2.7. Color measurement
The color of fermented mushrooms was measured using an
UltraScan® XE meter (HunterLab, USA). The color values were
expressed as L values (lightness), a values (redness) and b values
(yellowness) units.
2.8. Sensory evaluation
Sensory evaluations of fermented (for 18 days) mushrooms
were done by 10 faculty and students from the College of Food
Science and Technology, Huazhong Agricultural University. Samples
were coded with random numbers and acceptability ratings
for appearance, flavor, texture and overall on a 10-point hedonic
scale (10 ¼ like extremely, 5 ¼ neither like nor dislike, 1 ¼ dislike
extremely).
2.9. Statistical analysis
The data collected reflect the results of three repetitions. The
results were expressed as mean values and standard deviation (SD).
Analysis of variance was performed using a one-way analysis of
variance (ANOVA), and differences between the means of samples
were analyzed by Duncan's test at a significance level of 0.05.
