1 depends on the purity of honey. Generally, honey is not added, and there will be some tiny suspended matter more or less. These tiny suspended substances fall from the hive when honey is separated from the hive. But rest assured, this is edible and will not affect your health.
2. Look at the silk pulled by honey. Stir the honey with chopsticks and then pull it out of the honey. The filaments drawn by good honey are very slender, and the honey stuck to chopsticks doesn't look very sticky and flows quickly. The filaments pulled out by honey fall into the honey pot, and quickly merge with the honey in the pot, and the contact surface is flat without too many ripples.
When you stir the honey with additives, you will find that there are more honey attached to the chopsticks and the flow is slow. When it drops into the jar, it will have a ripple and uneven feeling.
3. Look at the bubbles of honey. Similarly, if you stir honey with chopsticks many times, there will be a lot of bubbles in the honey with high purity. If you scoop out bubbles similar to bubbles and put them in another bowl about half an hour apart, the bubbles will turn into honey again (the length of time is affected by season and temperature). But honey with additives and low purity will not have so many bubbles. There won't even be bubbles.
4. Look at the penetration ability of honey. Take a family napkin and put it on the table. Dip a drop of honey with chopsticks and observe it on a napkin. High-purity honey has strong permeability, and will soon penetrate paper and be printed on the table. Honey added with additives drips on paper, which will quickly spread around and then penetrate downwards, with weak penetration. This difference is obvious.
