Abstract
Abstract A restructured meat product in the form of small pieces is made from a comminute of raw meat by incorporating in the comminute fibres of set protein, extruding the fibrous comminute thus obtained through a plurality of holes while transversely shearing the comminute at the entrances to the holes, heat setting the resulting coherent strings of extrudate, and then mechanically working the heat-set strings to break them at points of weakness and form small pieces such as sticks or granules.

Total Claims: 5
Claim 1
Independent Claim
184 words
A METHOD OF MAKING A RESTRUCTED MEAT PRODUCT IN THE FORM OF SMALL PIECES FROM A COMMINUTE OF RAW MEAT, COMPRISING: I. INCORPORATING IN THE RAW MEAT COMMINUTE FIBERS OF SET PROTEIN IN AN AMOUNT FORMING FROM ABOUT 5 TO ABOUT 50% BY WEIGHT OF THE COMMINUTE, II. EXTRUDING THE COMMINUTE THUS OBTAINING THROUGH A PLURALITY OF HOLES WHILE TRANSVERSELY SHEARING SAID COMMINUTE AT THE ANTRANCE TO SAID HOLES, THE RATE OF EXTRUSION OF SAID COMMINUTE AND THE TIME OF SHEARING OF SAID COMMINUTE BEING SO RELATED AS TO PROVIDE SUCCESSIVE ELEMENTS OF DESIRED SIZE, FOLLOWED BY REUNIFYING SAID ELEMENTS SO THAT THERE ISSUES FROM THE EXIT OF EACH OF SAID HOLES A COHERENT STRING OF EXTRUDATE HAVING SPACED ALONG ITS LENGTH LINES OF WEAKNESS RESULTING FROM SAID SHEARING AND SAID REUNIFYING OF SAID ELEMENTS, III. HEAT-SETTING SAID COHERENT STRINGS OF EXTRUDATE AT A TEMPERATURE SUFFICIENT TO PREVENT SAID HEAT-SET STRINGS FROM ADHERING TO ONE ANOTHER DURING SUBSEQUENT MECHANICAL WORKING, AND IV. MECHANICALLY WORKING SAID HEAT-SET STRINGS OF EXTRUDATE TO BREAK SAID STRINGS AT SAID LINES OF WEAKNESS TO FORM GRANULES OR STICKS THEREOF.
