Why does propolis powder tend to caking?
Firstly, propolis itself characteristic, it is very sticky,
The higher the propolis content, the stickier it is
Secondly, it have to package in well sealed in drum
Finally, temperature include storage temperature and transporation temperature, in china it is very hot from June to August, it is not good to delivery goods by air, so we will avoid this three month normally, also, propolis powder have to be storage under 18 degree.
We processing and exporting propolis powder and other bee products for 33 year, and i did international business for 13 years, we knew how to avoid above question.
