1、2012屆畢業(yè)生畢業(yè)論文題目:蘋果膳食纖維面包品質(zhì)的影響及面包工藝設(shè)計院系名稱:國際教育學院專業(yè)班級:學生姓名:學號:指導(dǎo)教師:教師職稱:2012年5月28日摘要本題在研究蘋果膳食纖維的添加對法式小面包品質(zhì)的影響,制作出營養(yǎng)美味的法式小面包。采用法式小面包專用粉和金苑特一粉兩種面粉,選用過60目和100目篩的蘋果膳食纖維,添加量為0%,1%,2%,3%,4%五個水平,制作法式小面包。通過測定和分析法式小面包各個特性數(shù)值(包括產(chǎn)率、比容、感官評價、白度和面包內(nèi)部氣孔),得出了以下結(jié)論:專用粉的品質(zhì)要優(yōu)于金苑特一粉;過
2、100目篩的蘋果纖維要優(yōu)于過60目篩的;隨著蘋果纖維添加量的增加,法式小面包的產(chǎn)率增大,白度減小,比容變?。惶O果纖維的增加會使小面包的感官評分下降。主要影響面包的均一性、面包芯色澤、內(nèi)部質(zhì)地和紋理。專用粉添加100目蘋果纖維的法式小面包,在添加量大于2%時,感官評分大幅下降,變得不能接受。蘋果纖維的添加會使法式小面包的氣孔均勻程度下降,出現(xiàn)大氣孔,孔壁變厚。專用粉100目在大于1%時出現(xiàn)明顯大孔。經(jīng)過研究,得出制作法式小面包最佳配方:采用法式小面包專用粉,并添加過100目篩的蘋果膳食纖維,添加量為1%,打面15mi
