*: Mean ± standard error.
Means with different letters (a-c) within each parameter in the same column are significantly different (p<0.05).
Means with different letters (A-D) within a row are significantly different (p<0.05).
C: Control (without microbial starter culture) fermented at 25°C.
LP: Inoculated with L. plantarum and fermented at 20, 25, and 30°C.
CSC: Inoculated with commercial starter culture fermented at 25°C.
LP + CSC: Inoculated with a mixture of L. plantarum and commercial starter culture fermented at 25°C.
