Pepsi vs. Coke: The Flavor Differences

Not all colas are identical, as Pepsi and Coca-Cola fans know. The key flavor differences between the competitors are described by Malcom Gladwell in his book, "Blink."

Stability of Beverage Flavor Emulsions

The problems of producing a stable emulsion can be solved by application of colloidal chemistry principles. Factors influencing emulsion stability are: the particle size distribution in the emulsion, density balance of the two phases, adsorption of solid film at interfaces and electrostatic charges on the droplets.

Flavor research: the Perception of Sour Taste

In a recent study, scientists at Monell Chemical Senses Center report that genes play a large role in determining individual differences in sour taste perception

FEMA Addresses Organic Questions

The Flavor and Extract Manufacturers Association released the following letter yesterday (Tuesday, January 23) concerning the confusion surrounding the use of flavors as ingredients in “organic” and “made with organic” products.

A Neurobehavioral Analysis of I-Amino Acids as Taste Stimuli

We have described several aspects of amino acid gustatory stimulation in this report. Most convey the same message: despite some peculiarities in response time courses, amino acids bear striking similarities to the salts, acids and sugars which the majority of investigators use as taste stimuli. By determining the gustatory properties of amino acids, future research into nutrition and food selection may proceed in a logical fashion through several levels of nutrient complexity and at successive levels of the nervous system.

Pyrazine Generation from the Maillard Reaction of Mixed Amino Acids in Model Systems

In the present study, we used Kuo et al.’s previously reported selective purge-and-trap methods to study the effect of four amino acids, acting singly or in combination, on the generation of pyrazines.

Natural Source Testing for Flavors and Fragrances

In highly regulated marketplaces where mislabeling could have legal and commercial repercussions, a reliable natural source test is critical at the procurement, research and development, product launch and supply stages.

Minimizing Flavor Deterioration

Flavor deterioration during storage is of interest to both the food and flavor industries. While there are numerous studies on flavor deterioration in foods, little has been published on the deterioration of food flavorings, especially when in the liquid form.

Vanilla flavor is dominated by phenols and their transformation products mostly derived from enzymatic hydrolysis of the phenyl-β-D-glucosides. Cocoa bean flavor is dominated by Strecker aldehydes and pyrazines and other products generated during the roasting process of the beans.

Extracting the Essence: Comparing Vanilla and Cocoa Processes

Understanding the similarities and differences in biochemistry, chemistry and curing processes of vanilla and cocoa may offer insight into producing high-quality materials.
