However, all food should have left the stomach within 2 to 4 hours. (approx. time spent in stomach before emptying) Liquid: Water-when stomach is empty, leaves immediately and goes into intestines, Juices-Fruit vegetables, vegetable broth - 15 to 20 minutes.
After you eat, it takes about  six to eight hours for food to pass through your stomach and small intestine. Food then enters your large intestine (colon) for further digestion, absorption of water and, finally, elimination of undigested food. In the 1980s, Mayo Clinic researchers measured digestion time in 21 healthy people. Total transit time, from eating to elimination in stool, averaged 53 hours (although that figure is a little overstated, because the markers used by the researchers passed more slowly through the stomach than actual food).
