The ultrafiltration membrane technique is said to eliminate unwanted flavours and tastes in water without the use of chemicals but preserves its natural mineral content.
32.
The " washing " or desalting step can be performed by ultrafiltration, dialysis, acylated gelatin ), or a classic noodle washing method.
33.
Ultrafiltration also results in a milk that retains more nutrients and proteins, and the cheese has a relatively high fat content of 60 %.
34.
Using an ultrafiltration system to purify and concentrate the protein, they produce WPI at about 90 % pure protein for use in nutritional supplements.
35.
The current pre-treatment of seawater desulphonation uses ultrafiltration modules that have been designed to withstand high temperatures and pressures whilst occupying a smaller footprint.
36.
With efficient modern methods such as ultrafiltration, 10 to 20 % of solids or more remain after the whey is mixed with cream and reduced.
37.
Microfiltration, Ultrafiltration and Reverse Osmosis are the three main competing processes, each one is able to filter to a certain extent depending on its pore size
38.
Ultrafiltration membranes have pore sizes ranging from 0.1 �m to 0.01 �m and are able to retain proteins, endotoxins, viruses and silica.
39.
Nanofiltration membranes have pore sizes from 1-10 Angstrom, smaller than that used in microfiltration and ultrafiltration, but just larger than that in reverse osmosis.
40.
The second method, membrane filtration, typically a combination of microfiltration and ultrafiltration, uses molecular size as the basis for separating components from the whey stream.
