Abstract
Sensory evaluation and demonstration of some common bean dishes were conducted.
Boiled common bean was added into triangular shaped kitta(bread) and boiled to prepare
sambusa(snack food in Ethiopia). For kik preparation, Common bean passed all the
necessary steps similar to that of shro but the difference is common bean dehulled, roasted
and slightly milled. Flavor boosting ingredients prepared and mixed with cooked common
bean to prepare ful( breakfast food in Ethiopia) usually prepared from faba bean and
consumed with bread. There was no significant difference in sensory characteristics using
a five-point hedonic scale of prepared dishes. Sensory evaluation indicated that overall
acceptability decreased as common bean processed into flour due to its beany flavor.

Introduction
Common bean (Phaseolus vulgaris L.) is one of most important legume crops grown in all continents of the world. It belongs to family Leguminosae. (Broughton et al.,.2003). Total production exceeds 23 million Metric tons (MT) of which 7 million MT were produced in Latin America and Africa [1]. In Ethiopia, the crops have been cultivated in different parts, mainly at central, eastern, and southern parts of the country. The area under common bean production in Ethiopia is currently 673,847.61 hectare (32.2%) with the total dry bean production of 845116.905 tons (25.7%) [2].
common bean is a staple food that does not require any industrial processing; it is the most important protein source in the developing world and, besides the caloric intake, common bean also provides minerals, fiber, thiamine, folate, and phytochemicals with analgesic and neuroprotective properties [3,4].
In Ethiopia common bean is mostly consumed as mixture of other food grains as flavor
booster which is locally called Nifro. It is important for the consumers to be aware of different
types of dishes prepared from this crop. It is also important for small-scale cafeteria holders
to know how to utilize regarding to their daily utilization for making different food types
such as bread, sambusa, kikwot, shirowot (souse) and ful. Diversified bean products are
crucial in order to make farmers benefited from safe food products and thereby to enrich
daily diet. Assessed sensory characteristics were (color, taste, flavor, mouth feel/texture
and overall acceptance) by using five point hedonic scale (1= Dislike very much, 2= Dislike,
3= neither like nor dislike, 4 = Like and 5= Like Very much). Hence, the objective of this
paper is to evaluate sensory acceptability and demonstrate some common bean dishes.
Materials and Methods
Common bean of locally available variety was collected from local markets of Laska town, Basket special woreda, sothern Ethiopia. For demonstration and sensory evaluation purpose a total of 30 females were selected from Basketo special woreda. Participants whose age is in between 18 to 40 were used for sensory evaluation after permission obtained from local administrator of the study area.
Results are presented as mean±SD , where A= shiro, B= kikwot, C=
Sambusa, D=Ful, NS= non signficant

Result and Discussion
In the present study, common bean of different locally available varieties were used for demonstration of dishes such as sambusa, kikwet, shro wet and ful. Preference ranking method was used. Food samples have the order of ranking as common bean ful first by all the sensory parameters such as color, taste oudor, texture and over all acceptability. The reason behind is for ful preparation common bean was sorted , washed, soaked for 24 hours and mixed with different flavor boosting such as salt, onion, oil, garlic , processed hot pepper and these are prepared as sauce. Shiro is relatively less accepted dish from common bean based on sensory evaluation results. This is in line with similar study conducted on effect of processing method on sensory characteristics of biofortified common bean flour [5]. This is also may be due to people are not aware of common bean shiro and one of the sensory parameter has negative effect on shiro sensory acceptance is its beany nature which is common for legumes. During sensory evaluation and demonstration evaluators mentioned that common bean dishes are acceptable and none of the participants disliked much the prepared common bean dishes.
Four food samples of common bean were evaluated for their
sensory attributes such as color, texture, odor, taste and general acceptability. Totally 30 female farmers participated on sensory
evaluation of common bean dishes feed backs were collected. Due
to untrained panelists consumers oriented how to conduct sensory
evaluation. Before any action materials kept clean and to reduce
intra communication among the evaluators care has taken as much
as possible. Assessors used water to clean their mouth before and
after conducting sensory evaluation. According to farmer’s sensory
evaluation of dishes using five point hedonic scales and preference
ranking method to put in order of sensory acceptance. Common bean
“ful” ranked 1st, “kikwet” 2nd, common bean “sambusa” 3rd and common
bean “shiro” ranked 4th. All the food samples prepared from common
bean scaled above three from total of five point hedonic scales.
Analysis indicated that among four food products prepared common
bean “ful” has got highest acceptance by all sensory parameters
except for its color. Next to “ful”, “kik” wet of common bean ranked
second by all sensory parameters except for its taste. “sambusa”
and “shro” of common bean ranked third and fourth respectively.
However, “sambusa” got highest general acceptance than “shro” by
taste, texture and odor it got least acceptance by its color [6-11].
Conclusion and Recommendation
Common bean being the versatile crop, farmers can prepare different local foods such as “ful”, “kik” “Sambusa”, “shro” and other possible dishes. This is because common bean do not require any industrial processing to prepare different kinds of dishes in household level.
Overall acceptability decreased as common bean milled due to its
beany flavor. It is therefore recommended that flavor boosting agents
can be added to reduce the beany taste. Being beany is the natural
characteristics of legume crops such as common bean.
