The invention provides a test strip for measuring protein content of a food and a testing method thereof. The test strip comprises a filter strip, a reaction strip, a water-absorbing strip and a substrate, wherein an indicator is adsorbed in the reaction strip and can perform specific reaction with protein in a sample; and the protein content is indicated by color changing. By using the test strip, the protein is tested by a portable color measurement instrument, the testing time is short and is generally less than 30 seconds, the result is accurate and rapid field testing of the protein in the food can be realized. |
