Effect of Natamycin on Physical Properties of Starch Edible Films and Their Effect on Saccharomyces cerevisiae Activity

The effectiveness of using a tapioca starch-glycerol matrix containing natamycin to control Saccharomyces cerevisiae activity in a model system was studied and the effect of the formulation on physico-chemical properties was also evaluated. The presence of natamycin tended to depress firmness at bre...
