Clinical patients are prone to be suffering from malnutrition, and malnutrition is one of the important factors that causes clinical treatment complications and delay in recovery. Therefore, clinical nutrition support with special medical use formula as an important component plays a key role in the clinical treatment process. Compared with ordinary foods, formulas for special medical uses have more stringent requirements on the stability of formulation composition and the uniformity of composition mixing, so the production process is complicated. The research status of the existing production process of different dosage forms for special medical use formulas was analyzed. The effects of dispersed phase particle size and specific surface area on the stability of complex liquid dosage forms for special medical use formulas were described. Meanwhile, the prospects of applications of membrane emulsification, ultra-high pressure homogenization, spraying drying, and freeze-drying technology in the production process of special medical formula foods were proposed.
