Bamboo chopsticks refer to chopsticks made of bamboo. As food contact materials, bamboo chopsticks need to be tested in accordance with the Chinese national standard GB4806.



Bamboo chopsticks GB4806 Food Contact Material Testing Guide:

1. Prepare samples: Prepare a certain number of bamboo chopstick samples to ensure that the samples are representative, and package and label them in accordance with standard requirements.

2. Sensory testing: Conduct sensory testing on bamboo chopstick samples, including testing on appearance, color, smell, etc. Observe whether the surface of the chopsticks is smooth and burr-free, whether the color is normal, whether the smell is pungent, etc.

3. Total migration detection: Soak bamboo chopsticks in a certain concentration of food simulation liquid, and detect the total migration amount in the simulation liquid after a certain period of time. This indicator is used to evaluate the amount of harmful substances that may be dissolved out of bamboo chopsticks during long-term use.

4. Heavy metal content detection: Use certain detection methods to detect the heavy metal content in bamboo chopsticks. Focus on the content of heavy metal elements such as lead, cadmium, and arsenic to ensure that they are within the prescribed limits.

5. Decolorization test: Soak bamboo chopsticks in an ethanol solution of a certain concentration and observe the color change on the surface of the chopsticks. The discoloration test is used to evaluate the possible color transfer of bamboo chopsticks during use.

6. Microbiological index testing: Microbial index testing is carried out on bamboo chopsticks, including the total number of bacteria, total number of molds, coliforms, etc. These indicators are used to evaluate the hygienic status of products and ensure that they will not contaminate food during use.

7. Testing of toxic and harmful substances: Bamboo chopsticks are tested for formaldehyde, plasticizers, heavy metals and other toxic and harmful substances to ensure that the product will not cause harm to the human body during use.

8. Label identification inspection: Check whether the label identification of bamboo chopsticks complies with relevant standards, including product name, production date, shelf life and other information. At the same time, the label should indicate "for food contact use" or similar terms.



Bamboo chopsticks GB4806 food contact material testing process:

1. Select samples: Select two bamboo chopsticks from the production line as samples to ensure that the samples are representative.

2. Prepare the application form: Submit the product quality inspection application form to the testing agency, and prepare the software packaging that requires quality inspection.

3. Communication: The organization will assign full-time personnel to establish contact with you to communicate about quality inspection items, specifications, steps, cycle times, costs and other matters.

4. Send samples: Send the two packaged bamboo chopstick samples to the testing agency.

5. Testing and reporting: After receiving the test sample, the testing agency will complete the test within 3-5 days and issue a report.

6. Check the report: You can check the authenticity of the report based on the report number, etc. on the official website of the testing agency.
