Improvements in Dry Milk and Milk-like Products I, James Robinson Hatmaker, Gentleman, of No. 25 Rue de la Faisanderie, Paris, France, do hereby declare the nature of this invention to he as follows The object of my invention is to produce dry milk of improved digestibility. The albuminous portion of cow’s milk, for example, is somewhat difficult 0 of digestion, particularly by persons whose digestion is impaired or not fully developed, such as infants and invalids. This is principally due to the fact that such albuminous portion is in the form of an albumin. During natural digestion such albumin is changed into peptone. When sufficiently digested to lose its character as an albumin it becomes albumose—a term used broadly 10 throughout this specification to mean partly digested albuminous material that is between albumin and peptone in chemical transformation. To obtain dry milk the albuminous portion of which is albumose i.e. changed towards peptone, I treat liquid milk from which the water is to be evaporated to obtain dry milk with a digestive agent such as pepsin or pancreatin or with 15 a hydrolytic agent such as superheated steam. When the desired chemical change has been effected the water of the said milk is evaporated, preferably rapidly bv suitably exposing it to a high temperature, and dry milk of improved digestibility obtained. The albuminous constituents of this new dry milk resemble those of human 20 milk in chemical composition. An excellent dry product closely approximating dry human milk can be made by adding to the changed milk above described, before it is dried, a suitable proportion of cream, and by adding to it then or after it is dried, a suitable proportion of milk sugar. Thus a practically perfect .substitute for 25 mother’s milk can be obtained—dry humanized cow’s or other milk. Dried at a high temperature such milk is absolutely sterile soluble and conservable and of great convenience and value. Various preparations for invalids and others in which the albuminous con¬ stituents of. milk are changed into albumose may be made by adding to the ,30 changed milk above described such other suitable ingredients as may be desired, without departing from the spirit of my invention Milk deprived of all or any portion of its fat or to which fat has been added and milk the other constituents of which have been increased or diminished may be used as desired. 35 Dated this 11th day of February, 1904.
