PURPOSE:To obtain walleye pollack roes (MENTAINOKO) having improved preservation quality at ordinary temperature, by mixing roes of a walleye pollack free of the sinew part with common salt and ethanol, and containing the resultant roes in a closed container. CONSTITUTION:The sinew part is removed from roes of a walleye pollack, and the roes are mixed. Common salt in a concentration corresponding to 5-13% based on the weight of the product and ethanol in an amount corresponding to 2-5% based on the weight of the product are added and mixed therewith. The resultant mixed roes to the walleye pollack (MENTAINOKO) are contained in a closed container to give the aimed product. If the common salt concentration is higher than 13%, the salty taste is too strong to meet the needs in recent years for reducing the salt content. On the other hand, if the common salt concentration is lower than 5%, the taste is insufficient. In order to improve the preservation quality of the MENTAINOKO without increasing the salty taste, the common salt and ethanol are used together. A packaged container or tubular container made of a composite packaging material, so-called laminated tubular container or glass bottle can be effectively used as the closed container. |
