Abstract
Abstract A process for the manufacture of liquid, pasty or powdery whey products in which the proportions of protein, lactose and ash substantially correspond to those in skimmed milk, and which are suitable as an additive for foodstuffs and feeds, consists of the steps of ultrafiltering whey in a ratio of about 1:20, by volume, drying the resulting concentrate (if necessary), and mixing it with whey, whey concentrate or whey powder in a ratio of about 4:5, relative to the solids.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
166 words
The process for the manufacture of a liquid, paste or powder whey product in which the proportions of protein, lactose and ash substantially correspond to those in skim milk and which whey product is suitable as an additive to foodstuffs and feeds, which comprises the steps of: subjecting whey, as a starting material, to an ultrafiltration membrane separation to separate said whey starting material into a permeate fraction and a retentate fraction in which the volume of said retentate fraction is about 1/20th of the volume of said whey starting material and which retentate fraction contains a higher proportion of protein and lower proportions of lactose and ash than said whey starting material; and then mixing said retentate fraction with a whey concentrate containing at least 50 wt. % of solids or dry whey powder, wherein the mixing ratio of (1) said retentate to (2) said whey concentrate or said dry whey powder, is about 4:5, calculated as the solids, whereby to obtain said whey product.
Claim 2
Dependent Claim
166 words
The process for the manufacture of a liquid, paste or powder whey product in which the proportions of protein, lactose and ash substantially correspond to those in skim milk and which whey product is suitable as an additive to foodstuffs and feeds, which comprises the steps of: subjecting whey, as a starting material, to an ultrafiltration membrane separation to separate said whey starting material into a permeate fraction and a retentate fraction in which the volume of said retentate fraction is about 1/20th of the volume of said whey starting material and which retentate fraction contains a higher proportion of protein and lower proportions of lactose and ash than said whey starting material; and then mixing said retentate fraction with a whey concentrate containing at least 50 wt. % of solids or dry whey powder, wherein the mixing ratio of (1) said retentate to (2) said whey concentrate or said dry whey powder, is about 4:5, calculated as the solids, whereby to obtain said whey product.
Claim 3
Dependent Claim
55 words
The process according to claim 1 in which said retentate fraction contains from 2.50 to 3.92 wt. % of ash, from 70.71 to 75.00 wt % of protein and from 24.64 to 31.07 wt. % of lactose, calculated as the solids, and wherein the weight ratio of protein to lactose is from 2.41:1 to 2.85:1.
Claim 4
Dependent Claim
28 words
The process according to claim 1 or claim 2 in which the retentate is dried prior to mixing it with said whey concentrate or said dry whey powder.
Claim 5
Dependent Claim
34 words
The process according to claim 1 or claim 2 in which the mixture of said retentate with said whey concentrate or said dry whey powder is concentrated or dried to obtain said whey product.
