The making of honey involves many flights by each bee each of which can only hold about 40 milligrams of nectar at any one time. Thus the bee has to make many flights before it has collected enough nectar to fill a 1lb jar. The nectar is collected by sucking it up through the food canal of the probocis and then via the pharynx and oesophagus to the honey sac in the abdomen. On the way back to the hive the enzyme invertase is added to the nectar as it travels to the honey sac, this starts the conversion of the sucrose in the nectar into fructose and glucose .On reaching the hive the foraging bee gives the modified nectar to the house bees who continue the process and stack the honey into the cells. During this process water is evaporated and chemical changes of disaccaride to monosaccarides occour. In its lifetime the bee brings back enough nectar to fill a teaspoon, so dont waste any of it, it may seem a small amount to you but its a bees lifetimes work!
