Absorbing pesticides

Absorbing pesticides

Graham Matthews, Emeritus Professor at Imperial College, is an able communicator. He has taken a topic, pesticides in agriculture, which many will assume prima facie to be dry, technical and of interest only to a few specialists, and has demonstrated that it is both a fascinating subject and one that can be presented in an engaging and informative way. His book, A History of Pesticides, provides an intellectual journey through the topic of agricultural pesticides and it is one for which Professor Matthews is both a knowledgeable and authoritative guide.

Application of ultrasound

Ultrasound in food processing

The preface to this book explains why ultrasound processing is becoming more important in the food industry. It can be used at higher powers to create changes in structure, temperature increases, homogenisation and food preservation, while at lower powers it can be used for process monitoring and food characterisation.

It is a relatively portable and inexpensive technique compared to some competing technologies. The ability of ultrasound to differentiate between small changes in food structure is also an important feature.
