Abstract

Described is a method for manufacturing a protein powder containing at least partly non-coagulated proteins. The method includes the steps of grinding a solid proteinaceous raw material to obtain a solid ground protein, heating the ground protein to a temperature T below its coagulation temperature TP such that fat contained in the ground protein melts, separating the melted fat from the ground protein to obtain a defatted protein fraction, and drying the defatted protein fraction in a drier at a temperature TD, whereby a protein powder comprising at least partly non-coagulated proteins is formed. Also described is a protein powder that includes at least partly non-coagulated proteins obtained by said method, and a use of a at least partly non-coagulated protein powder in a foodstuff for humans or animals, such as animal feed.

Abstract

The invention discloses a method for manufacturing a blood meal comprising non-coagulated proteins. The method (200) comprises the steps of heating (220) a first part of non-coagulated raw blood (1) to a temperature T above its coagulation temperature TC, such that proteins in the non-coagulated raw blood (1) coagulate and coagulated blood (2) is obtained. Secondly, the method comprises separating (230) water (3) from the coagulated blood (2) to obtain dewatered coagulated blood (4) and adding (240) the dewatered coagulated blood (4) and a second part of non-coagulated raw blood (1') to a dryer (100). The ratio between the second part of non-coagulated raw blood (1') and the first part of non-coagulated raw blood (1) is 1:10 to 2:3. Finally, the method (200) comprises drying (250) the dewatered coagulated blood (4) and the second part of non-coagulated raw blood (1') in the dryer (100), whereby a blood meal (10) partly comprising non-coagulated proteins is formed. The invention further relates to a blood meal (10) formed from the method (200) and the use of the blood meal (10) in a foodstuff.
