Abstract:
A composition containing poly(lactic acid), at least one bacteriocin (e.g., nisin, generally in the form of Nisaplin®), and at least one plasticizer (e.g., lactic acid, lactide, triacetin, glycerol triacetate), and optionally at least one pore forming agent. A method of making the composition, involving mixing about 100% of the total of the poly(lactic acid), about 50% to about 90% of the total of the at least one plasticizer, and optionally at least one pore forming agent at a first temperature of about 150° to about 170° C. to form a mixture, cooling the mixture to a second temperature of about 115° to about 125° C., adding at least one bacteriocin and about 10% to about 50% of the total of the at least one plasticizer and the remainder of the total of the poly(lactic acid) to the mixture and mixing to form the composition.
