Abstract
Abstract The invention relates to caseinates of oligo-elements, such as chromium, cobalt, copper, tin, iron, magnesium, manganese, molybdenum, nickel, silicon, vanadium and zinc, containing, for n times 100 grams of casein, from 3 to 100 milli-ion-grams of M n+ , where M represents the oligo-element(s) and n is an integer. The caseinates are prepared from casein by ion exchange in order to introduce the oligo-element(s) therein, followed by washing until a substantially constant composition is obtained. They may also be obtained from alkali metal caseinates. The caseinates of copper or iron may be used as a source of copper or iron with no catalytic activity on oxidation, particularly in infant and dietetic products.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
87 words
A process for preparing a soluble caseinate of at least one oligo-element containing, for n times 100 grams of casein, from 3 to 100 milli-ion-grams of M n+ , where M represents the oligo-element(s) and n is an integer, comprising treating an alkali metal caseinate, in solution with a solution of a salt of the oligo-element(s), washing the caseinate thus formed by at least one of ultrafiltration diafiltration and dialysis until the caseinate has a substantially constant composition, and dissolving the caseinate in water to form micelles.
Claim 2
Dependent Claim
87 words
A process for preparing a soluble caseinate of at least one oligo-element containing, for n times 100 grams of casein, from 3 to 100 milli-ion-grams of M n+ , where M represents the oligo-element(s) and n is an integer, comprising treating an alkali metal caseinate, in solution with a solution of a salt of the oligo-element(s), washing the caseinate thus formed by at least one of ultrafiltration diafiltration and dialysis until the caseinate has a substantially constant composition, and dissolving the caseinate in water to form micelles.
Claim 3
Dependent Claim
18 words
A process as claimed in claim 1, wherein the casein is a casein obtained by ultrafiltration of milk.
Claim 4
Dependent Claim
28 words
A process as claimed in claim 1, wherein the oligo-element is at least one of chromium, cobalt, copper, tin, iron, magnesium, manganese, molybdenum, nickel, silicon, vanadium and zinc.
Claim 5
Dependent Claim
29 words
A process as claimed in claim 1, wherein the alkali metal caseinate is prepared by contacting casein in solution with a cation exchange resin loaded with alkali metal ions.
Claim 6
Dependent Claim
19 words
A process as claimed in claim 1 wherein calcium is introduced into the caseinate in addition to the oligo-element(s).
