Flavor Bites: Hexanoic Acid

Hexanoic acid is found widely in nature and contributes to a smorgasbord of different flavors, containing some of the cheesy profile of butyric acid, but also some of the goaty allure of octanoic acid.

Flavor Bites: Octanoic Acid

Characterized by a cheesy aroma, this ingredient pairs seamlessly with a variety of non-dairy flavors.

Flavor Bites: iso-Butyric Acid

Exhibiting a complex character, iso-butyric acid is effective in a wide range of fruit and non-fruit flavors, particularly those outside of the dairy category.

Flavor Bites: 2-Phenylacetic Acid

Fruit, nut, savory, alcoholic and other flavor uses.

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.

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.
