Abstract: “MANUFACTURING PROCESS OF VEGETABLE COLORANT EXTRACTS FROM RESIDUES GENERATED IN THE EXTRACTION AND PROCESSING OF WOOD FROM TROPICAL FOREST SPECIES OF COLORFUL HEARTWOOD”, includes water-soluble vegetable colorant extracts, obtained from residues such as: sawdust, smoothing plane, wood parings and sawing, generated by extraction, processing and manufacturing of wood and/or triturated barks of wood from tropical forest of colorful heartwood, objecting to act on dyeing and coloration of textile fibers, paper, leather, woods and cosmetics, as much as manufacturing of different dyes to several uses. It includes the following steps: a) Manufacturing of water-soluble vegetable colorant extracts from residues of extraction and processing of wood of colorful heartwood of forest species. The extraction is done through aqueous lixiviation, boiling or steam entrainment by circulation of shower or steam. b) Homogenization and condensation of the obtained extracts to increase its atomization.

Abstract: Aqueous solutions of anthocyans are purified by contacting same with a particular, metallic oxide adsorbent, said adsorbent being coated with a thin film of a styrene polymer, and thence by separating the adsorbent and treating it with an eluant. The eluate and the dry, powdery anthocyans which can be obtained therefrom are useful red, blue and violet industrial colorants, especially food colorants.
