Description
'7404642-6 svampar, med etylenoxid, metylformiat eller en blandning av dessa gaser, varvid efter behandlingen inga ytterligare omsättningsprodukter bildas, så mögelsvamparna själva avdödas. I Med mycket gott resultat användes en gasblandning av 40-60 volymprocent metylformiat och 40-60 volymprocent etylenoxid. Fungi, with ethylene oxide, methyl formate or a mixture of these gases, whereby after the treatment no further reaction products are formed, so that the molds themselves are killed. With very good results, a gas mixture of 40-60% by volume of methyl formate and 40-60% by volume of ethylene oxide was used.
För att minska faran för antändning är det i många fall lämpligt att för behandlingen använda en gasblandning, som förutom etylenoxid och/eller metylformiat innehåller en inert gas, såsom kväve eller koldioxid.In order to reduce the risk of ignition, it is in many cases suitable to use for the treatment a gas mixture which, in addition to ethylene oxide and / or methyl formate, contains an inert gas, such as nitrogen or carbon dioxide.
Av säkerhetsskäl är det lämpligt att genomföra behandlingen under reducerat tryck. Vid användning av dessa åtgärder förhindras att behandlingsgasen strömmar ut om behandlingsbehållaren eller behandlingsrummet blir otäta.For safety reasons, it is advisable to carry out the treatment under reduced pressure. When using these measures, the treatment gas is prevented from flowing out if the treatment container or treatment room becomes leaky.
Exempel l.Example 1
Jordnötsexpellermassa, som genom angrepp av en stam av Asper- gillus flavus per gram innehöll 12 pg aflatoxin Bl, infördes i en begasningskammare med en volym av ll liter. Kammaren evakuerades till ett resttryck av 40 torr. Det flytande behandlingsmedlet förgasades i en värmeväxlare och infördes i begasningskammaren. Efter begas- ningstiden avsögs behandlingsmedlet med hjälp av en vakuumpump och steril friskluft infördes genom ett bomullsfilter i begasningskamma- ren till tryckutjämning.Peanut expeller pulp, which by attack of one strain of Aspergillus flavus per gram contained 12 pg of aflatoxin B1, was introduced into a gasification chamber with a volume of 11 liters. The chamber was evacuated to a residual pressure of 40 torr. The liquid treatment agent was gasified in a heat exchanger and introduced into the gasification chamber. After the gassing time, the treatment agent was aspirated by means of a vacuum pump and sterile fresh air was introduced through a cotton filter into the gassing chamber for pressure equalization.
För behandlingen användes följande gaser: A etylenoxid B metylformiat C en blandning av 50 volymprocent etylenoxid och 50 volumprocent metylformiat.The following gases were used for the treatment: A ethylene oxide B methyl formate C a mixture of 50% by volume of ethylene oxide and 50% by volume of methyl formate.
