Quality is a composite term encompassing many characteristics of foods. These include color, aroma, texture, general nutrition, shelf-life, stability, and possible presence of undesirable constituents. Obviously deterioration of quality may lead to changes in the attributes that characterize the food in its fresh or freshly processed state. In addition, quality enhancement of products may be carried out using appropriate processing techniques. Interaction of different components present with one another could have a profound effect on sensory quality of products. Meanwhile, presence of extraneous matter such as pesticides and debris may also contribute to a compromise in the quality of foods. In addition, processing often brings about changes in many attributes of food including its nutritional value. Thus, examination of process-induced changes in food products is important. In this book, a cursory account of quality attributes of fresh and processed foods is provided. The book is of interest to food scientists, nutritionists and biochemists in academia, government and industry.

The processing and use of seafood by-products is also covered. This book should be of interest to seafood scientists and technologists; food chemists; biochemists; and microbiologists and sensory scientists in the industrial and academic sectors.
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."
Flavour is an important sensory aspect of the overall acceptability of meat products. Raw meat has a large number of aroma precursors and flavour enhancers which vary according to animal species. This book focuses on the subject of the flavour of meat and meat products. This book should be of interest to food scientists and technologists; and flavour and sensory scientists in industry and academia.
Food and raw material for its production was generally produced via the traditional agriculture. On the other hand, novel chemicals were manufactured in the laboratory or extracted from plant and animal sources. However, as the world population is steadily in creasing, there is a decrease in traditional agriculture productivity and concerns are also expressed over the damage inflicted to the environment and restrictions that might be en forced in food production. At the same time, there is an increasing demand for high qual ity agricultural products as well as for food ingredients related to both the traditional or newly discovered nutrients or phytochemicals. Trends and developments,~n the area of plant biotechnology and bioengineering has allowed manipulation of genes' !lnd/or insertion of new genes, thus production of trans genic plants. Starting from the introduction of agronomic traits, particularly stress resis tance to diverse environmental factors, process and sensory characteristics, food quality and production of novel varieties of plant-based products through genetic engineering, biotechnology is changing the,;agriculture and the concept of production of plant-ba~~d raw materials. Increasing attention is being paid on research for production of plants !pat can provide a wide array of food and non-food products. Perhaps the first non-food pro,d uct that plant biotechnology would achieve is production of large scale custom-designed industrial oils, but the list of chemicals is long, ranging" from oils and specific triacyl glycerols to biopolymers, enzymes, blood components, amo~g others.
A major challenge for the meat and seafood industries continues to be that of pro ducing high-quality, wholesome products. Consumers' demand for reduced-fat, low-fat, and fat-free meats (red meat, poultry, and seafood) with acceptable flavor, texture, and other sensory characteristics or those similar to typical, traditional high-fat meats has im parted further urgency to rising to this challenge. Consequently, meat scientists strive to develop different antemortem strategies as well as to improve on existing postmortem processing technologies in order to meet this consumer demand. While the microbiological quality of meat, meat products, and seafoods is important from a food safety standpoint, it is the physicochemical attributes and the interactions of the various chemical components of muscle and ingredients which directly influence the product palatability and consumer acceptability. Virtually every step in production and processing, including animal dietary regime, antemortem stress conditions, postmortem handling, product formulation, temperature of processing, packaging, and storage, affects the quality attributes of muscle foods."
The ability to regulate and manipulate the generation or remodeling of blood vessels is key to the successful treatment of many chronic diseases, both oncological and non-oncological. Several bioactive compounds present in human diets are now known to exert an inhibitive effect on the either the signaling or construction of new blood vessels. The identification and characterization of these anti-angiogenic molecules opens a new avenue for the research and production of functional and medicinal foods with far reaching implications for the food-based treatment of chronic degenerative disease.

Meat has been treated for centuries with rock salt as a means of
preservation. However, only one century has passed since the German
researchers, Polenske in 1891, Kisshalt in 1899, and Lehmann in
1899, discovered that the active component in the curing process
was nitrite. Soon after the role of nitrite as a meat curing agent
was revealed, government regulators placed guidelines on the level
of nitrite and nitrate permitted for use in cured meat
formulations. In the late 1960s and early 1970s, the development of
the so-called "nitrite problem" surfaced because of the detection
of N-nitrosamines in processed meats. The industry was in an uproar
and the issue was of paramount interest to scientists and the
public. A major technical advance in the analytical technique for
N-nitrosamine detection was achieved when Thermo Electron of
Waltham, Massachusetts introduced the thermal energy analyzer
(TEA). This unit allowed the screening of a large number of samples
for nitrosamine with only a minimum preparation. The role of
nitrite in revealing the desired and unique flavor of cured
products, perhaps by suppressing the formation of lipid oxidation
products was another development in revealing other properties of
nitrite. Above all, the antimicrobial role of nitrite, together
with salt, had a major influence on the popularity of
nitrite/nitrate in food preservation. This book provides a review of the desirable attributes which sodium nitrite confers to meat during processing, as well as drawbacks of nitrite usage, i.e., the presence of N-nitrosoamines. In addition, solutions for the curing of meat without the use of nitrite are presented. An examination of a multicomponent nitrite-free curing system entailing the color, flavor, and microbial protection of such a system is given.
