Adjusting the physical chemical composition of food by reducing water content or adding water activity-lowering agents. 

Although all foods must be labelled with the additives they contain, few comprehensive data are available about which specific, branded foods contain which additives. The Irish National Food Ingredient Database7 (INFID) provides data about food additives present in specific food products available in the Irish market. Although many of the branded foods are the same as those available in other markets, the exact composition of foods may vary from country to country, depending on local regulations, product availability, national preferences, etc. Extrapolation from the INFID must therefore be done with caution. 

The New Chemistry is a set of six hooks intended to provide an overview of some areas of research not typically included in the beginning middle or high school curriculum in chemistry. The six hooks in the set—Chemistry of Drugs, Chemistry of New Materials, Forensic Chemistry, Chemistry of the Environment, Food Chemistry, and Chemistry of Space—are designed to provide a broad, general introduction to some helds of chemistry that are less commonly mentioned in standard introductory chemistry courses. They cover topics ranging from the most fundamental helds of chemistry, such as the origins of matter and of the universe, to those with important applications to everyday life, such as the composition of foods... 

Consequently, the aims in this chapter are to critically examine the available literature on the flavonoid composition of foods and to establish a food flavonoid database, which can be continually expanded as more information becomes available. By using predetermined selection criteria to ensure critical assessment of data quality, the intention is to provide researchers with an improved resource for use in studies exploring the relationships between flavonoid intake and health as well as highlighting important food groups where flavonoid content data are currently lacking. 

Secondly, the study of the chemical composition of foods and of its changes on processing are not the only aim (except in control analyses) the space of chemical quantities is intermediate between the cause space, which includes every parameter affecting food composition, and the effect space, where we find variables related to food properties, its quality, sensorial evaluations, nutritional value, and storage possibilities. Generally, the chemical space is described accurately and concisely. 

In the majority of the studies on the composition of food aromas, AEDA is used for the determination of the relative odour potency of the compounds detected by GC-O (reviewed in [1]). The odour potency is proportional to the odour activity value (OAV) of the compound in air. The OAV is defined as the ratio of the concentration of a compound to its odour threshold [3].
