Methyl acetate
Methyl acetate belongs to the class of organic compounds known as carboxylic acid esters. These are carboxylic acid derivatives in which the carbon atom from the carbonyl group is attached to an alkyl or an aryl moiety through an oxygen atom (forming an ester group). Methyl acetate is present in apple, grape, banana and other fruits. Methyl acetate is a flavouring ingredient and it is an ester that, in the laboratory, is synthesized from acetic acid and methanol in the presence of strong acids such as sulfuric acid in an esterification reaction. In the presence of strong bases such as sodium hydroxide or strong acids such as hydrochloric acid or sulfuric acid it is hydrolyzed back into methanol and acetic acid, especially at elevated temperature. Methyl acetate, also known as acetic acid methyl ester or methyl ethanoate, is a clear, flammable liquid with a characteristic, not unpleasant smell like certain glues or nail polish removers. Methyl acetate has characteristics very similar to its analog ethyl acetate. Methyl acetate is used as a solvent in glues, paints, and nail polish removers, in chemical reactions, and for extractions. Methyl acetate is a non-polar (lipophilic) to weakly polar (hydrophilic) aprotic solvent. Methyl acetate has a solubility of 25\\% in water at room temperature. At elevated temperature its solubility in water is much higher. Methyl acetate is not stable in the presence of strong aqueous bases or acids. The conversion of methyl acetate back into its components, by an acid, is a first-order reaction with respect to the ester. The reaction of methyl acetate and a base, for example sodium hydroxide, is a second-order reaction with respect to both reactants Methyl acetate is an ester that is synthesized from acetic acid and methanol in the presence of strong acids such as sulfuric acid in an esterification reaction.

The reaction of methyl acetate and a base, for example sodium hydroxide, is a second-order reaction with respect to both reactants. Methyl acetate is a flavouring agent and can be found in many foods, some of which are apple, grape, banana, orange mint, and ginger.
Methyl 3-(methylthio)propanoate
Methyl 3-(methylthio)propanoate, also known as 3-methylsulfanyl-propionic acid methyl ester or methyl beta -methylmercaptopropionate, is a member of the class of compounds known as methyl esters. Methyl esters are organic compounds containing a carboxyl group that is esterified with a methyl group. They have the general structure RC(=O)OR, where R=H or organyl group and R=methyl group. Methyl 3-(methylthio)propanoate is soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Methyl 3-(methylthio)propanoate is a sweet, garlic, and onion tasting compound found in alcoholic beverages and fruits, which makes methyl 3-(methylthio)propanoate a potential biomarker for the consumption of these food products. Methyl 3-(methylthio)propanoate exists in all eukaryotes, ranging from yeast to humans. Methyl 3-(methylthio)propanoate, also known as methyl beta -methylmercaptopropionate or fema 2720, belongs to the class of organic compounds known as methyl esters. These are organic compounds containing a carboxyl group that is esterified with a methyl group. They have the general structure RC(=O)OR, where R=H or organyl group and R=methyl group. Methyl 3-(methylthio)propanoate is found, on average, in the highest concentration within pineapples. This could make methyl 3-(methylthio)propanoate a potential biomarker for the consumption of these foods.
Methyl propionate
Methyl propionate is a flavouring ingredient. It belongs to the family of carboxylic acid esters. These are carboxylic acid derivatives in which the carbo atom from the carbonyl group is attached to an alkyl or oaryl moiety through an oxygen atom (forming an ester group). Flavouring ingredient
Methyl cyclohexanecarboxylate
Methyl cyclohexanecarboxylate is a flavouring ingredien Flavouring ingredient Methyl cyclohexanecarboxylate is an endogenous metabolite.
Methyl isobutyrate
Methyl isobutyrate, also known as fema 2694, belongs to the class of organic compounds known as methyl esters. These are organic compounds containing a carboxyl group that is esterified with a methyl group. They have the general structure RC(=O)OR, where R=H or organyl group and R=methyl group. Methyl isobutyrate is an organic compound with the formula CH3O2CCH(CH3)2. Methyl isobutyrate is an apple, floral, and flower tasting compound. methyl isobutyrate has been detected, but not quantified, in several different foods, such as fruits, herbs and spices, pineapples, pomes, and potato. This could make methyl isobutyrate a potential biomarker for the consumption of these foods. Found in various fruits, e.g. apple, banana, kumquat peel, wild blueberry, strawberryand is also present in French fried potato, dill herb and Russian champagnes. Flavouring agent.
