摘要:
A low common salt soy sauce, which has good flavor, significantly suppresses elevation of blood pressure, prevents cardiac hypertrophy, and is also available as special nutritious food, is obtained. 1.0% to 10.0% by weight of potassium chloride and 0.1% to 5.0% by weight of γ-aminobutyric acid are added to a reduced common salt soy sauce, so as to obtain a low common salt soy sauce of issue. Otherwise, a KCl-containing low common salt soy sauce is obtained by: (1) a common production method of soy sauce, in which a mixed solution consisting of KCl and common salt is used as mother water; (2) a method of subjecting a soy sauce obtained using saline solution as mother water to electrodialysis, a membrane treatment, or the like, so as to eliminate common salt from the above soy sauce, and then adding KCl thereto; or other methods. Thereafter, γ-aminobutyric acid is added to the above KCl-containing low common salt soy sauce, so as to obtain a low common salt soy sauce comprising 0% to 10% by weight of common salt, 1.0% to 10.0% by weight of potassium chloride, and 0.1% to 5.0% by weight of γ-aminobutyric acid.

摘要:
A cyclic oligosaccharide or salts thereof comprising glucoses bound cyclically via .alpha.-1,6-linkages and having at least one S-oxo acid group bound, and ana gent for preventing or treating retroviral diseases which comprises said cyclic oligosaccharide or salts thereof as an active ingredient. The novel sulfated cyclic isomaltoligosaccharide inhibits infection of host cells with various retroviruses such as AIDS virus etc. so effectively that it has a significant preventive and therapeutic effect on diseases caused by retroviruses. Accordingly, said oligosaccharide can be utilized as an agent for preventing or treating retroviral diseases in pharmaceutical industry.
