摘要
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.
