1. Smell: You can smell the sour and spicy taste of genuine royal jelly with your nose. This smell is very strong. Fake goods don't have this taste, and even smell sweet, similar to the general honey taste. These are all problematic.
2. Status: Real royal jelly, if not deteriorated, is milky white or translucent yellow slurry. If the royal jelly you buy is very thin and there are bubbles floating on the surface, you can generally confirm that it is a fake, because this state is very wrong.
3. Purity: drop royal jelly into alkaline liquid with purity of 20% and stir evenly at room temperature. If it can be completely dissolved, it is true without suspended matter, otherwise it is false.
The above is the introduction of how to choose authentic royal jelly, I hope it will help you.
