The Lactobacillus ferment used in this study was composed of Lactobacillus fermented wheat, barley and kefir grains. Fermentation increased the CFU of lactic acid bacteria with a reduction in pH value and in the contents of dietary fi ber and glucan. Male SD rats were fed a high fat diet with or without 10% Lactobacillus ferment for 4 weeks. In the Lactic-F group (group fed high-fat diet with Lactobacillus ferment) there was a significantly reduced increase of body weight compared with the HF-control (group fed high-fat diet without Lactobacillus ferment). The food efficiency ratio (FER) tended to be decreased in the Lactic-F group, but there was no significant difference between the Lactic-F and HF-control groups. The perirenal and the epididymal fat weights in the normal dietary group (control) and in the Lactic-F group were significantly lower than those of the HF-control. The serum HDL-cholesterol and the total cholesterol in the Lactic-F group were similar to the control group, and were significantly different from those of the HF-control. These results indicated that the Lactobacillus ferment is a functional material having antiobesity effects, with use as a supplement in functional, health-favoring food.
本研究中使用的发酵乳杆菌由发酵小麦、大麦和开菲尔粒的乳杆菌组成。发酵增加了乳酸菌的菌落形成单位,同时降低了pH值以及膳食纤维和葡聚糖的含量。雄性SD大鼠被喂食高脂饮食,其中一组添加10%的发酵乳杆菌,另一组不添加,持续4周。与高脂对照组(喂食不含发酵乳杆菌的高脂饮食的组)相比,乳酸 - F组(喂食含发酵乳杆菌的高脂饮食的组)体重增加显著减少。乳酸 - F组的食物效率比(FER)有降低的趋势,但乳酸 - F组和高脂对照组之间没有显著差异。正常饮食组(对照组)和乳酸 - F组的肾周脂肪和附睾脂肪重量显著低于高脂对照组。乳酸 - F组的血清高密度脂蛋白胆固醇和总胆固醇与对照组相似,与高脂对照组有显著差异。这些结果表明,发酵乳杆菌是一种具有抗肥胖作用的功能性物质,可作为功能性健康食品的补充剂。
