Title: Improvements in and relating to the treatment of the flesh and other tissue of marinemammals
IPC: A23L17/10
Filed: 1934-07-05
Abstract: The flesh or other organic tissue of marine mammals after extraction according to the process of the parent Specification and separation of the liquid extract is subjected to a pressing operation and then dried, giving a product which may be used for animal food.  If the flesh or other tissue is not to be extracted immediately after the catch is made it may be subjected prior to storage to a pickling or smoking treatment, or both, which treatment may be preceded by a freezing or other cooling operation.  The pickling may be in a brine containing 10-16 per cent of cooking salt, or in a nitrite or other pickling brine. The drying may be effected in a drum drier in which the material is fed in the same direction as drying gases, or in conduit or multi-stage driers, and the moisture content may be reduced to 2 per cent or less.  The extraction and drying of subdivided whale meat and gutted dolphins are described, the extraction being effected by mixing with cold water and heating up to 96 DEG  C. preferably with stirring.  Specifications 415,305; and 420,040, [Group XIII], are referred to. p  The Specification as open to inspection under Sect. 91 comprises also, in the production of cattle food from the flesh or other tissue of marine animals, more particularly whales, seals and other marine mammals, subjecting the flesh to preservative treatment by pickling, smoking, cooling, freezing, &c. or combinations of these treatments, immediately after the catch is made.  In an example, seal flesh is cut up immediately after it is obtained and covered with a pickling brine containing cooking salt, sodium nitrate, sodium nitrite and sugar to which other electrolytes, e.g. lactic acid, may be added.  The solution may be isotonic with sea water or the meat juices, e.g. a salt mixture containing sodium, potassium, calcium, and magnesium ions in proportions giving a solution isotonic with the meat juice may be employed.  The liver, roe, brain, skin, intestines, spleen, hypophysis, ephiphisis, suprarenal capsules, cutiform gland, and other parts of the animals may be treated.  The preserved materials may be dried and ground.  This subject-matter does not appear in the Specification as accepted.ALSO:The flesh or other organic tissue of marine mammals after extraction according to the process described in the parent Specification and separation of the liquid extract is subjected to a pressing operation and then dried giving a product which may be used for human or animal food.

Specifications 415,305; and 420,040, [Group XIII], are referred to.  The Specification as open to inspection under Sect. 91 comprises also, in the production of edible products generally from the flesh or other tissue of marine animals, more particularly whales, seals and other marine mammals, subjecting the flesh to preservative treatment by pickling, smoking, cooling, freezing, &c., or combinations of these treatments, immediately after the catch is made.  In an example, seal flesh is cut up immediately after it is obtained and covered with a pickling brine containing cooking salt, sodium nitrate, sodium nitrite, and sugar to which other electrolytes, e.g. lactic acid, may be added.

The liver, roe, brain, skin, intestines, spleen, hypophysis, ephiphisis, suprarenal capsules, scutiform gland, and other parts of the animals may be treated.  The preserved products may according to their nature be used for human consumption or for the production of flesh extract, vitamins and hormones and other products.  Cattle food may be produced by drying and grinding the preserved materials.  This subject-matter does not appear in the Specification as accepted.
