- 摘要:
- 研究了黑龙江省小麦品种龙麦26 和龙辐麦12 在四个加水量水平28 %~ 40 %下的鲜加盐白面条(FWSN)制作与色泽。结果表明, 两个品种FWSN 加水量在28 %~ 32 %时, 亮度(L*)显著降低, 黄度(b*)显著增大;加水量在32 %~ 45 %时, L *值升高, b*值降低。两个品种FWSN 放置24h 后, 随着加水量提高, L*值降低, 红度a *值显著增加, b*值变化不大。在加水量28 %, 放置3 h和24 h , FWSN 的L*值较高。FWSN 在储藏期间色泽稳定性和保持性很关键。结果表明, 两个品种放置3 ~ 72 h , FWSN 的L*值显著降低。对于不同地点种植的龙麦26 和龙辐麦12 , 蛋白质含量与FWSN 的L*值显著负相关(r =-0. 446 , p =0. 05)。随着出粉率提高, FWSN 的L*值显著降低。不同地点种植的龙麦26 和龙辐麦12 , 多酚氧化酶活性对FWSN 色泽影响不大。
