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
