Compositions and resulting hard capsules comprising hydrophilic coloring foodstuff concentrates

An aqueous composition for making dip-molded comestible hard capsules comprising a film forming capsule base material and one or more colorants each consisting of a hydrophilic coloring foodstuff concentrate.

Cap for a container and related production method

A cap for a container is made of a material at least part of which is derived from natural fibres. The cap comprises a cup-shaped body having a skirt which extends around an axis and a transversal wall arranged transversally to the axis. A cavity is defined inside the cup-shaped body. The cup-shaped body is delimited by an inner surface facing the cavity and by an outer surface facing the opposite way to the cavity. At least one projecting element projects from a surface of the cup-shaped body selected from either the inner surface or the outer surface. At least one recess is provided at the projecting element on another surface of the cup-shaped body selected from either the outer surface or the inner surface.

Structure and method for promoting microalgae growth

An artificial structure for promoting microalgae growth includes a 3D-printed structure formed by positioning a printing surface on a movable stage of a 3D bioprinter in contact with a bio-ink that includes a mixture of a pre-polymer material with one or more of cellulose-derived nanocrystals (CNC), and microalgae cells. By projecting modulated light onto the printing surface while moving the stage, the bio-ink is progressively polymerized to define layers of an artificial coral structure with microalgae cells disposed thereon, where the artificial coral structure is configured to scatter light within the structure.

Super biodegradable straws and method for making the same
12226033 · 2025-02-18 ·

The present invention relates to drinking straws that are made from biodegradable material or bioplastics. The process to manufacture the present invention can use waste lipid wax byproducts. The present invention can incorporate chemical modification of corn or hemp fiber waste, and is comprised of wax byproduct, xanthan gum, carnauba wax and stearic acid. Stearin, hardener and plasticizers are mixed with corn or soy wax. A binder ingredient can be added to the waxes and fiber mixture, resulting in a smooth and hard, durable and biodegradable material with a high melting point. This material is then processed using an extrusion method, whereby the mixed ingredients are forced through an opening in a perforated plate or die with a design specific to form a straw, and then cut into a specific size by blades. The extruder consists of a large, rotating screw tightly fitting within a stationary barrel, at the end of which is the die. Extrusion enables mass production of food via a continuous, efficient system that ensures uniformity of the final product.
