玉米浆中抗营养因子和有毒物质的脱除及其资源化应用

The Removal of Antinutritional Factors and Toxic Substances from Corn Steep Liquer and Its Utilization

玉米浆是玉米淀粉生产过程中产生的副产物,产量大,营养丰富,含有大量的氨基酸、B族维生素和促生长因子,在发酵工程、饲料添加剂和医药等领域发挥了重要作用。由于玉米浆中亚硫酸根离子残留、真菌毒素污染和渗透压高等问题,严重限制了其在各领域中的应用,造成大量浪费,带来环境污染和经济损失。综述了玉米浆所含抗营养因子、植酸和亚硫酸盐的脱除、真菌毒素的污染与控制及玉米浆的资源化利用,如在单细胞蛋白、氨基酸发酵、生物肥料等方面的应用最新进展,旨在为玉米浆的综合利用提供思路。

Corn steep liquer,a byproduct of corn starch production,is highly productive and nutritious,containing a large quantity of amino acids,B vitamins and growth-promoting factors,which plays an important role in fermentation engineering,feed additives and pharmaceuticals.Due to sulfite residue,mycotoxin contamination and other issues,its application in various fields is seriously limited,resulting in resource waste,environmental pollution and economic loss.This paper reviews the techniques for removing antinutritional factors,phytic acid,and sulfites in corn syrup and the pollution,prevention of fungal toxins as well as the most recent application of it in single-cell protein,amino acid fermentation and biofertilizer,aiming to provide ideas for the comprehensive utilization of corn steep liquer and maximize its economic benefits.
