Thats test for fats. You dissolve the sample you wish to test in ethanol. Then if it dissolves pour it into water and observe color change. If it goes milky white then fats are present. I guess which ever one would go milky white first or be a dark white would contain more fat.
Make sure to use the same amount of ethanol as your sample.

guyzzz! cn sum1 help me? hw do u plan an xperiment 2 find da energy content of a given food.
Click to expand...
take equal amounts of both food first of all
take equal vol of water in 2 diff test tubes with thermometer in tube
hold 1 food sample under tube n burn it
repeat with other sample
measure temp rise of water
whichever sample causes a higher rise in temp has a larger energy content :)
this is just a basic outline
all u got 2 do is write it down properly
