Ask for advice that 1. There is a method to test the formula that has been successfully inserted. กันเสีย is already set how effective it can be. or use any tools Is it easy to do it yourself? 2. If you can't test it yourself, you have to send it to check where and how.

Hello, for inoculation you will need a lot of equipment. If you do not have previous inoculation experience I strongly do not recommend doing it yourself. An easy way is to import baking, for example, bake in ตู้อบ incubator or ตู้อบเพาะเชื้อ 40 degrees over several weeks. by this temperature It will help the bacteria grow well, which means if there is infection in the formula and สารกันเสีย in the formula is out of control It will show clearly, but this method, if not added to the formula. It's just a test that from our normal production process including สารกันเสีย that we use in formula Is there cleanliness + suitability or not? There may be germs added to our products. For example, if the user opens the lid and use your hands to dip into the product Such testing will not be covered in this case.
