u gotta do the whole fat test......then the test tube or the sample with more turbidity has more fat content
Turbidity is a measure of the degree to which the water looses its transparency due to the presence of suspended particulates.....in this case fat particulates

how do u compare the fat content between two biscuits?
and how do u test for fat in them too co u like have to crush them first or just add ethanol or what?

Take two equal pieces of the biscuits in a test tube, and either crush them or break them into smaller pieces. Add ethyl alcohol to the two test tubes along with water. Tube with colour change first or more has more fat content.

Note that the appearance is cloudy and milky so its better if u say that the tube with the more coludy appearance.

hope this helps

  • The cover in the fruit is called the fruit wall
  • the things inside the cover are called seeds
    there is somethin to your right coming out from the fruit wall (small) this is the stalk



HOPE YOU WILL UNDERSTAND
