A capsule, especially for preparing a beverage from beverage powder, in particular of coffee from coffee powder, by introducing water into the capsule, wherein the capsule comprises a compacted pellet made of a powder containing at least one polysaccharide, wherein the compacted pellet is sheathed with at least one coating layer, wherein the at least one coating layer comprises a cross-linked polysaccharide, wherein the cross-linked polysaccharide can be obtained by cross-linking a polysaccharide with a cross-linking agent without the use of a polyol spacer.

A method for manufacturing such a capsule comprises the following steps: i) preparing a compacted pellet from a powder containing at least one polysaccharide, ii) bringing at least one part and preferably the entire surface of the compacted pellet used in step i) into contact with a solution of a polysaccharide in a solvent or with a dispersion of a polysaccharide in a dispersant, iii) when appropriate, removing of the compacted pellet from the solution or dispersion of step ii), iv) bringing the compacted pellet obtained in step ii) or iii) into contact with at least one cross-linking agent, v) when appropriate, removing the compacted pellet from the solution of step iv) and vi) drying of the compacted pellet obtained in step iv) or v).

The present disclosure provides for aqueous, curable binder compositions, as well as articles and products comprising assemblies of matter comprising mineral fibers, synthetic fibers, natural fibers, cellulosic particles and sheet materials comprising the binder compositions disclosed herein.

The present invention relates to an enhanced starch resin composition, methods of making the enhanced starch resin composition using environmentally benign, water-based processes, and products produced using the enhanced starch resin composition. The enhanced starch resin composition comprises a native starch and/or a waxy starch crosslinked with a multi-functional polycarboxylic acid. The starch resin composition is formed by a water-based reaction comprising using a non-toxic, water-soluble catalyst to catalyze esterification of the native starch and/or the waxy starch with the multi-functional polycarboxylic acid, thereby yielding a crosslinked starch resin composition having at least one enhanced mechanical property and/or reduced moisture absorption as compared to the native starch and/or the waxy starch.

The present invention relates to new aqueous curable binder compositions comprising a carbohydrate compound, a first cross linker and a second cross linker different from the first capable of undergoing radical polymerization and possibly a free radical initiator.

This patent describes formaldehyde free or formaldehyde reduced binders useful, for example, in a fiber based composite material such as glass or other mineral fiber insulation, non-woven fabric or wood-based board. In one example, melamine is used as an acidic solution or a salt. The salt or solution is used to create an aqueous binder with other components such as a polyol and a crosslinker. A preferred polyol is a nanoparticle comprising high molecular weight starch. In other examples, binders include mixtures of a polyol with urea and a crosslinker. In other examples, a multi-component nanoparticle is made by reacting a polyol such as starch in an extruder with an insolubilizer such as melamine or urea. The resulting particles are mixed with water, optionally with other components such as an additional crosslinker, to create an aqueous binder.

A starch-containing microsphere has a particle size that exhibits polydispersity with uniform distribution in a particle size concentrated distribution interval. The particle size distribution in the particle size concentrated distribution interval has the following features: equal division of the particle size concentrated distribution interval into n intervals, and a microsphere percentage in each interval is formula (I),

[00001]$\begin{array}{cc}\frac{100}{n}\%\pm \frac{10}{n}\%,& \left(I\right)\end{array}$

where n is an integer greater than 1. The preparation method of the starch-containing microsphere includes: first reacting starch with a low concentration of epichlorohydrin, and then reacting the resultant product with a surfactant, followed by final crosslinking to give microspheres. The starch-containing microspheres thus prepared are polydisperse starch-containing microspheres with a uniform particle size distribution, with the particle size being in a range of 0.1-500 μm.
