Japanese Flavoring Agents as Food Additives . In Japan, synthetic flavoring agents are allowed to be used only when they are designated by the Minister of Health, Labour and Welfare as food additives under Ethyl butyrate, a pineapple-banana flavour ester, is an example of the most used esters. Lipases (triacylglycerol acylhydrolase, EC.184.108.40.206) can be used in non-aqueous media as catalysts for ester synthesis and the obtained ester can be labelled as “natural”, meeting the increasing consumers’ demand for natural flavours. Methyl acetate is occasionally used as a solvent, being weakly polar and lipophilic, but its close relative ethyl acetate is a more common solvent being less toxic and less soluble in water. Methyl acetate has a solubility of 25% in water at room temperature. At elevated temperature its solubility in water is much higher. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Many are responsible for the fragrance and flavour of flowers and fruits; for example, isopentyl acetate is present in bananas, methyl salicylate in wintergreen, and ethyl butyrate in pineapples.
Ethyl esters are formed by the reaction of ethanol with a fatty acid. Ethyl butanoate is responsible for apple-like aromas, pineapple aromas and blue cheese aromas.

Ethyl Butyrate has an odor that has been described as sweet and fruity. With banana and pineapple like features Asked in Medication and Drugs , Chemistry , Elements and Compounds , Chemical Bonding Introduction . Many esters have pleasant odors and some of them can even be found in nature. Esters are often used in fragrances or flavoring agents due to their organolepticsproperties.
