High hydrostatic pressure (HHP) treatment can influence meat protein conformation and induce protein denaturation, aggregation, or gelation. The means whereby HHP treatment exerts effects on meat protein structure change are due to the rupture of noncovalent interactions with in protein molecules, and to the subsequent re formation of intra- and inter-molecular bonds within or among protein molecules. Depending upon the meat protein system, the pressure, the temperature, and the duration of the pressure treatment, meant can be either tenderized or toughened. Muscles texture variation induced by heat treatment is due to breakage of hydrogen, bonds, whereas changes from high pressure treatment are due to the rupture of hydrophobic and electrostatic interactions. Pressure treatment has little effect on the toughness of connective tissue. Juiciness, springiness, and chewiness are increased upon HHP treatment. Prerigor HHP treatment tenderized meat, whereas tenderizing effects of postrigor HHP treatment are only measureable if pressure and heat treatment are combined. The limitations and future applications of high pressure technology are also discussed.
