Flavor appropriate factors

In an alcohol-free beer, the concentrations of the beer odorants were 5 to 10-fold lower than in the pale lager beer [18] suggesting that the former beer is a very appropriate matrix for the determination of odor thresholds. A determination of the odor thresholds in the alcohol-free beer revealed (Table 15) that, compared to water, the odor threshold of all odorants increased, but to a different extent. For instance, the threshold of (E)-B-damascenone increased by a factor of 2500, while that of HDF was enhanced only by a factor of eight. Odor activity values calculated on the basis of the odor thresholds in the alcohol-free beer (Table 15) now confirmed the significant contribution of HDF to the dark beer flavor. 

In summary, there are a variety of flavor types natural, synthetic, and semisynthetic. Appropriate use concentrations depend on many factors, including product characteristics, such as composition, physical state, shelf life, pH, processing temperature, storage conditions, and reactivity of components. Flavor concentrations also depend on the market sector for which the product is targeted. The age of the user and the mode of use are two examples of user-dependent... 

Protein-based ingredients contribute to the enhancement of food texture, flavor, and eye appeal [130], Functionality of protein ingredients can be enhanced also by enzymatic modifications. The factors influencing the choice of an appropriate enzyme for improvement of functional properties of proteins are as follows specificity of the enzyme, conformation of the protein, pH optimum, presence of activators and/or inhibitors, availability, thermostability, and financial causes. 

The quality of vanilla extracts is determined by several factors, including the following correct storage of the beans prior to extraction, blending of different quality beans as appropriate, degree of comminution of beans, method of extraction, correct storage of the extract, and aging for at least 90 days to ensure full flavor development. 

Inosine monophosphate (IMP, disodium salt) and 5 -guanosine monophosphate (GMP, disodium salt) have properties similar to MSG but heightened by a factor of 10-20. Their flavor enhancing ability at 75-500 ppm is good in all food (e. g. soups, sauces, canned meat or tomato juice). However, some other specific effects, besides the MSG effect , have been described for nucleotides. For example, they imprint a sensation of higher viscosity in liquid food. The sensation is often expressed as freshness or naturalness , the expressions body and mouthfeel being more appropriate for soups.
