Freezing the pollen will keep it fresh and at full strength for up to 2 years. You may keep the pollen in a freezer bag or you may transfer it to some other type of container. Pollen can loose its strength after an extended period of time at room temperature.
Direct sunlight can also reduce the strength of pollen.
Of course short reasonable periods at room temperature will not have any effect, but weeks or months will. Honey does contain some pollen in it, but very little. Pure natural honey is however the only food that will never spoil. Actually it is not processed at all. Pure natural unprocessed bee pollen is simply cleaned to remove obvious foreign particles such as bee wings and legs.
