The previous chapters examined the process for the development and authorisation of a drug product containing a ne v active ingredient for human use. This represents the most arduous path to market for any medicinal product. This chapter proceeds to examine the process of bringing a veterinary medicinal product to market. While the process shares most of the principles that apply to human drugs, there are some additional features that are unique to veterinary products. These include methods of use and the requirement to evaluate vithdra val periods and maximum residue limits in food-producing species. 

For the production of chemicals, food additives and pharmaceutical products, homogeneous catalysis offers some attractive features such as a high selectivity and activity, e.g. in asymmetric synthesis. However, since most homogeneous catalysts are relatively expensive, their current industrial application is limited [3]. On the other hand, heterogeneous catalysts can easily be separated from the products and can be recycled efficiently. Membrane separations with emphasis on nanofil-tration and ultrafiltration will allow for a similar recyclability of homogeneous catalysts, which is important both from an environmental as well as a commercial... 

In addition to enhancement with essential vitamins, amino acids, and proteins, plants can also be metabolically engineered to produce nutritionally superior carbohydrates and lipids. The relative inexpensiveness as well as the capability to grow large-scale quantities make plant production an attractive feature. In the case of carbohydrates such as starch and sucrose, many products or modifications of these products can be produced on a large scale and at much lower costs than are currently available. For example, trehalose, a food additive, was in the past too costly for large-scale production however, it has now been produced in transgenic tobacco tissue at a much reduced cost. 

Worldwide food trade as well as customers expectations regarding foodstuffs enforce implementation of measures which improve sensory, physicochemical, functional, and health-related characteristics of food products. Food producers themselves, aware of the importance of product quality, do not neglect the question of sensory, visual, and marketing features of food products. This, along with the required economic efficiency, encourages food manufacturers to use various additives in food processing technologies, which improve the characteristics of food products demanded by shoppers. In short, food additives play an important role in today s complex food supply. 

It is worth stressing that everything that has ever been published on the application of AAS to food analysis can be done at least as well with HR-CS AAS. Since the same flames and burners, and the same type of electrothermal atomizers, are used in both systems, and only the spectrometer part from the radiation source to the detector has been re-designed, it is much more appropriate to talk about the improvements brought about by this change, and about the simplifications and the additional features that have become available this way. 

At present there is insufficient reliable scientific data on the adverse effects of food additives in humans but there is much public concern and many anecdotal reports of problems relating to food additives, particularly allergic reactions. The extent of intolerance to food additives in the population at large is, however, only around 3 in 10,000 or, to be more precise, 0.026 per cent). Most of the data available refers to patients who have symptoms such as skin rashes (urticaria). Some of the studies carried out have, however, highlighted certain effects and the same food additives appear to feature in the reports tartrazine and benzoic acid are the most common offenders, especially in relation to h5q>eractivity in children. There may also be cross-reactivity, where an additive causes an effect in a person who has been sensitized by another additive. This can occur between additives and naturally occurring food constituents, for... 

Appreciation of the importance of this process in enhancing the palatability of food has led to the industrial synthesis of Maillard products that feature as synthetic food additives appealing to modem tastes. Some of these have been used in highly flavoured snack foods. 

In Chapters 4 and 6, considerable emphasis is placed on the environmental significance of biotransformation as opposed to biodegradation. It therefore seems appropriate to draw brief attention also to their use in biotechnology. Microorganisms play important roles in widely diverse technical processes ranging from the leaching of ores and the preservation of food, to the production of antibiotics and food additives. It is worth drawing attention to some features of these applications.

Annual plants produce a rich selection of hemicelluloses, often with quite different structures compared with those found in woods, although of course the basic chemical features are always those of polysaccharides. It follows that specific applications are associated with these different structural features, notably as food additives. The presence of charged monomer units is one of the most exploited characteristics, because of the ensuing rheological sensitivity to physical parameters. The properties and appbcations of plant and seaweed hemicelluloses are dealt with in Chapters 13 and 24, the latter dealing with the specific features related to polyelectrolytes.
