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。

摘  要:
pH and drip loss of pork samples at 45 min postmortem and after 24h 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.
