Abstract

In the present study, we have investigated the bioavailability of biotransformed organic zinc enriched dahi in vivo. The results evidence that the rats fed with zinc enriched dahi (ZED and ZEP) significantly increased (p<0.001) body weight and food intake from zero to third weeks. Analysis of zinc by AAS in body parts of different rat groups indicated that zinc content was significantly higher (p<0.001) in serum, femur bone, liver and hair of rats fed ZED/ZEP. Basal diet and inorganic zinc sulphate fed rat group excreted a greater amount of zinc in faeces. The results of in-vivo studies indicated that the bioavailability of organic zinc through dahi/probiotic dahi is high compared to its inorganic form.

摘要

在本研究中,我们调查了生物转化的富有机锌达希(一种印度酸奶)在体内的生物利用度。结果表明,喂食富锌达希(ZED和ZEP)的大鼠在从零周到第三周期间体重和食物摄入量显著增加(p<0.001)。通过原子吸收光谱法(AAS)对不同大鼠组身体部位的锌进行分析表明,喂食ZED/ZEP的大鼠血清、股骨、肝脏和毛发中的锌含量显著更高(p<0.001)。基础饮食组和喂食无机硫酸锌的大鼠组粪便中排出的锌量更多。体内研究结果表明,与无机形式相比,通过达希/益生菌达希摄入的有机锌生物利用度较高。
