Effects of
different Aspergillus niger strains
on main nutritional components of grape seed in solid-state fermentation were
investigated in this study. Grape seeds were fermented with three different A. niger strains which are ATCC 9142,
ATCC 200345 and ATCC 52172. Fermented and unfermented grape seeds were analyzed
for crude protein, ether extract, ash, crude fiber, neutral detergent fiber (NDF),
and acid detergent fiber (ADF). Unfermented grape seeds (control group) and
fermented groups: FG1 (ATCC 9142), FG2 (ATCC 200345) and FG3 (ATCC 52172) were compared
each other depending on the results of chemical analyses. Crude protein
increased (p < 0.001) with
fermentation in all groups and the highest increases were observed in FG2 and
FG3 groups. Ether extract was similar with control in FG1 group but decreased (p < 0.001) in FG2 and FG3 groups. Ash
content increased (p < 0.001)
through fermentation in all groups, the highest increases were noted in FG2 and
FG3 groups. Crude fiber, ADF, NDF and nitrogen-free extracts (NFE) were
decreased with fermentation in all groups (p
< 0.001). Whereas the highest decreases of NFE were observed in FG1 and FG2
groups, the highest reduction in crude fiber, ADF and NDF were ocurred in FG2
group. These results showed that nutritional quality of grape seeds can be
improved by A. niger solid-state
fermentation and the best results were taken from ATCC 52172.
