Flavor features

A consumer usually knows what to expect in the flavor of a food and downgrades it when the flavor is unbalanced or in some manner is not representative. If, for example, the characteristics of rawness, such as earthy, starchy, bitter, and sour, are of relatively high intensity in a cooked vegetable, the vegetable will have more negative than positive flavor features. A most important means of shifting emphasis to the positive side is to add salt, along with such flavorful materials as butter and pepper and, as these present studies indicated, possibly a sweet substance. 

Analysis of Off-Flavor Compounds in Food 2,4,6-Trichloroanisole (TCA) in Wine Analysis of flavor compounds in food comprises different approaches (1) target compound analysis focused on the detection and quantification of known compounds responsible for specific flavor features, (2) profiling volatile compounds done either to get a knowledge of food flavor/volatile compounds composition or, aided with multivariate analysis (MVA), for the identification of the origin of specific foods or their adulteration, and (3) sensory-oriented identification and quantification of key odorants (also off-odorants) of particular foods.

Four features of food are recognized to determine acceptance, ie, flavor, nutritive value, appearance, and mouthfeel. When all four aspects are in proper quantitative proportions, a food finds general acceptance. When all four are interdependent, appearance takes precedence over the others. However, a report by the Food Marketing Institute has shown that consumers placed nutrition second to flavor in importance (6). 

Ammonia compounds are a primary chemical component of many reconstituted tobaccos. The importance of ammoniation in the development of the characteristic flavor popularized by Marlboro has been widely pubhcized (Bates et al. 1999 Freedman 1995 Hurt and Robertson 1998). The chemical impact of ammoniation is complex and appears to influence the form and delivery of nicotine in a variety of interconnected ways (see BW Fig. 4) (Johnson 1989). Ammoniated reconstituted tobacco has a characteristic mild sensory profile, and features a number of important compounds created through the reaction between ammonia and sugars (J.R. Reynolds 1980 Wells and Kendrick 1995). Addition of ammonia as a strong base leads to increased smoke pH, which corresponds with increased levels of free nicotine in smoke (Hurt and Robertson 1998). Thus, a 1982 position paper from RJR observed that ... ammonia in smoke is one of the major pH controlling components and that ... studies of the effect of ammonia on smoke composition showed... an increase in physiological satisfaction with increasing ammonia content (Bemasek and Nystrom 1982).

Modest doses of radiation have been shown to inactivate the few residual yeast in heat-pasteurized beer. The major problem here involves flavor and odor. Breweries in common with all branches of beverage-alcohol manufacture jealously guard these features as being of prime importance (J3). 

The less-lhan-scientific ring ascribed lo the comparatively recent discovery of a third form of carbon, the fullerenes. is reminiscent ad flavors used a few years ago to describe the various kinds of quarks In the field of high-energy physics. The technical literature on fullerenes. as of early 1994. features such terms as bucky-ball. buckminstcrfullerene. buckyiube, carbon cage, dopey ball, hairy ball. Russian doll, et al.. some of which termv are synonymous others have specific connotations. Considered as an entity, fiillercne chemistry constitutes a major breakthrough in the science of physics and chemistry of materials al the molecular level. 

There are several flavors of the agile iterative process. The most popular ones are the Rational Unified Process (RUP) (Kruchten, 2003) and Extreme Programming (XP) (Beck, 2004). Other flavors include Scrum (Schwaber and Beedle, 2001), Evo, and Feature-Driven Development (Palmer and Felsing, 2002). The following list of key practices is found in all agile iterative development processes that in my view are the most important. For details, please refer to Larman (2004) and Beck (2004).
