INULIN AND OLIGOFRUCTOSE INFLUENCE ON THIAMINE LEVEL IN RAT BLOOD SERUM AND URINE

The aim of the study was to estimate the effect of 5% and/or 10 % of inulin and/or oligofructose on thiamine level in blood serum and urine. The vitamin was administered in doses of: 20 or 40 μg/day/rat. With respect to the control (fructan-free), the diet containing 5% of inulin decreased (p<0.05) serum thiamine level when the lower daily vitamin dose was used, and oligofructose had no influence. It was observed that all experimental diets decreased urine thiamine level (p<0.05), which remained stable until the 9th day of the experiment. Then, after next 3 days, the urine thiamine increased, except for the I-5 group with 20 μg daily thiamine dose. The diet with 5% of oligofructose increased (p<0.05) average daily thiamine excretion when rats consumed 20 μg of vitamin per day. Oligofructose was demonstrated to be capable of improving thiamine nutritional status in thiamine-malnourished rats.
