Description
Oppfinnelsen vedrører en fremgangsmåte til uskadeliggjøring av de giftige stoffvekselprodukter*av muggsopp "i stoffer eller stoffblandinger ved behandling av disse stoffer eller stoffblandinger med etylenoksyd og/eller metylformiat. The invention relates to a method for neutralizing the toxic metabolic products* of molds in substances or substance mixtures by treating these substances or substance mixtures with ethylene oxide and/or methyl formate.
En slik fremgangsmåte er omtalt i Inaugural-Dissertation av Gero Mayr av 12. juni 1973 "Untersuchung iiber die Wirkung von Atylenoxid zur Beseitigung von Schimmelpilzen und deren Stoffwechselprodukten". Ifølge denne publikasjon uskadeliggjøres de giftige stoffskifteprodukter av muggsopp i jordnøtt eller i jordnøtt-expellere, mycotoksinene, spesielt aflatoxinene, ved behandling med etylenoksyd og/eller metylformiat, dvs. gjøres'ugiftig for nytelse av dyr eller mennesker. Det er ikke klart ved hvilke kjemiske omsetninger denne uskadeliggjøring oppnås. Such a method is described in the Inaugural Dissertation by Gero Mayr of 12 June 1973 "Untersuchung iiber die Wirkung von Atylenoxid zur Beseitigung von Schimmelpilzen und deren Stoffwechselprodukten". According to this publication, the toxic metabolic products of molds in peanuts or in peanut expellers, the mycotoxins, especially the aflatoxins, are neutralized by treatment with ethylene oxide and/or methyl formate, i.e. rendered non-toxic for animal or human consumption. It is not clear by which chemical reactions this neutralization is achieved.
Oppfinnelsens oppgave er en videreutforming av denne fremgangsmåte ifølge hvilken det oppnås en videregående uskadeliggjøring av mycotoksiner. The task of the invention is a further development of this method according to which an advanced neutralization of mycotoxins is achieved.
Denne oppgave løses ved at behandlingen gjennom-føres ved et fuktighetsinnhold av stoffene eller stoffblandingene på minst ca. 10 %. Dette fuktighetsinnhold kan oppnås ved enkel tilsetning av vann eller sprøyting med vann. Under disse grenser uskadeliggjøres bare mindre mengder av mycotoksiner . This task is solved by the treatment being carried out at a moisture content of the substances or substance mixtures of at least approx. 10%. This moisture content can be achieved by simply adding water or spraying with water. Below these limits, only smaller amounts of mycotoxins are neutralized.
Fortrinnsvis holdes fuktighétsinnholdet av stoffene eller stoffblandingene som skal behandles ved maksimalt ca. 16 %. Over denne grense gjøres mycotoksiner riktignok også meget uskadelig, det kan imidlertid danne seg formerte omdan-nelsesprodukter av de til behandling anvendte gasser som etylen-glykol eller etylenklorhydrin som er sunnhetsskadelige. Preferably, the moisture content of the substances or substance mixtures to be treated is kept at a maximum of approx. 16%. Above this limit, mycotoxins are admittedly also very harmless, however, increased transformation products of the gases used for treatment such as ethylene glycol or ethylene chlorohydrin can form which are harmful to health.
Det ble funnet at ved de angitte innhold av fuktig-het oppnås de beste resultater når det til behandlingen anvendes en gassblanding som inneholder ca. 4 0 - 60 volum-% etylenoksyd og ca. 60-40 volum-% metylformiat. It was found that at the specified moisture content, the best results are achieved when a gas mixture containing approx. 4 0 - 60 volume-% ethylene oxide and approx. 60-40% by volume methyl formate.
I mange tilfeller er dét hensiktsmessig til behandling å anvende en med en inert gass som nitrogen eller karbon-dioksyd fortynnet gassblanding. In many cases, it is appropriate for treatment to use a gas mixture diluted with an inert gas such as nitrogen or carbon dioxide.
Fremgangsmåten ifølge oppfinnelsen kan gjennom-føres således at . stoffer eller stoffblandinger som skal behandles og som er bragt til eller inneholder den ønskede fuktighetsinnhold innbringes i en lukket beholder, at denne beholder deretter evakueres og deretter innføres den til 'behandling anvendte gass eller gassblanding i den evakuerte beholder. The method according to the invention can be carried out so that . substances or mixtures of substances to be treated and which have been brought to or contain the desired moisture content are introduced into a closed container, that this container is then evacuated and then the gas or gas mixture used for treatment is introduced into the evacuated container.
Fortrinnsvis anvender man gassen eller gassblandin-gen i konsentrasjoner på 1000 til 1500 mg/liter. The gas or gas mixture is preferably used in concentrations of 1000 to 1500 mg/litre.
Behandlingsvarigheten er avhengig av typen og volumvekten av stoff eller stoffblandingen som skal behandles. Fortrinnsvis behandler man i 6-16 timer. The treatment duration depends on the type and volume weight of the substance or substance mixture to be treated. Preferably, you treat for 6-16 hours.
Nedenstående tabell viser at ved behandling av muggede jordnøtter som inneholder Aflatoxin B^avtar ved 16 timers gassbehandling med en blanding av 50 volum-% etylenoksyd og 50 volum-% metylformiat i en konsentrasjon på 1500 mg/liter gassbehandlingsrom,.innholdet av Aflatoxin vesentlig sterkere når materialet har et fuktighetsinnhold på mer enn 10 %. Denne nedgang i Aflatoxin-innholdet er i alle tilfelle å fastslå uavhengig av den opprinnelig tilstedeværende mengde Aflatoxin. The table below shows that when moldy peanuts containing Aflatoxin B are treated with a 16-hour gas treatment with a mixture of 50% by volume ethylene oxide and 50% by volume methyl formate in a concentration of 1500 mg/litre in the gas treatment room, the content of Aflatoxin decreases significantly more when the material has a moisture content of more than 10%. This decrease in the Aflatoxin content can in all cases be determined independently of the amount of Aflatoxin originally present.
