A particle structure includes a particle and a low-temperature film coating, the particle contains active ingredients, the low-temperature film coating is coated on the outer surface of the particle with a temperature lower than 40 u2103, so that the active ingredients of the particle are not damaged by heat, and the particle is isolated from the outside to extend the storage period, thereby forming a particle structure with better assurance of the particle's activity and absorption effect.一種顆粒結構,包括有一顆粒及一低溫膜衣,該顆粒含有活性成分,該低溫膜衣係以溫度低於40℃包覆於該顆粒外表面,使該顆粒之活性成分免於熱破壞,並將該顆粒與外界隔離延展保存期限,藉此構成一具有較佳確保顆粒之活性與吸收效用之顆粒結構。
