研究以富含OPO(1,3-二油酸-2 -棕榈酸甘油三酯)的植物乳脂粉(即OPO-P)为原料,以24月龄幼儿粪便为菌源,采用模拟人体肠道的体外厌氧发酵系统研究不同浓度OPO-P与幼儿粪便微生物互作的效应。对主要肠道菌群数量、益生元指数PI值和B/E值在24 h互作过程中的动态变化进行了研究,评价了不同浓度OPO-P对幼儿肠道微生物的益生效应。结果表明,发现补充不同浓度OPO-P都能促进双歧杆菌、乳酸杆菌的生长,都能抑制拟杆菌和梭状芽孢杆菌的生长,其中7.5 mg/mL组对双歧杆菌的促进作用最显著,且7.5 mg/mL组的PI值在整个发酵过程中始终高于其他组;而B/E值,14.4 mg/mL组在发酵的前8h过程中大于其他组,7.5mg/mL组在发...

OPO is the English abbreviation of 1,3-Dioleoyl-2-palmitoylglycerool. OPO-enriched Plant-oil Formula(OPO-P) was taken as raw materials and feces of 24-month-old infants as bacteria source,to research the effects of different concentrations OPO-enriched Plant-oil formula interacted with infant feces microorganisms by simulating human intestinal anaerobic fermentation in vitro system. The dynamic changes of main intestinal microflora, Prebiotic Index(PI)and Bifidobacterium/Enterobacterium(B/E)value were studied in the 24 h interaction process, th...
