What the sim shows
Shake the prepared sample with ethanol, then pour the extract into water. A milky-white emulsion indicates fat; a clear result is negative. Adding water alone is not the complete test. This is a staged procedure, not a timed quantitative assay.
- Left: chosen extract. Right: known fat control. Read the emulsion after the water step.
