چکیده

OBJECTIVE To determine the effects of high voltage electrical stimulation (HVES, 800 Voltage) on rapid decreases in pH values and improvements in meat quality. METHODS A total of 50 beef carcasses were applied, divided into two groups, one as a control and another for HVES. Meat quality was evaluated based on M. longissimus dorsi by examining pH and temperature levels at 1, 2, 5, 10 and 24 h, while color stability was examined seven days after slaughter. RESULTS HVES decreased the pH values of the meat and accelerated rigor mortis (P<0.05). HVES caused differences in instrumental color values compared with the control groups across the ageing period at 4 °C. CONCLUSION the HVES had positive effects on meat quality and color stability, in contrast to undesirable consumer preferences.

Effects of pH Early Postmortem on Meat Quality in Beef Longissimus

The effects of type (high and low voltages) and time (3, 40 and 60 min postmortem) of stimulation on drip loss and meat color at 24 h post-mortem were determined on M. longissimus dorsi of 38 crossbred steers and heifers. In addition, the effect of pH early postmortem (70 min postmortem) on the rate and extend of meat tenderization was examined. Either high or low voltage stimulation at 3 min s...

Effect of Type and Time of Electrical Stimulation on Drip loss and Meat Colour in Beef Striploin

The effects of type (high and low voltages) and time (3, 40 and 60 min postmortem) of stimulation on the rate of pH decline, drip loss and meat colour at 24 hours were determined on M. longissimus dorsi of 38 crossbred steers and heifers. Either high or low voltage stimulation at 3 min showed a tendency for faster pH decline (p = 0.052) and higher drip loss (p = 0.08), and improved the colour d...

Effect of Rapid Chilling on Beef Quality and Cytoskeletal Protein Degradation in M. longissimus of Chinese Yellow Crossbred Bulls

The objective of this study was to investigate the effect of rapid chilling (RC) on beef quality and the degradation of cytoskeletal proteins. Twenty Chinese Yellow crossbred bulls were selected and randomly divided into two groups. RC and conventional chilling (CC) were applied to left and right sides of the carcasses respectively after slaughtering. To determine whether electrical stimulation...

Effects of high frequency electrical stunning and decapitation on early rigor development and meat quality of broiler breast meat.

Three independent trials were conducted to determine the effects of high frequency electrical stunning followed by decapitation on broiler breast meat rigor development and meat quality. All birds were stunned and half of the birds were killed using a conventional unilateral neck cut, half were killed by decapitation, and both groups were allowed to bleed for 90 s prior to scalding and picking....

Effects of a unique application of electrical stimulation on tenderness, color, and quality attributes of the beef longissimus muscle.

This study evaluated effects of four uniquely applied beef carcass electrical stimulation (ES) treatments on USDA grade factors, muscle color, subprimal purge loss, cooked steak weight loss, and cooked steak tenderness. One side of each (n = 284) beef carcass was subjected to ES using one of four treatments (medium voltage for medium duration, MVMD; medium voltage for long duration, MVLD; high ...
