摘要:

以燕麦淀粉为基质的脂肪替代品(oat starch-based fat substitutes,OSFS)添加于传统高脂重油蛋糕中,替代重油蛋糕中的部分脂肪,研究OSFS对重油蛋糕品质的影响。结果表明:OSFS在重油蛋糕体系内具备良好的模拟脂肪的功能,水解度(DE值)为2.39、2.93、3.73的质量分数为25%的OSFS都能够很好的替代蛋糕中脂肪,其中2.39为最佳脂肪替代品。DE值为2.39、质量分数为25%的OSFS能够成功替代重油蛋糕中40%以内的脂肪,其中20%脂肪替代量与传统高脂重油蛋糕的各指标最接近,为最佳脂肪替代量。

Abstract:

In this study, the effects of oat starch-based fat substitutes (OSFS) as a partial substitute for fat on texture and the physico-chemical characteristics of high-ratio cake were investigated. OSFS could well simulate the role of fat in high-ratio cake. The additions of 25% OSFS with a DE value of 2.39, 2.93 and 3.73, respectively were all good substitutes for fat and OSFS with a DE value of 2.39 was the best among them. A fat content below 40% in high-ratio cake was successfully replaced by adding the best fat substitute at a concentration of 25%. When 20% of fat was substituted by OSFS, OSFS brought no detectable changes in texture and physico-chemical properties of high-ratio cake, suggesting that the optimum level of fat substitution in high-ratio cake was 20%.

Key words: fat substitutes, DE value, high-ratio cake, physico-chemical properties, texture
