PURPOSE:To obtain the title galactomannan useful as a food additive, by mixing an aqueous solution of galactomannan with a second aqueous solution containing a readily water-soluble substance in a specified proportion followed by dehydration into powder. CONSTITUTION:Firstly, an aqueous solution of a galactomannan containing <=25wt.% of galactose, such as locust bean gum is mixed with a second aqueous solution containing a readily water-soluble substance such as carageenan or glucose in the weight ratio, on a solid basis, of 10/1-1/100 (pref., 5/1-1/10). Thence, the resultant aqueous solution is dehydrated using e.g., alcohol precipitation technique or spray drying process into powder. |
