Dissolve the gelatin in distilled water,

glycerol, the active compound in different concentrations and Tween 80 will be added. The solution will shake for 10 minutes

In Petri dishes, 50 g of the solution will be placed and dried in an oven at 30 ° C for 24 h. After 24 hours, the films will be eliminated and characterized

transmittance will be observed, between 200 and 700 nm.

moisture is calculated at 105

Antimicrobial activity determined by the method of sensitivity of the disc against different
