Abstract
A decolorized oyster extract concentrate is formed by an adsorption purification treatment using a specific inorganic lamellar magnesium phyllosilicate compound and a concentration treatment. Coloring components can be effectively removed without substantial reduction of the contents of taste components and nutrients. The decolorized oyster extract concentrate is very valuable as a seasoning or healthy food.
Claims9
A process for the preparation of an oyster extract concentrate, which comprises subjecting an oyster extract having a solid concentration not higher than 30% by weight to an adsorption purification treatment at a temperature of 0.degree. to 100.degree. C. for at least 1 minute with an adsorbent composed mainly of a water-insoluble synthetic lamellar magnesium phyllosilicate, which has a specific surface area of 100 to 800 m.sup.2 /g, in amount of 0.5 to 20% by weight based on the oyster extract and concentrating the refined liquid in a substantially non-oxidizing atmosphere so that the solid concentration is at least 5% by weight.
