Abstract (en)

[origin: WO2018115582A1] The invention relates to process for converting plant material to plant extract having antimicrobial activity, said process comprising the steps, where in the first step at least one plant material is ground in the presence of a first medium or without a medium, to obtain particles having average particle size from 10 to 1000 µm, and in the second step the particles are mixed with a second medium to obtain a mixture comprising bioactive compounds, and the mixture is subjected to separation whereby a plant extract is separated from a plant residue.
