[0152]The restructured meat pieces were prepared by grinding the frozen animal by-products. After grinding, the mix of meat particles was conveyed to a mixing tank in which the meat was mixed until uniform, and was heated to facilitate pumping of the meat mix. The uniform mix of ground meat particles was then comminuted under conditions which emulsify the meat material and form a meat emulsion in which the protein and water of the meat mixture form a matrix that encapsulates the fat globules.

[0163]A feeding trial was conducted with the two wet cat food products (Product 1 and Control 1) of Example 1. In these feeding trials called “two-bowl test” or “versus test” the two products were presented simultaneously to a group of cats. Identical amounts of product were served in each of the two bowls. In the feeding trials the cats were twice exposed to the two products. The position of the two bowls was switched in the second exposure to avoid any bias. The quantity eaten was measured after a single meal exposure. Statistical analyses (Analysis of variance) were made on the data to determine the statistical significance of the observed differences. The outcome of the feeding trial is summarized in Table 6.

[0166]The restructured meat pieces were prepared as follows. Blocks of frozen meat and meat by-products were tempered overnight before being ground. The grounded meat was mixed with the dry and liquid ingredients in the proportions outlined in Table 7. Next, the mixture was emulsified in a bowl chopper. The resulting fine emulsion was transferred to a form press to produce an emulsion sheet that was passed through a steam tunnel with a residence time of two minutes. Temperature of the raw emulsion was raised to about 82° C. at the steam tunnel discharge. The cooked, firm she...
