Fat Content Testing in Foods

The video tutorial, led by Asr Oktavia Putri, demonstrates a simple science experiment to test for fat content in various substances. The experiment begins with a comparison of fat presence in water and cooking oil using brown paper. The paper is observed for any residue left by the substances. The tutorial then extends the test to eight different food items, including peanuts, coconut milk, and corn, to identify which contain fat. The results are analyzed based on the residue left on the paper, indicating the presence of fat.
