How to Use This Book
The prudent use of approved food additives continues to be important in the food indus-try in order to provide safe, convenient, quality food products with useful shelf-lives.Developments in processing technologies will minimise the use of additives but theiradvantages continue in certain product formats.
The Food Additives Data Book contains practical information about a wide range of foodadditives. They are organised by functional category such as acidulants, antioxidants,colourings, etc. The priority is to provide useful information for the practising food tech-nologist and student. The function in foods and technology of use in foods sections arelikely to be the most useful ones for each additive in the data book. These illustrate whythe additive finds application in certain food products and how it is used from a practicalpoint of view. Chemical and physical data are provided to help the food technologist inusing the additives. Some brief information on legislation is provided also.
To find information about a certain additive it can be searched for in the table of contents (if the functional category is known) or in the index. The index is extensive andcan be used to locate information about certain foods, synonyms, alternative additives andother topics of interest.
