摘　　要：以20%的马铃薯全粉替代小麦粉制备面包,在不同品类改良剂单因素试验的基础上,选取3种具有显著良性变化的改良剂进行正交试验,得到最佳复配改良剂的配比。试验结果表明,最佳复配改良剂的比例为单甘酯1.5%,脂肪酶0.01‰,抗坏血酸0.05‰。按此配方做出的面包产品体积与对照组产品相比,体积增加83.5%;在老化试验中与对照组相比硬度变化改善71%。复配改良剂能够明显改善马铃薯面包面团的持气性和成品老化速率,对延长马铃薯面包货架期、推进马铃薯原料主食化具有重要意义。On the basis of the single factor experiment of different kinds of bread improvers,the bread samples were made by using the 20 % potato flour instead of wheat flour. And the orthogonal experiment was carried out from three improvers with the significant positive effects to explore the optimal formula of compound bread improvers. The results showed that the optimal compound improvers formula was 1.5 % monoglyceride,0.01 ‰ lipase and 0.05 ‰ ascorbic acid. According to this formula,the loaf volume of the bread with potato flour increased by 83.5 % as compared with the control,and the hardness value of this bread reduced by 71 % as compared to the control. In conclusion,the compound bread improvers could significantly improve the gas retention in bread dough and reduce the aging rate of the bread,which was of great important significance to prolong the shelf life of potato bread and promote the development of potato staple food.
