摘要:

以0、15、30、45、60、75、90 d促熟干酪中主要微生物(乳杆菌、乳球菌、肠球菌、微球菌)和游离氨
基酸含量为指标,研究添加复合处理发酵剂和中性蛋白酶促熟干酪成熟过程对游离氨基酸和微生物菌落数的影响。
结果表明,添加处理发酵剂和中性蛋白酶可增加干酪中游离氨基酸含量,添加处理发酵剂可不同程度降低干酪中微
生物菌落数,添加中性蛋白酶对干酪成熟过程中微生物影响不明显(P>0.05)。

Abstract:

Neutral protease and activated starter culture treated with lysozyme followed by ultrasonic were used either
alone or in combination to accelerate cheese ripening. The numbers of dominant microorganisms (lactobacilli, lactococci,
micrococci, and enterococci) and free amino acid contents were measured at 0, 15, 30, 45, 60, 75, and 90 d of ripening. The
addition of the treated starter culture or neutral protease cheese led to an increase in the content of free amino acids in cheese.
The numbers of microorganism colonies were increased to different extents by the former but not significantly affected by
the latter (P > 0.05).

Key words: cheese, acceleration, microorganism, amino acids
