Abstract
Abstract A method of preparing metal proteinates from natural proteinacous material without destroying naturally occurring vitamins and hormones which comprises neutralizing a protein containing material, subjecting said material to enzymatic hydrolysis, adjusting the enzymatically digested hydrolysate to a slightly basic pH and adding a metal salt thereto to form a metal proteinate precipitate. The proteinate thus formed is a chelate of polypeptides with metals and is substantially free from metal salts and single amino acid proteinates.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
39 words
A composition of matter comprising naturally occurring proteinaceous tissues selected from the group consisting of muscle, heart, liver, thymus, brain, spleen, kidneys, duodenum, pancrease, and orchic a portion of which have been enzymatically hydrolyzed by a protease to produce
Claim 2
Dependent Claim
39 words
A composition of matter comprising naturally occurring proteinaceous tissues selected from the group consisting of muscle, heart, liver, thymus, brain, spleen, kidneys, duodenum, pancrease, and orchic a portion of which have been enzymatically hydrolyzed by a protease to produce
Claim 3
Dependent Claim
26 words
A composition of matter according to claim 1 wherein the naturally occurring vitamins and hormones have not been destroyed by the hydrolysis process and remain intact.
Claim 4
Dependent Claim
31 words
A composition of matter according to claim 2 wherein the bivalent biologically essential metals are selected from the group consisting of iron, copper, zinc, manganese, cobalt, chromium, calcium, magnesium and vanadium.
Claim 5
Dependent Claim
