Definitions
- the process according to the present invention relates more particularly to the treatment of skins, bladders or the like which contain a large amount of pearl essence and also of fatty matter and conjunctive tissue.
- raw materials can only be decomposed with difliculty by the process specified in the aforesaid patent.
- the said raw material is rapidly altered when in contact with the air, and that it undergoes a physical and chemical change by which it is made continually more resistant to the decomposition by the detersive agents, so that the resulting pearl essence has a rough consistency which precludes its use for the object intended.
- the invention relates to a process for the preservation of the raw material whereby the aforesaid change in density is obviated, and also to a process for obtaining pearl essence from such material, which latter process is based upon the same principle as the said preserving process.
- the said material is immersed in a bath of water containing the proper proportion such as 1 to 5 per cent of an organic or inorganic acid which will gelatinize or at least swell and soften the tissue which serves as a backing for the minute and brilliant crystalloids, and this acid must be chosen among those which have little or no action upon the said crystals, such as formic, tartaric, acetic or other acids.
- a suflicient quantity of a neutral salt Y such as common salt thus affording a solution whose molecular concentration is such that the conjunctive tissue will not be swelled and decomposed.
- the said preserving process comprises by way of example the use of a bath containing 10 to 20 per cent of common salt or sodium chloride to which is added 1 to 5 per cent (or more) of an acid.
- the surplus bath of acid or salt and acid is removed from the material and the latter is then subjected to further treatment for the separation of the crystalloids from the skins, bladders, etc. and for the cleaning of such crystalloids.
- the substances which have thus been treated so as to preserve their properties for a long period may be treated in an approved manner in a detersive bath containing the acids above mentioned, operating at 30-60 C. or above. It is necessary to use a detergent which acts (while maintaining all of its emulsifying properties) in a bath having an acid reaction.
- the whole is raised to a suitable tern perature, and this should not exceed 45 C. when pepsin is added, but it may beheatedto amuch greater degree for instance up to 75 C., if the ferment is added only after a certain time.
- a suitable stirring is employed to subdivide the raw material to the maximum and to set free the brilliant crystals, and the latter can then be removed either by a natural settling or preferably by the centrifugal or other mechanical process.
- a ferment may thus be added after the action of the detersive agent, or
- the essential principle consists in the combined use of an acid which will dissolve the conjunctive tissue, with or without the use of a ferment or a detersive agent adapted to emulsify to the maximum degree, while separating them, the crystalloid substances which constitute the pearl essence.
