Idaho Patent of the Month – October 2021
Milk is used to create a variety of products – from cheese to cream to yogurt – but needs to be separated into different components to do so. Memtec LLC has developed a system that effectively separates milk into these components. By separating the milk into these components, the nutritional profile can be further exploited to produce the best dairy products.
They designed a filtration system which can use alpha-filtering for both wide-pore and ultra-filtering methods. First, the dairy product is filtered through a series of wide-pore filters to produce wide-poor retentate and permeate. This category of milk specifically includes casein and beta-lactoglobulin. The next filtration step uses ultra-filtered permeates which produce a product with lactose and alpha-lactalbumin. A third filtration step uses nano-pores to further filter the product. Finally, a reverse osmosis filtration is performed on these nano-filtered permeates to produce a final product. These different filtration products can then be combined in varying formulations to produce the desired end product, adding sweeteners and enzymes as needed.
