The preparation of frozen egg products is universally recognized as an excellent means of conserving eggs which can not be sold in the shell as a first-grade product. So extensive has the business become that 19,286,396 pounds of this material were held in storage on January 1, 1920. Careful studies of frozen egg products, by M. E. Pennington and her colleagues,2 have included studies of the character of the raw material, the equipment and operation of break- ing rooms, and the quality of the product sent into commerce. As a result there has been a marked improvement in the selection of the raw materials used and of the processes of manufacture, with a conse- quent improvement in the quality of the finished products. The examination of these products has been attended with what was sus- pected of being a disparity of results when material of the same 1 The investigation discussed in this bulletin was conducted by the author with the assistance of the following members of the Bureau of Chemistry: M.
