Patent number: 9890403Abstract: The present disclosure relates to methods for producing microbial lipids. The present disclosure also relates to methods for producing microbial lipids using inhibitors obtainable from lignocellulosic materials to suppress the proliferation of unwanted microorganisms in the fermentation broth. The method can therefore reduce the risk of having contaminating microbes establish in the system and the cultivation and thus higher yields of microbial lipids may be obtained.Type: GrantFiled: December 11, 2014Date of Patent: February 13, 2018Assignee: NESTE OYJInventors: Heidi Vainio, Mika Sipponen, Simo Laakso, Ossi Pastinen, Ilkka Lehtomäki, Perttu Koskinen, Miia Laamanen

Patent number: 9115317Abstract: The invention relates to a method for the recovery of oil from an aqueous solution containing oil and solids, as well as to the use of products obtained by this method. The method of the invention comprises at least the following steps of: Adjusting the oil- and solids-containing aqueous solution to a pH which is acidic, separating an oil- and solids-containing fraction from the acidic aqueous solution with an separation agent which is hydrophilic or assumes a hydrophilic character in response to water, recovering the oil- and solids-containing fraction separated by means of said separation agent, extracting oil away from the solids with a water-insoluble extraction agent, and recovering the oil-containing water-insoluble extraction agent.Type: GrantFiled: February 17, 2012Date of Patent: August 25, 2015Assignee: Neste Oil OyjInventors: Miia Mujunen, Ossi Pastinen, Ilkka Lehtomaki, Simo Laakso, Perttu Koskinen

Patent number: 8742095Abstract: The present invention relates to a method of manufacturing a cereal bran product containing beta-glucan. According to the method, a plastic mass is formed from cereal bran by means of a thermo-mechanical treatment, and the mass is brought into contact with an enzyme that breaks up beta-glucan, with or without an enzyme that breaks up starch. After inactivating the enzyme, the bran is dried and, when so needed, ground. The cereal bran product manufactured according to the method has an essentially inextensible structure in a water environment. The product is suitable to be added to aqueous foodstuffs or to foodstuffs, the manufacture of which employs water.Type: GrantFiled: March 4, 2009Date of Patent: June 3, 2014Assignee: Valtion Teknillinen TutkimuskeskusInventors: Ilkka Lehtomäki, Olavi Myllymäki

Publication number: 20070128322Abstract: The invention relates to a method for improving the solubility of non-starch polysaccharides of a vegetable material. The products prepared by the method and the use of the products are also included in the scope of the invention. The method comprises crushing of the material by mechanical energy to form particles, with at least a major portion of the cells containing non-starch polysaccharides in the material being damaged. Preferably, the non-starch polysaccharides end up in particles as produced by crushing to form particles smaller than that of the initial cell containing these polysaccharides in the material. Disruption of the cells allows effective interaction between the dissolving medium and the polysaccharides to be dissolved, appearing as increased solubility. The material crushing can be performed under the joint effect of pressure, heat and shearing forces.Type: ApplicationFiled: May 6, 2004Publication date: June 7, 2007Applicant: Suomen Viljava OyInventors: Jenni Haapiainen, Olavi Myllymaki, Pekka Lehtinen, Ilkka Lehtomaki, Simo Laakso, Markku Patajoki

Patent number: 5183677Abstract: The present invention relates to a beta-glucane enriched grain fiber, and to a process for the preparation of a cellulose-containing, beta-glucane enriched grain fiber, preferably of oats or barley, for use as food or as a raw material or additive in the food industry. In the process, a ground or unground grain such as oats or barley is slurried rapidly in cold water, which may contain an organic solvent. The slurry is homogenized rapidly and is then screened, whereby a beta-glucane containing fiber is obtained.Type: GrantFiled: September 25, 1991Date of Patent: February 2, 1993Assignee: Oy Alko ABInventors: Ilkka Lehtomaki, Pertti Karinen, Risto Bergelin, Olavi Myllymaki
