| 摘 要： | 从玉米浆中筛选出耐50 ℃高温的嗜热乳酸菌，绘制其生长曲线和产酸曲线。然后以10%的接种量接入玉米浸泡水中，研究嗜热乳酸菌对玉米浸泡效果的影响。结果表明，嗜热乳酸菌发酵液可有效提高玉米的吸水率和淀粉得率，玉米吸水饱和所需要的时间由传统工艺的20 h缩短为10 h，淀粉得率由传统工艺的59.22%提高到63.23%。 |
| 关 键 词： | 玉米吸水率 玉米浸泡 嗜热乳酸菌 淀粉得率 |

| Abstract: | We screened out high temperature (50℃) resistant Thermophilic lactobacillus strain from corn steep liquor, and drew its growth curve and acid yield curve. We then employed Thermophilic lactobacillus fermentation broth with 10% inoculation size to study the impact of Thermophilic lactobacillus on corn steeping. Results show that Thermophilic lactobacillus fermentation broth can effectively increase water absorption and starch yield of corn. Duration time of corn moisture saturation is reduced from 20 h to 10 h, and starch yield is increased from 59.22% to 63.23%. |
| Keywords: | Thermophilic lactobacillus starch yield corn steeping water absorption rate of corn |
