This book covers many aspects of thermal processing of milk and milk
products with particular focus on UHT processing. It commences with an
overview of the major thermal processing technologies: thermisation,
pasteurisation, extended-shelf-life (ESL), UHT and in-container
sterilisation. It discusses the principles of the technologies, the
processing and packaging equipment used, processing issues such as
temperature-time profiles, heat stability, fouling and cleaning, and the
quality and safety aspects of the products produced. It provides a
balance of the engineering aspects of the processes and the chemical,
microbiological and sensory aspects of the products. The changes that
occur in products during processing and storage, and the related defects
which can arise, are central to the book. The discussions of these
changes will be an aid to industry personnel in identifying the causes
of quality defects in these products and devising measures which can be
taken to eliminate or minimise the defects.
