AI Technical Summary
Technical Problem
Existing technologies cannot effectively degrade aflatoxins AFB1, AFB2, AFG1, and AFG2 in corn steep liquor simultaneously, and the high viscosity of corn steep liquor makes the drying process difficult, affecting efficiency and product quality.
Method used
Fermentation is carried out using Aspergillus niger strain. Through fermentation and drying, corn steep liquor is degraded toxins, reduced in viscosity, and improved in flavor.
Benefits of technology
It achieves efficient removal of four types of aflatoxin, reduces the viscosity of corn steep liquor, improves drying efficiency and product quality, enhances palatability, and reduces transportation and storage costs.

Abstract
本发明公开了一种低毒素低粘性具有特殊风味玉米浆干粉的生产方法，属于生物技术领域。本发明在玉米浆中接种相应比例的106cfu / mL黑曲霉孢子悬液，以一定的转速和温度进行培养一段时间后，不仅有效的降低了玉米浆的粘度还显著降低了玉米浆中黄曲霉毒素的污染，其中AFB1的降解率可达52.14％、AFB2的降解率可达80.21％、AFG1的降解率可达86.31％、AFG2的降解率可达80.22％。发酵后的玉米浆经干燥后其蛋白质含量和总氨基酸含量都得到了提升，且可以干燥为玉米浆干粉。该发明为玉米浆安全高效利用提供了技术参考，大大降低了玉米浆运输费用，延长产品储存期限，提高使用方便性。
