| الملخص: | Oyster mushroom is an edible mushroom that gained popularity lately due to its good
nutritional values. Proximate composition of grey and white oyster mushroom flour
(GOMF and WOMF, respectively) were determined in the study. Then, composite
steamed buns were prepared using either GOMF or WOMF. Wheat flour was partially
substituted with GOMF or WOMF at 3 and 5% (w/w) to prepare 3GOM, 3WOM,
5GOM, and 5WOM, respectively. Steamed bun without GOMF and WOMF served as
control. Prepared steamed buns were evaluated for the physical properties (i.e., water
activity, weight, volume, specific volume, and texture profile), nutritional values (i.e.,
proximate composition, total starch, and resistant starch), and sensory attributes. The
results showed significant difference (P < 0.05) in moisture, ash, crude protein, crude fat,
total carbohydrate, and calorie contents between GOMF and WOMF. All the composite
steamed buns indicated significantly higher (P < 0.05) ash, crude protein, crude fat, and
crude fibre contents, but, significantly lower (P < 0.05) total carbohydrate content than
that of the control steamed bun. Composite steamed buns resulted in a significant increase (P < 0.05) in resistant starch content. Composite steamed buns showed a
significantly darker (P < 0.05) skin and crumb colour, significantly lower (P < 0.05)
volume and specific volume, and significantly higher (P < 0.05) hardness values than that
of the control steamed bun. Sensory evaluation indicated that the substitution of GOMF
or WOMF for wheat flour at 3 and 5% levels, did not significantly affect (P > 0.05) the
overall acceptability on steamed bun by sensory panellists. In general, partial substitution
of either GOMF or WOMF for wheat flour could improve the nutritional quality of the
steamed bun. |
