The materials produced from cranberry, blueberry, blackberry, grape or Aronia berry show significant antibacterial and antiviral properties.

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.

Selon cette invention, on prépare un concentré colorant soluble bioactif à partir du jus de canneberge et d'autres fruits ou végétaux par la précipitation de substances à partir du jus ou de l'homogénéisat avec du polyvinylpyrrolidone ou de l'alcool polyvinylique solubles. Les substances peuvent être précipitées à partir d'une multitude de matières végétales et se présentent comme un solide coloré qui se dissout facilement dans l'eau. Les substances produites à partir de canneberge, de myrtille, de mûre, de raisin ou d'aronie manifestent des propriétés antimicrobiennes et antivirales remarquables. Ces compositions se prêtent à la consommation en tant que thérapeutiques ou nutraceutiques, elles peuvent être utilisées comme colorants ou appliquées topiquement. Des tests effectués avec du sang humain frais ont montré que les substances solubles à base de canneberge peuvent détruire des virus et des bactéries sans véritablement causer de dommage aux fractions sanguines, ce qui en fait des agents antimicrobiens injectables potentiels.
