PATENT OFFICE.
THURLOW W. MORGAN AND WILLIAM WIMURRAY, OF CHICAGO, ILLINOIS, ASSIGNOBS 1 1'0 CONTINENTAL CAN COMPANY, 1110., OF NEW YORK, N. Y., A CORPORATION 01? NEW YORK.
PROCESS FOR PREVENTING DISCOLORATION OF CANNED FOODS.
No Drawing.
To all whom it may concern:
can and WILLIAM W. MURRAY, citizens of the United States, residin at Chicago, in
6 the county of Cook and tate of, Illinois,
have invented new and useful Improvements in a Process for Preventing Discoloration of CannedFoods, of which the following is a specification,
The invention relatesto new and useful improvements in a process for preventing discoloration of canned foods.
It is a well known fact that in the processing of many canned foods, there areformed sulphur compounds, which occasionally react either during processing or subsequent thereto, with tin plate metal containers forming dark colored compounds, which are objectionable in appearance. The present invention is directed to a processwhereby the formation of such dark colored compounds are prevented.
Through a series of experiments .with' processing foods in tin cans, it has been found that if an insolublemetallic compound 'of such metal or metals as form sulphides that are not dark colored such as zinc sulphide or cadmium sulphide, is thoroughly incorporated with-the ingredients and homogeneously distributed through a lacquer prior to the application of the lacquer to the surface of the tin plate, so that said compound becomes a component part of the lacquer, the discoloration referred to above is avoided. It has also been found that'it is not'necessary to apply this lacquer hearing the insoluble'metallic compound over' the entire-inner surface of the metal container, but if theends of the container are thus 40 coated,thetdiscoloration is avoided;
In carrying out the invention, an insoluble Application filed May 16, 1925. Serial No. 30,873.
' metallic compound of the character specified Be it known that we, THURLOW W. More.
above is ground to a very fine powder and from one to six per cent of such powder, is mixed with the ingredients forming the lacquer which is to be coated on the metal. By using such a fine powder, it may be so thoroughly incor orated with the in redients as to become omogeneously distributed throughout the entire lacquer. The lacquer is then prepared in the ordinary way and the sheets coated therewith. These coated sheets may be used in making the entire container, or may be used in making the ends or bodies only of the container.
When the insoluble metallic compound is incorporated in the lacquer after the manner above described, it becomes permanently embodied in the lacquer and will be held in placeon the inside of the container during processing and subsequently thereto.
What we claim is- The process of preventing the discolora tion of canned foods comprising providing the inner surface or a' portion thereof, of the metal forming the container for the food, witha lacquer coating having an insoluble metallic compound of such metal or-metals forming sulphides which are not dark colored thoroughly incorporated with the ingredients and homogeneousl distributed through the lacquer prior to t e application of the lacquer to the surface of the metal, so that said compound is ermanently embodied in the lacquer and eld in place on the inside of the container during processing and subsequentthereto.
- In testimony whereof we aflix our signatures.
