    Abstract: A process for producing a protein isolate from an oilseed meal, and the isolate thus obtained, said isolate comprising proteins and an amount of 4 wt. % or less of phytic acid, said amount of phytic acid being by weight of proteins in said isolate. The process may comprise the following steps:



    a) providing an oilseed meal;
    b) mixing the oilseed meal with a first aqueous solvent to form a slurry at a pH ranging from 6 to 7.8, said slurry having a solid phase;
    c) separating said solid phase from said slurry,
    d) mixing said separated solid phase with a second aqueous solvent at a pH ranging from 1 to 3.5, preferably from 2 to 3, to form a mixture said mixture having a liquid phase;
    e) separating said liquid phase from said mixture formed in step d);
    f) f1) mixing the separated liquid phase to a phytase at a temperature and a pH suitable for phytase activity to obtain a mixture having a liquid phase and a solid phase;
    and/or
    f2) mixing the separated liquid to a salt, to obtain a resulting liquid composition having a molar concentration of said salt ranging from 0.05M to 0.5M, at a temperature ranging from 40° C. to 70° C., to obtain a mixture having a liquid phase and a solid phase;
    g) precipitating a solid phase from the liquid of step f) for example by a cooling down step of the mixture to a temperature of 30° C. or less;
    h) separating said solid precipitate from the liquid of step g) said liquid comprising a water-rich liquid phase and an oil-rich liquid phase;
    i) separating said water-rich liquid phase from said oil-rich liquid phase,
    j) subjecting said water-rich liquid phase obtained in step i) to one or several membrane filtration(s) to obtain a protein isolate; and
    k) optionally, drying said protein isolate to obtain a dry protein isolate.

    Abstract: A transmission method and device are provided for taking account of an echo. The method and the device adapt the send power mask to take account of an echo's power estimated on the basis of an echo function, the echo being due to the transmission by a transmission channel of a sequence sent by the sender device.
