Flavor Bites: Lauric Acid

Though largely used in dairy flavor applications, lauric acid with its mild long-lasting taste effect and mild odor can also be used in a range of savory, fruit and fermented flavors.

Flavor Bites: 2-Methyl Butyric Acid

Use in berry, fruit, brown, fermented and savory flavors

Resin Acid in Tree Moss Extract

Lichens are symbiotic organisms of fungi and algae. The biological significance of lichens and their metabolites has been reviewed by Huneck, who even stated that “good perfumes require lichen extracts.”

Aleuritic Acid in Perfumery and Pheromones

The brief account given above indicates the vast potential which aleuritic acid holds in the synthesis of numerous useful organic compounds possessing olfactory properties. With a steady and substantial availability of threo aleuritic acid, its utility is expected to increase enormously.

Flavor Bites: cis-3-Hexenoic Acid

Application in berry, fruit and other flavors.

Fragrant Esters of 3-Cyclohexylbutanoic Acid

Thus, the acid is not too easily available, but remarkable fragrant properties of its esters raise the interest in its production. The first four stages of its synthesis have been described previously. Prin’s reaction of α-methylstyrene with formaldehyde yields 4-methyl-4-phenyl-1,3-dioxane.

Flavor Bites: 5-Hydroxy 2-decenoic acid delta lactone

Otherwise known as massoi lactone—the key flavor component of massoi bark oil—5-hydroxy 2-decenoic acid delta lactone is known for adding a creamy note in more than just dairy flavors.

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.

Butyric Acid in Dairy, Fruit, Savory, Brown and Other Flavors

Despite this pungent profile, butyric acid is capable of working in a very wide range of flavors.

Synthesis and Aroma Properties of Bis 1,1 and 2,2 (Methylthio) Alkanes

In the current study, we synthesized two series of bis (methylthio) compounds that have not been described in the flavor literature before. The character is distinctly different from that of the reactants, and some interesting fruity and vegetable aromas were obtained.

iso-Valeric acid makes a subtle, but very useful, contribution to hazelnut flavors at 100 ppm.

iso-Valeric Acid in Dairy, Brown, Nut, Savory, Alcoholic Drink & Fruit Flavors

The profile of iso-valeric is very much stereotypical of the primary cheese odor, without any hint of the faint goaty character that starts to creep into the series of aliphatic acids from six carbon atoms upwards.

In beer flavors, the ideal levels are a little surprising. Light, lager-style, beers can benefit from around 300 ppm, but dark beers work best with lower levels, around 100 ppm.

Decanoic Acid in Dairy, Savory, Fermented, Fruit and Other Flavors

Decanoic acid is pretty much an essential component of dairy flavors, but it can also enhance many other categories.

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.

The panel thought of apple, apricot, grape, pear, plum, peach, strawberry and kiwi, and some tropicals such as mango and papaya for possible applications including methyl-cis-5-octenoate.

Flavor Panelists Evaluate Galangal Root Oil, 9-Decenoic Acid, Difurfuryl Disulfide and More

HESP—A New Essential Oil From the Acid Hydrolysate of Spent Sandal Heartwood

In the present study, the utilization of the spent (exhausted) sandalwood powder from steam distillation as a source of an acid hydrolysate oil is examined. It has been found that hydrolysis of the non-volatile portion of an acetone extract of the spent sandalwood powder with methanolic hydrochloric acid followed by steam distillation gave rise to a new essential oil (1.2% yield) which we have called HESP, the acronym for hydrolyzed exhausted sandalwood powder.

The Chemical Composition of the Leaf Essential Oils from 110 Citrus Species, Cultivars, Hybrids and Varieties of Chinese Origin

We carried out systematic analytical studies on the composition of the leaf oils from 110 citrus species, varieties, hybrids and cultivars of Chinese origin in order to look for new resources for essential oils and provide the systematic chemical-composition data of the leaf oils for the taxonomy of citrus plants.
