Title: Preservable ground meat of fish
Inventor: NOJIMA SEIJI
IPC: A23L17/00
Filed: 1988-02-29
Abstract: PURPOSE:To prevent the occurrence of aging and regeneration and to enable long-term preservation of ground meat, by mixing ground lotus root and bean curd into ground meat of fish and grinding the mixture. CONSTITUTION:Ground fish meat is mixed with ground mixture of about 15% of lotus root and about 15% of bean curd and the mixture is ground. Since the fibrous particles 5 of lotus root and particles 6 of bean curd are dispersed between the protein particles 1 of the ground meat to suppress the mutual bonding of the protein particles and prevent the occurrence of aging. Since bean curd does not cause excessive coagulation, the aging can be prevented and the loss of springiness can be replenished. When the ground meat is heated, the protein particles form a network structure together with the lotus root particles 5 and the bean curd particles 6 and form a KAMABOKO (steamed fish paste). Since the agglomeration of protein particles 1 is inhibited by the lotus root particles 5 and the bean curd particles 6, the occurrence of regeneration can be prevented. The preservability of the product can be further improved by the addition of ground mixture of MISO (fermented bean paste). The ground meat can be prepared in large quantity at a time and a low cost and is suitable for the long-distance transportation.
