Production of glucosamine from plant species
View Patent ↗The present invention relates to a process for generating glucosamine from plants wherein fresh plant materials, or re-hydrated dried plant materials or plant extracts, are heated at a temperature comprised between 70 and 110° C. for more than 10 hours, characterized in that a fertilizer acting as glucosamine precursor is added during the cultivation of the plants, before the harvest.
1. A process for generating glucosamine from plants, the method comprising:
adding a nitrogen-based fertilizer that acts as a glucosamine precursor during cultivation of a plant material, before harvest, wherein the plant material is a plant species belonging to a genus selected from the group consisting of Cichorium, Daucus, Helianthus, Beta and combinations thereof;
harvesting the plant material; and
heating the plant material in a form selected from the group consisting of non-dried plant materials, re-hydrated dried plant materials and plant extracts, to a temperature of between 70 and 110° C. for more than 10 hours, and less than one week to generate glucosamine from the plant material.
2. The process according to claim 1 wherein the fertilizer is a compound that allows the formation of a sugar-nitrogen compound condensation required to form glucosamine.
3. The process according to claim 1 wherein the plants are selected from the group consisting of chicory ( Cichorium intybus ), carrot ( Daucus carota ), Jerusalem artichoke ( Helianthus tuberosum ), and beet ( Beta vulgaris ).
4. The process according to claim 3 wherein chicory is produced in hydroponic conditions.
5. The process according to claim 4 wherein the fertilizer is added in a nutritive solution for a hydroponic cultivation of chicory roots before or after production of endives.
6. The process according to claim 5 wherein the resulting chicory roots of the endive production are used as a source of glucosamine.
7. A process for generating glucosamine, the method comprising:
cultivating a plant material in a hydroponic culture system;
adding a glucosamine precursor comprising a nitrogen-based fertilizer during cultivation of the plant material, before harvest, wherein the plant material is a plant species belonging to a genus selected from the group consisting of Cichorium, Daucus, Helianthus, Beta and combinations thereof;
harvesting the plant material; and
heating the plant material to a temperature of between 70 and 110° C. for more than 10 hours and less than one week to generate glucosamine from the plant material.
8. The process according to claim 1 wherein the fertilizer is ammonium salts.
9. The process according to claim 7 wherein the fertilizer is a compound that allows the formation of a sugar-nitrogen compound condensation required to form glucosamine.
10. The process according to claim 7 wherein the fertilizer is ammonium salts.
