1, royal jelly

Bee yellow, also known as bee yellow liquid and royal jelly, is the secretion of pharyngeal glands of young worker bees who cultivate larvae in bee nests, and it is the food for the larvae who will become queen bees, and it is also the food for the queen bees for life. Yellow has a typical taste of phenol and acid. The taste is sour, astringent and slightly spicy, and the aftertaste is slightly sweet.

2. Pollen

Pollen is a microspore heap of seed plants, and mature pollen grains are its small gametes, which can produce male gametes. Pollen is produced by anthers in stamens and reaches the pistil by various methods to pollinate the ovule. China is an ancient civilization with the earliest consumption of pollen, and "pollen honey syrup" is a traditional food in ancient China.

3. honey

Honey, also known as sweetness, is a supersaturated solution of honey and sugar brewed by bees. It will crystallize at low temperature. Glucose will produce crystals, and the part that does not produce crystals is mainly fructose. Honey is a yellow-white viscous liquid made by natural fermentation of nectar collected by bees. The ancient Greeks regarded honey as a "godsend". Since the Tang, Song and Yuan Dynasties, the economy and agriculture have flourished, and the application of honey has also developed, which can be seen from a large number of records in Tang poetry and other aspects.

Introduction of bees

Bees are social insects, which are composed of queen bees, drones, worker bees and other individuals. Worker bees have the most social division of labor and the heaviest task. It can be said that except for the respective tasks of the queen bee and the drone, other work in the bee colony is undertaken by the worker bees. Worker bees are female organ hypoplasia, but many of their structures are specialized to meet the needs of work. For example, the wind bag in their foregut is specialized into a honey sac for storing nectar.

To brew 1 kg honey, worker bees need to collect 10 kg nectar. It takes a total of 320 thousand kilometers to fly back and forth, about 8 times around the earth. Worker bees begin to work as soon as they are born, and the division of labor changes with age.

Under normal circumstances, when worker bees 1~3 days old, they are responsible for keeping the eggs warm and cleaning the spawning room; At the age of 3~6 days, it is switched to feeding large larvae to regulate pollen and honey; 6~ 12 days old, secreting royal jelly and feeding larvae and queen bees; 12~ 18 years old, changed to secrete wax to make spleen and clean the hive; After 18 days old, its task is to collect nectar, water, pollen, propolis and nest door defense.
