The effect of fermentation time on the characteristics of the perceived
aroma and the total released volatiles produced by T. viride EMCC-107 in
SSF on sugarcane bagasse are shown in Table 1. Strong coconut aroma
was perceived after incubation for 5 d. The intensity of coconut aroma
decreased after 7 d. After 9 d the odor was rather weak coconut/fruity.
Whereas, after 12 d odor of the culture possessed slight sweet fruity
aroma. It is obvious that, the aroma intensity was correlated with the
yield of total volatiles detected by GC analysis. The effect of varying the
concentration of sugarcane bagasse on the intensity of coconut aroma
was investigated on the 5th d of fermentation that showed the
optimum intensity of coconut aroma and highest yield of volatiles
Table 1. As shown in Fig. 3, the optimum intensity of coconut aroma
was perceived by using 4.5 g of sugarcane bagasse as solid substrate
