Abstract
The present invention relates to solid compositions comprising a fibrous material of natural origin obtained from plants, wherein the fibrous material comprises micro-scaled and/or nano-scaled fibril agglomerates, and an alditol; a method to obtain such compositions; compositions obtained by this method, products comprising such compositions; and the use of such compositions as formulation aid in such products.
Claims26
A solid composition comprising,
- a) a fibrous material of natural origin obtained from plants, said fibrous material containing more than 10 wt.-% xylose referred to the total weight of the fibrous material and the fibrous material comprising micro-scaled and/or nano-scaled fibril agglomerates, wherein
- i. the micro-scaled fibril agglomerates have an average length in the range of 500 nm-1000 μm,
- ii. the nano-scale fibril agglomerates have an average length in the range of 10 nm to 500 nm;
- and
- b) one or more alditols;
- wherein the BET specific surface area ratio of the solid composition re-dispersed in water to an aqueous suspension of the never dried fibrous material is higher than 0.75.
A method to obtain a solid composition, the method comprising the steps of:
- a) Providing a suspension of a fibrous material of natural origin obtained from plants, wherein the fibrous material comprises micro-scaled and/or nano-scaled fibril agglomerates, wherein the micro-scaled fibril agglomerates have an average length in the range of 500 nm-1000 μm, wherein the nano-scale fibril agglomerates have an average length in the range of 10 nm to 500 nm, and wherein the fibrous material contains more than 10 wt.-% xylose referred to the total weight of the fibrous material;
- b) combining one or more alditols with the suspension provided in step a) in order to form a mixture;
- and
- c) Before or after step d), adding to the mixture obtained in step b) respectively to the mixture obtained in step d) one or more polymer additives, one or more functional ingredients or a combination thereof;
- and
- d) Drying the mixture by applying a drying method involving heat, electromagnetic waves and/or vacuum in order to form the solid composition.
(canceled)
A solid product comprising a solid composition that comprises
- a) a fibrous material of natural origin obtained from plants, said fibrous material containing more than 10 wt.-% xylose referred to the total weight of the fibrous material and the fibrous material comprising micro-scaled and/or nano-scaled fibril agglomerates, wherein
- i. the micro-scaled fibril agglomerates have an average length in the range of 500 nm-1000 μm,
- ii. the nano-scale fibril agglomerates have an average length in the range of 10 nm to 500 nm;
- and
- b) one or more alditols;
- wherein the BET specific surface area ratio of the solid composition re-dispersed in water to an aqueous suspension of the never dried fibrous material is higher than 0.75,
- and wherein the product is soluble or dispersible in a liquid.
A liquid or gel-like product comprising a solid composition in dispersed form, the solid composition comprising
- a) a fibrous material of natural origin obtained from plants, said fibrous material containing more than 10 wt.-% xylose referred to the total weight of the fibrous material and the fibrous material comprising micro-scaled and/or nano-scaled fibril agglomerates, wherein
- i. the micro-scaled fibril agglomerates have an average length in the range of 500 nm-1000 μm,
- ii. the nano-scale fibril agglomerates have an average length in the range of 10 nm to 500 nm;
- and
- b) one or more alditols
- wherein the BET specific surface area ratio of the solid composition re-dispersed in water to an aqueous suspension of the never dried fibrous material is higher than 0.75.
