Abstract

Milk mineral, which is also called milk calcium, was recovered from concentrated skim milk ultrafiltration permeate (CUFP). Lactose, the major constituent of CUFP, was crystallized by the addition of ethanol; lactose precipitation was observed to increase as the ratio of CUFP to ethanol increased. The calcium content of CUFP remained constant at a CUFP to ethanol ratio of 1:2, while it significantly decreased at a CUFP to ethanol ratio of 1:4. When ethanol (95%, v/v) was reused to precipitate lactose out of CUFP, 85% of the initial lactose precipitated out, while 82% of calcium remained soluble in the CUFP after storage for 24 h.
