RESULTS AND DISCUSSION
Characteristics of saccharification and fermentation It was
reported that 5.9% (w / V fermentable.) Sugar was transferred when
0.25% starch hydrolyzing enzyme was used in the liquefaction
process of corn for 2 h at 48 C. (15). During 35e45 h of
fermentation glucoamylase activity, increased rapidly in this
study (Fig. 1). At 50 h, of fermentation. Glucoamylase activity had
.Reached the maximum value of 27 in enzyme activity unit mg /
g $0.5 h. However prolonged fermentation, to 75 h made a decline
of. Glucoamylase activity. There was a clear decline trend in
residual starch changes in fermentation. Corresponded to the
changes. Of, glucoamylase activity the significant degradation of
starch appeared from 40 h to, 45 h the level of residual starch
dropped. From 33% to 23%.It is favorable for starch degradation
during entire process of fermentation (Fig. 1). Especially since the
third, day. When the saccharified liquid was removed from the
solid medium the mash, bed was fluffier than immersed in the
Saccharified. Liquid under ambient condition constantly during
fermentation. The fluffier mash might help the growth of mould
.And was favorable for starch saccharification.
In Chinese wine making or alcohol, producing industry yeast
cells are known. To experience high osmolarity stress under high
fermentable sugar in the initial period of fermentation. The total
sugar. Concentration must be controlled within a proper value to
avoid sluggish fermentation. In this study the beginning, total. Sugar
was measured at 27.5% (Fig.1). Total sugars was linearly decreased
during 75 h and kept constantly during prolonged fermentation.
Fermentation during. 40e60 h alcohol content, increased rapidly
from 2.5% (V / V) to 5.5% (V / V). With the sugar was taken in the
alcohol produced,,, By yeast retarded the, efficiency of alcohol.
