Abstract
in English, Swedish

The present investigation clarified the effect of enzymes or other substances formed during the germination process on the vomitoxin level of contaminated oats. The studies found that oats containing vomitoxin germinated very poorly; the decrease in toxins was also slight. The amount of pure vomitoxin added to toxin-free grain decreased (barley 53%, oats 40%, wheat 20%) during germination (5 d). In homogenized mixture of germinated grain (2.4 and 7 d) and toxic grain no decrease in toxin amount occurred during a 1-7 day period. In contrast, when germinating toxin free grains and toxic oats in a grain mixture the toxin level decreased at first, but later rose considerably. On the basis of these results, the utilization of germination processes for the improvement of grain containing vomitoxin is of questionable value.

I detta arbete undersöktes effekten av enzym och andra substanser, som bildats under groningsprocessen, på vomitoxinhalten i kontaminerad havre. Resultaten visade att havre innehållande vomitoxin grodde mycket dåligt; minskningen av toxinmängden var också låg. Mängden av rent vomitoxin tillsatt tili toxinfri säd minskade (korn 53 %, havre 40 %, vete 20 %) under groning (5 d). I en homogeniserad blandning av grodd säd (2.4 och 7 d) och toxisk säd förekom ingen minskning av toxinmängden under en 1–7 dagars period. Vid groning av toxinfri säd och toxisk havre i blandning minskade däremot toxinhalten forst, men ökade senare betydligt. På basen av dessa resultat är användandet av groningsprocessen för att förbättra säd innehållande vomitoxin av ifrågasatt betydelse.
