paper.
-> Sprinkle tea leaves on wet filter paper.Pink or red spots on
papershow colour.
COFFEE-
-> Gently sprinkle the coffee powder on the surface of water in
glass.The coffee floats over the water but chicory begins to
sink down within a few seconds.The falling chicory powder
leaves particles behindthem a trail of colour,due to arge
amount of caramel they contain.
HONEY-
-> A cotton wick dipped in pure honey burns when ignited with a
matchstick.Ifadulterated it willnot burn or if it does it will
produce a cracking sound.

7. • MILK-
->Put a drop of milk on polished vertical surface.The drop of pure milk either
stops or flows slowly leaving a white trail behind it.Milk adulterated with
water will flow immediately without leaving any trace.
->Add a few drops of iodine to the sample.Appearance of bluish black colour
indicates the presence of starch.
->Take 5ml of milk in a test tube and add 2 drops of bromothymol blue
solution.Development of blue colour after 10 minutes indicate the presence of
urea.
SWEETS-

indicates the presence of starch.
SUGAR-

MUSTARD SEEDS-
->Argemone seeds have rough surface.Mustrad seeds on pressing shows yellow
inside while argemone seed is white.
->Add nitric acid to the sample.Heat for 2-3 minutes.If red colour
appears,adulterant is present.

10. a)Buy standard goods like those with
ISI,AGMARK or FPO marks.They indicate that
the products are genuine.
b)Buy reliable brands from standard companies.
c)Before buying an article,note the
standardisation mark, manufacturing and
expiry date as well as the price.
d)Study the label properly to get complete
details of the product.
e)If you find a shpokeeper indulging in
adulteration,boycott the shop and report the
matter to the concerned authorities.
f)Do not buy loose foodstuffs from roadsides
but buy only packed ones.There are more
chances of adulteration fro loose foodstuffs.
