Antimicrobial Composition

Abstract

The present invention describes a process to preserve a water-containing product such as a foodstuff, which comprises adding natamycin and nisin to the product, whereby at least 90% (w/v) of natamycin is dissolved and/or less than 10% (w/v) of natamycin is present in crystal form.

1 . A process to preserve a water-containing product such as a food product, which comprises applying in the product an anti-microbial composition including natamycin and nisin, whereby at least 90% (w/v) of natamycin is dissolved and/or less than 10% (w/v) of natamycin is present in solid form. 
     
     
         2 . The process according to  claim 1 , whereby natamycin is present in the product in an amount of 1 to 20 ppm natamycin based on the water content of the product. 
     
     
         3 . The process according to  claim 1 , whereby an amount of 0.25 to 20 ppm of nisin is present in the product. 
     
     
         4 . A process to preserve a product such as a food product, which comprises applying on the product an anti-microbial composition including natamycin and nisin, and said composition comprises between 0.01 and 10 ppm natamycin. 
     
     
         5 . The process according to  claim 4 , whereby nisin is present in an amount ranged between 0.0001 and 1 ppm. 
     
     
         6 . The process according to  claim 1 , whereby nisin and natamycin are added at the same time. 
     
     
         7 . The process according to  claim 1 , whereby natamycin and nisin are applied at the surface of the product. 
     
     
         8 . The process according to  claim 7 , whereby the anti-microbial composition is applied by spraying or dipping. 
     
     
         9 . A water-containing product such as a food product comprising an anti-microbial composition including natamycin and nisin, whereby at least 90% (w/v) of natamycin is dissolved and/or less than 10% (w/v) of natamycin is present in solid form. 
     
     
         10 . The product according to  claim 9 , whereby natamycin is present in an amount of 1 to 20 ppm based on the water content of the product. 
     
     
         11 . The product according to  claim 10 , whereby said product comprises 0.25 to 20 ppm of nisin. 
     
     
         12 . A product such as a food product comprising an anti-microbial composition including natamycin and nisin, whereby natamycin and nisin are present at the surface of the product. 
     
     
         13 . The product according to  claim 12 , whereby natamycin is present in an amount ranged between 0.01 and 10 ppm. 
     
     
         14 . The product of  claim 12 , whereby nisin is present in an amount ranged between 0.0001 and 1 ppm. 
     
     
         15 . Use of natamycin to obtain a product, such as a food product comprising an anti-microbial composition including natamycin and nisin, whereby at least 90% (w/v) of natamycin is dissolved and/or less than 10% (w/v) of natamycin is present in solid form.
