Depending on the demands of the food to be packed, an atmosphere with environments rich in CO2 and poor in CO2 will be required. They reduce the respiration process in the products, keeping their physicalchemical, organoleptic and micro biological characteristics for a longer term.esAtmósfera modificadaCorporación Universitaria LasallistaConservación de alimentosAlimentosEmpaquetadoAlimentos - EmpaquetadoArticle
