Abstract
Market product of purple laver obtained from Korea was subjected to the microbiological assay method for 18 kinds of amino acid determination.
Acid or alkali hydrolysates of sample powder and its sodium tungstate extracts were prepared for total and free amino acid assay.
Total amino acid pattern of purple laver included 37% 8 essentials in 18 acids assayed. Aspartic and glutamic acids, arginine, serine and valine were found to be included in relatively high potency (Table 1.). When compared with FAO reference pattern, the essential amino acid of purple laver showed marked shortage in the level of those containing sulfur (Fig. 1.). The eighteen kinds of free amino acid assayed occupied 2.9% in the sum of 18 total. In the free amino acid pattern, glutamic acid showed conspicuously high potency and was followed by alanine.
