Abstract
A process of preserving tissue from one or more plant, fungus or algae species is provided. The process comprises treating such tissue by subsequent steps of (i) incubation with a weak acid solution; (ii) removal of excess acid; (iii) incubation with an aqueous sugar alcohol solution; (iv) removal of excess sugar alcohol; and (v) drying. Also provided is a textile material having a sheet like structure, and characterized in having an average thickness of about 0.2-5 mm and comprising about 2% to about 20% sugar alcohol.
Claims10
A preserved macroalgae tissue material with essentially intact cellular structure comprising a macroalgae and a sugar alcohol, wherein the sugar alcohol is glycerol and wherein the preserved macroalgal tissue is obtained by a process comprising steps and order of:
- a. treating a tissue from a macroalgae with an aqueous weak acid solution to generate a pretreated tissue material;
- b. removing excess acid by rinsing the pretreated tissue material with an aqueous solution;
- c. soaking the pretreated tissue material in an aqueous solution comprising at least one sugar glycerol;
- d. removing excess glycerol to generate a preserved tissue material;
- and
- e. drying the resulting preserved tissue material.
A preserved tissue material having a sheet-like structure with an average thickness in the range of from 0.2 to 5 mm, the tissue material comprising tissue from a macroalgae, the tissue having an essentially intact cellular structure;
- the tissue material further comprising in the range from 2% to 20% (w/w) glycerol.
