The invention relates to the field of propolis product processing, and particularly relates to a deep processing preparation method for a propolis powder, and a product thereof. The preparation method comprises the following steps: hardening and crushing a propolis raw material to obtain a propolis raw material powder; carrying out alcohol extraction on the propolis raw material powder to obtain a thick propolis extract paste; and mixing the thick propolis extract paste with amino acid and auxiliary materials, grinding, carrying out freeze drying, and crushing to obtain the propolis powder. According to the preparation method disclosed by the invention, the mixing condition of propolis and the auxiliary materials is improved through adding the amino acid into the thick propolis extract paste, thus the propolis can be uniformly mixed with the auxiliary materials, and then the propolis can be smoothly dried to obtain the propolis powder with good powder characteristic; and meanwhile, the propolis powder prepared by the process is suitable for propolis capsules (comprising hard capsules and soft capsules), propolis tablets and the like, and is capable of remarkably improving the problem of disintegration of propolis products.
