An oil rich in polar lipids obtained from the method is disclosed, said oil I contains at least 40, preferably at least 50 lipid % polar lipids as calculated on the total amount of lipids in said oil and that the total amount of polar solvent and water in said oil is between 20 and 30 wt %. An oat oil containing high amounts of estolides of DGDG can further be obtained.Type: GrantFiled: March 10, 2010Date of Patent: October 21, 2014Assignee: Swedish Oat Fiber ABInventor: Magnus Härröd

Patent number: 8852606Abstract: Precipitated bacterial capsular polysaccharides can be efficiently re-solubilized using alcohols as solvents. The invention provides a process for purifying a bacterial capsular polysaccharide, comprising the steps of (a) precipitation of said polysaccharide, followed by (b) solubilization of the precipitated polysaccharide using ethanol. CTAB can be used for step (a). The material obtained, preferably following hydrolysis and sizing, can be conjugated to a carrier protein and formulated as a vaccine. Also, in vaccines comprising saccharides from both serogroups A and C, the invention provides that the ratio (w/w) of MenA saccharide:MenC saccharide is >1.Type: GrantFiled: January 14, 2009Date of Patent: October 7, 2014Assignee: Novartis AGInventor: Paolo Costantino

Patent number: 8841441Abstract: The invention relates to a method for producing regenerated biopolymers in the form of carbohydrates, using a solvent system that contains the biopolymers dissolved therein. The solvent system is based on a melted ionic liquid and optionally a protic solvent or a mixture thereof. The biopolymers dissolved in the solvent system are precipitated in a coagulation medium, said medium comprising a protic coagulant or a mixture of protic coagulants. The method according to the invention is characterized in that the surface tension ? of the coagulant or the mixture of coagulants is 99% to 30% of the surface tension ? of water, the surface tension being measured according to ASTM D 1590-60 at a temperature of 50° C. The method according to the invention is economical and flexible and leads to advantageous products, especially in the form of staple fibers which are especially not fibrillated and have an advantageous wet to dry strength ratio.Type: GrantFiled: November 13, 2008Date of Patent: September 23, 2014Assignee: BASF SEInventors: Eric Uerdingen, Michael Siemer, Michael Lutz, Thomas Wisniewski, Frank Hermanutz, Frank Gaehr

Publication number: 20140275519Abstract: A method for obtaining solutions of non-structurally modified salts of alginate, with endotoxin content less than 20 EU/g includes obtaining an alginate solution having a concentration ranging from 1.6 to 2.0% by weight by adding commercial grade alginate powder to a saline solution. The alginate solution obtained is filtered on at least one hydrophilic filter, and a filtered alginate solution is recovered. The filtered alginate solution obtained is further filtered on a charge-modified hydrophobic filter, and an alginate solution having an endotoxin content less than 20 EU/g is recovered.Type: ApplicationFiled: May 30, 2014Publication date: September 18, 2014Applicant: GH Care, Inc. d/b/a Altucell, Inc.Inventors: Giuseppe Pietro Pio Basta, Riccardo Calafiore
