Publication number: 20230407355Abstract: The present invention relates to a method for preparing oligosaccharides which can be used among others as food additives to reduce calorie content, to sweeten food products, to increase the fiber content of food products, to improve the texture of food products and to stimulate the gut microbiome bacteria. Furthermore they can be applied in the fields of animal feed, or other applications. More particularly, this invention is directed to a high temperature hydrolysis of xyloglucan polysaccharide to defined xyloglucan oligosaccharides. The invention further relates to oligosaccharide hydrolysates produced with the method of the invention and to the use of said oligosaccharide hydrolysates in human and/or animal nutrition, as prebiotic or other uses. Further provided are novel endoglucanases for use in the method of the invention as well as in other applications.Type: ApplicationFiled: March 13, 2023Publication date: December 21, 2023Applicant: TECHNISCHE UNIVERSITÄT MÜNCHENInventors: Sigrid GRAUBNER, Vladimir ZVERLOV, Wolfgang SCHWARZ, Petra EICHINGER, Björn ANDREESSEN, Jonathan HERLET, Matthias MECHELKE, Philipp SCHULTE, Wolfgang LIEBL

Publication number: 20210071161Abstract: The present invention relates to novel polypeptides with xylanase activity, especially xylanase variants, such as genetically engineered xylanase variants, which show improved thermostability, improved resistance against acid treatment and increased enzyme activity on arabinoxylan. The invention includes the use of said polypeptides in applications, such as for food or feed, for brewing or malting, for the treatment of xylan containing raw materials like grain-based materials, e.g. for the production of biofuels or other fermentation products, including biochemicals, and/or for the wheat gluten-starch separation industry, and methods using these polypeptides, as well as compositions (such as feed additive compositions) comprising said polypeptides.Type: ApplicationFiled: November 22, 2018Publication date: March 11, 2021Applicant: TECHNISCHE UNIVERSITÄT MÜNCHENInventors: Sigrid GRAUBNER, Vladimir ZVERLOV, Wolfgang SCHWARZ, Waldemar HAUF, Björn ANDREESSEN, Louis Philipp SCHULTE, Wolfgang LIEBL
