ABSTRACT:
A process for producing a preservative having anti-oxidant and anti-bacterial action comprises steps of: preparing a starting material selected from the group consisting of herb family spices, residues obtained after the recovery of essential oils from herb family spices, oleoresins extracted from herb family spices with a polar solvent, and oleoresins extracted from herb family spices with a non-polar solvent and associated residues; subjecting the starting material to extraction with a solvent mixture of polar and non-polar solvents, the ratio by volume of the polar solvent to the non-polar solvent ranging from 2:98 to 50:50; and recovering an extractive to obtain a preservative by distilling off the solvents from said extractive.
