Problems solved by technology

Unfortunately, the viscosity was not significantly reduced, but the supply of arabinoxylan was delayed and required the use of expensive and complex methods and devices (multi-stage filtration and / or ethanol evaporation)

Embodiment 1

[0199] This example image 3 shown.

[0200] The following equipment was used in Example 1:

[0201]

[0202]

[0203] Step 1:- From eg figure 1 The pentosan fraction (18) was obtained in the indicated high pressure decomposition (HPD) process (supra).

[0204] Step 2:- Mix 300 g of pentosan component (18) with 1000 g of water to make a pentosan slurry comprising about 23 wt% pentosan component and about 77 wt% water.

[0205] Step 3:- Add endoxylanase in the amount of 100 ppm to the slurry and adjust the pH to about 5.5. The slurry was stirred for about 2 hours at a temperature of about 40°C to convert the insoluble arabinoxylan to soluble arabinoxylan. After this period, it was noted that the viscosity had decreased from above 3000cP to below 500cP ( Figure 4 ).

[0206] Step 4:- Cool the slurry and then centrifuge at room temperature (20°C-25°C) at a centrifugal force of about 6000G for about 60 minutes.

[0207] Step 5:- From 550 g of solid phase (192 g dry w...

Abstract

A method for the production of an arabinoxylan-enriched preparation from a pentosan fraction derived from a wheat flour comprising the following sequential steps: mixing the pentosan fraction with water to obtain a pentosan slurry; centrifuging the slurry to obtain liquid and solid phases; and drying the liquid phase to provide the arabinoxylan-enriched preparation. Also provided are methods for the production of: a starch- and protein-enriched intermediate from wheat flour; a glucose-enriched preparation from wheat flour; and a starch- and protein-enriched material from wheat flour. Furthermore, there is provided a use of an arabinoxylan-enriched preparation in one or more of: food, immune stimulants, prebiotics, nutraceuticals, pharmaceuticals and food supplements. There is also an apparatus for the production of an arabinoxylan-enriched preparation from a pentosan fraction of wheat flour.

Description

technical field [0001] The present invention generally relates to the production of arabinoxylan (arabinoxylan)-rich formulations. More particularly, but not exclusively, the present invention relates to the use in the production of pentosan fractions derived from wheat flour separation processes such as high pressure disintegration (HPD) treatment of wheat flour. Methods and apparatus for formulations containing arabinoxylan and other by-products. Background technique [0002] High pressure disintegration (HPD) is a known method of separating starch and gluten (gluten) from wheat flour by exploiting their differences in solubility, density and size. HPD is one of four recognized industrial methods (Martin; Alfa-Laval / Raisio; Hydrocyclone; and High Pressure Decomposition (HD)) for the separation of wheat starch and gluten. These methods differ mainly in the form of the flour-water mixture supplied to the centrifuge, hydrocyclone or sifter, or in the primary separation prac...
