Abstract: 本研究添加不同比例之發酵麵種(0%、10%、20%、30%、40%)製作土司,結果如下:
1.成品體積:添加發酵麵種,以40%之添加量者,成品體積最大;添加麵種比例20%者,成品體積最小。
2.發酵體積:添加40%麵種之30~120分鐘之發酵、產氣速度最快,且150~270分鐘均持續發酵產氣,顯見其發酵耐力、持續力均佳,只要在製作過程掌握時間,讓麵糰於270分鐘(4.5小時)前能進入烤爐烘烤,能得最大體積。
3.物性:添加40% 發酵麵種者,土司硬度最小,彈性最佳,黏聚性最大、最具咬感、不易被咬斷,咀嚼性最小、最易被吞下。添加20% 麵種者,土司硬度最大,黏聚性最小、易被咬斷,其被咀嚼至可吞下所需的力最多,不易吞下。
4.水分含量:添加不同麵種比例,土司之水分含量並沒有差異。
5.麵包揮發性化合物之萃取共出現14種風味物質;5種不同添加比例發酵麵種之麵包其揮發性化合物並無不同。
This study evaluated the effects of Pate fermentee addition (0%、10%, 20%, 30%, 40%), on the dough mixing characteristics and the quality and flavor of toast. The resulrs:
1. bread loaf volume : to add 40% Pate fermentee dough, it makes bread loaf volume the maximum. To add 20% Pate fermentee dough, the bread loaf volume is minimum.
2. Fermentation volume: when the dough ferments 30~120 mins , to add 40% Pate fermentee dough it ferment the most fastest , until 150~270 mins. If you can bake the dough before it ferment 270 mins, the bread loaf volume will keep the maximum.
3. Texture profile analysis : the results shows that the dough with 40% Pate fermentee dough addition had the lowest hardness, the greatest springiness, the highest cohesiveness, the smallest chewiness.
4. Moisture content (%):Pate fermentee dough addition has no significant effect.
5. Volatile compounds contents of bread made by Pate fermentee addition (0%、10%, 20%, 30%, 40%), which were analyzed with a purge-and-trap gas chromatography /mass-spectrometry (GC /MS) technique. Fourteen aromas were identified. The volatile compounds of five type bread were not different.
