The present invention relates to a method for preparing a blood plasma
powder, in which (1) a fibrinogen concentrate having a fibrinogen content
of at least 1 percent by weight is prepared from blood plasma, and in
that (2) said fibrinogen concentrate is spray-dried to form a powder,
apparently intended for use in foodstuffs, in such a manner that the
temperature of the fibrinogen itself is maintained at less than
60.degree. C. Furthermore, the invention relates to a method for bonding
together pieces of foodstuff and to a method for increasing the
consistency of a liquid or semi-solid foodstuff.
