Diafiltration based cow’s milk partial demineralization by membrane filtration process – parameter and technology estimations

Abstract

Milk and dairy products contain a number of biological materials that are essential for the human body, for example proteins, lipids, vitamins and minerals. In this study the application of membrane filtration based milk partial demineralization is detailed. The main point of the partial demineralization is to reduce the monovalent ions (Na + , K +) but to keep the divalent ions (Ca 2+ , Mg 2+) content. The experiments were carried out using laboratory ultra-and nanofiltration units. Comparing the separation behavior of the membranes it was found that the investigated membranes are suitable for the partial demineralization. The result of the Lowry test showed that the protein concentration is higher in the retentates of all membrane filtrations than in the permeates.

Evaluation of lablab bean (Lablab purpureus (L.) Sweet) sprout milk fortificated with eggshell extracted calcium

“…Water content in milk is very high (87.5%) with specific milk sugar (lactose) of 5%, protein of 3.5%, and fat around 3-5%. Milk is a very good source of calcium, phosphorus, and vitamin A (Csighy et al, 2018). Milk from animals contains lactose that cannot be digested properly by people with lactose intolerance condition.…”
