Claims11
A process for preparing liquified fish silage which comprises admixing unground fish solids having dimensions up to 6 inches by 15 inches with liquified fish silage in a ratio in the range of from 10:1 to 1:10 by weight and an additive present in at least an amount capable of initiating and accelerating liquifaction of said fish solids, the additive being selected from the group consisting of organic acids, mineral acids, salts thereof, and enzymes;
- and effecting liquifaction of said fish solids in the presence of said liquified fish silage and at a temperature of at least 20.degree. C.
A cyclic process for the production of liquified fish silage which process comprises mixing unground fish solids having dimensions up to 6 inches by 15 inches with liquified fish silage from a previous cycle in a ratio in the range 10:1 to 1:10 by weight and from 0.5 to 30% by weight, expressed as a percentage by weight of fish solids, of an additive capable of initiating and accelerating liquification of the fish solids, the additive being selected from the group consisting of organic acids, mineral acids, salts thereof and enzymes;
- effecting liquifaction of the fish solids to liquified fish silage in the presence of the preformed liquified fish silage at a temperature of at least 20.degree. C.;
- withdrawing at least a portion of the resulting liquified fish silage;
- adding to the remaining liquified fish silage if only some is withdrawn, or to recycled liquified fish silage if all is withdrawn, a further quantity of fish solids of the dimensions and in the weight ratio previously specified, and a further quantity of an additive as previously specified and in the percentage weight range previously specified;
- and repeating the cycle.
