A soluble bioactive coloring concentrate can be prepared from the juice of cranberry and other fruits or vegetables by precipitatiing the material from juice or homogenate with soluble polyvinylpyrrolidone or soluble poly vinyl alcohol. The active materials which can be precipitated from a variety of plant materials and is a colored solid that is freely water-soluble. The materials produced from cranberry, blueberry, blackberry, grape or Aronia berry show significant antibacterial and antiviral properties. These compositions can be readily consumed as a therapeutic or nutraceutical, used as a coloring agent or it can be used topically. Tests on fresh human blood indicate that the soluble cranberry material can destroy bacteria and virus without appreciably damaging the blood constituents making them candidates as injectable antimicrobials. |
