Summary: | The physicochemical characteristics, texture profiles and consumer acceptance of rice pan bread with various levels of water roux starter (Tangzhong) were investigated. Water roux starter (1.5–6.0%, flour base) was added to the bread dough. The bread samples containing water roux starter had significantly higher moisture contents and specific volumes (P < 0.05). Water roux starter results in the bread having lower hardness, gumminess and chewiness, but there was no significant difference in cohesiveness and springiness. The results of the consumer acceptance test showed that the subjects were split into two groups; one consumer group (52.3%) preferred the bread with 4.5% and 6.0% (flour base) of water roux starter, and the other group (47.7%) preferred the control sample. Adding water roux starter decreased hardness of the bread so that it met the more than 50% of consumers who preferred soft texture. The textural change by adding water roux starter showed positive consumer acceptance in the rice pan bread.
Practical Applications
Texture of pan bread is one of key factor for bread quality. Additional ingredients such as glyceryl monostearate, various gums and/or methyl cellulose to make pan bread soft and glutinous are not necessary when water roux starter was applied in rice pan bread. Water roux starter can be applied to other bread making for baking soft and glutinous bread without any additional additives. In addition, water roux starter in the bread was effective in making same volume of bread with few amounts of ingredient, which is beneficial to bakery industry. |
