Some people claim they can upon command recall specific odors, others think not and argue that such memories consist only of sensory attributes from other modalities. Unfortunately, there seems to be no simple experimental test of such recall for the simple and basic reason that one can not observe another person’s sensory experiences.
A flavorist will automatically do the same thing—that is, smell the product before tasting it. The reason is, of course, that odor and flavor are two facets of the same sensation. With this in mind, let us discuss the meaning of odor and flavor, examining in particular some of the latest knowledge in the field. The importance of smelling in the evaluation of a flavoring material will become apparent.
The basic question is “do we need flavors at all?’ I think this is the question that regulatory agencies are asking, The issue of natural vs. artificial is a front. The second question is ’’do we really need this endless variety of flavors?” It would be much easier if we only had five or six. We could test them at every level and every combination. I will cover some old ground answering these two fundamental questions.
The ultimate purpose of our products and the reason for our industry, to provide consumers with products which please their taste or smell, today and for generations to come has not changed. Safety has always been and will continue to be our most fundamental concern. We are known to respond to problems long before government regulations can be or have to be enacted. Our technology points toward a bright future for the fragrance and flavor industry.
This paper describes the direct, unconventional GC procedure as applied to flavor-scored soybean oils and its potential utility for detecting volatile essences in flower petals.
Here an attempt has been made to portray the kaleidoscopic chemistry of p-menth-3-ene, the most aristocratic member of the p-menthene series.
Paper of the 7th International Congress of Essential Oils, Kyoto, Japan, October 1977.
The first clue to this mystery was probably uncovered by Crocker in 1947. He postulated that the factors responsible for meat flavor are found to a greater extent in the juice than in the fibre. Crocker explained that the majority of the flavor is developed as a result of the thermal degradation of proteins. During the cooking process, amines, acids, sulfur compounds, and phenols are released.
Fragrances and flavors are most often constituted by numerous components, of which certain particularly powerful ones are detected in dilutions of the order of a gram per metric ton and even lower. The increasing importance of these minor components is not always realized by most specialists in our profession. Yet, these minor components constitute a future field for fundamental research and for industrial applications with economic consequences.
The basis of quantitative food identity is the consumption of unavoidable and harmless quantities of flavoring materials in the form of traditional foods. Therefore a comprehensive study is needed of the quantitative occurence of flavoring materials in all common foods, such as fruits, vegetable, meat, seafood, cereals, and spices.
