Abstract

A low temperature rendering process for converting animal trimmings to a meat product which can be classified as finely textured meat. The low temperature rendering process includes the steps of heating desinewed animal trimmings in a heat exchanger having a first-in and first-out arrangement to provide heating of the desinewed animal trimmings to a temperature in the range of about 90.degree. F. to about 110.degree. F. to form a heated slurry; separating a solids stream and a liquids stream from the heated slurry, the solids stream containing an increased amount of protein and moisture, and the liquids stream containing an increased amount of tallow, water soluble protein, and moisture; separating a heavy phase and a light phase from the liquids stream, the heavy phase containing an increased amount of moisture and water soluble protein, and the light phase containing an increased amount of tallow; and combining the solids stream and the heavy phase to form a meat product.

Dependent claims

A low temperature rendering process for converting animal trimmngs to meat product, said low temperature rendering process comprising the steps of:

(a) heating animal trimmings in a heat exchanger having a first-in and first-out arrangement to a temperature in the range of about 90.degree. F. to about 120.degree. F. to form a heated slurry;
(b) feeding the heated slurry to a decanter and separating the heated slurry into a solids stream and a liquids stream, the solids stream containing an increased weight percent of protein and moisture compared with the weight percent of protein and moisture in the heated slurry, and the liquids stream containing an increased weight percent of tallow compared with the weight percent of tallow in the heated slurry;
(c) feeding the liquids stream from the decanter to a separator and separating the liquids stream into a heavy phase and a light phase, the heavy phase containing an increased weight percent of moisture and water soluble proteins compared with the weight percent of moisture and water soluble proteins in the liquids stream, and the light phase containing an increased weight percent of tallow compared with the weight percent of tallow in the liquids stream;
(d) feeding the solids stream from the decanter and the heavy phase from the separator to a mixing point;
and
(e) combining the solids stream and the heavy phase at the mixing point to provide a meat product.
