  • Patent number: 11208426
    Abstract: Systems and methods of making lactobionic acid are described. The systems include two-compartment cation bipolar electrodialysis assemblies having at least one cell that includes a cation ion-exchange membrane and a bipolar membrane. The membranes define the borders of a pair of flow channels for a separate (i) caustic stream and (i) purified lactobionic acid stream. Lactobionate ions in the lactobionic acid stream do not cross a membrane in the electrodialysis assembly, which reduces membrane fouling. The methods include passing a lactobionate salt through a two-compartment cation bipolar electrodialysis assembly. The electrodialysis assembly includes at least one two-compartment cation bipolar membrane cell, and separates the lactobionate salt into a caustic compound and the lactobionic acid. The assembly is designed so the lactobionate ions do not cross an ion exchange membrane in the assembly to form the lactobionic acid, which reduces membrane fouling.

  • Patent number: 11206846
    Abstract: Methods and systems for making a high-purity ?-lactalbumin composition are described. The composition may be made by providing a whey protein mixture, and adding an alkaline solution to the mixture to make the mixture alkaline and promote the aggregation of ß-lactoglobulin proteins. The alkaline whey protein mixture is filtered into a ß-LG aggregate composition and a ?-LA enriched composition. A final ?-lactalbumin enriched composition sourced from the ?-LA enriched composition is dried into the high-purity ?-lactalbumin composition (a powdered dairy composition) that is at least 70 wt. % ?-lactalbumin on a protein basis. A protease enzyme may optionally be added to the ?-LA enriched composition to form an enzymatically treated ?-LA enriched composition that becomes the source of the final ?-lactalbumin enriched composition.

  • Patent number: 10667538
    Abstract: Methods of making a powdered dairy composition are disclosed. The methods may include the steps of adding a sequestrant for calcium and rennet to a milk composition to make treated milk, and forming the treated milk into a milk powder. Powdered non-fat dry milk products are also disclosed. The products may include one or more milk proteins that have been enzymatically altered by chymosin, where the chymosin altered proteins are not coagulated. The products may also include one or more sequestants to bind calcium ions in the powdered product.

  • Publication number: 20200140756
    Abstract: Methods of extending a period of increased soil nitrogen levels in a soil are described. The methods include applying a soil enhancement agent to the soil, where the soil enhancement agent may include one or both of (i) lactobionic acid, and (ii) a least one salt of lactobionic acid. The methods also include applying a nitrogen-containing fertilizer to the soil. The soil treated with both the soil enhancement agent and the nitrogen-containing fertilizer has a higher level of soil nitrogen for at least a portion of a grown cycle of a crop planted in the soil than the same soil treated without the soil enhancement agent during the growing cycle of the crop.

  • Patent number: 9681676
    Abstract: Methods and systems for preparing soft or firm/semi-hard cheese are provided, as well as soft or firm/semi-hard cheese prepared by the methods. The methods typically involve the formation of a slurry that contains blended or molten cheese curd. A variety of ingredients can be introduced into the curd used to prepare the slurry, the slurry that is formed, or at other stages along the manufacturing process to tailor the performance and nutritional characteristics of the final cheese product. The slurry in some methods is directly processed to form a final cheese product. In other methods, the slurry undergoes various types of processing to achieve certain desired composition or performance requirements.

  • Patent number: 9578890
    Abstract: Methods are described for treating a whey protein mixture to increase a relative concentration of ?-lactalbumin protein in the mixture. The methods may include the step of adjusting a temperature of the whey protein mixture to about 10° C. or less, and adjusting the pH of the mixture to greater than 7. The may further include adding a protease enzyme to the whey protein mixture that selectively hydrolyzes ?-lactoglobulin protein in the mixture. The activity of the protease enzyme in the hydrolyzed whey protein mixture may be terminated before a substantial portion of the ?-lactalbumin protein has been hydrolyzed by the enzyme. In some instances, the whey protein mixture may also include glycomacropeptides that are selectively hydrolyzed with the ?-lactoglobulin protein. The ?-lactoglobulin and glycomacropeptide hydrolysates may be separated to produce an enhanced ?-lactalbumin protein composition for infant formula, among other products.
