XERRADA : APLICACIONS DELS GASOS A LA IND\u00daSTRIA ALIMENT\u00c0RIA, 18\/03\/15<\/p>\n

La xerrada va estar a c\u00e0rrec de l\u2019 empresa PRAXAIR, que \u00e9s prove\u00efdora de l\u2019 Escola tant de gasos per a \u00fas alimentari com dels gasos de laboratori.
\nDes de sempre, la conservaci\u00f3 dels aliments ha esta un factor cr\u00edtic, al voltant del qual s\u2019 hi han fet molts d\u2019 esfor\u00e7os. El canvi en l\u2019 estil de vida i d\u2019 adquisici\u00f3 dels productes alimentaris, aix\u00ed com la globalitzaci\u00f3 de la gastronomia, requereix per\u00edodes de conservaci\u00f3 dels aliments cada cop m\u00e9s llargs.
\nLa introducci\u00f3 de les atmosferes modificades a les barquetes d\u2019 envasat, ha significat un avan\u00e7 important en aquest sentit, donat que la prolongaci\u00f3 del temps de vida \u00fatil de l\u2019 aliment no requereix una distribuci\u00f3 m\u00e9s complexa ni m\u00e9s cara. L\u2019 objectiu de la substituci\u00f3 de l\u2019 aire atmosf\u00e8ric per una barreja de gasos adequada a cada producte \u00e9s conservar tant les qualitats organol\u00e8ptiques com aturar el creixement o disminuir la microbiota inicial del producte. Praxair ofereix combinacions de gasos adequats per a la conservaci\u00f3 de diferents tipus d\u2019 aliments com carns vermelles, vegetals, productes l\u00e0ctics, peixos i mariscs.
\nPraxair \u00e9s una de les empreses col\u2022laboradores del PROJECTE INNOVA del Cicle Formatiu de Grau Superior de Processos i Qualitat en la Ind\u00fastria Aliment\u00e0ria, que estudia la conservaci\u00f3 de carns vermelles crues en barquetes de diferents tipus de material pl\u00e0stic que a m\u00e9s estan plenes d\u2019 una barreja de gasos adequada per allargar la vida \u00fatil d\u2019 aquest tipus d\u2019 aliment.
\nVan parlar, a m\u00e9s, de la Criogenitzaci\u00f3 o conservaci\u00f3 per ultracongelaci\u00f3 i els usos tant a la Ind\u00fastria Aliment\u00e0ria com els usos Culinaris i els gasos implicats en aquest proc\u00e9s com s\u00f3n el Di\u00f2xid de Carboni i el Nitrogen L\u00edquid.<\/p>\n
