What % water is nectar?
80
What sugars are nectar made of?
Sucrose, fructose, glucose
What is pollen mainly comprised of?
Protein

Helps turn nectar into honey
Changes sucrose into equal parts fructose and glucose
Where do bees release invertase from?
Salivary glands
What % water is nectar when it’s deposited into the honeycomb?
20

This is what nectar is when it’s deposited in the honeycomb
Too much sugar for the water to be able to dissolve
How is invertase added?
Continually added from constant exchange of nectar to different bees

Types of plants the bees visit
What can pollen in honey lead to?
Crystallization
How many color categories of honey does the USDA have?

Type of flower visited
Exposure to heat
Storage time
What are the grades of honey?
