Keksintö kohdistuu menetelmään aineissa tai aine-seoksissa olevien homesienten myrkyllisten aineenvaihdunta-tuotteiden tekemiseksi vaarattomiksi käsittelemällä näitä aineita tai aineseoksia etyleenioksidilla ja/tai metyylifor-miaatilla.The invention relates to a process for rendering the toxic metabolites of molds in substances or mixtures of substances harmless by treating these substances or mixtures of substances with ethylene oxide and / or methyl formate.
Tämän tapaisen menetelmän on esittänyt Gero Mayr julkaisussa Inaugural Dissertation 12. kesäkuuta 1973 nimellä "Untersuchung uber die Wirkung von Äthylenoxid zur Beseitigung von Schimmelpilzen und deren Stoffwechselprodukten" ("Tutkimus etyleenioksidin vaikutuksesta homesienten ja niiden aineenvaihduntatuotteiden poistamiseksi"). Tämän julkaisun mukaan tehdään maapähkinöissä tai maapähkinäjätteissä olevat homesienten myrkylliset aineenvaihduntatuotteet, kuten mykotoksiini ja erikoisesti aflatoksiini, vaarattomiksi käsittelemällä, etyleenioksidilla ja/tai metyyliformiaatilla, so. myrkyttömiksi niin, että ihmiset ja eläimet voivat nauttia niitä. Vielä ei ole selvitetty, minkälaisten kemiallisten reaktioiden avulla tämä vaarattomaksi tekeminen tapahtuu.A method similar to that described by Gero Mayr in his Inaugural Dissertation of 12 June 1973, entitled "Study of the action of ethylene oxide on the treatment of fungi and their metabolites" ("Study of the effect of ethylene oxide on the removal of molds and their metabolites"). According to this publication, toxic fungal metabolites of peanuts or peanut waste, such as mycotoxin and in particular aflatoxin, are rendered harmless by treatment with ethylene oxide and / or methyl formate, i.e. non-toxic so that humans and animals can enjoy them. It has not yet been elucidated what kind of chemical reactions make this decontamination possible.

Keksinnön tehtävänä on tämän menetelmän kehittäminen, jolloin mykotoksiini voidaan tehdä vieläkin vaarattomammaksi .The object of the invention is to develop this method, in which case mycotoxin can be made even safer.
Keksinnön mukaiselle menetelmälle on tunnusomaista, että käsittely suoritetaan aineiden tai aineseosten kosteuspitoisuuden ollessa noin 10-16 prosenttia. Tämä kosteuspitoisuus voidaan saavuttaa yksinkertaisesti lisäämällä tai ruiskuttamalla vettä. Tämän rajan alapuolella tulee vain vähäinen määrä mykotoksiinia vaarattomaksi.The process according to the invention is characterized in that the treatment is carried out at a moisture content of the substances or mixtures of substances of about 10 to 16%. This moisture content can be achieved simply by adding or spraying water. Below this limit, only a small amount of mycotoxin becomes harmless.
Käsiteltävien aineiden tai aineseosten kosteuspitoisuus pidetään edullisesti korkeintaan 16 prosenttina.The moisture content of the substances or mixtures of substances to be treated is preferably kept at a maximum of 16%.
Tämän rajan yläpuolella mykotoksiini tosin muuttuu suuressa määrin vaarattomaksi, mutta käsittelyssä käytetyt kaasut voivat muodostaa enenevässä määrässä reaktiotuotteita, kuten etyleeniglykolia tai etyleenihydriiniä, jotka ovat terveydelle vaarallisia aineita.Above this limit, mycotoxin becomes largely harmless, but the gases used in the treatment can increasingly form reaction products, such as ethylene glycol or ethylene hydrine, which are hazardous to health.
Edelleen on havaittu, että esiteltyjä kosteuspitoisuuksia käytettäessä saavutetaan parhaat tulokset, jos käsittelyyn käytetään seosta, joka sisältää 40-60 tilavuusprosenttia etyleenioksidia ja noin 60-40 tilavuusprosenttia metyyliformiaattia. Usein on tarkoituksenmukaista käyttää inertillä kaasulla, kuten typellä tai hiilidioksidilla, laimennettua kaasuseosta.It has further been found that the best results are obtained when using the indicated moisture contents if a mixture containing 40-60% by volume of ethylene oxide and about 60-40% by volume of methyl formate is used for the treatment. It is often convenient to use a gas mixture diluted with an inert gas such as nitrogen or carbon dioxide.
Keksinnön mukainen menetelmä voidaan suorittaa siten, että haluttuun kosteuspitoisuuteen saatetut tai sen sisältävät käsiteltävät aineet tai aineseokset sijoitetaan suljettavaan astiaan, että tämä astia tyhjennetään sitten ilmasta ja että käsittelyyn käytettävä kaasu tai kaasuseos johdetaan ilmasta tyhjennettyyn säiliöön. Edullisesti käytetään kaasua tai kaasuseosta, jonka pitoisuus on 1000-1500 mg/1.The process according to the invention can be carried out by placing the substances or mixtures to be treated brought into or containing the desired moisture content in a sealable vessel, then evacuating the vessel and introducing the treatment gas or gas mixture from the air into the evacuated container. Preferably, a gas or gas mixture is used in a concentration of 1000-1500 mg / l.
Käsittelyaika riippuu käsiteltävien aineiden tai aineseosten laadusta ja irtopainosta. Käsittelyaika on edullisesti 6-16 tuntia.The processing time depends on the quality and bulk weight of the substances or mixtures to be treated. The processing time is preferably 6-16 hours.
Seuraava taulukko osoittaa, että käsiteltäessä aflatoksiini :tä sisältäviä homeen saastuttamia maapähkinöitä kaasuttamalla 16 tuntia seoksella, joka sisältää 50 tilavuusprosenttia etyleenioksidia ja 50 tilavuusprosenttia metyyliformiaattia pitoisuuden ollessa 1500 mg litraa kohti 3 61118 kaasutustilaa, aflatoksiinin pitoisuus laskee oleellisesti voimakkaammin, jos materiaalin kosteuspitoisuus on suurempi kuin 10 prosenttia. Tämä aflatoksiinin väheneminen on kaikissa tapauksissa riippumaton aflatoksiinin alunperäisestä määrästä.The following table shows that when aflatoxin-containing peanuts contaminated with mold are gassed for 16 hours with a mixture of 50% by volume of ethylene oxide and 50% by volume of methyl formate at a concentration of 1500 mg per liter of 3 61118 gasification conditions, the aflatoxin content is substantially lower per cent. This reduction in aflatoxin is in all cases independent of the initial amount of aflatoxin.
