摘要
苦荞食药兼用,具有抗氧化、降血糖和抗动脉硬化等多种生物活性功效,苦荞中富含膳食纤维,目前膳食纤维的研究主要集中于加工工艺和生物活性方面,对发酵苦荞膳食纤维和生物活性的研究较少,该试验基于此,利用黑曲霉液体发酵技术,对苦荞膳食纤维进行加工发酵,并对发酵后的苦荞膳食纤维营养物质和降脂功效进行研究。研究结果表明,发酵前后苦荞膳食纤维中的蛋白质、水分和脂质含量基本保持不变,膳食纤维的总含量基本稳定,但发酵后苦荞膳食纤维中的不可溶性膳食纤维减少,可溶性膳食纤维增加;发酵后苦荞膳食纤维的持水力、持油性和膨胀力均得到了提高,调节高脂饮食小鼠肠道中微生物群落结构能力得到了增强,为发酵型苦荞膳食纤维的功能应用提供了理论基础。
Tartary buckwheat is used as both food and medicine,and has multiple bioactive functions such as anti-oxidation,regulating blood sugar level and anti-arteriosclerosis.Tartary buckwheat is rich in dietary fiber.At present,the research on tartary buckwheat dietary fiber is mainly focused on processing technology and biological activity,with less research on fermented tartary buckwheat dietary fiber and biological activity.Based on this,in this test,Aspergillus niger liquid fermentation technology is used to process and ferment tartary buckwheat dietary fiber,and the nutrients and lipid-lowering effect of the fermented tartary buckwheat dietary fiber are studied.The results show that the content of protein,water and lipid before and after fermentation remains unchanged basically,the total content of dietary fiber is basically stable,but the insoluble dietary fiber in the fermented tartary buckwheat dietary fiber decreases,the soluble dietary fiber increases.After fermentation,the water holding capacity,oil holding capacity and expansibility of tartary buckwheat dietary fiber are all improved,and the ability to regulate the microbial community structure in the gut of mice with high-fat diet is enhanced,which has provided a theoretical basis for the functional application of fermented tartary buckwheat dietary fiber.
