DAIRY SCIENCE AND FOOD TECHNOLOGY

 


ACKNOWLEDGEMENTS

The author wishes to acknowledge the use of material produced with former colleagues on International Dairy Federation Group IDF F19, 'Indigenous antimicrobial proteins in milk' in particular Professor Lennart Bjorck (SE), Dr Ir. J Stadhouders (NL) and Professor Dr W Heeschen (DE).

Group F 19 was initiated at the annual sessions of IDF at Montreux in 1979. The first meeting of the group was held in June 1982. The work of the group was initially focused, after a request in 1982 from the Joint FAO/WHO Committee of Government Experts for technical advice from IDF on the use of the lactoperoxidase system for preservation of raw milk. This work resulted in a "Code of Practice", which was published in 1988 (Bulletin of IDF No. 234/1988).

In 1985 the International Dairy Federation (IDF) published a monograph the "Protective proteins in milk: biological significance and exploitations" (IDF bulletin No. 191, 9985) authored by Dr Bruno Reiter. In the same year, IDF through Group F 19 "Indigenous antimicrobial proteins in milk" working in collaboration with the Federation of European Microbial Societies (FEMS) organised a symposium titled "Antimicrobial systems in milk". The proceedings from this symposium were published jointly by the IDF and Bath University Press (1986). The author, deputy chairman of F19, presented a paper on behalf of the Group entitled"Significance of the Antimicrobial Proteins of Milk to the Dairy Industry" at the IDF Cheese Week at Rennes, France 1988. This draft document formed the basis of a more extensive monograph entitled the 'Significance of the indigenous antimicrobial agents of milk to the dairy industry' published by IDF in 1991 (IDF bulletin . 264/1991). More recently a monograph,'Determination of indigenous antimicrobial proteins of milk' (IDF No. 284/1993), detailing methods for the analysis of these antimicrobial proteins in milk was published.

These IDF documents give a detailed summary of the basic properties and mechanisms of the antimicrobial systems in milk and also provide an excellent overview of the more commercial aspects of the antimicrobial agents of bovine milk.

The author gratefully acknowledges collaborative work with former colleagues Dr Bob Crawford, Dr Bo Ekstrand, Dr Nigel Wade, Dr Tony Waterhouse and the late Mr Arthur Walker. Arthur died in 2002 and had a very positive professional influence on me. He was a person dedicated to the education of young people and had an extraordinary positive attitude to life. Arthur isolated many of the bacteriophages that were in the Auchincruive phage collection when I went to Scotland in 1977. Most of these had been isolated from technical investigations of slow-acid problems with single-strain starters such as C2 at the then SMB factories at Stranraer and Dalbeattie. Hence my designation of the C2 phage that I studied as part of my PhD, as ØC2(W).

Some of the work on phage enumeration was undertaken at University College Cork Ireland working with Professors Charlie Daly and Pat Fox. Their generous help and advice over many years is gratefully acknowledged.
