摘要: Abstract Along with the increase in fresh cheese production market, there is a concomitant volume of its by-product, lactic acid whey (LAW). This type especially rich organic acids and ash content, making it more difficult to develop applications for human food. In view hygroscopicity, this fact clearly most dry properly, high level mineralization narrows potential uses nutritional reasons. The aim study was evaluate ability use nanofiltration (NF) partially demineralized LAW powder regard dryability concentrate quality at semi-industrial scale. strong selectivity demineralization process results 30% reduction content between 46 60% monovalent ions. NF improved as well. Moreover, energy cost overall reduced by 43%. These elements highlight benefit inserting an industrial step into processing should significantly contribute powder.
