In conjunction of SM SAINS SERI PUTERI " 2014 Science & Mathematics Week",group UNKNOWN,prepared a slideshow,explaining about EXAMPLES OF ESTER IN FOOD FLAVOURING .

2. One of them is artificial flavour.
Artificial flavours
: obtained by chemical
: not extract from plant or animal
sources.
There are three different of flavour.

3. • One of the chocolate roll is made by real
chocolate and another is made by artificial
chocolate. Can you guess that which is real and
which is not?

4. Food flavouring mainly
contain of ester which has
a pleasant smell. Artificial
flavouring can be
produced by esterification
from alcohol and acid
(usually a carboxylic acid)

5. i) Buthyl-
butanoate
This ester give a pineapple
aroma which is an organic
compound and formed by
butanol and butyric acid. It
is insoluble in water and a
clear, colourless liquid.

6.  ii) Isoamyl acetate
Isoamyl acetate also
known as isopentyl
acetate which is an
organic compound that
formed from isoamyl
alcohol and acetic acid.
This ester give a strong
banana aroma.

7. iii) Methyl anthranilate
This ester give a grape scent.
It is a clear to pale yellow
liquid and slightly soluble in
water.It is combustible. It is
formed by esterification of
anthranilic acid and
methanol.

8.  iv) Benzyl acetate

9. • v) Ethyl formate
This ester give a raspberries
flavour and it is formed by
esterification of ethanol and formic
acid (methanoic acid) that, snacks
such as potato chips contain
artificial food flavour and food
enhancer. Food enhancer give us
salty taste or sweet taste or sour
taste. The most popular enhancer
is Monosodium glutamate (MSG) or
known as glutamic salt.
