摘要: 采用两种不同淀粉酶(麦芽糖淀粉酶、α-淀粉酶)和两种不同亲水亲油平衡(hydrophilic lipophilic balance,HLB)值的蔗糖酯(S-1670、S-570)进行蛋糕品质改良研究,通过面糊表面张力与密度分析、质构分析、低场核磁分析和热分析法等多种手段对海绵蛋糕面糊界面特性、烘焙与贮藏特性进行评价。结果表明,HLB值为16的蔗糖酯可以减小面糊体系密度,降低表面张力,从而增强起泡性能和持水能力。低场核磁共振和差示扫描量热法结果表明,同时引入两种不同淀粉酶比使用单一淀粉酶与HLB值为16的蔗糖酯的协同作用效果更佳,其中横向弛豫时间T22从8.521?ms缩短至4.501?ms,蛋糕老化速率k值从0.041?d-1降低至0.035?d-1,这表明它们能增加蛋糕体系持水能力,减缓老化速率,从而提高了在4?℃条件下贮藏35?d后的海绵蛋糕品质。HLB值为16的蔗糖酯作用效果在0~21?d表现较好,而淀粉酶的作用效果则在贮藏后期的21~35?d表现突出。

Abstract: The effect of two different enzymes (maltogenic amylase and α-amylase) and two sucrose esters with different hydrophilic lipophilic balance (HLB) values (S-1670 and S-570) on batter interface properties and baking and storage characteristics of sponge cake. The results showed that the foaming ability and water-holding capacity of cake batter containing sucrose ester with an HLB value of 16 (S-1670) increased because of its decreased density and surface tension compared to the blank control. The low-filed nuclear magnetic resonance (LF-NMR) and differential scanning calorimetric (DSC) data showed that the system containing simultaneously both enzymes and sucrose ester S-1670 had shorter relaxation time T22 (4.501 ms) and lower staling rate (0.035 d-1) compared to 8.521 ms and 0.041 d-1 for that containing maltogenic amylase alone, thereby improving the quality of sponge cake after 35 d of storage at 4 ℃. Sucrose ester S-1670 exerted its effect during the first 21 days of storage, while the enzymes exerted their effect from day 21 to 35.
