Physics · Sedimentation & Separation Principles
In food analytical testing, how is heavy filth (such as sand, soil, and dense particles) separated from organic plant matter?
- 1By sieve diameter fractionation in dry air currents.
- 2By capryl alcohol emulsification to float heavy mineral particles.
- 3By density-based sedimentation using chloroform, where heavy inorganic contaminants sink to the bottom.✓
- 4By utilizing alcoholic froth flotation techniques.
Correct answer
By density-based sedimentation using chloroform, where heavy inorganic contaminants sink to the bottom.
