Lactobacillus plantarum KCCM 11322 cirsimaritin Production method of cirsimaritin fortified thistle concentrate using Lactobacillus plantarum KCCM 11322 strain

摘要

The present invention relates to a method for preparing a cirsimaritin-enriched Cirsium japonicum concentrate using a Lactobacillus plantarum KCCM 11322 strain, and more specifically, to a method for preparing a cirsimaritin-enriched Cirsium japonicum concentrate using a Lactobacillus plantarum KCCM 11322 strain, which comprises the following steps: adding purified water to dried Cirsium japonicum and subjecting the Cirsium japonicum to hot water extraction to prepare a Cirsium japonicum extraction liquid; sterilizing and cooling the Cirsium japonicum extraction liquid; adding oligosaccharide to the cooled Cirsium japonicum extraction liquid; inoculating Cirsium japonicum extraction liquid with the Lactobacillus plantarum KCCM 11322; fermenting the Cirsium japonicum extraction liquid inoculated with the strain to prepare a Cirsium japonicum fermentation broth; filtering the Cirsium japonicum fermentation broth and concentrating the Cirsium japonicum fermentation broth under reduced pressure with a concentrator to prepare the Cirsium japonicum concentrate; and mixing crystal fructose and malic acid with the Cirsium japonicum concentrate.
