Diacetyl
Diacetyl, also known as 2,3-butadione or dimethylglyoxal, belongs to the class of organic compounds known as alpha-diketones. These are organic compounds containing two ketone groups on two adjacent carbon atoms. Thus, diacetyl is considered to be an oxygenated hydrocarbon lipid molecule. Diacetyl is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Diacetyl exists in all living species, ranging from bacteria to humans. Diacetyl is a strong, sweet, and butter tasting compound. Outside of the human body, diacetyl is found, on average, in the highest concentration in kohlrabis. diacetyl has also been detected, but not quantified in several different foods, such as nances, tartary buckwheats, tamarinds, pineapples, and celeriacs. This could make diacetyl a potential biomarker for the consumption of these foods. Diacetyl is a potentially toxic compound. Diacetyl has been found to be associated with several diseases such as crohns disease, ulcerative colitis, and nonalcoholic fatty liver disease; also diacetyl has been linked to the inborn metabolic disorders including celiac disease. Constituent of butter; formed during fermentation. A common constituent of plant oils, production of breakdown of carbohydrates. Flavouring additive used in food industryand is also present in apple, orange, plum, okra, walnut, Bourbon vanilla, clary sage, soybean, coffee, honey, rose wine, port wine, cocoa and scallop
2,3-Pentanedione
2,3-Pentanedione, also known as acetyl propionyl or pentan-2,3-dione, belongs to the class of organic compounds known as alpha-diketones. These are organic compounds containing two ketone groups on two adjacent carbon atoms. 2,3-Pentanedione is a sweet, butter, and caramel tasting compound. 2,3-Pentanedione has been detected, but not quantified, in several different foods, such as coffee and coffee products, tamarinds, cauliflowers, green beans, and cereals and cereal products. Pentane-2,3-dione is an alpha-diketone that is pentane substituted at the 2- and 3-positions by oxo groups. It has a role as a flavouring agent. It is an alpha-diketone and a methyl ketone. It derives from a hydride of a pentane. 2,3-Pentanedione is a natural product found in Mangifera indica, Carica papaya, and other organisms with data available. 2,3-pentanedione is a metabolite found in or produced by Saccharomyces cerevisiae. 2,3-Pentanedione is a flavouring ingredient. It is found in many foods, some of which are coffee and coffee products, milk and milk products, tea, and fruits. 2,3-Pentanedione is a common constituent of synthetic flavorings and is used to impart a butter, strawberry, caramel, fruit, rum, or cheese flavor in beverages, ice cream, candy, baked goods, gelatins, and puddings. 2,3-Pentanedione also occurs naturally as a fermentation product in beer, wine, and yogurt and is releasedduring roasting of coffee beans[1]. 2,3-Pentanedione is a common constituent of synthetic flavorings and is used to impart a butter, strawberry, caramel, fruit, rum, or cheese flavor in beverages, ice cream, candy, baked goods, gelatins, and puddings. 2,3-Pentanedione also occurs naturally as a fermentation product in beer, wine, and yogurt and is releasedduring roasting of coffee beans[1].
