Bees cannot digest pollen, they can digest bee bread which is like the difference between milk and fermented milk (like keifer or yogurt). Bee bread is a fermented product that requires pollen, several kinds of bacteria, several kinds of yeasts and a two stage fermentation process.
How do you recommend to preserve summer pollen for early spring feeding? (in addition to the amount the bees preserve)
I was thinking about putting pollen loaded combs into the super, feeding sugar syrup so the bees fill syrup on top of the pollen and cap it with wax. This way the frame could be preserved till next spring in a store.
Another way could be pushing freshly trapped pollen grain in a jar. In the anaerob environment it would ferment. The pollen grain probably has enough sugar and yeast for this.
Apart from being profitable and labor requirement, could it work?
