Patent number: 9845365Abstract: The present invention provides a method for the extraction and isolation of soluble arabinoxylan products from cereal grain. Preferably, such soluble arabinoxylan product is any one of soluble arabinoxylan, arabinoxylan-oligosaccharides, xylose, arabinose, ferulic acid and mixtures thereof. Said method comprises partial debranning of whole cereal grains to obtain partially debranned cereal grains followed by roller milling of said partially debranned cereal grains to obtain cereal bran. The method further comprises the mashing of at least part of said cereal bran in water optionally involving the treatment of the mash with any one of an enzyme preparation, an acid, a base, a peroxide or combinations thereof, either simultaneously or sequentially, to solubilize and optionally depolymerize a fraction of the arabinoxylan comprised in said cereal bran. Preferably, said treatment is done with an enzyme preparation containing an endoxylanase.Type: GrantFiled: September 19, 2013Date of Patent: December 19, 2017Assignee: CARGILL, INCORPORATEDInventors: Willem Broekaert, Jan Delcour, Wim Veraverbeke

Patent number: 9428761Abstract: The present invention relates generally to the field of molecular biology and concerns a method for enhancing various economically important yield-related traits in plants. More specifically, the present invention concerns a method for enhancing yield-related traits in plants by modulating expression in a plant of a nucleic acid encoding a Yield Enhancing Protein (YEP). The YEP is selected from a Vacuolar Processing Enzyme (VPE) or a CCA1-like polypeptide or a SAP-like polypeptide or a Seed Yield Promoting Factor 1 (SYPF1) polypeptide or a Ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) activase (RCA) polypeptide. The present invention also concerns plants having modulated expression of a nucleic acid encoding such a YEP, which plants have enhanced yield-related traits relative to control plants. The invention also provides hitherto unknown YEP-encoding nucleic acids, and constructs comprising the same, useful in performing the methods of the invention.Type: GrantFiled: August 20, 2013Date of Patent: August 30, 2016Assignee: BASF Plant Science GmbHInventors: Willem Broekaert, Christophe Reuzeau, Ana Isabel Sanz Molinero, Valerie Frankard

Publication number: 20150191737Abstract: The present invention provides several promoters isolated from Oryza sativa, which promoters are capable of driving and/or regulating the expression of an operably linked nucleic acid in a plant. The expression patterns of the promoters according to the present invention have been studied in Oryza sativa and some of the promoters displayed specific activity in particular cells, tissues or organs of the plant, while others displayed constitutive expression throughout substantially the whole plant. Some promoters showed weak expression, while others were strongly active.Type: ApplicationFiled: May 12, 2014Publication date: July 9, 2015Applicant: CROP DESIGN N.V.Inventors: Yves Hatzfeld, Willem Broekaert

Patent number: 8927038Abstract: The present invention relates to preparations comprising (arabino)xylan oligosaccharides with average degree of polymerisation between 4 and 10 and average degree of arabinose substitution between 0.15 and 0.35, which beneficially modulate the intestinal flora, such preparation comprising both xylo- and arabinoxylo-oligosaccharides. Preferably, the arabinoxylooligosaccharides are substituted in part by hydroxycinnamic acids and exert antioxidant effects. Furthermore, it is preferred that the preparations according to the present invention have a nitrogen content below 0.16% (w/w) in order to ensure good organoleptic and color properties, particularly upon heating said preparations. In addition, food, beverage and nutritional supplement products comprising the preparations are provided as well as methods to prepare the said preparations.Type: GrantFiled: March 25, 2009Date of Patent: January 6, 2015Assignee: Cargill, IncorporatedInventors: Willem Broekaert, Christophe Courtin, Jan Delcour

Publication number: 20140097106Abstract: The present invention provides a container suitable for the packaging and storage in separate compartments of at least two products, which need to be combined to prepare a ready-to-use product, such as a ready-to-eat food product. When the preparation of the ready-to-use product is desired, the container of the present invention allows to easily combine the contents of said compartments and to evacuate the combined products from the container through a closable opening without dislodging any one of the compartments from one another. In case the container is used to package and store components of a ready-to-eat food product, it is preferred that the design of the container allows for the practical consumption of the prepared ready-to-eat food directly from the container.Type: ApplicationFiled: May 23, 2012Publication date: April 10, 2014Applicant: B-TEK BVBAInventors: Willem Broekaert, Isabelle Francois, Wim Veraverbeke, Geo Hagen, Olivier Lescroart
