Viscosity control in compositions comprising plant fiber materials
First Claim
1. A method of increasing viscosity-increasing effects of an edible refined cellulose fiber comprising:
- providing an aqueous volume;
adding to the aqueous volume from 0.5% to 20% by weight of edible refined cellulose fiber to form a first reagent composition;
adding from 0.025% to 8% by volume of pectinase or pectinmethylesterase to the first reagent composition at a temperature of from 20°
C. to 80°
C.;
allowing the enzyme to modify the refined cellulose fiber for at least 15 minutes to form a final liquid composition; and
removing the modified refined cellulose from the final liquid composition;
and removing liquid from the final liquid composition to produce a viscosity increasing highly refined cellulose mass.

Abstract
Pectinases, such as Pectinex™ Ultra SP-L (composed of the enzyme Polygatacturonase, a type of pectinase which is derived from Aspergillus aculeatus) or pectinmethylesterases were used to decrease or increase, respectively, the viscosity of fiber solutions, especially solutions with highly refined cellulosic thickeners, and particularly those made of highly refined cellulosic parenchyma cell wall fiber solutions. The enzyme can reduce the viscosity up to 95% or increase the viscosity 100 fold. At lower concentrations the enzyme requires up to a few days of reacting to reach the full reduction in viscosity. Pectinex™ Ultra SP-L has an optimum pH of 4.5-5 and a temperature optimum of 40° C. By controlling the viscosity available from the dried, treated highly refined cellulosic fiber compositions, tailored powder compositions can be provided that will provide precise viscosities when rehydrated in solutions at a constant concentration.
