Abstract
Octopus muscle ( Octopus vulgaris) of different sex was treated for various different simultaneous combinations of pressure (0.1 or 450 MPa), time (15 or 30 min) and temperature (7, 40, 75 or 100 °C). The sex of specimens was not a significant factor. High pressure was effective in reducing the microbial load and the intense autolytic activity in the octopus muscle. Pressurization time was found to be a significant factor for hardness, but neither hardness nor the exudates were reduced by pressurizing at 450 MPa. Progressive raising of the temperature increased the drip loss, while hardness was reduced only at high temperatures. Increasing temperature produced ultrastructural changes relating to softening, but nevertheless, the ultrastructural changes observed after pressurization did not correspond with modifications in shear strength.
