How do you test food samples?
Prepare a test sample by mixing a small amount of food with distilled water. In a test tube, add 40 drops of the sample liquid and ten drops of Benedict’s solution. Warm the test tube by placing it in a hot water bath or container of hot tap water for five minutes.
What is food safety testing?
Food Safety Testing Laboratories and food companies constantly conduct food safety tests for ensuring that the product produced by them is edible using the microbiological analysis.
How does FDA test food?
FDA does not develop or test products before approving them. Instead, FDA experts review the results of laboratory, animal, and human clinical testing done by manufacturers. If FDA grants an approval, it means the agency has determined that the benefits of the product outweigh the known risks for the intended use.
