| 摘 要： | 研究屠宰后45min与冷却排酸24h后肉样pH值的分布,对pH值所对应的滴水损失的分布规律进行分析。结果表明:屠宰后45min与冷却排酸24h后肉样的pH值存在一定的规律,且与滴水损失存在一定的负相关。通过对不同阶段肉样的pH值分布进行测定,可以预测冷却排酸后肉样的滴水损失。 |
| 关 键 词： | 冷却猪肉 pH值 滴水损失 |

| Abstract: | pH and drip loss of pork samples at 45 min postmortem and after 24 h of chilling were measured, and the relationship between both parameters was analyzed by plotting their experimental values as a function of the number of measured samples. The results showed that pork samples from the two time points displayed a regular distribution of pH values and exhibited a negative correlation between pH and drip loss. Drip loss of chilled pork could be predicted based on the distribution of pH values. |
| Keywords: | chilled pork pH value drip loss |
