Purpose: This study investigated the quality characteristics of Jeungpyun prepared with brown rice and sea tangle powder.
Methods: The pH, volume, and spreadability of the dough and moisture content, color, texture and sensory evaluation of the Jeungpyun were performed.
Results: The results showed that the pH of the dough decreased in all sample groups with the lapse of fermentation time, and ultimately revealed a pH ranging from 4.55-4.65. The spreadability of the dough significantly decreased as the substitute amount of the brown rice flour increased; the sample group with 1% sea tangle powder showed a significantly larger spreadability than the sample group with 2% sea tangle powder (p<0.05). The moisture content in the Jeungpyun showed a significantly lower result as the substitute amount of brown rice flour increased (p<0.05). Lightness (L) was reduced as the substitute amount of brown rice flour increased, and redness (a) and yellowness (b) also appeared to increase. As a result of measuring the texture, the 50% sample group with a high substitute rate of brown rice flour was observed to have high characteristics of hardness, gumminess and chewiness, and was low in cohesiveness. The result of the acceptance test showed that the sample group that substituted 25% brown rice flour and added 1% sea tangle powder was evaluated to have a significantly higher acceptance than the sample group that added 2% sea tangle powder in terms of color, texture and overall acceptance.
Conclusion: The result of the acceptance test showed that the sample group that substituted 25% of brown rice flour and added 1% of sea tangle powder showed higher tendency in all acceptance attributes than the sample group that did not substitute the brown rice flour to show the possibility of developing the Jeungpyun with brown rice.
