HIGH OCTOPINE-CONTAINING FISH AND SHELLFISH EXTRACT, METHOD FOR PRODUCING THE SAME, AND FOOD AND DRINK CONTAINING THE HIGH OCTOPINE-CONTAINING FISH AND SHELLFISH EXTRACT

摘要

PPROBLEM TO BE SOLVED: To provide a fish and shellfish extract significantly increased in the content of octopine, for the purpose of enabling an effective amount of the octopine to be simply and safely ingested, to provide a method for producing the same, and to provide food and drink containing the high octopine-containing fish and shellfish extract. PSOLUTION: This fish and shellfish extract is produced by subjecting an octopine-containing extract which is extracted from fish and shellfish to molecular fractionation treatment, so as to concentrate the extract to have an octopine content of 2-60 mass % based on a solid content of the extract, wherein one, two or more kinds of members selected from a reverse osmosis membrane, an ultrafiltration membrane, and an ion exchange resin are used for subjecting the extract to the treatment. A reverse osmosis membrane having a common salt-blocking ratio of 10-50%, an ultrafiltration membrane having a fractionation molecular weight of 10,000, and a strongly acidic ion-exchange resin are each preferably used as a means for the molecular fractionation. When a high octopine-containing composition is mixed into the food and drink as a seasoning or a raw material component, the food and drink which bring out flavor of the composition is obtained.
