Abstract: An edible, concentrated, proteinic hydrolysate is made by means of a method that includes enzymatically hydrolysing the proteins in an aqueous reaction mixture of a proteinic raw material and at least one enzyme, and deactivating the at least one enzyme. The volume of the obtained, aqueous hydrolysate is reduced by boiling down the hydrolysate to at least half volume to obtain a hydrolysate concentrate, to which salt is added until the saturation point of the hydrolysate concentrate has been essentially reached. The salt saturated soup concentrate does not need further preservation and has a long storage life at room temperature. The soup concentrate is easily diluted to a nutrient-rich, salt-tasted soup ready for being eaten.
