Rational use of resources of red algae Ahnfeltia tobuchiensis

Abstract

Resources of red algae Ahnfeltia tobuchiensis (Kanno et Matsubara) and volumes of this alga storm releases in the Okhotsk and Japan Seas are considered. In the last decade, the stable commercial stocks are maintained in the Izmena Bay (about 70∙103 t) and Peter the Great Bay (about 45∙103 t); the field in Aniva Bay is depressed with a tendency to disappear. Storm releases accumulate annually on shores of Peter the Great Bay about 5,000 t of A. tobuchiensis suitable for use in agriculture. Prospects for using the red algae as a source of various chemical compounds in the food industry and agriculture are described. Particular attention is paid to polysaccharides, pigments, polyphenols, peptides and other biologically active compounds. Recommendations are given for processing the storm emissions of A. tobuchiensis, primarily in organic farming.
