Antibiotics that are used to treat animals can remain in their milk and pose a health risk to people who consume it. Therefore, it is important to test milk for antibiotics before it is sold or consumed.
There are several ways to test milk for antibiotics. One of them is the enzyme inhibition test. This test is based on the fact that antibiotics can inhibit (slow down) the activity of enzymes that are present in milk.
To conduct an enzyme inhibition test, you must purchase a special kit of reagents. The kit includes test tapes and a solution for staining them. To carry out the test, you need to take a small amount of milk and apply it to the test tape. The tape is then placed in the dye solution and waited for a few minutes. If antibiotics are present in milk, then a zone of inhibition will appear on the test tape - an area where the enzyme could not show its activity.
