation systems for the delivery of bioactive materials
Micronutrients encapsulated with milk-derived materials have greater stability during food processing and greater bioavailability in the body. The article describes how new encapsulation technologies will underpin the next generation of “clean label” functional foods.


Pilot Plants: smoothing the scale-up from lab to commercial production
Taking a process that has been developed and validated in the lab to full-scale production can be risky and time consuming. An expert in surfactants manufacturing explains how pilot plants expedite the scale-up to full-scale production by preventing costly and time-consuming mistakes.  


Optimizing desolventizer-toaster dome temperature
Industrial plants that are already up and running cannot make drastic changes to basic processes without facing serious down time. The article describes how Advanced Process Control (APC) was used to optimize the dome temperature of a desolventizer-toaster at a large soy-bean processing plant without downtime.

Commercial-scale biodiesel using immobilized enzymes and waste feedstock
Alkaline catalysts are most widely used in the industry for biodiesel production. This process requires the use of high-pure grade feedstocks. Because of the high cost of enzymes and its propensity to be deactivated by methanol, they cannot compete with chemical catalysts for biodiesel production. This article describes a commercial immobilized enzyme technology that can convert all types of feedstocks, including brown grease, into biodiesel.

Lowering the boiling curve of biodiesel by metathesis
Biodiesel is presently the blend component predominantly used in the diesel fuel. Unfortunately its high boiling curve is not well-suited for modern passenger car engines with diesel particle filters. Scientist describe in this article how they have used metathesis to lower the boiling curve of biodiesel and conducted emissions tests of the resulting fuels in three different diesel engines.


Approaches to mitigating esters of both 3-MCPD and glycidol
Esters of 2- and 3- monochloro-1,2 propanediol (MCPD) and glycidol in edible oils are a health concern, because these compounds in their free state are classified as  probably carcinogenic  to humans. Fortunately, there are many opportunities throughout the production chain to reduce their formation. This article describes several strategies for mitigation in raw materials, during refining and in fully refined oils.

Development of the first efficient membrane separations of cis fatty acids 
Fatty acids are an important feedstock for the chemical industry and expected to increase in global worth at a rate of about 13.6% per year (from 2012) to $13 billion by 2017. This article describes how a group of scientists has developed membranes that can rapidly separate and purify both cis fatty acids and cis fatty acid esters to >95% purity.


Reactive seed crushing of castor seeds to produce methyl ester
Oil from castor seed has the potential as a feedstock for biodiesel and jet fuel production. Unfortunately, castor oil production suffers from high processing costs and generates toxic waste in the meal. In this article a scientist from one of the largest consumers of castor seed oil describes a sustainable process the company has developed for castor oil production.
