A capsule for preparing a beverage from beverage powder, such as coffee from coffee powder, by introducing water into the capsule. The capsule includes a compacted pellet made of a powder containing at least one polysaccharide. The compacted pellet is sheathed with at least one coating layer that includes a cross-linked polysaccharide. The cross-linked polysaccharide can be obtained by cross-linking a polysaccharide with a cross-linking agent without the use of a polyol spacer. Also disclosed are methods for manufacturing such a capsule.

Provided are coating compositions for, and methods for reducing weight loss and improving the shelf life of, post-harvest edible and non-edible plant matter. In particular, the compositions may include a hydrocolloid polymer, an edible wax, a fatty acid, an edible alkaline component essentially free of morpholine and/or ammonia, and water. The edible alkaline component allows formation of a homogeneous emulsion without the need for any additional emulsifier. The methods include applying the compositions to the surface of plant matter, and more specifically to plant matter having a natural skin, shell or tunic.

The present disclosure is generally directed to a bio-ink system that can be used to print cellularized scaffolds for biomedical applications. In certain configurations, the ink has rheological properties suitable for extrusion-based printing techniques and adipose stem cells infused in the ink remain viable seven days after printing. The ink may comprise a mixture of alginate hydrogels, which provide the structural integrity of the printed scaffolds, and gelatin hydrogels, which support the cell proliferation. Borophosphate glass particles are added to the hydrogel mixture where they release Ca-ions that control the viscoelastic properties of the hydrogel before and after printing. Borophosphate glasses described herein promote significantly better ASC viability than previously employed glasses.
