Abstract

Det beskrives en fremgangsmåte for produksjon av kimfrie, tørkede materialer, spesielt av kimfrie, tørkede nærings- og nytelsesmidler eller deres forprodukter. Her foretas først en desinfisering av det kimholdige materialet med en inertgass, idet man setter vannholdig, kimholdig material i kontakt med en inertgass, fortrinnsvis karbondioksid eller en karbondioksid-nitrogen-blanding. Under denne behandlingen kan det dreie seg om den i og for seg kjente Cell-Cracking-metoden eller om en metode for superkritisk behandling, særlig med ekstraksjon som mål. Fortrinnsvis setter man kimholdig material med innstillet vanninnhold i kontakt med inertgass som fortrinnsvis føres i kretsløp og har et vanninnhold som minst er så høyt at det tilsvarer likevektsdamptrykket i materialet som skal desinfiseres, l tilknytning til desinfiseringsbehandlingen skjer en tørking idet man setter materialet i kontakt med en inertgassblanding, fortrinnsvis karbondioksid eller en karbondioksid-nitrogen-blanding, som føres i et kretsløp og har evne til å oppta vann. Fremgangsmåten egner seg til skånsom desinfisering og tørking av næringsmidler samt også til skånsom desinfisering og tørking av allerede tørkede, men kimholdige materialer.A process is described for the production of germ-free, dried materials, especially of germ-free, dried food and pleasure products or their precursors. Here, a first disinfection of the germ-containing material is made with an inert gas, contacting aqueous germ-containing material with an inert gas, preferably carbon dioxide or a carbon dioxide-nitrogen mixture. During this treatment it may be the well-known Cell-Cracking method or a method of supercritical treatment, especially with extraction as a target. Preferably, germ-containing material with adjusted water content is contacted with inert gas, which is preferably circulated and has a water content which is at least so high that it corresponds to the equilibrium vapor pressure in the material to be disinfected. an inert gas mixture, preferably carbon dioxide or a carbon dioxide-nitrogen mixture, which is circulated in a circuit and is capable of absorbing water. The process is suitable for gentle disinfection and drying of foodstuffs as well as for gentle disinfection and drying of already dried but germ-containing materials.
