Properties of Bovine Collagen as Influenced by High-Pressure Processing

Popis výsledku v původním jazyce

The physical properties and structure of collagen treated with high-pressure technologiesnhave not yet been investigated in detail. The main goal of this work was to determine whether thisnmodern gentle technology significantly changes the properties of collagen. High pressure in thenrange of 0–400 MPa was used, and the rheological, mechanical, thermal, and structural properties ofncollagen were measured. The rheological properties measured in the area of linear viscoelasticityndo not statistically significantly change due to the influence of pressure or the duration of pressurenexposure. In addition, the mechanical properties measured by compression between two platesnare not statistically significantly influenced by pressure value or pressure hold time. The thermalnproperties Ton and DH measured by differential calorimetry depend on pressure value and pressurenhold time. Results from amino acids and FTIR analyses show that exposure of collagenous gels tonhigh pressure (400 MPa), regardless of applied time (5 and 10 min), caused only minor changes in thenprimary and secondary structure and preserved collagenous polymeric integrity. SEM analysis didnnot show changes in collagen fibril ordering orientation over longer distances after applying 400 MPanof pressure for 10 min.n
