摘要 |
<p>A process for obtaining a film comprised of the incorporation of naturally-sourced antimicrobial agents in a polymeric structure to develop packages for increasing the shelf life of refrigerated meat, preferentially refrigerated fresh salmon, wherein said process comprises the following steps: a) obtaining microcapsules of a naturally- sourced antimicrobial agent in an enveloping medium, comprising the steps of: a1) producing an aqueous phase dissolving gum arabic (Quimatic) and Tween 20 in distilled water; a2) producing an oily phase through a solution of the naturally- sourced antimicrobial agent with a mixture of thymol and carvacrol; a3) preparing an emulsion incorporating the aqueous phase onto the oily phase; b) incorporating the microcapsules into polymers, previously treating them in order to reduce their surface tension (corona treatment), the microcapsules settling over the film, and letting them dry on a stove at controlled temperature.</p> |
