两种解冻温度下高压静电场对维持猪肉品质的影响
Effect of High-voltage Electrostatic Field on Keeping Pork Quality at Two Thawing Temperatures
摘要
Abstract
To investigate the effect of the high-voltage electrostatic field on maintaining pork quality at two thawing temperatures,the frozen pork is placed in two refrigerators:an ordinary refrigerator(0 kV)(RT)and a refrigerator with a high-voltage electrostatic field(3.75 kV)(HRT).After thawing at 0℃and 10℃for 48 hours,the quality changes of pork before and after thawing are examined by measuring the water holding capacity,microorganisms,physical properties,oxidation and rancidity.The results showed that the drip loss,aerobic plate count and TVB-N of samples of HRT are significantly decreased at 0℃and 10℃compared with RT,while the hardness is significantly increased.The relaxation time of the flow loss of immobilized water(T22)and free water(T23)for HRT at 10℃obviously shifted to the right,and the flow loss of immobilized water is reduced.The redness value(a*)of 0℃HRT is higher than that of RT,while the yellowness value(b*)of 10℃HRT is lower than that of RT.Meanwhile,there is no significant difference in pH,malondialdehyde and other quality indices.关键词
