Título: | The effects of high hydrostatic pressure at subzero temperature on the quality of ready-to-eat cured beef carpaccio |
Autor: | Vaudagna, S. R.; González, Claudia B.; Guignon, Bérengère; Aparicio, Cristina CSIC; Otero, Laura CSIC ORCID; Sanz Martínez, Pedro Dimas CSIC ORCID | Fecha de publicación: | 2012 | Editor: | Elsevier | Citación: | Meat Science 92: 575- 581 (2012) | Resumen: | We compared the application of high hydrostatic pressure (HHP) on unfrozen carpaccio (HHP at 20 °C) and on previously-frozen carpaccio (HHP at -30 °C). HHP at 20 °C changed the color. The pressure increase from 400 to 650. MPa and the time increment from 1 to 5. min at 400. MPa increased L* and b* a* decreased only with 650. MPa for 5. min at 20 °C. The prior freezing of the carpaccio and the HHP at -30 °C minimized the effect of the HHP on the color and did not change the shear force, but increased expressible moisture as compared to the untreated carpaccio. HHP at 20 °C was more effective in reducing the counts of microorganisms (aerobic total count at 30 °C, Enterobacteriaceae, psychrotrophs viable at 6.5 °C and lactic acid bacteria) than HHP at -30. o C. With HHP at 20 °C, we observed a significant effect of pressure and time on the reduction of the counts. © 2012 Elsevier Ltd. | URI: | http://hdl.handle.net/10261/82066 | DOI: | 10.1016/j.meatsci.2012.06.002 | Identificadores: | doi: 10.1016/j.meatsci.2012.06.002 issn: 0309-1740 |
