Method according to claim 1, wherein the food composition is enriched in isoamyl acetate to have an amount of isoamyl acetate of 0001 μg to 1,000,000 μg per 100 g of the food composition 12 method according to claim 1 , wherein the food composition is a beverage containing isoamyl acetate in an amount of 0001 μg to 1,000,000 μg per 100. Isoamyl acetate, which smells like bananas, is also an alarm pheromone released by honey bees when they sting an intruder the pheromone attracts other bees and incites them to attack the intruder for these reasons, fragrances are more often.

Preparation of isoamylacetate

Isoamyl acetate is an organic compound that is the ester formed from isoamyl alcohol (we used pentanol in our experiment) and acetic acid has a strong odor which is also described as similar to both banana and pear. Isoamyl acetate is a natural flavour ester, widely used as a source of banana flavour by the food industry fusel alcohols such as amyl alcohol are produced in significant quantities as a waste product, sometimes referred to as “lees oil” or “fusel oil”, of the alcohol distilling industry. Authors: (sebastian torres, ashok pandey, guillermo r castro, planta piloto de procesos industriales microbiológicos (proimi), tucumán, argentina, and others) abstract: isoamyl acetate is one of the most important flavor compounds used in food industries because of its characteristic banana flavor.

  • Isoamyl acetate, also known as isopentyl acetate, is an organic compound that is the ester formed from isoamyl alcohol and acetic acid it is a colorless liquid that is only slightly soluble in water, but very soluble in most organic solvents.
  • Isoamyl acetate synthesis was carried out in a batch stirred tank reactor made of pyrex glass with an spheric geometry and a capacity of 01 l the reactor containing isoamyl alcohol and n -hexane was placed in a thermostatic bath providing a constant temperature up to 338 ± 01 k with magnetic stirring at 200 rpm.
