Patent ID: 8168239

Claim:
A method for production of a diet food with medicinal herbs, comprising: a first step of preparing a diet herb composition comprising medicinal herbs selected from a first, a second and a third group, respectively; a second step of immersing 75 weight parts of the medicinal herb of the first group in 450 weight parts of a 50% aqueous alcohol solution at room temperature for 12˜24 hours, heating the medicinal herb in the solution at 60-75° C. for 3 hours and then at 78˜82° C. to the extent that the alcohol completely evaporates, to give a liquid extract and a solid residue, and separating the liquid extract from the solid residue; a third step of immersing 15 weight parts of the medicinal herb of the second group and 10 weight parts of the medicinal herb of the third step in 150 weight parts of a 50% aqueous alcohol solution at room temperature for 12˜24 hours and heating the medicinal herb in the solution at 60˜75° C. for 3 hours and then at 78˜82° C. to the extent that the alcohol is completely evaporated, to give a liquid extract and a solid residue; a fourth step of combining the solid residue of the second step with the liquid extract and the solid residue of the third step, heating the combination at 110˜115° C. for 60˜90 min under a high pressure to give a liquid extract and a solid residue, and separating the liquid extract from the solid residue; and a fifth step of admixing the extract of the fourth step with the extract of the second step and concentrating the admixture at room temperature under a reduced pressure to 20% of the volume thereof.
