Different solutions did not influence (p N 0.05) the texture of the
product. Nevertheless, LSHA (low salt and high acid) samples showed
a tendency for lower values, but not statistically significant. There was
significant difference (p b 0.05) among samples treated with 600 MPa
and the other samples. Samples treated with 600 MPa were harder than the others. Ke et al. (2009) found 34.8 N in Semitendinosus muscle
marinated with citric acid but without HPP. The beef samples in the
present study showed more than twice as much as this value 73 N of
shear force when treated with 600 MPa of pressure. Grossi, Bolumar,
Søltoft-Jensen, and Orlien (2014) studied protein modification in pork
semitendinosus muscle treated with 600 MPa for 6 min. They also
found an increase in hardness of HPP applied samples and attributed
this increase to the aggregation of proteins/peptides resulting in toughening
of the texture and decreased tenderness.
