Book Description :

This volume results from the Eighth Basic Symposium held by the Institute of Food Technologists in Anaheim, California on June 8-9, 1984. The theme of the symposium was "Chemical Changes in Food during Processing." The speakers included a mix of individuals from academic institu tions, governmental agencies, and the food industry. Twenty speakers discussed topics ranging from the basic chemistry relating to food constituents to the more applied aspects of chemical changes in food components during food processing. It was the intent of the organizers to bring together a group of speakers who could address the chemistry of changes in food compo nents during processing from a mechanistic point of view. As a con sequence, the proceedings of this symposium emphasize the basic chemistry of changes in food constituents from a generic perspective which is intended to provide the reader with a background to address more specific problems that may arise.

Book Description :

Chemical changes that occur in foods during processing and storage are manifold and might be both desirable and undesirable in nature. While many of the processes are carried out intentionally, there are also certain unwanted changes that naturally occur in food and might have to be controlled. Therefore, efforts are made to devise processing technologies in which desirable attributes of foods are retained and their deleterious ef fects are minimized. While proteins, lipids and carbohydrates are the main nutrients of food that are affected by processing, it is their interaction with one another, as well as in volvement oflow-molecular-weight constituents that affects their flavor, color and overall acceptability. Thus, generation of aroma via thermal processing and bioconversion is of utmost importance in food preparation. Furthermore, processing operations must be opti mized in order to eliminate or reduce the content of antinutrients that are present in foods and retain their bioactive components. Therefore, while novel processing technologies such as freezing, irradiation, microwaving, high pressure treatment and fermentation might be employed, control process conditions in a manner that both the desirable sensory attributes and wholesomeness of foods are safeguarded is essential. Obviously, method ologies should also be established to quantitate the changes that occur in foods as a result of processing. This volume was developed from contributions provided by a group of internation ally-recognized lead scientists.

Book Description :

The Control and Standardisation of National Food Quality. There must be very many different opinions as to what this title means. To some people it will mean the control by legislation of additive and contaminant levels in food, to others it may mean the laying down of compositional standards for different food commodities, yet again some may consider that it covers the nutritional quality of the food and the maintenance of an adequate satisfactory diet for the population of the country. I think certainly that it could be all of these things and a glance at the variety of titles of papers which other speakers will be giving later in this symposium illustrates the very wide area which is covered by food quality in its many aspects. I will try only to present to you some of those aspects which are the concern of government in the control of food quality. I will not concern myself with those aspects which are the concern only of the manufacturer and his customer, and here I am thinking of flavour, appearance and physical state, such as whether canned, fresh or frozen. These aspects, which affect the type of products to be marketed, and also the aspects of quality control which set out to maintain the standard that the manufacturer has set himself, are I think outside my province.
