Provided herein are mycelium materials and methods for production thereof. In some embodiments, a mycelium material includes: a cultivated mycelium material including one or more masses of branching hyphae, wherein the one or more masses of branching hyphae may be disrupted or pressed and/or a bonding agent may be combined with the cultivated mycelium material. Methods of producing a mycelium material are also provided.

Ultra-stable aqueous foam comprises hydrophobic silica particles residing within bubbles in an aqueous solution of a hydrophilic polymer, a protein, or aqueous dispersible colloidal particles. The combination of the hydrophobic and hydrophilic components stabilizes the foam interfaces to result in long term stability of the foam. The foams can be crosslinked to stable monolithic foams and used for structural foams, coatings, and thermal insulating for construction.

A method and product comprising mixing at least one oil to a converted methylcellulose polymer to result in a methylcellulose polymer-oil mixture, mixing at least one hydrocolloid to the methylcellulose polymer-oil mixture and heating the methylcellulose polymer-oil mixture to result in a microgel structure; and entrapping at least one flavor potentiator within the microgel structure to result in a peptide-infused microgel structure.

An open-cell biodegradable foam material selected from cellulose and polylactic acid having a structure capable of supporting stems of cut flowers and process for its production.

The present disclosure relates to a three-dimensionally (3D) printed tissue engineering scaffold for tissue regeneration and a method for manufacturing the 3D printed tissue engineering scaffold. The 3D printed tissue engineering scaffold may be fabricated at least in part from a composite material having an insoluble component and soluble component. The three-dimensional tissue scaffolds of the disclosure may be fabricated via a rapid prototyping machine. In some instances, the three-dimensional shape of the fabricated tissue engineering scaffold may correspond to a three-dimensional shape of a tissue defect of a patient.
