year old , by the standard grading of korea ginseng public enterprise , ginseng was selected as a sample . the comparative example was prepared by removing fine roots of the selected ginseng , followed by processing under ultra - high pressure ( 600 to 800 mpa ) at the elevated temperature of 60 ˜ 80 ° c . for 5 to 30 minutes . the processed ginseng is then cooled to room temperature and is dried by which 12 ˜ 13 % moisture remains . meanwhile , the control group was prepared by removing fine roots of the selected 6 - year old ginseng , followed by cleansing and steaming at 90 ˜ 110 ° c . temperature for 1 hour . it was then kept at the same temperature for 6 hours , and then steaming process was stopped . the steamed ginseng was cooled to room temperature , and was dehydrated to produce dehydrated red ginseng ( 12 ˜ 13 % moisture ). each sample was compared in their function , visible color , and tissue condition by the panel test . the results are summarized in table 1 below . we find the method for preparing comparative example , which was processed by the ultra - high pressure , superior in its quality than the method for preparing steamed control group . according to example 1 , the comparative example was prepared by processing a 4 - year old ginseng under ultra - high pressure , while the control group was prepared by steaming a 6 - year old ginseng . each sample was analyzed in their total crude saponin and various ginsenoside contents . the results are summarized in table 2 below . even though the 4 - year old ginseng was used for the comparative example , the total amount of crude saponin was similar to that of the 6 - year old control group ginseng . moreover , the comparative example contained unique ginsenoside found in red ginseng . according to example 1 , the comparative example was prepared by processing a 6 - year old ginseng under ultra - high pressure , meanwhile the control group was prepared by steaming a 6 - year old ginseng . each sample was analyzed in their total crude saponin and various ginsenoside contents . the results are summarized in table 3 below . comparing the total amount of crude saponin , the comparative example showed more than twice as much as the control group . furthermore , each amount of ginsenoside contained in the comparative example showed more amount in all contents except for − rg3 and rd . as mentioned in the said example , the method used in preparing the comparative example is superior in its function and saponin content to that of the control group . a 6 - year old ginseng was selected as a sample . the fine roots of the selected ginseng were removed , followed by processing under ultra - high pressure ( 600 to 800 mpa ) at the elevated temperature of 60 ˜ 80 ° c . for each 30 and 60 minutes . the separately processed ginsengs are then cooled to room temperature and dried . analysis was done on total saponin content and ginsenoside content on each product . the results are summarized in table 4 below . as mentioned in the said example , the 30 minute processing group contained more amount of crude saponin and each ginsenoside content than that of 60 minute processing group . a 6 - year old ginseng was selected as a sample . the fine roots of the selected ginseng were removed , followed by processing under ultra - high pressure ( 600 to 800 mpa ) at the elevated temperature of 60 ˜ 80 ° c . for 30 minutes . at this time , the comparative example was prepared under ultra - high pressure without vacuum packaging , while the control group was prepared under ultra - high pressure with individual vacuum packaging . when comparison was made on their physical appearance and functions , both total amount of saponin and each ginsenoside contents showed superior results on the vacuum packaged processing . the results are summarized in table 5 below . a 6 - year old ginseng was selected as a sample . the fine roots of the selected ginseng were removed , followed by processing under ultra - high pressure ( 600 to 800 mpa ) at the elevated temperature of 60 ˜ 80 ° c . for 5 ˜ 60 minutes . at this time , water that fills in the said processing apparatus was treated with citric acid to lower the ph at 6 , 4 , and 2 before processing ginseng under ultra - high pressure . comparing the unique ginsenoside rg content , more amount results with lower ph accordingly . 6 - year old ginseng was selected as a sample . the fine roots of the selected ginseng were removed , followed by processing under ultra - high pressure ( 600 to 800 mpa ) at the elevated temperature of 60 ˜ 80 ° c . for 30 minutes . at this time , the comparative example was prepared under ultra - high pressure after vacuum packaging , while the control group was prepared further comprising the step of steaming fresh ginseng before vacuum packaging . when comparison was made on their physical appearance and functions , the control group showed more amount in total saponin content , and each amount of ginsenoside contained in the control group showed more amount in contents except for re , rf , rg1 . the results are summarized in table 7 below . the present invention uses ultra - high pressure comprising the said components to enhance active ingredient about twice that of prior method for processing ginseng .
the present invention relates to a method for increasing active ingredient of ginseng by ultra - high pressure . more precisely the invention relates to a method for increasing high active ingredients like ginsenosides comprising treating ginseng with ultra - high pressure .
