Taste Thresholds of Butter Volatiles in Deodorized Butteroil Medium
TLDR
In this paper, the authors measured thresholds of 31 volatile compounds found in butter were measured in deodorized butter and thresholds of seven volatiles were tested in fresh butter, including Butyric acid, diacetyl, delta-decalactone, 2-nonanone, gamma-undecal-actone and n-hexanal, oftreported constituents of milk fat.Abstract:
SUMMARY
—Taste thresholds of 31 volatile compounds found in butter were measured in deodorized butteroil and thresholds of seven volatiles were measured in fresh butter. Thresholds of mixtures of each of the major classes of volatile compounds (free fatty acids from C2 through C12, gamma-lactones from C7 through C11, even-numbered deltalactones from C8 through C14 and methyl ketones from C3 through C13 except C12 were determined as well as thresholds of single compounds of these classes. Butyric acid, diacetyl, delta-decalactone, 2-nonanone, gamma-undecalactone and n-hexanal, oftreported constituents of milk fat, had thresholds in butteroil of 0.66, 0.055, 1.4, 7.7, 0.95 and 0.19 ppm, respectively. The threshold of a mixture of free fatty acids from C2 through C12 was 0.55 ppm. Synergistic interactions among methyl ketones and free fatty acids were pronounced and interactions among aldehydes were weak, while interactions among lactones were not apparent.read more

Key odorants in various cheese types as determined by gas chromatography-olfactometry
P.M.G. Curioni,J.O. Bosset +1 more
TL;DR: Cheese odour-active compounds identified by gas chromatography-olfactometry (GC-O) are compiled in nine tables dealing with alcohols, aldehydes, ketones, esters, lactones, furans, nitrogen-containing compounds together with pyrazines and sulphurcontaining compounds, terpenes and miscellaneous compounds, and, finally, aromatic compounds and free fatty acids.

Review: Compounds Involved in the Flavor of Surface Mold-Ripened Cheeses: Origins and Properties
P. Molimard,Henry-Eric Spinnler +1 more
TL;DR: A review of the current knowledge about the compounds that contribute to flavor in mold-ripened cheeses, especially Camembert-type cheese, is presented in this article, where the pathway of formation, sensory properties (odorous notes and perception thresholds), and the quantities of the main volatile compounds encountered in these types of cheeses are discussed.

Relations between cheese flavour and chemical composition
TL;DR: Barlow et al. as discussed by the authors found that WSN, lactic acid and H2S correlated highly with Cheddar flavour, and a reasonable prediction of flavour at 12 months could be made from flavour at 3 months plus HSN plus WSN.

The flavour of milk and dairy products: II. Cheese: contribution of volatile compounds
TL;DR: Nursten and McSweeney as discussed by the authors dealt with the odour components of the flavour of the whole range of cheeses, considering the different chemical classes in turn, methyl ketones, fatty acids, phenols, sulphur compounds, terpenes, α-dicarbonyls and related compounds, esters, amines ond other nitrogen containing compounds and lactones.

TL;DR: It appears from experiments with mixtures of various aldehydes that in the case of certain ratios a masking effect in odor and taste occurs.

Autoxidation of Milk Lipids. III. Effect on Flavor of the Additive Interactions of Carbonyl Compounds at Subthreshold Concentrations
TL;DR: In this paper, the additive threshold values for carbonyl compounds in homogenized milk were determined, defined as the interaction of subthreshold concentrations of carbonyls to give a detectable flavor, and the implications of the additive interaction in flavor of foods are discussed.

Contribution of Free Fatty Acids to the Flavor of Rancid Milk
TL;DR: In this paper, the even-numbered fatty acids from butyric to lauric accounted for the fatty acid contribution to rancid flavor and the fatty acids above Lauric acid contributed little, if any, to the rancidity of fresh milk.
