Estimating the term…
A processing method used for separating bone and oil from marine byproducts in the preparation of an endproduct. The byproducts are ground and then warmed to a relatively low temperature of approximately 70 deg.C. or less. The warmed material is passed to a refiner to separate the bone from the meat portions. The meat portion is transferred to a digestion tank where the endogenous enzymes perform a first stage digestion. Exogenous enzymes may be added and further digestion may take place for increased liquefaction of the meat portion. The exogenous enzymes can survive temperatures higher than the 60-65 deg.C. range so the liquified material can be heated during the further digestion to increase hydrolysis and pasteurize the product. Oil may be removed from the product by centrifuge following completion of either digesting step. Evaporation of the product may be used to increase the percentage of solid material. Alternatively, the oil may be removed after digestion without mechanically deboning the byproducts.
Method of removing oil from animal byproduct material comprising the steps of warming the temperature of said animal byproduct material to a temperature of less than 95 deg.C., digesting said animal byproduct material in a first digesting step to substantially liquify said animal byproduct material and centrifuging said animal byproduct material to remove said oil.
Method of removing bone from marine byproduct material comprising the steps of warming said ground marine byproduct material to a temperature less than 95 deg.C. and deboning said ground marine byproduct material.
Method for recovering bone and oil from marine byproduct material comprising the steps of grinding said marine byproduct material to reduce the size of solids therein, warming said marine byproduct material to a temperature of less than 70 deg.C., deboning said warmed marine byproduct material, digesting said marine byproduct material to substantially liquify said marine byproduct material and centrifuging said marine byproduct material following said digestion to remove said oil.
