There are several artificial pollen diets available for honeybees that incorporate a variety of ingredients like soy, corn gluten, yeast, egg, or milk protein, but they often fail to provide the essential macronutrients (such as lipids and proteins), micronutrients (vitamins and minerals), and antioxidants needed by honeybees to thrive. The Food and Drug Administration has warned against the use of some bee pollen products because they are adulterated with unapproved drugs including sibutramine and phenolphthalein. Bee pollen is not safe for pregnant women and should not be used during breastfeeding. Bee pollen is safe for short term use, but for those with pollen allergies, allergic reactions may occur (shortness of breath, hives, swelling, and anaphylaxis). Potential risks of consuming bee pollen include contamination by fungal mycotoxins, pesticides, or toxic metals. Bee bread is rich in micronutrients, minerals, and phenolic compounds. Use as a health supplement īee pollen has been touted by herbalists as a treatment for a variety of medical conditions. Despite this microbial diversity, stored pollen is a preservation environment similar to honey, and contains consistently low microbial biomass. A study of bee pollen samples showed that they may contain 188 kinds of fungi and 29 kinds of bacteria. Bee bread is a niche for yeasts and bacteria, including lactic acid bacteria, Bifidobacterium, Bacillus spp., and others. Accordingly, chemical and nutritional analyses of bee pollen apply only to the specific samples being tested and cannot be extrapolated to samples gathered in other places or other times.Īlthough there is no specific chemical composition, the average composition is said to be 40–60% simple sugars (fructose and glucose), 20–60% proteins, 3% minerals and vitamins, 1–32% fatty acids, and 5% diverse other components. Like honey and propolis, other well-known honeybee products that are gathered rather than secreted (i.e., in contrast to royal jelly and beeswax), the exact chemical composition depends on the plants from which the worker bees gather the pollen, and can vary from hour to hour, day to day, week to week, colony to colony, even in the same apiary, with no two samples of bee pollen being exactly identical. This method of pollen usage can also be seen in the wood-nesting bee species Xylocopa sulcatipes and Xylocopa sonorina. The egg hatches and the larva consumes the pollen directly the pollen is not stored separately from the brood. With the leafcutter bee, as in most such bees, when the pollen ball is complete, the female lays an egg on top of the pollen ball, and seals the brood cell. īees other than Apis typically form pollen into balls these are primarily ground-nesting bees or twig-nesting bees, most of which are solitary, such as leafcutter bees. Bee pollen is the primary source of protein for the hive. During collection and possibly packing, the pollen is mixed with nectar and bee salivary secretions, signalling the start of the lactic fermentation process. The foragers unload the pollen they gather directly into open cells located at the interface between the brood and stored honey, creating a typical band of what is called bee bread – the substance which is the main food source for honeybee larvae and workers.įoraging bees bring pollen back to the hive, where they pass it off to other worker bees, who pack the pollen into cells with their heads. įorager bees that gather pollen do not eat it themselves, since they stop producing the proteolytic enzymes necessary to digest it when they transition to foraging. It differs from field-gathered pollen as honeybee secretions induce a fermentation process, where biochemical transformations break down the walls of flower pollen grains and render the nutrients more readily available. In honeybees ( Apis species) pollen is stored in the chambers of the hives. Details Vertical dissection of cells from a comb, showing the packing of different types of pollen over time Bee pollen is harvested as food for humans and marketed as having various, but yet unproven, health benefits. Bee pollen is stored in brood cells, mixed with saliva, and sealed with a drop of honey. It consists of simple sugars, protein, minerals and vitamins, fatty acids, and a small percentage of other components.
