1、2012屆畢業(yè)生畢業(yè)論文題目:蘋果膳食纖維對(duì)法式小面包品質(zhì)的影響及面包工藝設(shè)計(jì)院系名稱:國(guó)際教育學(xué)院專業(yè)班級(jí):學(xué)生姓名:學(xué)號(hào):指導(dǎo)教師:教師職稱:2012年5月28日摘要本課題旨在研究蘋果膳食纖維的添加對(duì)法式小面包品質(zhì)的影響,制作出營(yíng)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(gè)水平,制作法式小面包。通過測(cè)定和分析法式小面包各個(gè)特性數(shù)值(包括產(chǎn)率、比容、感官評(píng)價(jià)、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100目篩的蘋果纖維要優(yōu)于過60目篩的;隨著蘋果纖維添
2、加量的增加,法式小面包的產(chǎn)率增大,白度減小,比容變??;蘋果纖維的增加會(huì)使小面包的感官評(píng)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(shí),感官評(píng)分大幅下降,變得不能接受。蘋果纖維的添加會(huì)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(shí)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15min,壓面25次,醒發(fā)100min,烘烤時(shí)上火175℃,下火150℃,時(shí)間為15min。關(guān)鍵詞法式小面包蘋果膳食纖維烘焙品
