The present invention concerns a method for selectively activating a thermostable hydrolase at a temperature above T1. The present invention provides compositions comprising a thermostable hydrolase and a temperature sensitive inhibitor, wherein said thermostable hydrolase and said temperature sensitive inhibitor form a hydrolase-inhibitor complex at a temperature below T1, but which dissociates at a temperature of about T1. The present invention also relates to uses of said compositions, and a method for preparing said compositions.

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. The method further comprises the separation from said mash of a solubilized fraction, which comprises at least part of the solubilized soluble arabinoxylan products.

A method for increasing in a baked product, after baking, the level of water-soluble arabinoxylan with an average degree of polymerization ranging from 5 to 50, comprising preparing a dough for a baked product with flour having a total arabinoxylan content of at least 2.0%, and adding to the dough an enzyme preparation comprising at least one thermophilic endoxylanase in an amount at least two-fold higher than the amount conferring 90% of the maximal bread volume increase obtained by addition of such enzyme preparation to the recipe of the baked product. Using this method, baked products can be obtained that have a level of arabinoxylan of at least 1.7% The present invention further relates to baked products obtainable by this method, and to an improver and a dough which may be used for the preparation of such products.

Bread with increased arabinoxylo-oligosaccharide content

The present invention relates to the use of oligosaccharides derived from arabinoxylan for use in the prevention and treatment of gastrointestinal infection. More particularly the invention provides a method for preventing or reducing the gastrointestinal infection of a animal or human being with bacteria associated with gastroenteritis through the supplementation of their diets with the said oligosaccharides.

Arabinoxylo-oligosaccharides useful against gastrointestinal infections

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.

(Arabino)xylan oligosaccharide preparation

The present invention provides nutritional compositions, more particularly food supplements and processed food products, enriched with arabinoxylan-oligosaccharides and further comprising either or both water-unextractable arabinoxylans or water-soluble arabinoxylans. Preferably said nutritional compositions comprises both arabinoxylan-oligosaccharides and water-unextractable arabinoxylans.

Nutriment containing arabinoxylan and oligosaccharides

The present invention relates to compositions of low molecular mass arabinoxylans for use as dietary supplements and to methods of improving growth performance and feed utilization of animals through the supplementation of their diets with the said compositions. In a preferred embodiment, the low molecular mass arabinoxylans are derived from natural sources, such as plant material and more preferably of cereals. They can be selected fractions of said natural arabinoxylans or can be obtained by acid and/or enzymatic depolymerization or fragmentation of said natural arabinoxylans or they can be structural analogues produced by chemical and/or physical processes.

Non-starch-polysaccharides

The present invention provides a method for producing preparations comprising soluble arabinoxylans as co-products of ethanol production through fermentation of whole-grain cereals. The method results in preparations that are highly enriched in soluble arabinoxylans, which can be used as a food, beverage, or feed ingredients.

Method for making soluble arabinoxylans as co-product of fermentation of whole-grain cereals

This invention consists of a modified gluten biopolymer for use in industrial applications, such as composites and foams. In the present work, the fracture toughness of the gluten polymer was improved with the addition of a thiol-containing modifying agent. This work also resulted in the development of a gluten biopolymer-modified fiber bundle, demonstrating the potential to process fully biodegradable composite materials. Qualitative analysis suggests that a reasonably strong interface between the natural fibers and biopolymer matrix can form spontaneously under the proper conditions. Therefore this invention relates to a modified gluten biopolymer for use in industrial applications, such as composites, stabilized foams and molded articles of manufactures. The present invention relates to a new gluten based biopolymer with modified properties, such as an increase in impact strength, and prepared by using thiol-containing molecules. The multifunctional activity of the polythiol-containing molecules generates the potential for the development of a new material base for commodity plastics. The invention furthermore relates to a new composite material comprising gluten-coated fiber, its use and the method for preparing the composite material.
