Acidic Environment: Esters in Cosmetics and Food (1 Viewer)

[braindrainedAsh]

Can anyone give me some assistance on this dot point? We have no notes on it and none of my study guides or textbooks answer it.

process information from secondary sources to identify and describe the uses of esters as flavours and perfumes in processed foods and cosmetics

Any help that anyone could provide would be greatly appreciated. Then I could finish my acidic environment summary! Yay, that means I then only have to summarize all of chem monitoring and management, and half of industrial chem!

used in preparation, preservation or as the active ingredient in perfumes, foods, cosmetics. they have a desirable, sweet smell. pentyl butanoate is used as apricot fragrance, pentyl ethanoate as banana fragrance. soaps n cosmetics use lots of benzyl salicylate in their preparation. thats all i can think of.

You probably have that point down by now, but i wanted to reply to something in thanks to the people who replied to my question.

So, esters are responsible for the scent and taste of different aromas in nature such as in perfumes, flowers, fruits and flavouring agents.
For example;
- pentyl ethanoate is banana flavour
- octyl ethanoate is orange flavour
- ethyl methanoate is rum flavour

Industry now develops and manufactures synthetic flavours and perfumes for cosmetics and processed foods.

Artificial flavours are often cheaper than natural extracts and represent little health hazard

And, ethyl acetate (ethanoate) is manufactured for use in industry, as a solvent in nail polish remover, paints and lacquers.
