Aiming at the characteristics that smallanthus sonchifolius juice easily generates brown stain and is easily precipitated, the invention provides a production method of concentrated smallanthus sonchifolius normal juice and normal juice powder, and the concentrated smallanthus sonchifolius normal juice can be rapidly clarified and does not contain any color fixatives and any antioxidants. The method comprises the steps of: washing a fresh smallanthus sonchifolius raw material, removing the peels of the fresh smallanthus sonchifolius raw material and cutting the peeling smallanthus sonchifolius raw material into pieces; grinding the smallanthus sonchifolius pieces into thick liquid by hot water, and juicing; adding a natural clarifying agent to precipitate protein, heavy metal ions, pectin, tannin, pesticide residues and other impurities; filtering, separating and concentrating to obtain a brown concentrated smallanthus sonchifolius normal juice; and drying the brown concentrated smallanthus sonchifolius normal juice to obtain the brown smallanthus sonchifolius normal juice powder. The normal juice powder can be further used as a raw material of health products, or juice, juice beverages, tablets, buccal tablets, electuary, capsules, oral liquid, and the like. The chemical color fixative, the antioxidant, a suspending agent, a stabilizer and a thickening agent are not added in the whole process; the dosage of the clarifying agent is prevented from being insufficient or excessive by adjusting the dosage and the proportion of the composite clarifying agent, so that the residue of the clarifying agent in the juice can be controlled, and the normal juice flavor of the smallanthus sonchifolius can be maintained; and by using the production method, the storage time of the smallanthus sonchifolius is prolonged, the product quality and the safety are guaranteed, the transportation cost can be saved and the application range of the smallanthus sonchifolius can be expanded.
