    I am working with a company that has used a readily available enzyme to
    process extracted livers from the spiny dogfish shark under a low heat
    process. The oil fraction is then taken off the top after settling and is
    double filtered through a 100 mesh fabric filter. Pretty crude. We have
    found this oil fraction then separates over time into a clear fraction and a
    cloudy chalky heavier fraction. The latter represents about 5-10% of the
    total volume.

    Does anyone of the listserve have any experience with appropriate processing
    options that can move us from primitive to advanced in order to satisfy GMP
    and HAACP requirements for 'food for human consumption' (e.g. as a marine
    oil as a human nutritional supplement and/or as a feed ingredient for
    animals and fish.)

    Due to the particular physiology of sharks, does anyone know what we should
    be watching out for in terms of flavor/odor properties in this oil that may
    need to be removed through some method?

    We are also looking for introductions to appropriate markets as we get our
    processing system in place.

    Many thanks,
