摘要:
The present invention relates to a method for sterilizing microbial cells and to sterilized microbial cells, in which microbial cells or a culture containing microbial cells is treated with a polyethylene glycol-based nonionic surfactant so that almost all of the microbial cells are sterilized while the enzyme activity expressed in the microbial cells is maintained at a high level. In detail, the present invention relates to a method for sterilizing microbial cells and a material containing the sterilized microbial cells, in which the microbial cells are sterilized using a polyethylene glycol-based nonionic surfactant that can be used for foods so that the microbial cells are sterilized to be used in food production. Further, the present invention relates to a material containing sterilized microbial cells that can be used in processes for preparing tagatose, in which Corynebacterium genus microbial cells that produce Galactose and/or Arabinose isomerase are sterilized using a polyethylene glycol-based nonionic surfactant.
摘要:
The present invention relates to a method for preparing tagatose from residue after extracting coffee, comprising: obtaining a hydrolysate by hydrolyzing residue after extracting coffee into acid; obtaining a hydrolysate refined by decolorization and ion-refining; and obtaining tagatose by isomerizing the refined hydrolysate to an arabinose isomerase.

摘要:
The present invention relates to a sweetener composition for preventing and improving obesity, containing: an ingredient for inhibiting the absorption of glucose and fructose; and a glycolysis inhibiting sugar or sugar alcohol as an active ingredient, wherein the obesity prevention and improvement effects and sweetening quality are enhanced.
摘要:
The present invention relates to a composition for preparing tagatose, wherein the composition is used for preparing tagatose from fructose and contains a protein including any one amino acid sequence of SEQ ID NOS: 1 to 7 or a microorganism expressing the protein. In addition, the present invention relates to a method for preparing tagatose from fructose, the method comprising a step of allowing the composition to react with fructose.
