Abstract

The penetration of methyl bromide into packages during treatment by various methods of vacuum fumigation has been further studied using bagged whalemeat meal of high protein content. Results are compared with those obtained in similar tests on bagged wheatfeed previously described. The time during the fumigation at which restoration of the pressure to atmospheric secures the maximum effective penetration of fumigant is established. Whether or not such enhancement of the effectiveness of penetration is desirable in the case of a highly sorptive product such as whalemeat meal is discussed in the light of evidence that effective concentrations of methyl bromide remain at the centre of the bag for a considerable period after the usual airing procedures. Airing at reduced pressure is suggested as being likely to be more effective than the procedures at present followed.
