中文摘要: 以富含多种天然抗氧化活性成分的果蔬为主要原料,利用具有高效脱除胆固醇能力的鼠李糖乳杆菌217-1、217-3 和217-8 菌株发酵制备酵素,并对酵素中总糖、多酚、黄酮等生物活性成分含量及抑制自由基氧化反应的能力进行检测。结果显示,所得酵素与未经发酵的原溶液相比,其抗氧化活性成分多酚含量提高了29.3%,黄酮含量提高了38.9%,核黄素含量提高了7.3%,原花青素含量提高了8.8%,清除自由基的抗氧化能力提高了100%。研究结果表明,复合果蔬经过发酵所得的酵素营养成分和综合抗氧化能力显著提高,在防止脂质过氧化反应,促进细胞增殖,清除体内自由基,预防皮肤早衰、延缓衰老等方面具有重要潜能。
Abstract:Using fruits and vegetables rich in various natural antioxidant active ingredients as main raw materials,Lactobacillus rhamnoides 217-1,217-3 and 217-8,which had the ability to remove cholesterol efficiently,were selected to produce Jiaosu.The contents of total sugar,polyphenols,flavonoids and their ability to inhibit the oxidation of free radicals were determined.Compared with the control solution,the antioxidant active component polyphenols and flavonoids increased by 29.3 % and 38.9 %,riboflavin content increased 7.3 %,proantho cyanidins content increased 8.8 %,free radical scavenging antioxidant capacity increased 100 %.The results showd that the nutrient components and the comprehensive antioxidant ability of the fermentation of compound fruits and vegetables were significantly increased,which could prevent lipid peroxidation,promote cell proliferation and scavenge free radicals in body.The Jiaosu had important potential in preventing premature aging of skin and delaying aging.
