Adulteration of Potted Beef.

Оглавление

—From the average data given above it is seen that the principal adulteration in potted beef, assuming that the meat is beef, is starch. Two of the four samples contained starch, one more than 14 percent and one more than 11 percent. The admixture of starch is evidently solely for fraudulent purposes, to increase the weight and bulk with a very much cheaper substance and one for which no necessity for the addition can be claimed. It also increases the quantity of water which the product will carry. Saltpeter was found in one of the four samples and boric acid in two. One of the samples contained a large quantity of tin, due probably to the action of the potted meat upon the tin lining of the can.
