The present invention relates to protein ingredients, such as protein concentrates and protein isolates, having improved handling properties, in particular exhibiting higher bulk density and flowability, while having a low dustiness compared with their reference on the market. The present invention also relates to compositions comprising said protein ingredients. The present invention further relates to a method for obtaining protein ingredients having improved handling properties, wherein said method comprises a compaction step followed by a milling step and, optionally, a classifying step. The claimed method advantageously does not require any thermal treatment, thereby keeping the native properties of the protein ingredients, while being of a low cost.
