Chemical Charactersitics and Texture of Tempe Processed with High Pressure Carbon Dioxides

The chemical compositions of tempe indicated their typical characteristics. As a result, the micro or macromolecule changes were likely to produce difference characteristic of tempe. High pressure carbon dioxide was a non-thermal processing method that could retain nutrition qualities, but it affects nonpolar and non covalent bond of substances. This research was conducted to evaluate chemical characteristics of tempe after being processed with high pressure carbon dioxides. The experimental design was carried out in factorial completely randomized design with two factors, that were pressure at 7,6 MPa and 6,3 MPa, and holding time for 5, 10, 15, and 20 minutes. The proximate, calcium, vitamin B and texture were determined in control and treated tempe. The results showed that the treatments of pressures, the the textures. The high pressure of both 7,6 MPa and 6,3 MPa sharply reduced the fat content of all the treated tempe and water content as well. It was only the pressure of 7,6 MPa decreased the protein content. The high pressure treatments increased the calcium of treated tempe but they did not affect the vitamin B-1, B-2, B-3
