摘要:
A decolorized oyster extract concentrate is formed by an adsorption purification treatment using a specific inorganic magnesium compound and a concentration treatment. Coloring components can be effectively removed without substantial reduction in taste and nutrient content. The decolorized oyster extract concentrate is very valuable as a seasoning or health food.
摘要:
A concentrated shellfish extract 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 m²/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.
摘要:
A hydraulic cement composition useful in, for example, the production of molded structures and the treatment of industrial wastes, comprises (A) (i) a water-soluble alkali metal borosilicate or (ii) a water-soluble alkali metal silicate and an alkali metal borate soluble in an alkaline aqueous solution, (B) silicon polyphosphate, (C) an alkali metal silicofluoride and (D) substantially amorphous barium silicate in which the BaO/ SiO 2 molar ratio is from 1/2.5 to 1/6.
