Materials: Filter paper, wax paper or paper towel Food samples nuts

Materials:
Filter paper, wax paper or paper towel Food samples nuts, Mantequilla, vegetable oil, cookies, pan, Cheese Water Clean plate or surface Procedure:
First, I cut or select small amounts of the foods I want to analyze.
I place each sample on a piece of filter paper or paper towel and press lightly to transfer any fat present in the food to the paper..
I let the paper with the samples sit for about 5-10 minutes so that the grease, if present, is absorbed into the paper.
I reproduce the same procedure with a drop of water on a separate piece of paper., as negative control.
I observe the stains on the paper under the light. If the paper becomes transparent or shows a dark spot, This indicates the presence of lipids.
Record of results: I label each stain on the paper with the name of the corresponding food and note the intensity of the stains.. Foods with higher fat content leave larger and more transparent stains..
