  • Oil-in-water type emulsion food
    Patent number: 6835407
    Abstract: There is provided an oil-in-water type emulsion food comprising a gelatin, in which the gelatin contains 13% by weight or less of a gelatin fraction having a molecular weight of 20,000 or less. The emulsion food exhibits a marked improvement in cold resistance such as refrigeration resistance, freeze resistance or the like. A fish gelatin is preferred as this gelatin.
    Type: Grant

  • DNA molecule encoding new aminopeptidase, and method of producing the aminopeptidase
    Patent number: 6303359
    Abstract: Disclosed are cDNA encoding a new aminopeptidase derived from germinated soybeans, a recombinant expression vector containing the DNA, a transformant obtained by the transformation with the expression vector, and a method of producing an aminopeptidase by culturing the transformed product. According to the present invention, a cDNA can be obtained encoding the amino acid sequence of aminopeptidase GX suitable for producing a highly hydrolized product from a starting material containing a protein and peptide having a high acidic amino acid content. Using the cDNA, a recombinant aminopeptidase can be mass-produced with E. coli or the like. By using the cDNA, it is also possible to produce aminopeptidase GX by using a host other than E. coli. In addition, hydrohized products having high glutamic acid content and aspartic acid content and also excellent seasoning properties can be obtained from soybean protein by combining GX thus produced with protease D3 and leucine aminopeptidase DLAP.

  • Aminopeptidase GX, and a method of hydrolyzing a protein with the same
    Patent number: 5824534
    Abstract: An aminopeptidase is provided which efficiently decomposes a low-molecular-weight peptide containing glutamic acid or aspartic acid in its sequence. A method of hydrolyzing a peptide or protein by use of the aminopeptidase is also provided. Aminopeptidase GX is derived from germinated soybean cotyledons and releases glutamic acid or aspartic acid from a peptide or protein containing glutamic acid or aspartic acid at the N-terminal end and is used to hydrolyse peptides or proteins.
