In the cheese the moisture content was determined and the amount of cheese obtained was quantified. The results at the laboratory level showed that the increase in temperature caused higher denaturation of the proteins, a higher yield and an increase in moisture in the cheese compared to that obtained with raw milk. However, statistically the results showed that the heat treatment does influence the denaturation of the proteins but not the performance of the cheese. Downloads Download data is not yet available.

Perhaps the single most contributing factor to the public health regulatory control of milk pasteurization and safety occurred in , when the state of Alabama initiated a request for assistance from the U. Public Health Service to develop a milk sanitation program. The work between this state and the federal government eventually led to the development of the first proposed Standard Milk Ordinance November 7,Public Health Reports.

This first milk code initiated actions by other interested states and in a uniform national Code was published which included both technical and administrative notes for satisfactory compliance.

This was a major milestone. Now minimum pasteurization standards could be further developed and established on a uniform nationwide basis.

Little did they realize that 25 years later the National Conference would be established from these initial efforts. Developments then flourished.

The first plate heat exchangers were introduced into the U. Earlier in the application of a higher heat process was evolving in Europe. Pennsylvania in conducted studies relative to the thermal destruction of pathogens using oF for a 15 second hold time. Only slight changes were made to the pasteurization requirements in the s.

The edition of the Milk Ordinance and Code, although not requiring pasteurization, highly recommended that cities adopt the Ordinance if permitted in their local codes. This is a febrile rickettsial disease producing flu-like symptoms As a result, the USPHS in cooperation with University of California-Davis recommended increasing the minimum batch pasteurization temperature from o to o F maintaining the 30 minute minimum holding period.

The application of heat to milk for the purposes of preservation, with the extra benefit of the protection of public health, continues to develop.

Innovative methods are now available for processing milk at ultra high temperatures UHT with reduced holding times. Pasteurization systems have become more complex. Methods of concentration have evolved from the mids G. Bordens vacuum condenser to the ultramodern methods of concentration.

One of the latest major developments of the s in the U. Perhaps, now that we have followed the development of pasteurization 15 we must ask another question Most of us have knowledge of at least the basics of the biological sciences and may have advanced degrees in biological sanitary sciences.
