How Do Bees Make Honey from Flower Nectar?
蜜蜂如何把花蜜变成蜂蜜？
-
Bees collect nectar from flowers using their long, tube-like tongues.
-
They store the nectar in a special stomach called the honey stomach.
-
Back at the hive, worker bees pass the nectar mouth-to-mouth to reduce its water content.
-
Enzymes added during this process break down complex sugars into simpler ones.
-
Bees fan their wings to evaporate more water until the nectar becomes thick honey.
-
Once water drops below 18%, the honey is sealed in wax cells for storage.
-
This low moisture level prevents bacteria and yeast from growing inside.
-
A single bee makes only about 1/12th of a teaspoon of honey in its lifetime.
-
Honey’s natural acidity and hydrogen peroxide also help keep it fresh for years.
-
Humans have harvested honey for over 9,000 years using sustainable methods.
