PRODUCTION OF MARINE PRODUCT CONCENTRATED EXTRACT IMPROVED IN FLAVOR, THE CONCENTRATED EXTRACT AND SEASONING

摘要

PURPOSE: To obtain a concentrated extract having natural and rich flavors of marine products and improved in the fragrance, and further to obtain a seasoning containing the extract. ;CONSTITUTION: A concentrated solution containing the flavor ingredients of marine product raw materials is subjected to the adjustment of pH, added to a concentrated solution extract containing the taste ingredients of the marine product raw materials to produce the marine product concentrated extract improved in the flavor. The concentrated solution is obtained by adding water to various kinds of the marine product raw materials, distilling the mixture, recovering the distillate containing flavor ingredients and subsequently concentrating the recovered distillate. The distillation is performed at a middle or high temperature suitable for the natures of the raw materials. The concentration is performed by applying a reverse osmosis treatment using a tight reverse osmosis membrane having a salt-intercepting constant of ≥99.5% to the flavor ingredient-recovered distillate under a high pressure of ≥50kgf/cm². When the flavor ingredients are concentrated with the tight reverse osmosis membrane, the pH of the raw solution is controlled to ≤4. The concentrated solution extract containing the taste ingredients of the marine product raw materials is obtained by extracting the taste ingredients from the raw material residues from which the flavor ingredients are vacuum- distilled off.;COPYRIGHT: (C)1997,JPO
