Membrane filtered milk proteins varying in composition and functional attributes
InactiveUS6139901AEasy to separateReduce opacityMilk preparationProtein composition from milkUltrafiltrationFlavor
A process is described for treating an approximately neutral fluid milk composition, including milk protein concentrate and milk plus added whey, by selecting an alkali, adjusting the pH upward, heating, cooling, selecting an acid, and adjusting the pH down before ultrafiltering and, in a more preferred process, thereafter diafiltering the treated composition. Selection of the appropriate alkali, pH values, temperatures, acid, and membrane filter porosity results in improved yields of retentate proteins having selected compositions with improved utility, including a more palatable flavor, a brod range of solution viscosities, an increase in the solubility of the dried retentates in cold water to nearly 100%, and an increase in the calcium content of the membrane filtered retentate by about 50% compared to a similar retentate from standard milk. Appropriate selection of processing conditions can result in at least one filter permeate with a protein composition enriched in alpha lactalbumin, a protein that is highly beneficial for human nutrition.

Method for extracting lithium from salt lake brine
InactiveCN101767804AImplement selective extractionHigh extraction rateLithium compoundsHigh concentrationOrganic solvent
The invention provides a method for extracting lithium from salt lake brine, comprising the following steps: 1) mixing organic phase composed of salt lake brine, extracting agent and extracting medium with synergist, extracting the mixture and collecting the organic phase; 2) mixing the organic phase in step 1 with hydrochloric acid solution and carrying out back-extraction on the mixture, collecting aqueous phase to obtain aqueous solution of Lithium-ion; the step is characterized in that the extracting medium is hydrophobic ionic liquid. Compared with the traditional method for extracting lithium from salt lake brine with solvent gasoline as the medium, the method of the invention employs green and environmental-friendly ionic liquid as the medium; as a result, lithium salt extraction efficiency is improved, back-extraction acidity is lowered, what is more important is that environmental pollution and equipment corrosion due to use of a great deal of volatile organic solvent and high-concentration hydrochloric acid are avoided. In addition, the organic phase of the invention features fine cyclic applicability, thus greatly reducing production cost for extracting lithium from the salt lake brine.
