Sardine, mackerel or other marine animal creams - preserved in tubes after addn. of fats and seasonings with final sterilisation

摘要

Sardine, mackerel or other marine animal creams, for preservation in tubes, are made by preparing and pounding the fish, shell-fish or molluscs and adding fatty substances and food seasonings; the cream obtd. is filtered and introduced into tubes. These are then sealed and undergo a heat treatment; this is accompanied by a counter-pressure to prevent their deformation during this heat sterilisation operation. The tubes are made of a malleable material, such as pure aluminium of food quality; they are enamelled before filling and are afterwards packed and distributed in the usual manner. The final prod. has all the qualities of a true preserved food; it remains wholesome and retains its properties for a long period of time. The fatty substances added during pounding may consist of a butyric fat, butter or a vegetable oil such as ground nut oil. The seasonings added before the final filtrations are thick tomato soup, salt, sugar and spices.
