Abstract

This research aims to determine the effect of oats addition in wheat cookies formulation seen from physical and sensory characteristics. Six formulations used in this research consist of wheat flour and oats mixture namely Control (100%:0%), Formulation 1 (80%:20%), Formulation 2 (60%:40%), Formulation 3 (40%:60%), Formulation 4 (20%:80%), and Formulation 5 (0%:100%). Based on analysis of variance result at α = 5%, there was a significant difference in the value of hardness and work from control and all variation of cookies’ formulation. It was also found that the decreasing composition of wheat flour and increasing composition of oats caused a decrease in the value of hardness and work. The addition of oats in the formulation of wheat cookies increases the level of brightness (L), decreases the value of a* (red tone), and increases the value of b* (yellow tone) of cookies. From sensory evaluation, compared to controls, the addition of oats in the formulation increased the acceptance rating for color parameter for all formulation, taste parameter for Formulation 2 until 5, and overall parameter for Formulation 2 and 3, while for the texture parameter, the addition of oats did not provide an increased in the acceptance rating.

Abstract

Indonesia has variety of fruits that have the potential to be used as botanical water in sourdough bread making, especially those with high sugar content. Salak pondoh (Salacca zalacca var pondoh) is one of Indonesia's native fruits that has a distinctive flavor and is favored by the public. This research aims to utilize botanical water from salak pondoh in the making of sourdough bread. This research method consists of several stages, namely making botanical water, making starter, evaluating yeast activity, and white bread production. The analysis performed on white bread includes physical analysis, chemical analysis, and sensory analysis. Yeast activity in this study showed that the use of sourdough starter with the percentage of 30% had the highest activity level of 1.035 ± 0.002 ml/hour. Proximate test results showed significant differences in protein content, water content, and fiber content, while carbohydrate, fat, and ash content were not significantly different. The results of the texture test showed significant differences for hardness and springiness parameters, while for other texture parameters there were no significant differences. Overall, white bread using sourdough starter from salak pondoh can develop well and can be accepted like white bread in general, even in this study white bread with the addition of sourdough starter obtained a higher hedonic rating compared to white bread sample control.
