ABSTRACT:
A shellfish extract concentrate is prepared by subjecting an extract of a shellfish (exclusive of oyster) having a solid concentration not higher than 30% by weight to an adsorption purification treatment with an adsorbent composed mainly of a water-insoluble inorganic magnesium compound, which has a specific surface area of at least 50 m.sup.2 /g, and concentrating the refined liquid in a substantially non-oxidizing atmosphere. In this shellfish extract concentrate, black and blackish brown coloring components are not contained, and flavor components and nutrients are not substantially lost. Accordingly, this shellfish extract concentrate is excellent in taste, flavor and hue.
