Abstract
Active amino acid Ca, i.e., calcium oxide and/or hydroxide product coexistent with a slight amount of one or more amino acids and/or hydrolyzable amino acid derivatives is disclosed, which can be effectively absorbed into the human body and can deposit onto the bone with a high efficiency. Beverages containing same are also disclosed. The active amino acid Ca product is produced by calcining a calcium-containing material at 800.degree.-980.degree. C. in a calcining chamber free from oxygen, and subjecting the calcined product to a forced cooling step.
Claims10
An active amino acid calcium product comprising calcium of oyster shell origin in a layered structure and in a form selected from the group consisting of the oxide and the hydroxide, and one or more compounds selected from the group consisting of amino acids and hydrolyzable amino acid derivatives, including cystine, in an amount of 0.001 to 0.05% by weight, said compound being intimately coexistent with said calcium by being between layers of said layered structure of calcium or bound to said calcium.
A beverage containing the active amino acid calcium product, which is produced by dissolving the active calcium product described in one of claims 1, 2, 4, 5 or 6 in an aqueous solution of fermentation lactic acid.
A process for producing an active amino acid calcium product wherein a member selected from the group consisting of calcium oxide and calcium hydroxide of oyster shell origin is intimately coexistent with one or more amino acids and hydrolyzable amino acid derivatives, which process comprises electrically heating roughly ground oyster shell to 800.degree. to 980.degree. C. for 20 to 120 minutes in a calcining chamber free from oxygen and under reduced pressure or in vacuo, and forcibly cooling the calcined product.
