| Summary: | The objective of this study was to determine the effect of different ratios of powder prepared from oyster mushroom to
tapioca flour on the physicochemical properties and sensory acceptability of fried mushroom crackers. Four recipes for crackers
were formulated with varying ratios of oyster mushroom powder to tapioca flour, i.e. 5:95; 10:90; 15:85 and 20:80. The
control sample comprised 100% tapioca flour. Sensory acceptability was performed using an affective test on a 7-point hedonic
scale. Fried mushroom crackers showed significant decreases (p<0.05) in the L* value, oil absorption and hardness, while
the b* value, linear expansion, ash and protein contents increased when the content of oyster mushroom powder was increased
in the crackers. Sensory acceptability of the crackers was significantly improved (p<0.05) with the addition of oyster mushroom
powder as compared with the control. Crackers made with 15% of oyster mushroom powder and 85% of tapioca flour gave
the highest mean score in all the evaluated sensory attributes; they were not significantly different (p>0.05) in these respects
from crackers containing 20% oyster mushroom powder. These results can be useful in the development of vegetarian fried
mushroom crackers that may serve as an alternative to crackers more commonly based on fish or other seafood. |
