Fat intake has been associated with increased risk of cardiovascular disease, obesity, and diabetes. The
aim of this study was to reformulate meat products using amorphous cellulose fiber (Z-trim®) as a fat
substitute. Based on a Response Surface Methodology, an emulsified and cooked meat model system was
carried out with a standard formulation with 20 g/100 g pork fat, and replacement levels of pork fat
(from 0 to 20 g/100 g) by amorphous cellulose fiber (from 0 to 1.5 g/100 g). The independent variables
within the levels studied influenced the dependent variables emulsion stability (from 73.64 to 91.76 g/
100 g), firmness (from 27.32 to 48.02 N), hardness (from 50.86 to 83.00 N), b* color coordinate (14 days)
(from 13.08 to 14.45), and weight loss during storage (from 1.88 to 5.16 g/100 g). Comparing the fitted
models to the results of the standard sample, it is possible to obtain products with 1.3 g/100 g amorphous
cellulose fiber and 10 g/100 g pork fat (50% fat reduction), with technological characteristics similar to
the standard sample.
