摘要:
Soybean milk, isolated soybean protein, concentrated soybean protein or the like soybean protein free from throat-catching sensation can be obtained when whole soybeans are processed by water soaking treatment in the presence of a competitive inhibitor for .beta.-glycosidase.
摘要:
Yeasts are autolyzed to produce yeast extracts by adding sodium chloride and ethanol to active yeasts so as to make their concentrations 2 to 10 % (W/V) and 1 to 9 % (V/V) of the total volume of the autolytic reaction system respectively and thereafter subjecting said yeasts to autolysis. The thus obtained yeast extracts have a good flavour and palatability.
摘要:
A process for producing 3',5'-cyclic adenylic acid in a high yield at a lower price by culturing a strain belonging to the genus selected from the group consisting of Corynebacterium, Arthrobacter and Microbacterium such as, for example, Corynebacterium murisepticum No. 7-10 (ATCC 21977), Arthrobacter 11-211 (ATCC 21978) Microbacterium No. 205-CM7 (ATCC 21979), Microbacterium No. 205-CM-XA3 (ATCC 21980), or Microbacterium No. 205-MP-197 (ATCC 21976) in a medium containing nutrient sources such as, carbon sources, nitrogen sources, inorganic salts and the like but containing no precursors and having a pH of 5-9 at a temperature of 20.degree.-40.degree. C under aerobic condition. The obtained 3',5'-cyclic adenylic acid is well-known for its participation in various biochemical reactions in vivo and for its active role as a mediator to various hormones. It has therefore always been highly evaluated biochemical reagent.
摘要:
A protein hydrolyzate having a high free amino acid content and an excellent flavor can be obtained when salt-resistant lactic acid bacteria are additionally used in the absence or presence of at most 12 percent by weight of sodium chloride based on a volume of an aqueous medium in obtaining the protein hydrolyzate from proteinaceous materials by hydrolysis with proteolytic enzymes.
摘要:
3' ,5'-Cyclic-adenylic acid or 3' ,5'-cyclic-deoxadenylic acid can be obtained in a high purity and a high yield by adding a water-soluble organic solvent such as methyl alcohol, ethyl alcohol, n-propyl alcohol, isopropyl alcohol, tert-butyl alcohol, acetone, N,N'-dimethylformamide, dioxane, tetrahydrafuran, ethyleneglycolmonomethylether and the like singly or in combination to an aqueous solution containing as impurities one or more kinds of nucleotides other than 3' ,5'-cyclicadenylic acid and 3' ,5'-cyclic-deoxyadenylic acid, nucleosides, nucleobases, colored substances, proteins and the like in addition to 3' ,5'-cyclic-adenylic acid or 3', 5'-cyclic-deoxyadenylic acid.The said 3' ,5'-cyclic-adenylic acid or 3' ,5'-cyclic-deoxyadenylic acid are useful and valuable as a biochemical reagent.
摘要:
Producing koji for fermented food products by modifying an unmodified koji-substrate composed of a vegetable protein material and a vegetable carbohydrate material, inoculating a koji mold in the resulting modified koji-substrate, and cultivating it, wherein said cultivation is carried out in the presence of 0.1 to 1.2% by weight, based on the water content of the modified koji-substrate, of acetic acid added. This process is suitable for use in the manufacture of fermented foods such as soy sauce, miso, or sake.
