Effect of thawing and cold storage on frozen chicken thigh meat quality by high-voltage electrostatic field.
One of the most popular issues in electrostatic biology is the effects of a high-voltage electrostatic field (HVEF) on the thawing of chicken thigh meat. In this study, chicken thigh meat was treated with HVEF (E-group), and compared to samples stored in a common refrigerator (R-group), to investigate how HVEF affects chicken thigh meat quality after thawing at low temperature storage (-3 and 4 degrees C). The results showed that there were no significant differences in biochemical and microorganism indices at -3 degrees C. However, the HVEF can significantly shorten thawing time for frozen chicken thigh meat at -3 degrees C. After thawing chicken thigh meat and storing at 4 degrees C, the total viable counts reached the Intl. Commission on Microbiological Specification for Foods limit of 10(7) CFU/g on the 6 and 8 d for the R- and E-group, respectively. On the 8th d, the volatile basic nitrogen had increased from 11.24 mg/100 g to 21.9 mg/100 g for the E-group and 39.9 mg/100 g for the R-group, respectively. The biochemical and microorganism indices also indicated that the E-group treatment yielded better results on thawing than the R-group treatment. The application of this model has the potential to keep products fresh.
