抄録

Soybean oil to which had been added 9 pyrethroid pesticides (pyrethrins, cyhalothrin, deltamethrin, permethrin, cypermethrin, cyfluthrin, fluvalinate, fenvalerate and flucythrinate, 5mg/kg each) was refined during degumming, alkali-refining, bleaching and deodorization. The amounts of the pesticides in the oil were determined immediately subsequent to each of these processes.<BR>All pesticides remained for the most part in the oil during degumming, alkali-refining and bleaching. During deodorization at 260°C, pyrethrins remarkably decreased, while the amounts of cyhalothrin, deltamethrin, permethrin, cypermethrin and cyfluthrin were reduced by nearly a half. Only slight decrease was noted in fluvalinate, fenvalerate and flucythrinate under the same conditions.
