I am trying to follow some formulas for patties to feed my bees. Some of these patties will contain essential oils to control mites. All the formulas I have found on the internet call for brewers yeast and/or expeller-processed soybean flower. I have attempted to look up the deffinition of this but can't find it anywhere. I called the producer of a organically produced soy flower but the person I spoke with could not tell me if their soy flower was "expeller-processed". Does anyone here know what the deffinition is? Can I feed this organically produced soy flower to my bees without negative consequences??? :?
