Description
Fremgangsmåte til uskadeliggjøring Procedure for neutralization
av giftige stoffvekselprodukter fra of toxic metabolic products from
muggsopp. mold.
Tallrike muggsopper som eksempelvis muggsopp av slekten Aspergillus og Penicillium utvikler meget giftige stoffvekselprodukter, som betegnes .som mykotoksiner. Disse mykotdksiner, hvorav de forskjellige aflatoksiner er de mest kjente,.virker meget giftig overfor varmblodsdyr som fugler og pattedyr. Numerous molds, such as molds of the genera Aspergillus and Penicillium, develop highly toxic metabolic products, which are referred to as mycotoxins. These mycotoxins, of which the various aflatoxins are the best known, are highly toxic to warm-blooded animals such as birds and mammals.
Det er kjent å anvende etylenoksyd, metylformiat eller en blanding av begge gasser til utrydning av muggsopp. Det var imidlertid ikke kjent om hvorledes disse gasser eller gassblandinger innvirker på mykotoksinen. It is known to use ethylene oxide, methyl formate or a mixture of both gases to eradicate mould. However, it was not known how these gases or gas mixtures affect the mycotoxin.
Oppfinnelsens oppgave er en fremgangsmåte til uskadelig-gjøring av disse giftige stoffskifteprodukter. En ytterligere oppgave med oppfinnelsen er å' tilveiebringe en slik fremgangsmåte, hvor- ved også selve muggsoppen utryddes, således at etter behandlingen ifølge oppfinnelsen kan det ikke mere oppstå ytterligere giftige stoffskifteprodukter. The task of the invention is a method for rendering these toxic metabolic products harmless. A further task of the invention is to provide such a method, whereby the mold itself is also eradicated, so that after the treatment according to the invention no further toxic metabolic products can arise.
Denne oppgave løses, ifølge oppfinnelsen ved at man behandler gjenstander, stoffer eller stoffblandingers om inneholder de giftige stoffskifteprodukter av muggsopp med etylenoksyd, med metylformiat eller med blandinger av begge gasser. This task is solved, according to the invention, by treating objects, substances or substance mixtures containing the toxic metabolic products of molds with ethylene oxide, with methyl formate or with mixtures of both gases.
Med meget godt resultat anvendes en gassblanding av A gas mixture of is used with very good results
40 til 60 volum- metylformiat og 40 til 60 volum- etylenoksyd. 40 to 60 volumes of methyl formate and 40 to 60 volumes of ethylene oxide.
Por å nedsette brannfaren er det i mange tilfeller an-bragt til behandlingen å anvende en gassblanding som foruten etylenoksyd og/eller metylformiat inneholder en inert gass, som nitrogen eller karbondioksyd. In order to reduce the risk of fire, in many cases it is appropriate for the treatment to use a gas mixture which, in addition to ethylene oxide and/or methyl formate, contains an inert gas, such as nitrogen or carbon dioxide.
Av sikkerhetsgrunner er det hensiktsmessig å utføre behandlingen under nedsatt trykk.. Ved anvendelse av denne forholds-regel hindres at ved utettheter av behandlingsbeholdere eller behand-lingsrom trer behandlingsgassene utad. For safety reasons, it is appropriate to carry out the treatment under reduced pressure. By applying this precaution, it is prevented that the treatment gases escape in the event of leaks in treatment containers or treatment rooms.
Eksempel' 1. Example' 1.
Jordnøtt-"expeller" som ved angrep med en stamme av Aspergillus flavus pr. g inneholdt 12^ug Aflatoxin B-^ble bragt i Peanut "expeller" which in case of attack with a strain of Aspergillus flavus per g contained 12 µg Aflatoxin B-^ was brought in
et begasningskammer med et innhold av 11 liter. Kamrene ble evakuert til et resttrykk på 40 torr. Det flytende behandlingsmidlet ble forgasset i en varmeutveksler og ført inn i begasningskammeret. a gasification chamber with a content of 11 litres. The chambers were evacuated to a residual pressure of 40 torr. The liquid treatment agent was gasified in a heat exchanger and introduced into the gasification chamber.
Etter avløp av begasningstiden hver gang ble behandlingsmidlet frasugd ved hjelp av en vakuumpumpe og steril friskluft ble innført gjennom et vattfilter i begasningskammeret til trykkutligning. After the gassing time had expired each time, the treatment agent was sucked off using a vacuum pump and sterile fresh air was introduced through a cotton filter into the gassing chamber for pressure equalization.
Til behandling ble det anvendt følgende gasser: The following gases were used for treatment:
A Etylenoksyd A Ethylene oxide
B Metylformiat B Methyl formate
C en blanding av 50 volum- etylenoksyd og C a mixture of 50 volumes of ethylene oxide and
50 volum- metylformiat. 50 volumes of methyl formate.
Forsøksresultatene er oppstillet i følgende tabell: The test results are listed in the following table:
Påvisningen av den kvantitative bestemmelse av Aflatoxin ble gjennomført etter fremgangsmåten av Hanssen og Hagedorn (ZUL l4l (1969) 3, 129-145). The detection of the quantitative determination of Aflatoxin was carried out according to the method of Hanssen and Hagedorn (ZUL 141 (1969) 3, 129-145).
Eksempel 2. Example 2.
Jordnøtter med et sterkt angrep av en stamme av Aspergillus flavus ble behandlet med fremgangsmåten ifølge eksempel 1. Resultatene er oppstillet i følgende tabell: Peanuts with a strong attack of a strain of Aspergillus flavus were treated with the method according to example 1. The results are listed in the following table:
