All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The effect of ultrafiltration, diafiltration, and preacidification of milk on the partition of specific milk components between retentate and permeate was studied. Percent retention (for any component Y) was determined as:
[1 - (%Y in soln. permeate/%Y in soln. retentate)] X 100 where %Y in soln. = [%Y / (%Y + %H2O)]
Simultaneous samples of retentate and permeate were taken at several points during each process. Percent retention of total solids, fat, total protein, rennet clottable nitrogen, lactose, total calcium, ionic calcium, sodium, phosphorous, and riboflavin was determined at each sampling point. Percent retention of β-carotene, vitamin B …
