Abstract
The present invention provides a process for extracting minerals from mineral-rich oysters and furthermore provides an oyster extract containing the minerals, and taurine, glycogen, and nucleotides. First, raw oysters are subjected to hot water extraction to obtain soluble ingredients and to remove unwanted components, and then the residue is extracted with acid solution of pH 2 to 4.. The extract is neutralized with alkali to obtain a precipitate having a high content of minerals such as zinc. The oyster extract obtained by this process contains zinc in the amount of 6% to 13% by dry weight.
Claims9
An oyster extract containing 6% to 14% zinc by dry weight, which mineral is combined with peptides of the oyster.
An oyster extract mixture containing 0.05% to 0.4% zinc by dry weight, which mineral is combined with peptides of the oyster.
A process for manufacturing an oyster extract comprising the steps of extracting oyster with hot water, then adjusting the oyster residue to pH 2 to 4, filtering the residue extract and neutralizing the pH of the filtered extract to obtain a high-mineral precipitate of the oyster extract.
