利用微生物发酵马铃薯淀粉渣的研究进展

Potato Starch Residue as a Substrate for Microbial Fermentation

生物技术的进步为马铃薯淀粉渣等食品工业加工副产品的有效利用提供了新的技术手段。马铃薯淀粉渣是马铃薯淀粉生产过程中产生的主要副产物,因其蛋白质含量较低,纤维素、半纤维素和果胶等含量高,所以作为动物饲料利用时营养价值较低。马铃薯淀粉渣来源丰富,可作为微生物发酵生产诸如酶、蛋白质饲料、有机酸以及膳食纤维等高附加值产品的理想基质。发酵技术用于马铃薯淀粉渣的生物转化备受人们的关注,微生物预处理过程不仅改进了底物的利用,而且能解决废弃物带来的环境污染问题。本文综述了近期通过生物技术手段开发马铃薯淀粉渣的高附加值产品及其工艺的研究进展。

Potato starch residue is the major by-product of the potato starch processing industry.It has low nutritive value because of its low protein content and high amounts of cellulose,hemicelluloses and pectin.Due to the abundant output of by-product,it can be used as an ideal substrate for microbial fermentation to product value-added products such as enzyme preparation,protein-enriched animal feed,organic acid and dietary fiber etc.Application of microbial fermentation technology can be an attractive possibility for such bioconversions.The processing by microbial fermentation has not only improving substrate utilization,but also helping to solve environmental pollution problems.This article reviews the recent research progress on the development of value-added products and techniques of potato starch residue by biotechnological means.
