They require very small samples, so using it on a sample of a food should work as well. Dipping a spoon in, and rubbing the paper across the back of the spoon should be fine. The only problem I could see is if you food has a deep color (tomato sauce, blackberries, etc). It might be hard to tell the color of the strip through the food coloring. | |
