Argues that the Republican hold on government is not a reflection of a wholesale electorate realignment, but simply a slight edge over the Democrats.

Effective mixing of aroma compounds into complex food materials often requires the use of a flavor solvent. Solvents such as propylene glycol and triacetin aid the dispersion of small quantities of aroma compounds into foods either through enhancing mixing phenomena, changing partition coefficients or by delivering small droplets of aroma enriched solvent to the product. Within this chapter, the choice of flavor solvent is shown to impact the microstructure of shortcake biscuits.

Oil bodies are small sub-cellular organelles found in oilseeds that store oil as stabile oil droplets. There is the potential to directly extract and use oil bodies as a food ingredient; as such, the impact of their addition on the nutritional value and quality attributes of food should be assessed. This chapter reviews previous studies by the University of Nottingham on the complex and dynamic association of aroma volatiles and oil bodies, and highlights the impact of the oil body structural matrix on the equilibrium and static delivery of 2-nonanone to the gas phase.

Prediction of the impact of lipid addition or subtraction on the aroma profile of a complex food is challenging. There are simple models for modeling the impact of changes in lipid content on aroma partitioning, which are designed and validated for static equilibrium headspace situations but are not appropriate for dynamic in vivo situations. This chapter reviews work completed at the University of Nottingham on the development and application of a mathematical model to predict the impact of lipid modification on the delivery of aroma in vivo.

Food flavour technology is of key importance for the food industry.Increasingly, food products must comply with legal requirements andconform to consumer demands for “natural” products, butthe simple fact is that, if foods do not taste good, they will notbe consumed and any nutritional benefit will be lost. Thereis therefore keen interest throughout the world in the production,utilisation and analysis of flavours. The second edition of this successful book offers a broadintroduction to the formulation, origins, analysis and performanceof food flavours, updating the original chapters and addingvaluable new material that introduces some of the newermethodologies and recent advances. The creation of flavourings is the starting point for the book,outlining the methodology and constraints faced byflavourists. Further constraints are considered in a chapterdealing with international legislation. The origins of flavours aredescribed in three chapters covering thermal generation,biogeneration and natural sources, keeping in mind the adjustmentsthat manufacturers have had to make to their raw materials andprocesses to meet the demand for natural products whilst complyingwith cost issues. Delivery of flavours using encapsulation orthrough an understanding of the properties of the food matrix isdescribed in the next two chapters, and this section is followed bychapters describing the different ways to analyse flavours usinginstrumental, modelling and sensory techniques. The book is aimedat food scientists and technologists, ingredients suppliers,quality assurance personnel, analytical chemists andbiotechnologists.

With record low approval ratings (the lowest poll results since 1974) Congress is a failing institution in the eyes of many Americans. Is public opinion correct in judging the inefficacy of the legislative branch, or is the public mistaken in these harsh criticisms? Congress: A Performance Appraisal teaches students about this critical institution of American democracy by examining how successful the body is in carrying out its key functions, particularly representation, lawmaking, and checking the other branches of government. Rather than focusing on the institutional and procedural questions of how Congress is set up, what rules guide its actions, and how its members carry out their daily duties, Andrew J. Taylor asks: do these structures, procedures, behaviors, and outcomes serve the American people as they were meant to? Using a set of aspirations, a good legislature should strive for and benchmarks to rate how close it comes to those aspirations, Taylor offers a unique approach to the discussion of Congress, its actions, and its efficacy as a legislature. Sure to prompt provocative classroom discussions, Congress is the perfect text for courses on American government and politics.
