Esters are substances or organic compounds that typically contain hydrocarbons that served as replacement for the hydrogen molecules. Â In order for a compound to be classified chemically as an ester, it must have similar properties and composition to that of the standard ester functional group. Â Compounds that are referred to as esters are also known to be very aromatic. Â This simply means that these compounds emit a distinctive smell whenever in close proximity to people. Â Most esters are said to have fruity aromas because of the hints of different fruits when smelling them. Â An ester named isoamyl acetate for example is said to have a banana-like aroma while another ester in the form of octyl acetate has an orangey smell. Â Other esters meanwhile have pineapple, pear, apple, peach, honey, or honey aromas among many others. Â All these aromas are considered natural for esters and these are produced by the combination of the compound’s carbocilic group and alcohol.
With different types of alcohol mixed with the carbocilic group, different ester aromas can also be produced. Â This explains why some esters smell like bananas while others emit the scent of other fruits. Â As for chemical experts, most esters are known to produce pleasant smells and aromas. The aroma of esters makes them very useful agents in terms of flavoring for various beverages and other products. Â Some beer products for example make use of certain esters to add a fruity scent and flavor to the beverage. Â There are also cases wherein esters are used as the main flavoring hints of some food items. Â Food experts always point out that taste is closely related to smell and when it comes to food items, having a pleasant and fruity aroma provided by esters is a great plus-factor for the perception of good taste. Â Despite its association with aromatic smells though, esters are not typically used in the perfume industry. Â This is due to the fact that they lack the stability when they come in contact with the sweat on human skin.
