Platel, K. | Srinivasan, K.
In an animal experiment, the influence of several spices included in the diet, on food transit time was examined. Groups of adult female Wistar rats were maintained for 6 weeks on diets containing (g%): Curcumin (0.5), Capsaicin (0.015), Piperine (0.02), Ginger (0.05), Cumin (1.25), Fenugreek (2.0), Mustard (0.25), Asafoetida (0.25), Ajowan (0.2), Fennel (0.5), Coriander (2.0), Mint (1.0), Garlic (0.5), and Onion (2.0). On the last day, food transit time was monitored by including ferric oxide (0.5%) in the diet as an un-absorbable marker. Time of excretion of colored faeces was noted following time of consumption of the diet with the marker. In general, all the test spices except fenugreek and mustard produced a significant shortening of the food transit time. This influence was more prominent in the case of spices--ginger, ajowan, cumin, piperine, coriander and capsaicin.
