    • A heat-sterilized or frozen seafood product having quality closer to that in a raw state thereof is provided. The invention intends a heat-sterilized seafood product which maintains the same appearance, taste and texture as those in a raw state thereof, a frozen product of the same, and cooked foods using those products. The heat-sterilized seafood product of the invention is featured in that, as compared with a product boiled at the same heating temperature, an outer part of the heat-sterilized seafood product shows a lower degree of protein degeneration, and an inner part thereof shows a comparable or higher degree of protein degeneration; and/or drips generated when the heat-sterilized seafood product is frozen and then thawed are clear and have a low level of turbidity; and/or when the heat-sterilized seafood product is frozen and then thawed, a reduction of the yield, a change of the appearance, the number of bacteria, and an outflow of the taste substances are all small. The heat-sterilized seafood product is obtained by heat-sterilizing an seafood product by ohmic heating, preferably ohmic heating wherein the seafood product is heated with an aqueous solution employed as a medium, and more preferably ohmic heating wherein the seafood product is heated to a temperature of not lower than 60null C. but lower than 90null C. and the aqueous solution is heated to a temperature lower than the temperature of the seafood product by a range of not less than 0null C. but less than 25null C.
    • 提供了一种质量接近原始状态的热灭菌或冷冻海产品。 本发明涉及一种热灭菌的海产品,其保持与其原始状态相同的外观,味道和质地,其冷冻产品和使用这些产品的熟食。 本发明的热灭菌海产品的特征在于,与在相同加热温度下煮沸的产品相比,加热灭菌海产品的外部部分的蛋白质退化程度较低,其内部显示出 相当或更高程度的蛋白质变性; 和/或当热灭菌的海鲜产品冷冻然后解冻时产生的滴液,并且具有低的浊度; 和/或当热灭菌的海鲜产品冷冻然后解冻时,产量的降低,外观的变化,细菌的数量和味道物质的流出都很小。 热灭菌的海鲜产品通过欧姆加热对海鲜产品进行加热灭菌而获得,优选欧姆加热,其中海鲜产品用作为介质的水溶液加热,更优选欧姆加热,其中将海产品加热至 温度不低于60℃但低于90℃,并将水溶液加热至不低于海产品的温度的温度不低于0℃但小于25℃ 。
