This subclass encompasses manufacturing processes such as pasteurization, homogenization, fermentation, and separation techniques; formulation of specialty dairy products; and technologies for extending shelf life and improving product quality. The classification includes both conventional dairy processing and emerging alternatives like milk replacers and cheese analogues derived from plant or synthetic sources.
