Cereals and Milled Foods. At atmospheric pressure, ethylene oxide does not penetrate well into bagged and packaged cereals and milled products (Lepigre, 1947). It is used for this type of material mainly in vacuum fumigation. Its use as a fumigant for treating bulk grain by recirculation in silos is discussed in Chapter 10. Dried Fruit

Mill scale, often shortened to just scale, is the flaky surface of hot rolled steel, consisting of the mixed iron oxides iron(II) oxide (FeO), iron(III) oxide (Fe 2 O 3), and iron(II,III) oxide (Fe 3 O 4, magnetite).. Mill scale is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling red hot iron or steel billets in rolling mills.
