Rotterdam was European Capital of Culture in 2001. The city has its own orchestra, the Rotterdam Philharmonic Orchestra with its world famous musical director Yannick Nézet-Séguin, who will be performing in De Doelen, our congress venue.
A major zoo called Diergaarde Blijdorp is situated at the northwest side of Rotterdam, complete with a walkthrough aquarium called the Oceanium.
The self-image of the city is that of a no-nonsense workers' city. In that sense, there is a healthy competition with Amsterdam, which is often viewed as the cultural capital of the Netherlands. There is a saying: "Amsterdam to party, Den Haag (The Hague) to live, Rotterdam to work". Another one, more popular by Rotterdammers, is "Money is earned in Rotterdam, divided in The Hague and spent in Amsterdam".
Rotterdam has many museums. The well known museums are the Boijmans-van Beuningen Museum (a visit is a part of the social programme of the congress!), the NAi (Netherlands Architecture Institute), the Volkenkundig Museum (foreign peoples and cultures), the Kunsthal (design by Rem Koolhaas),the center for contemporary art Witte de With,the Maritiem Museum and the Brandweermuseum (Fire brigade museum). The Historisch Museum (Historical museum) has two buildings: the Dubbelde Palmboom and the Schielandshuis. Other museums include the tax museum and the nature historical museum. At the historical shipyard and museum Scheepswerf 'De Delft the reconstruction of Ship of the Line 'De Delft' can be visited.

It is not always the big news that make life interesting. Every day the Euro Fed Lipid headquarters receives or produces small bits and pieces of information worth noting but not important enough to get coverage in the monthly newsletter. For those of you with a facebook account we recommend to become a fan of Euro Fed Lipid. You also can leave messages on the wall that you would like to share.
For those not using this social network we have added an application on the Euro Fed Lipid webpage that mirrors the headlines.

The use of enzymes to modify edible oils has grown in the last twenty-five years from being an alternative to the chemical method of degumming oils such as soyabean oil to becoming a highly versatile process, used for a variety of structure-modifying processes.
The lipases have since become more widely used tools in the processing of various lipids, effective in processes such as interesterification as well as the production of diacylglycerols. The production of structured lipids as well as other triacylglycerols formed with the aid of enzymes provides yet more evidence of their versatility, and such examples will be discussed in this conference by scientists and technologists who have been directly involved in their development. Most recently the use of enzymes in the production of bio-fuels has been signalled.
The conference will provide a detailed review of the opportunities
now available, including a review of Life Cycle Analysis when using
The speakers are drawn from both industry and academia to provide
both relevant and practical information as well as the latest research
into the application of lipases in oil processing and modifi cation
Exhibition and sponsorship opportunities are available. Posters are also invited.

Special issue of EJLST
Esters of chloropropanol and glycidol
3-Monochloropropane-1,2-diol (3-MCPD) is a carcinogenic contaminant occurring in some heat-processed foods, along with other related chloropropanols which are suspected to be toxic as well. While the toxicology of 3-MCPD has been thoroughly studied, little is known about its fatty acid esters, often found in refined oils and fats. Chloropropanol esters are structurally similar to triacylglycerols and in vitro experiments have shown that they can be hydrolyzed by intestinal lipases, releasing free chloropropanols. In addition, esters of another strong carcinogen, glycidol, are formed in oils and fats during the refining, and can also serve as precursors for the formation of chloropropanols. The March issue of EJLST comprehensively covers the current knowledge about esters of chloropropanols and glycidol in fats and oils. The issue brings excellent review and research articles on their analysis, toxicology, and chemistry, as well as strategies for mitigation of the levels in processed food. This issue, edited by Dr. Bertrand Matthäus from the Max Rubner Federal Research Institute for Nutrition and Food in Detmold, Germany, is a must-read for all lipid and food scientists and technologists!
Developments in oil extraction from microalgae
Microalgae are a diverse group of organisms with great potential for industrial applications such as
feedstock in aquaculture or production of oils, carotenoids, and other specialty lipids (arachidonic acid, EPA, DHA) as well as enzymes; the bioproducts can be used both for food and non-food purposes. While the potential is clearly present, poor production yields are limiting the industrial significance of microalgae. However, recent developments in molecular biology have improved production yields of algae bioproducts. In addition, optimization of the processing can enhance the productivity significantly.
Mercer and Armenta from Dartmouth, Nova Scotia, Canada reviewed the last 10 years of progress in technologies for extracting and purifying microalgae oil. They compared solvent extraction technologies with alternative extraction procedures such as mechanical milling and pressing or enzymatic and supercritical ?uid extraction. The advances in molecular engineering of microbes that can aid oil extraction are also presented. Another important aspect of lipid production from microalgae is the environmental impact of the production which is thoroughly discussed, and the economic costs are carefully considered.
