What is nectar? How do worker bees turn nectar into honey?

　　How is honey made. To answer this question, we need to know two knowledge points, one is what is nectar, and the other is how worker bees turn nectar into honey.

　　What is nectar?

　　Nectar is a sweet liquid secreted by plant exocrine tissues, mainly composed of sugars. It is the food of bees and the raw material for brewing honey. Broadly speaking, it includes nectar secreted by nectar glands and sweet juice secreted by extrafloral nectaries (also known as extrafloral nectar by some).

　　How do worker bees turn nectar into honey?

　　Honey and nectar are essentially different. The sweet juice (i.e. nectar) collected by bees from flowers is only the raw material for brewing honey. It needs to be brewed by worker bees before it can be converted into honey. Honey brewing is mainly undertaken by the internal bees, mainly including two processes of continuous addition of invertase and evaporation of water. Generally speaking, it takes tens of hours of continuous brewing for nectar to become honey. Finally, it is stored in the upper part of the nest spleen or the empty nest room of the side spleen and sealed with wax. In this way, the whole brewing process of mature honey is completed.
