Frozen krill blocks with shells obtained through a process of making quantitative blocks by freezing means at 30℃ to -10℃ and frozen egg white blocks prepared separately were combined at 70 to 95℃.
%: At a ratio of 5 to 30%, the meat is pulverized to micron order using a continuous frozen meat emulsifier equipped with a coarse crushing section, a mixing section, and a pulverizing section, and the finely pulverized product is filled, sealed, and refrozen. The emulsifying power of the egg white can mask enzymes attached to the finely ground krill, and by simultaneously pulverizing the shell (calcium content), it is possible to ensure alkalinity. In other words, compared to conventional production methods, the amount of salt-soluble proteins reduced by storage in seawater is also reduced by protease (proteolytic enzyme).
The self-digestion caused by the adhesion of gastrointestinal substances to the digestive organs can also be suppressed, and the intended purpose can be fully achieved, which is an excellent effect.
