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: 6797307Abstract: The invention relates to a method for preparing an oat product enriched in the content of &bgr;-glucan as well as a method for preparing a foodstuff incorporating such an enriched oat preparate. The invention uses dehulled or naked oats, which are subjected to dry milling and dry fractionation at multiple stages without a preceding removal of fat. The oat material is at a first stage subjected to dry milling and dry classification to separate a coarser fraction containing grain cell wall material and starch containing subaleurone layer as a pre-enriched fraction from a finer, endosperm containing fraction. At a second stage said pre-enriched fraction is subjected to dry milling, where the disintegraing action is more effective than at the first stage, and to dry classification for separating a coarser, cell wall material containing fraction as the enriched product from a finer, starch containing fraction.Type: GrantFiled: April 8, 2002Date of Patent: September 28, 2004Assignee: Avena OyInventors: Yrjö Mälkki, Olavi Myllymäki, Kaija Teinilä, Seppo Koponen

Patent number: 6440479Abstract: Flaxseed husk is removed from flaxseed core by abrasion.

Patent number: 5929231Abstract: The subject of the invention is a method for preparing fine-granuled starch from kernels of oats or rice. In the method, the kernels are ground and the starch is separated from the starch containing fraction obtained by the milling. An essential feature of the invention is that a suspension of the said fraction or of starch separated from it is treated with a surface-active agent or a lipolytic enzyme for disintegrating compound granules or aggregates of starch granules. Except the particle size, also functional properties of starch are affected. Disintegration of compound granules is enhanced by alkaline conditions and by mixing of the suspension. The fine-granuled starch obtained can be applied in foods and, for instance, for biodegradable plastics and for surface treatment agents. The invention can be included as a part of an integrated fractionation process, in which, in addition to starch, an oil fraction, an enriched fibre fraction, and a surplus fraction suitable for feed, are obtained.Type: GrantFiled: January 17, 1997Date of Patent: July 27, 1999Assignee: Exavena OyInventors: Yrjo Malkki, Olavi Myllymaki, Risto Tuomela

Patent number: 5846590Abstract: The subject of this invention is a method for producing a product with an enriched content of soluble dietary fiber, such as .beta.-glucan and/or pentosans from a raw material deriving from cereal grains, by using thermal, enzymatic or osmotic treatments or combinations of these. As a first step, suspending of milled cereal or a fraction of cereal in water and when needed, a limited proteolysis is performed in order to improve the solubility of the fiber. Temperature of the mixture is elevated, and the soluble fiber is precipitated with a polar organic solvent on solid carrier particles, which can derive from the raw material or are added in the suspension. A fine fraction, consisting primarily of starch, is separated from the more coarse fraction containing the precipitated fiber, by using methods based on the particle size or density.Type: GrantFiled: December 4, 1995Date of Patent: December 8, 1998Assignee: Exavena OYInventors: Yrjo Malkki, Olavi Myllymaki

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
