发酵法制备芸豆渣可溶性膳食纤维及其抗运动性疲劳作用研究

Study on Preparation of Modified Soluble Dietary Fiber of Kidney Bean by Fermentation and Its Effect on Anti-exercise Fatigue

  • 摘要: 为了探讨发酵改性后的芸豆渣可溶性膳食纤维对抗运动性疲劳能力的影响。本实验利用复合菌系发酵改性芸豆膳食纤维,测定其发酵前后理化性质,并建立运动性大鼠模型,向大鼠灌胃5.80、2.90、1.45 g/kg的芸豆膳食纤维,通过游泳力竭实验,分析丙二醛、乳酸脱氢酶、超氧化物歧化酶、谷胱甘肽过氧化物酶以及肝糖原、肌糖原的变化,探究其对运动性疲劳的影响。结果显示,改性后的芸豆膳食纤维含量为18.32%,持水力、膨胀力、持油力均有所提高,分别提高了144.83%、80.66%和58.97%。高、中、低剂量组均能延长大鼠游泳力竭时间,与模型组相比,不同剂量组能够显著降低大鼠体内丙二醛含量(P<0.05),且能够显著提高超氧化物歧化酶和谷胱甘肽过氧化物酶的活力(P<0.05),提升肌糖原与肝糖原的含量和储存能力,高剂量组效果最为显著(P<0.05)。综合以上结果,发酵法制备芸豆渣膳食纤维具有抗运动性疲劳的积极作用,且能够提高抗氧化能力、保护肌肉组织和增强运动耐受性,对未来应用于人体作为一种运动型营养补充制剂具有重要意义。

     

    Abstract: To investigate the fermentation of the modified kidney bean dietary fiber influence on sports ability exercise fatigue, The experiment using modified kidney bean dietary fiber composite strains fermentation, the determination of its physical and chemical properties before and after fermentation was researched. And the motility of rats model was established with different doses of kidney bean dietary fiber (5.80, 2.90, 1.45 g/kg) by swimming exhaustion experiments. The changes of urea nitrogen, malondialdehyde, lactate dehydrogenase, superoxide dismutase, glutathione peroxidase, liver glycogen and muscle glycogen were analyzed to explore their effects on exercise-induced fatigue. The results showed that the dietary fiber content of modified kidney bean was 18.32%, and the water holding capacity, swelling capacity and oil holding capacity were increased by 144.83%, 80.66% and 58.97%, respectively. Compared with model group, the high, medium and low dose group could prolong swimming exhaustion time, reduce the MDA content (P<0.05), improve the SOD and GSH-Px activity (P<0.05), and improve the muscle glycogen and the content of hepatic glycogen and store capacity. The effect of high dose group was the most significant (P<0.05). In conclusion, fermented modified kidney bean dietary fiber had a positive effect on anti-exercise fatigue, and could improve antioxidant capacity, protect muscle tissue and enhance exercise tolerance. It was of great significance to use human body as a kind of exercise nutritional supplement in the future.
