PACKING HOUSE No. 6. 



The practice at this packing house differs slightly from the others 

 in the portions of the carcasses which are canned; that is, the canning 

 meat is not taken entirely from the fore quarters. It was desired to 

 follow the practice of the company as nearly as possible, and the trim- 

 ming was therefore done, as in the other cases, according to their usual 

 custom. Eight carcasses were taken from the chill room, the left side 

 trimmed as if for canning, and the canning meat run through a sausage 

 mill, thoroughly mixed, and a sample taken for analysis. This sample 

 is designated as laboratory No. 17996. Its composition is as follows: 



Per cent. 



Water 69.33 



Proteids (total) 16. 81 



Proteids, coagulated 12. 69 



Globulins 3.06 



Proteoses, peptones, and gel- 

 atin .. 1.06

The canning meat was placed in water at 10 (50 F.) and heated 

 by means of injected steam. After five minutes the temperature had 

 reached 50 (122 F.) and was boiling at the end of eleven minutes. 

 The boiling was continued for one hour. After boiling, the meat 

 weighed 320 pounds. To each 2-pound can were added 1.5 ounces 

 of the "soup liquor" in which the meat had been boiled. The soup 

 liquor employed (laboratory No. , 17977) weighed 1,500 pounds and had 

 the following composition:
