Abstract
The effects of high hydrostatic pressure processing (HHP at 200, 400 or 600 MPa) on non-volatile and volatile compounds of squid muscles during 10-day storage at 4 °C were investigated. HHP increased the concentrations of Clâ and volatile compounds, reduced the level of PO43â, but did not affect the contents of 5â²-uridine monophosphate (UMP), 5â²-guanosine monophosphate (GMP), 5â²-inosine monophosphate (IMP), Na+ and Ca2+ in squids on Day 0. At 600 MPa, squids had the highest levels of 5â²-adenosine monophosphate, Clâ and lactic acid, but the lowest contents of CMP and volatile compounds on Day 10. Essential free amino acids and succinic acids were lower on Day 0 than on Day 10. HHP at 200 MPa caused higher equivalent umami concentration (EUC) on Day 0, and the EUC decreased with increasing pressure on Day 10. Generally, HHP at 200 MPa was beneficial for improving EUC and volatile compounds of squids.
