Abstract

The present invention relates to a composition comprising citrus fruit fiber having a water binding capacity of from 8 to 25 (w/w) and native starch selected from the group consisting of corn starch, rice flour, sorghum starch, tapioca starch and mixture thereof.

First claim

The invention claimed is:

1. A process for preparing a composition comprising the steps of:
a) making a mixture consisting of citrus fruit fibers and native starch at a weight ratio of citrus fruit fiber to native starch of 1:5 to 1:2, wherein the citrus fruit fiber is fiber extracted from citrus vesicles which has a water-binding capacity of 7 to 25 grams of water per gram of fiber and a total dietary fiber content of 60 to 85 wt %, the total dietary fiber consisting of 45 to 50% soluble dietary fiber and 50 to 55% insoluble dietary fiber and wherein the native starch is selected from the group consisting of corn starch, rice flour, sorghum starch, tapioca starch, waxy wheat flour, amylose-free potato starch and mixtures thereof,
b) mechanically treating the citrus fruit fiber and the native starch with a high shear force to obtain a homogeneous mixture, and
c) cooking the homogeneous mixture under gentle stirring up to the gelatinization temperature of the starch,
wherein the composition exhibits improved resistance to shear treatment relative to native starch alone.

2. The method according to claim 1 characterized in that the weight ratio of citrus fruit fiber to native starch is between 1:5 and 1:3.6.

3. The method according to claim 1 characterized in that the citrus fruit fiber is obtainable from citrus fruit selected from the group consisting of oranges, tangerines, limes, lemons, and grapefruit.

4. The method according to claim 1 characterized in that the citrus fruit fiber comprises from 8 to 12% (w/w) proteins.

5. The method according to claim 1 characterized in that the native starch is a waxy starch.

6. The method according to claim 5 characterized in that the native starch is glutinous rice flour.

7. The method according to claim 1 , wherein mechanical treatment is applied via equipment selected from a group consisting of high shear mixers, high pressure valve homogenization, microfluidization, and high power ultrasound.
