해양심층수를 이용한 다시마 추출물의 두부응고제 특성

Abstract

We investigated the characteristics of various tofu coagulants extracted from sea tangle using treated deep ocean water (DOW) as the solvents. The coagulants were typical solutions extracted from sea tangle using raw DOW and strongly electrolyzed acidic (SAC) or alkaline (SAK) water. The total dissolved solids (TDS), NaCl and electric conductivity were increased in the coagulant solution extracted by SAC than the others. In the coagulant solutions extracted by acidic electrolyzed solvent, aspartic acid content (13.5 ㎎/100g) was higher than others (11.2 and 12.1 ㎎/100g). The Tofu obtained using coagulants extracted with treated DOW had water contents ranging from 79.55% to 80.04%. The contents of crude protein (12.1g/100g) and Na, Ca, K and Mg were relatively higher than general Tofu commercially available. Therefore, coagulant solutions extracted from sea tangle using treated DOW can be used to develop natural high-grade tofu for practical use.
