摘要:

研究成熟温度和时间对半硬质干酪成熟特性的影响。将干酪分别在4、10、16℃条件下成熟,测定其在90d 内品质变化规律。结果表明,在90d 成熟期内,pH 值先下降后升高,最后趋于稳定;pH4.6 可溶性氮含量和12% 三氯乙酸可溶性氮含量逐渐升高;乳酸菌总数逐渐下降。成熟温度对干酪的感官品质、pH 值、蛋白质的降解和乳酸菌总数影响显著。4℃成熟的干酪,在第90 天时,感官品质达到最好;10℃成熟的干酪,在第45天时,感官品质达到最好;16℃成熟的干酪,感官品质较差。根据感官品质和其他参数的变化规律,确定半硬质干酪的最佳成熟温度为10℃,最佳成熟时间为45d。

Abstract:

The changes in quality characteristics of cheese stored at 4, 10 ℃ or 16 ℃ during 90 days of ripening period was determined. Results revealed that pH exhibited a change trend to first decrease and then gradually increase until a stable platform during ripening period of 90 days. Soluble nitrogen content of semi-hard cheese at pH 4.6 or in 12% trichloroacetic acid exhibited a gradual increase. The total number of lactic acid bacteria exhibited a gradual decrease. A significant effect of ripening temperature on cheese sensory quality, pH, protein degradation and total number of lactic acid bacteria was observed. The best sensory quality of cheese was achieved at 4 ℃ for 90 days of ripening period or at 10 ℃ for 45 days of ripening period. However, weak sensory quality of cheese was observed at 16 ℃ of ripening temperature. Therefore, according to the variation rule of sensory quality and other parameters, the optimal ripening temperature and time for semi-hard cheese are 10 ℃ and 45 days, respectively.

Key words: ripening temperature, ripening time, semi-hard cheese, ripening characteristics
